SRE Doesn’t Scale

We encounter a lot of organizations talking about or attempting to implement SRE as part of our consulting at Real Kinetic. We’ve even discussed and debated ourselves, ad nauseam, how we can apply it at our own product company, Witful. There’s a brief, unassuming section in the SRE book tucked away towards the tail end of chapter 32, “The Evolving SRE Engagement Model.” Between the SLIs and SLOs, the error budgets, alerting, and strategies for handling change management, it’s probably one of the most overlooked parts of the book. It’s also, in my opinion, one of the most important.

Chapter 32 starts by discussing the “classic” SRE model and then, towards the end, how Google has been evolving beyond this model. “External Factors Affecting SRE”, under the “Evolving Services Development: Frameworks and SRE Platform” heading, is the section I’m referring to specifically. This part of the book details challenges and approaches for scaling the SRE model described in the preceding chapters. This section describes Google’s own shift towards the industry trend of microservices, the difficulties that have resulted, and what it means for SRE. Google implements a robust site reliability program which employs a small army of SREs who support some of the company’s most critical systems and engage with engineering teams to improve the reliability of their products and services. The model described in the book has proven to be highly effective for Google but is also quite resource-intensive. Microservices only serve to multiply this problem. The organizations we see attempting to adopt microservices along with SRE, particularly those who are doing it as a part of a move to cloud, frequently underestimate just how much it’s about to ruin their day in terms of thinking about software development and operations.

It is not going from a monolith to a handful of microservices. It ends up being hundreds of services or more, even for the smaller companies. This happens every single time. And that move to microservices—in combination with cloud—unleashes a whole new level of autonomy and empowerment for developers who, often coming from a more restrictive ops-controlled environment on prem, introduce all sorts of new programming languages, compute platforms, databases, and other technologies. The move to microservices and cloud is nothing short of a Cambrian Explosion for just about every organization that attempts it. I have never seen this not play out to some degree, and it tends to be highly disruptive. Some groups handle it well—others do not. Usually, however, this brings an organization’s delivery to a grinding halt as they try to get a handle on the situation. In some cases, I’ve seen it take a year or more for a company to actually start delivering products in the cloud after declaring they are “all in” on it. And that’s just the process of starting to deliver, not actually delivering them.

How does this relate to SRE? In the book, Google says a result of moving towards microservices is that both the number of requests for SRE support and the cardinality of services to support have increased dramatically. Because each service has a base fixed operational cost, even simple services demand more staffing. Additionally, microservices almost always imply an expectation of lower lead time for deployment. This is invariably one of the reasons we see organizations adopting them in the first place. This reduced lead time was not possible with the Production Readiness Review model they describe earlier in chapter 32 because it had a lead time of months. For many of the organizations we work with, a lead time of months to deliver new products and capabilities to their customers is simply not viable. It would be like rewinding the clock to when they were still operating on prem and completely defeat the purpose of microservices and cloud.

But here’s the key excerpt from the book: “Hiring experienced, qualified SREs is difficult and costly. Despite enormous effort from the recruiting organization, there are never enough SREs to support all the services that need their expertise.” The authors conclude, “the SRE organization is responsible for serving the needs of the large and growing number of development teams that do not already enjoy direct SRE support. This mandate calls for extending the SRE support model far beyond the original concept and engagement model.”

Even Google, who has infinite money and an endless recruiting pipeline, says the SRE model—as it is often described by the people we encounter referencing the book—does not scale with microservices. Instead, they go on to describe a more tractable, framework-oriented model to address this through things like codified best practices, reusable solutions, standardization of tools and patterns, and, more generally, what I describe as the “productization” of infrastructure and operations.

Google enforces standards and opinions around things like programming languages, instrumentation and metrics, logging, and control systems surrounding traffic and load management. The alternative to this is the Cambrian Explosion I described earlier. The authors enumerate the benefits of this approach such as significantly lower operational overhead, universal support by design, faster and lower overhead SRE engagements, and a new engagement model based on shared responsibility rather than either full SRE support or no SRE support. As the authors put it, “This model represents a significant departure from the way service management was originally conceived in two major ways: it entails a new relationship model for the interaction between SRE and development teams, and a new staffing model for SRE-supported service management.”

For some reason, this little detail gets lost and, consequently, we see groups attempting to throw people at the problem, such as embedding an SRE on each team. In practice, this usually means two things: 1) hiring a whole bunch of SREs—which even Google admits to being difficult and costly—and 2) this person typically just becomes the “whipping boy” for the team. More often than not, this individual is some poor ops person who gets labeled “SRE.”

With microservices, which again almost always hit you with a near-exponential growth rate once you adopt them, you simply cannot expect to have a handful of individuals who are tasked with understanding the entirety of a microservice-based platform and be responsible for it. SRE does not mean developers get to just go back to thinking about code and features. Microservices necessitate developers having skin in the game, and even Google has talked about the challenges of scaling a traditional SRE model and why a different tack is needed.

“The constant growth in the number of services at Google means that most of these services can neither warrant SRE engagement nor be maintained by SREs. Regardless, services that don’t receive full SRE support can be built to use production features that are developed and maintained by SREs. This practice effectively breaks the SRE staffing barrier. Enabling SRE-supported production standards and tools for all teams improves the overall service quality across Google.”

My advice is to stop thinking about SRE as an implementation specifically and instead think about the problems it’s solving a bit more abstractly. It’s unlikely your organization has Google-level resources, so you need to consider the constraints. You need to think about the roles and responsibilities of developers as well as your ops folks. They will change significantly with microservices and cloud out of necessity. You’ll need to think about how to scale DevOps within your organization and, as part of that, what “DevOps” actually means to your organization. In fact, many groups are probably better off simply removing “SRE” and “DevOps” from their vocabulary altogether because they often end up being distracting buzzwords. For most mid-to-large-sized companies, some sort of framework- and platform- oriented model is usually needed, similar to what Google describes.

I’ve seen it over and over. This hits companies like a ton of bricks. It requires looking at some hard org problems. A lot of self-reflection that many companies find uncomfortable or just difficult to do. But it has to be done. It’s also an important piece of context when applying the SRE book. Don’t skip over chapter 32. It might just be the most important part of the book.

Structuring a Cloud Infrastructure Organization

Real Kinetic often works with companies just beginning their cloud journey. Many come from a conventional on-prem IT organization, which typically looks like separate development and IT operations groups. One of the main challenges we help these clients with is how to structure their engineering organizations effectively as they make this transition. While we approach this problem holistically, it can generally be looked at as two components: product development and infrastructure. One might wonder if this is still the case with the shift to DevOps and cloud, but as we’ll see, these two groups still play important and distinct roles.

We help clients understand and embrace the notion of a product mindset as it relates to software development. This is a fundamental shift from how many of these companies have traditionally developed software, in which development was viewed as an IT partner beholden to the business. This transformation is something I’ve discussed at length and will not be the subject of this conversation. Rather, I want to spend some time talking about the other side of the coin: operations.

Operations in the Cloud

While I’ve talked about operations in the context of cloud before, it’s only been in broad strokes and not from a concrete, organizational perspective. Those discussions don’t really get to the heart of the matter and the question that so many IT leaders ask: what does an operations organization look like in the cloud?

This, of course, is a highly subjective question to which there is no “right” answer. This is doubly so considering that every company and culture is different. I can only humbly offer my opinion and answer with what I’ve seen work in the context of particular companies with particular cultures. Bear this in mind as you think about your own company. More often than not, the cultural transformation is more arduous than the technology transformation.

I should also caveat that—outside of being a strategic instrument—Real Kinetic is not in the business of simply helping companies lift-and-shift to the cloud. When we do, it’s always with the intention of modernizing and adapting to more cloud-native architectures. Consequently, our clients are not usually looking to merely replicate their current org structure in the cloud. Instead, they’re looking to tailor it appropriately.

Defining Lines of Responsibility

What should developers need to understand and be responsible for? There tend to be two schools of thought at two different extremes when it comes to this depending on peoples’ backgrounds and experiences. Oftentimes, developers will want more control over infrastructure and operations, having come from the constraints of a more siloed organization. On the flip side, operations folks and managers will likely be more in favor of having a separate group retain control over production environments and infrastructure for various reasons—efficiency, stability, and security to name a few. Not to mention, there are a lot of operational concerns that many developers are likely not even aware of—the sort of unsung, unglamorous bits of running software.

Ironically, both models can be used as an argument for “DevOps.” There are also cases to be made for either. The developer argument is better delivery velocity and innovation at a team level. The operations argument is better stability, risk management, and cost control. There’s also likely more potential for better consistency and throughput at an organization level.

The answer, unsurprisingly, is a combination of both.

There is an inherent tension between empowering developers and running an efficient organization. We want to give developers the flexibility and autonomy they need to develop good solutions and innovate. At the same time, we also need to realize the operational efficiencies that common solutions and standardization provide in order to benefit from economies of scale. Should every developer be a generalist or should there be specialists?

Real Kinetic helps clients adopt a model we refer to as “Developer Enablement.” The idea of Developer Enablement is shifting the focus of ops teams from being “masters” of production to “enablers” of production by applying a product lens to operations. In practical terms, this means less running production workloads on behalf of developers and more providing tools and products that allow developers to run workloads themselves. It also means thinking of operations less as a task-driven service model and more as a strategic enabler. However, Developer Enablement is not about giving full autonomy to developers to do as they please, it’s about providing the abstractions they need to be successful on the platform while realizing the operational efficiencies possible in a larger organization. This means providing common tooling, products, and patterns. These are developed in partnership with product teams so that they meet the needs of the organization. Some companies might refer to this as a “platform” team, though I think this has a slightly different meaning. So how does this map to an actual organization?

Mapping Out an Engineering Organization

First, let’s mentally model our engineering organization as two groups: Product Development and Infrastructure and Reliability. The first is charged with developing products for end users and customers. This is the stuff that makes the business money. The second is responsible for supporting the first. This is where the notion of “developer enablement” comes into play. And while this group isn’t necessarily doing work that is directly strategic to the business, it is work that is critical to providing efficiencies and keeping the lights on just the same. This would traditionally be referred to as Operations.

As mentioned above, the focus of this discussion is the green box. And as you might infer from the name, this group is itself composed of two subgroups. Infrastructure is about enabling product teams, and Reliability is about providing a first line of defense when it comes to triaging production incidents. This latter subgroup is, in and of itself, its own post and worthy of a separate discussion, so we’ll set that aside for another day. We are really focused on what a cloud infrastructure organization might look like. Let’s drill down on that piece of the green box.

An Infrastructure Organization Model

When thinking about organization structure, I find that it helps to consider layers of operational concern while mapping the ownership of those concerns. The below diagram is an example of this. Note that these do not necessarily map to specific team boundaries. Some areas may have overlap, and responsibilities may also shift over time. This is mostly an exercise to identify key organizational needs and concerns.

We like to model the infrastructure organization as three teams: Developer Productivity, Infrastructure Engineering, and Cloud Engineering. Each team has its own charter and mission, but they are all in support of the overarching objective of enabling product development efficiently and at scale. In some cases, these teams consist of just a handful of engineers, and in other cases, they consist of dozens or hundreds of engineers depending on the size of the organization and its needs. These team sizes also change as the priorities and needs of the company evolve over time.

Developer Productivity

Developer Productivity is tasked with getting ideas from an engineer’s brain to a deployable artifact as efficiently as possible. This involves building or providing solutions for things like CI/CD, artifact repositories, documentation portals, developer onboarding, and general developer tooling. This team is primarily an engineering spend multiplier. Often a small Developer Productivity team can create a great deal of leverage by providing these different tools and products to the organization. Their core mandate is reducing friction in the delivery process.

Infrastructure Engineering

The Infrastructure Engineering team is responsible for making the process of getting a deployable artifact to production and managing it as painless as possible for product teams. Often this looks like providing an “opinionated platform” on top of the cloud provider. Completely opening up a platform such as AWS for developers to freely use can be problematic for larger organizations because of cost and time inefficiencies. It also makes security and compliance teams’ jobs much more difficult. Therefore, this group must walk the fine line between providing developers with enough flexibility to be productive and move fast while ensuring aggregate efficiencies to maintain organization-wide throughput as well as manage costs and risk. This can look like providing a Kubernetes cluster as a service with opinions around components like load balancing, logging, monitoring, deployments, and intra-service communication patterns. Infrastructure Engineering should also provide tooling for teams to manage production services in a way that meets the organization’s regulatory requirements.

The question of ownership is important. In some organizations, the Infrastructure Engineering team may own and operate infrastructure services, such as common compute clusters, databases, or message queues. In others, they might simply provide opinionated guard rails around these things. Most commonly, it is a combination of both. Without this, it’s easy to end up with every team running their own unique messaging system, database, cache, or other piece of infrastructure. You’ll have lots of architecture astronauts on your hands, and they will need to be able to answer questions around things like high availability and disaster recovery. This leads to significant inefficiencies and operational issues. Even if there isn’t shared infrastructure, it’s valuable to have an opinionated set of technologies to consolidate institutional knowledge, tooling, patterns, and practices. This doesn’t have to act as a hard-and-fast rule, but it means teams should be able to make a good case for operating outside of the guard rails provided.

This model is different from traditional operations in that it takes a product-mindset approach to providing solutions to internal customers. This means it’s important that the group is able to understand and empathize with the product teams they serve in order to identify areas for improvement. It also means productizing and automating traditional operations tasks while encouraging good patterns and practices. This is a radical departure from the way in which most operations teams normally operate. It’s closer to how a product development team should work.

This group should also own standards around things like logging and instrumentation. These standards allow the team to develop tools and services that deal with this data across the entire organization. I’ve talked about this notion with the Observability Pipeline.

Cloud Engineering

Cloud Engineering might be closest to what most would consider a conventional operations team. In fact, we used to refer to this group as Cloud Operations but have since moved away from that vernacular due to the connotation the word “operations” carries. This group is responsible for handling common low-level concerns, underlying subsystems management, and realizing efficiencies at an aggregate level. Let’s break down what that means in practice by looking at some examples. We’ll continue using AWS to demonstrate, but the same applies across any cloud provider.

One of the low-level concerns this group is responsible for is AMI and base container image maintenance. This might be the AMIs used for Kubernetes nodes and the base images used by application pods running in the cluster. These are critical components as they directly relate to the organization’s security and compliance posture. They are also pieces most developers in a large organization are not well-equipped to—or interested in—dealing with. Patch management is a fundamental concern that often takes a back seat to feature development. Other examples of this include network configuration, certificate management, logging agents, intrusion detection, and SIEM. These are all important aspects of keeping the lights on and the company’s name out of the news headlines. Having a group that specializes in these shared operational concerns is vital.

In terms of realizing efficiencies, this mostly consists of managing AWS accounts, organization policies (another important security facet), and billing. This group owns cloud spend across the organization and, as a result, is able to monitor cumulative usage and identify areas for optimization. This might look like implementing resource-tagging policies, managing Reserved Instances, or negotiating with AWS on committed spend agreements. Spend is one of the reasons large companies standardize on a single cloud platform, so it’s essential to have good visibility and ownership over this. Note that this team is not responsible for the spend itself, rather they are responsible for visibility into the spend and cost allocations to hold teams accountable.

The unfortunate reality is that if the Cloud Engineering team does their job well, no one really thinks about them. That’s just the nature of this kind of work, but it has a massive impact on the company’s bottom line.

Summary

Depending on the company culture, words like “standards” and “opinionated” might be considered taboo. These can be especially unsettling for developers who have worked in rigid or siloed environments. However, it doesn’t have to be all or nothing. These opinions are more meant to serve as a beaten path which makes it easier and faster for teams to deliver products and focus on business value. In fact, opinionation will accelerate cloud adoption for many organizations, enable creativity on the value rather than solution architecture, and improve efficiency and consistency at a number of levels like skills, knowledge, operations, and security. The key is in understanding how to balance this with flexibility so as to not overly constrain developers.

We like taking a product approach to operations because it moves away from the “ticket-driven” and gatekeeper model that plagues so many organizations. By thinking like a product team, infrastructure and operations groups are better able to serve developers. They are also better able to scale—something that is consistently difficult for more interrupt-driven ops teams who so often find themselves becoming the bottleneck.

Notice that I’ve entirely sidestepped terms like “DevOps” and “SRE” in this discussion. That is intentional as these concepts frequently serve as a distraction for companies who are just beginning their journey to the cloud. There are ideas encapsulated by these philosophies which provide important direction and practices, but it’s imperative to not get too caught up in the dogma. Otherwise, it’s easy to spin your wheels and chase things that, at least early on, are not particularly meaningful. It’s more impactful to focus on fundamentals and finding some success early on versus trying to approach things as town planners.

Moreover, for many companies, the organization model I walked through above was the result of evolving and adapting as needs changed and less of a wholesale reorg. In the spirit of product mindset, we encourage starting small and iterating as opposed to boiling the ocean. The model above can hopefully act as a framework to help you identify needs and areas of ownership within your own organization. Keep in mind that these areas of responsibility might shift over time as capabilities are implemented and added.

Lastly, do not mistake this framework as something that might preclude exploration, learning, and innovation on the part of development teams. Again, opinionation and standards are not binding but rather act as a path of least resistance to facilitate efficiency. It’s important teams have a safe playground for exploratory work. Ideally, new ideas and discoveries that are shown to add value can be standardized over time and become part of that beaten path. This way we can make them more repeatable and scale their benefits rather than keeping them as one-off solutions.

How has your organization approached cloud development? What’s worked? What hasn’t? I’d love to hear from you.

Digitally Transformed: Becoming a Technology Product Company

More and more established businesses are attempting to reinvent themselves as technology companies. At the heart of this is the digital transformation, a journey many organizations are undertaking in order to better compete and serve their customers. As a result, companies are pouring tons of cash into digital transformation strategies. For some, this means broader adoption of agile or DevOps practices. For others, it’s modernizing product offerings or moving to the cloud. Regardless of the changes, many are struggling to find success transforming themselves due to low throughput, quality issues, or failing to deliver the right thing at the right time. In a few cases, digital transformation has ended in outright disaster.

What is it that these companies are really after? To solve new problems in new ways through innovation? To more rapidly adapt to the changing market? To protect existing revenue? Any leader worth their salt will say all of these are important outcomes, so how do you even begin to make a “digital transformation” actionable? What are we transforming to? How do we know when we’ve arrived?

The reason so many digital transformations fail has to do with how IT is usually positioned within mature, established businesses. I believe what these companies are really after is not a digital transformation—whatever that might be—but rather an organizational one that radically changes the way the business operates. One that redefines what IT means in the context of building software. The technology is incidental to this cultural shift which involves the intersection of people, processes, and innovation. In order to be successful, these organizations need to become technology product companies.

The Genesis of IT

There is an inertia within organizations to overvalue tactics and undervalue strategy. This is true not just of mature, established businesses but really all businesses, startups included. In fact, it’s this exact reason most startups fail. A lack of clear strategy and guiding vision precludes even the best execution from delivering success outside of the odd unicorn (after all, someone has to win the Powerball). Established businesses, however, already have a reliable cash flow engine to fall back on. There is much more margin for error when it comes to both strategy and execution, but this peacetime mentality leads to disruption. Many leaders have begun to recognize this and act on it, falling right back to what they know best—tactics.

Why do companies and managers tend to bias towards tactics over strategy in software development? It comes back to the genesis of IT. Historically, IT was about managing computers, networks, email, phone systems, and other technical areas of the business. While this is still true today, the result of software eating the world has caused that scope to broaden significantly. But for mature, established businesses, IT has long been viewed as a cost center, and the mandate for an IT leader is cost minimization. This is in spite of the fact that the business has shifted away from humans, paper forms, and telephones to automation and software-based solutions. IT has always existed to support business operations, first by managing the technology the business depended on, now by building it. The only real change was IT transforming from a servant of the business to a partner of it.

Consequently, there are two key directives for a traditional IT organization: carry out the orders of the business and minimize cost. These goals inherently lead to a project mindset that is output- and task-oriented. Thus, IT has always been tactical and execution-minded in nature.

A Spotter’s Guide to Project-Minded IT

There are three ways to identify a project-minded IT organization. First, if both software engineers and more traditional IT roles like hardware support or help desk report up to a CIO, it’s likely a project-minded organization. In this case, it’s all just lumped into one group called “IT.”

This contrasts with product-minded companies which place IT responsibilities under a CIO, whose directive is still cost minimization, and product development responsibilities under a CTO and/or CPO (Chief Product Officer), whose directive is strategic investment. There are two distinct groups, IT and Product Development or R&D. It’s more common to see CTOs or CPOs at newer, technology-first companies than it is at mature, established businesses since this requires a major realignment. This alignment, however, is why we see many of the execution issues at companies attempting to “digitally transform” themselves.

Second, if there is a clear separation between IT or development and the business, there’s a good chance it’s a project-minded organization. This might be signaled by business partners, business analysts, or product owners who provide teams with implementation requirements and act as a backlog administrator. Developers might not have a good understanding of who their customers are or they view the business partner as the customer. This can also be signaled by frequently changing priorities, an ever-growing backlog of tasks, or unaddressed tech debt piling up. The team is typically not cross-functional, consisting only of developers and a business partner. Marty Cagan refers to these as delivery teams, and they are purely output-driven.

Alternatively, the team may be cross-functional with some form of designer (often oriented more towards UI than UX) and product manager, but it’s still governed by outputs. The product manager’s role is closer to that of a project manager armed with a product roadmap, and the closest thing developers have to product discovery is design and usability testing. Cagan refers to these as feature teams. Both delivery and feature teams exist to serve the business. These are the teams you’ll find at most companies building software.

At product-minded companies, teams are cross-functional with designers, UX, engineers, and product, and they are measured by outcomes, not outputs. This focus on outcomes means that the team is empowered to figure out the best way to solve the problems they’ve been asked to solve rather than being fed a list of features to build. These teams have an intimate understanding of their customers and interact with them regularly to perform product discovery and validate solutions. These are product teams in the truest sense but also quite rare.

The last way to spot a project-minded organization might be the most obvious. If the roadmap has a clear end point, it’s a project. Here, an IT organization treats building a software solution the same way it treats installing a new phone system. When the project is completed, teams or resources are reallocated to new projects and one of two things happen: it’s either dumped on another team to maintain and extend or no one sticks around to support it. The finished project languishes or former developers are told to context switch to it reactively and at the whims of the business. Engineers are treated as interchangeable and teams are not particularly durable or mission-driven but rather task-driven.

Product-minded companies instead embrace the virtues of minimum viable product, shipping incremental value, validating ideas, and iteration. The product manager provides a vision that unites the team in a common mission. Products are not “completed,” rather they grow and evolve. There is an emphasis on business outcomes over task outputs. Managers understand that teams are composed of people with diverse skills who are not easily fungible but who might be better suited to different phases of a product’s lifecycle. Members of a team might shift focus to other areas and priorities over time, but always in support of the team’s mission.

The Philosophical Dilemma of the Stoplight

A tactics-first mindset results in a propensity to treat software development like an assembly line. We can see this with the recent adoption of ideas from the Toyota Production System and lean manufacturing as it’s applied to software development. This emphasis on tactics causes managers to view product development as an optimization problem—if we just optimize the right set of tactics and practices, we can significantly improve throughput and quality at scale. This has led to the rise in packaged frameworks and processes like SAFe, LeSS, DAD, and Nexus as well as tactics like agile, pair programming, and test-driven development at large organizations.

The assembly-line mindset aims to take developers of arbitrary skill and background, run them through a prescribed process, and get high-quality, high-output results on the other end. I’ve never seen this deliver the desired outcomes in practice, at least not to the degree most leaders hope.

On the surface, mass production and software development share a lot of similarities. Both require quality standards, collaboration between groups of specialized workers, and repeatability. However, the reality is they are quite different from each other. A manufacturing assembly line is optimized to produce the exact same product over and over again, efficiently and reliably. Software products, especially Software as a Service, are heterogeneous. While we seek a process that produces consistent results, each product and situation is unique. Too prescriptive, and we end up with a rigid process that yields poor results and low-throughput. Too unstructured, and we end up with inconsistent and unreliable output.

Our Head of Client Experience Mike Taylor refers to this as the Stoplight Problem. To demonstrate, ask a roomful of people what to do at each phase of a stoplight. On green, everyone says “Go.” On red, “Stop.” And on yellow? The answers vary—even more so with the introduction of flashing yellow lights. How close are we to the light? How fast are we traveling? Are the roads icy? What are the cars in front or behind us doing? What happens at a yellow light is entirely context-dependent and situational. It comes down to making informed choices in the moment without an authoritative, black-and-white determination.

Execution and delivery issues invariably come down to one thing: the yellow light. The green and red lights are binary indicators. There are clear right and wrong actions to take. These are things that can be taught and learned—where tactics matter—but the yellow light comes down to making good decisions. This is something organizations struggle with at scale. How do you trust your teams to make good decisions? As a result, they end up making those decisions top-down in a command-and-control or assembly-line fashion. This is how organizations end up with delivery and feature teams. What’s needed is a sort of meta process or process for encouraging good decision making.

Empowered Product Teams

The emphasis on tactics isn’t limited to traditional project-minded IT organizations. Tactics are more visible and measurable. To a manager, tactics feel like work is happening, but they are rarely the difference maker for a company.

To illustrate, imagine handing out a bunch of axes to a group of people and telling them to go collect some wood. You might even teach them the proper technique for chopping down a tree. What happens next? Chaos. Confusion. A general sense of wandering in the woods. What kind of timber do we need? How much? What is it used for? How do we move it? Watching an army of people swinging axes is going to look like a lot of work is going on, but is it work that matters? You might follow people around, directing them where to go, which trees to cut down, and where to move them, but this won’t scale very well.

Without a guiding vision, we’re left with a bunch of people wandering in the woods swinging axes. Work happens, things get done—maybe even things that matter—but it’s haphazard and inefficient. More often than not, though, we’re always two weeks from completion because there isn’t clarity on where we’re trying to be. In agile terminology, we’re iterating to nowhere.

Our response might be to micromanage or implement the assembly-line process, turning our teams into feature factories. In my experience, this creates new challenges. In the first case, by grinding throughput to a halt, and in the second case, by failing to address the Stoplight Problem. The solution is a combination of vision, strategy, and execution.

A vision is a mental image of what the future could be like. It’s a grand and idealistic state, not something that can be achieved in a short amount of time. A shared vision empowers teams to make better decisions independently.

Strategy consists of a plan with decreasing fidelity. Some organizations attempt to plan 12 to 18 months out in a very waterfall-like fashion, and unless you’re sending a rocket into space, it just doesn’t work. A strategy is really a series of goals that get progressively fuzzier the further you go out. While a vision usually isn’t directly actionable, goals are both actionable and attainable in support of the overarching vision. We can break our strategy down into sets of three-month goals, which allows us to adjust course as needed. This is important since our goals are increasingly fuzzy. The key here is that strategy and goals are not dictated to teams. There needs to be give and take and dialog. OKRs can be a good tool for facilitating this.

At Real Kinetic, we hold quarterly leadership offsites to revisit our vision and strategy, course-correct, and ensure we have a general sense of alignment. We help our clients do the same within their product development organizations. The challenge with strategy is it looks like talking, while tactics look like working, even if it’s work that doesn’t truly move the needle. This is a cognitive bias leaders and managers should be aware of because it can trap us into focusing on tactics that aren’t framed by a clear vision and strategy.

Execution is all about hitting the goals we lay out in our strategy. This is where tactics come into play, but rather than providing teams with a list of features to implement or tasks to perform, we empower them to make good decisions. This is made possible by our guiding vision and cross-functional, mission-driven product teams. Our product manager is figuring out what lies ahead and helping plan the best course of action for realizing our vision. They are looking at value and business viability risks for the product. Our designer is looking at usability risks, and our tech lead is looking at feasibility, making estimations, and contributing to the strategy in order to avoid potential obstacles. You’ll notice that nowhere have we mentioned agile or scrum because these are specific tactics for managing execution. Together, the team is determining execution and discovering a solution that moves the business towards the ideal state set forth by its leadership.

Becoming a Technology Product Company

The struggle with digital transformation is it doesn’t get at the heart of the issue. It’s a tactical response to a tangible, yet ultimately inconsequential, part of the problem. The problem is not due to technology or innovation or particular tactics, it’s due to organizational alignment and execution deficiencies. Unfortunately, the former is more visible and more easily acted on than the latter.

The transformation that organizations are actually after is becoming a technology product company. This requires empowered product teams in combination with vision, strategy, and execution. Most companies focus on the execution because it’s easier, but it’s not sufficient. Empowered product teams require a shared vision that enables them to make good decisions without the need for an overly regimented or top-down process. This is the only effective way I’ve seen software companies scale throughput and quality. Don’t let your organization think it’s building a boulevard when it’s actually planting perennials next to potholes.

Planting Perennials Next to Potholes

Silos, bikesheds, and focusing on what matters

If you’ve ever flown into Des Moines then you’ve had the privilege of driving on what might be the most decrepit major road in the metro area. An important artery, Fleur Drive is the only way to get to and from the airport, and the pavement is marginally better than that of a dirt road. Cars weave back and forth to dodge potholes and massive cracks in the asphalt as people race to catch their flights. There always appears to be some kind of construction going on somewhere along the six mile stretch of road, and yet, it never seems to actually improve. The road is also located in a major floodplain, so sometimes the city just closes it when the nearby river rises too much. It’s basically what you’d get if you agiled your way through urban planning.

Typically, you’ll see the Public Works Department planting flowers or otherwise maintaining the landscaping of the medians. It goes down to one lane when they have to water the flowers. Over the past month, they tore up and poured new concrete to replace the medians altogether, again bringing the road down to one lane in the process. The tulips look nice though.

It’s interesting because a lot of companies build software this way. They quickly pave the road by iterating their way there, ignoring nearby flood hazards or the anticipated traffic that’s going to be traversing it. They plant some flowers along the way to make it look nice and then move on to the next thing. Over time, the road deteriorates. Fleur is a main thoroughfare, so you can’t just close it and repave. The city doesn’t have the budget to repave it all at once anyway. So you patch up a few potholes and plant some new flowers.

There are a few different facets to this depending on what vantage point you look at it from. As it turns out, however, they all dovetail into the same thing. At the individual level, what you often see is bikeshedding. That is, engineers focusing time and energy on technical minutiae that, in the grand scheme of things, don’t really matter. Often it’s fixating on aesthetics and what you can see rather than function or things that truly move the needle forward in a meaningful way. Sometimes we get caught up in the details and plant flowers. When you’re up to your neck in alligators, it’s hard to remember that your initial objective was to drain the swamp. This often comes from a lack of direction for the team, and it’s the manager’s job to ensure we’re focusing on what matters.

At the team level, we start to run into siloing issues. This happens when we have different functions of the business focusing on their little parts of the world, more or less neglecting the other parts. Development focuses on development. Operations focuses on operations. Security focuses on security. What you get is gridlock, an utter inability to make progress because everyone is uncompromisingly fastened to their silo. Worse yet, what does manage to get done is a patchwork of competing goals and agendas. It’s building new medians as the roads crumble. And silos are not limited to pure business functions like development, operations, and security. There are silos within silos—Product Team X and Product Team Y, for example. Silos are recursive. They are a natural team dynamic that occurs as organizations grow in accordance with Dunbar’s number, especially at companies that rigidly specialize by function. This is why a cohesive vision is critical.

At the organization level, we see large-scale strategy problems and what I call “WIP-lash”—lots of WIP (Work In Progress), lots of shifting priorities, and lots of “high-priority” items. Priorities change at the drop of a hat or everything is a priority all of the time or the work is planned 12 months in advance and by the time we execute, the goalposts have moved. Executives make knee-jerk mandates in absolute terms to respond to the newest fire. Tech debt piles up as things are added to the never-ending priority queue (that’s at least one thing that doesn’t get equal priority as everything else!), but the infrastructure is in a constant state of ruin and the potholes don’t stop. WIP-lash is just strategic bikeshedding. This is a prioritization and planning issue through and through. We can’t close the entire road and repave it. Instead, we do it in phases. Managing tech debt works the same way. We have to pay it down periodically, but not with constant band-aids and chewing gum and not by stopping the world. We have to prioritize the work like everything else we do, and sometimes that means saying no to other things we deem important.

OKRs can be a useful way to force those difficult decisions and provide teams a shared vision. Specifically, they are the strategy to balance out the iterative tactics of agile. If you don’t have some kind of mile markers you’re working towards, you’re just iterating your way to nowhere. OKRs are not intended to be a waterfall approach, they are about providing strategic guidance. That doesn’t mean companies don’t screw it up though, especially when consultants get their hooks into things. They don’t need to be a large, scary, expensive process with fancy tools—just a Word document and real discussions about what needs to happen and dialogues about what is actually possible. OKRs are hard to get right though and, like anything, require iteration. A key part of good OKR processes is using them to drive discussions and negotiations up and down the organization. It surfaces conflicts and alignment issues earlier in the process. It provides line managers a mechanism to push back and force hard decisions and open a dialogue between groups. The discussions on what really matters and the negotiation about what is really possible is the major value.

“Do you want this or that? I only have resources for this.”
“Oh, I actually have engineers I can lend this quarter. Maybe that will help?”
“Sure, but we can only accomplish part of that.”
“We can make that work.”

OKRs are a vehicle for strategic discussions, not tactical status updates, task lists, or waterfall plans. Without some sort of guiding vision that you’re working towards, you’re just doing stuff. That might look and feel productive but only on the surface. It must be a negotiation if you want results and not just activity.

It really comes down to prioritization and alignment. At the individual level, we have tactical bikeshedding—focusing on items that are largely inconsequential. This is a prioritization problem. It falls on managers to keep teams focused, but it also flows from broader organizational issues. It’s particularly insidious in companies that separate product management (“the business”) from product development (“engineering”). At the organization level, we have strategic bikeshedding—being unable to make hard decisions and focus in on what matters to the business right now, resulting in WIP-lash. This is also a prioritization problem, and it leads to the tactical bikeshedding mentioned earlier. In between, at the team level, we have siloing. This causes all sorts of issues ranging from gridlock and broken customer experiences to duplication of effort. It’s an alignment problem.

There is not a simple, quick solution to these problems, but it starts at the top. If management is not in alignment and unable to prioritize what matters, no one else will. Work will happen, and to a passerby that can look reassuring, but is it work that matters? OKRs are not a silver bullet, and they are difficult to do and take time to get right. But when executed well, they can be a powerful lens to focus on what matters and provide a shared vision. As Intel co-founder and former CEO Andy Grove said, the most powerful tool of all is the word “no.”

Operations in the World of Developer Enablement

NewOps is not a replacement for DevOps, it’s an evolution of it by looking at Operations through the lens of product. It’s what I’ve come to call “Developer Enablement” because the goal is to shift the focus of Ops teams from being masters of production to enablers of production. Through Developer Enablement, teams are enabled—and tasked with the responsibility—to control their own destiny. This extends far beyond just the responsibility of building products. It includes how we build, test, secure, deploy, monitor, and operate systems.

For some, this might come naturally. Many startups don’t have the privilege of siloing up their organizations (although you’d be surprised!). For others, this can be a major shift in how we build software. Especially in large, established organizations with more specialized roles, responsibilities can be so siloed people aren’t even aware they’re happening. Basic “ilities” like scalability, reliability, and even security become someone else’s responsibility. “Good Operations” means no one even knows you’re there, unless something goes wrong.

So when this is turned on its ear, and these responsibilities are placed on the dev team’s shoulders, how do they adapt? In many cases, teams are eager to take on these new responsibilities but also blissfully unaware of what that actually entails. DBAs are a good example of this. Often a staple of enterprise IT Ops, DBAs are tasked with—among other things—installing and patching DBMSs, performing backups, managing HA and DR strategies, balancing database workloads, managing resources, tuning performance, configuring security settings, and monitoring systems. Many of these responsibilities are invisible to developers.

With cloud and Developer Enablement, this can change in profound ways. However, in a typical lift-and-shift, the role of DBAs is widely unchanged. In this case, we’re just running the same stuff in someone else’s data center. There are still databases to be patched, replication to be managed, backups to be made, and so on. But pure lift-and-shifts, at least as an end goal, are largely a misstep. You throw away all that institutional memory—the knowledge and experience you have managing your own data center—for more expensive compute with which you have less experience administering. Things change when we start to rely on managed cloud services. We no longer run our own databases on VMs but instead rely on cloud-managed ones. This is where things become much more grey—but also much more interesting.

Developer Enablement in the Cloud

First, a quick aside. There are two different concepts we’re talking about here: cloud and Developer Enablement (DevOps for brevity). These are two distinct but related concepts. We can “do” DevOps on-prem, just as we can in the cloud. Likewise, we can also do traditional Operations in the cloud, just as we can on-prem. One of the benefits of cloud is it allows us to focus more investment on business-differentiating things, but it also makes implementing DevOps easier for two reasons. First, the cloud provider takes on more operational responsibilities (the stuff that supports—but doesn’t directly contribute to—business value). Second, it provides a lower barrier to self-service infrastructure. This means developers can, of their own accord, provision and manage supporting infrastructure like databases, caches, queues, and other things without a go-between or the customary “throw-it-over-the-wall” approach. This is a key part of Developer Enablement.

In the world of Developer Enablement in the cloud, what is the role of a DBA, or any other Ops person for that matter? When you start to map who is accountable for what, you quickly realize there is far too much nuance to cleanly map responsibilities. Which cloud provider are we talking about? Within that cloud provider, which database offering? Proprietary NoSQL databases like Google’s Cloud Datastore? Relational databases like Amazon’s RDS? Globally-distributed databases like Spanner? How we handle things like HA and DR vary drastically depending on the service and service provider. In some cases, the vendor is entirely responsible, e.g. because the database has built-in replication. In other cases, the customer. Sometimes it’s a combination of both, such as a database that has automated backups which must first be enabled. It’s not as cut and dry as it used to be.

As we push more responsibility onto developers, how do we ensure they are actually tackling all of those responsibilities, especially the ones they might not even know about? How do we implement DevOps responsibly?

The goal of Developer Enablement is not to enable developers by giving them total control and free rein. Instead, it’s to empower them in a way that is “safe” for the business. People often misconstrue DevOps and automation as things that reduce lead times and increase deployment frequencies by simply pulling security out of the process. This is categorically not the purpose of DevOps. In fact, the intention is to improve security by integrating it more deeply and earlier into the process in a more reliable and repeatable way, i.e. “shift left.” Developer Enablement is about providing the tools, automation, services, and standards teams need to do just this.

So when we say we want to implement DevOps and Developer Enablement, we’re not saying we want to hand developers the keys to production with a pat on the back. We’re saying we want to pave a path to production which allows developers to release software in a way that is safe and secure with greater autonomy—because autonomy enables building more reliable software faster. In this world, Operations teams become increasingly Developer Enablement teams because there is simply less stuff to operate. It becomes more about supporting development teams and organizing around products than acting purely as a gatekeeper or service provider. It’s pretty amazing how things start to improve when you align yourself this way.

Responsibilities of Developer Enablement

Those Operations teams still have extremely valuable skill sets however. It’s just that they start to act more in an advisory role than the assembly-line-worker role converting Jira tickets into outputs. For instance, DBAs have deep expertise on the intricacies and operations of various database systems, but when Amazon is now responsible for installing the database, patching it, scaling it, monitoring it, performing backups, managing replication and failovers, and handling encryption and security, what do the DBAs do? They become domain experts and developer advocates. They make sure teams aren’t shooting themselves—or the company—in the foot and provide domain expertise and tooling in a supporting role. When a developer complains about a slow query, they are the ones who can help them identify, understand, and fix the problem. “It’s doing a full-table scan since you’re missing an index,” or “You have a hot partition because you’re using a timestamp as the partition key. Try using a more uniform ID to distribute workloads evenly.” These folks can often help developers better structure their data to improve application performance and scalability.

In addition to this supporting role, these Developer Enablement teams also help ensure dev teams are thinking about all the things they need to be considering. In the case of data, how is encryption handled? HA? DR? Data migrations? Rollbacks? Not that all of these things need to be handled by the teams themselves—again, often the cloud provider has it covered—but simply ensuring that they have been considered and can be spoken to is important. It’s vital to start this conversation early in the development process.

The Three Phases of Development

There are basically three phases of development to consider. There’s the “playground” phase, which is when teams are essentially exploring different technologies. At this stage, there can be little-to-no oversight outside of controlling cloud spend (which is important for when your intern accidentally starts a task bomb before leaving for the weekend). Teams are free to try out new ideas without worrying about production. Often this work happens in a separate “experimentation” cloud project.

Next, there’s the “green-light” phase. The thing being built is going to production, it’s part of the company’s strategic plan, people are talking about it, etc. At this point, we start an ongoing dialogue with the team and provide them with a list of the key things to be thinking about. This should not be a 10-page document. It should be a one-page document hitting the main areas. An example portion of this might look like the following:

  • How do you plan to implement HA?
  • What classifications of data will this system handle and how do you plan to secure that data in transit and at rest?
  • How much traffic do you expect the system to handle and how will you scale it?
  • How will the system handle authentication and authorization?
  • What are the integration points?
  • Who will support the system in production?
  • What is the CI/CD story for the system?
  • What is the testing strategy?

Depending on your company’s culture, this can sometimes be seen as an affront or threat to teams if they’re used to Ops or InfoSec groups gatekeeping. That is not the goal as it’s intended to be in an advisory capacity. This ends up having a couple benefits. First, it gets teams thinking about and planning for key operational items, and second, it uncovers any major gaps early in the process. The number of times I’ve heard someone ask, “What’s HA?” after reading this list is non-zero. The purpose of this isn’t to shame anyone, just to provide a way to start critical discussions between the team and Developer Enablement groups.

Finally, there’s the “ready-for-production” phase. The team is ready to ship what they’ve been building. This is where things get real. Typically, there are a few things that should happen here. When launching a new service or product, there should be a comprehensive review of the system. The team will sit down with a group of their peers, architects, and security engineers and walk them through the system. People hate the dreaded architecture review, so we call it a product technical walkthrough instead.

Operational Readiness and Change Management

About a month or so prior to the walkthrough, the team should be working through an “operational-readiness checklist” which is used to guide the walkthrough. This checklist is much more detailed than the previous one, enumerating items like what the deploy process consists of, configuration management, API versioning, incident-response procedures, system observability, etc. The checklist we commonly use with clients at Real Kinetic is about seven pages long and covers 10 areas: Deployment, Testing, Reliability/Failover, Architecture, Costs, Security, CI/CD, Infrastructure, Capacity/Performance Estimates, and Operations and Support. This checklist is used to probe different areas. If certain areas feel a little weak, this can lead to deeper discussions depending on the importance or severity. If a system is particularly critical to the business or high-risk, this process can veto a release. Having a sign-off process like this makes some people nervous, but it’s important to point out that this should only apply to new launches. It is not a general change-management process. It’s really about helping teams learn about running systems in production and understanding what that takes.

In addition to the product technical walkthrough, we also recommend doing a security assessment for new services. This usually encompasses a vulnerability and threat assessment, risk assessment, pen testing, the whole nine yards. I usually also like to see some sort of load profiling done on the service before putting it in production (though load and chaos testing should ideally be part of the normal development process, not saved for the very end).

When it comes to infrastructure, there’s also the question of how to manage changes. This is where infrastructure as code (IaC) becomes hugely important as it not only provides a way to automate infrastructure changes, but also a means to review those changes. We can treat infrastructure changes in the same way we treat application changes—storing them in source control, doing code reviews on them, running them through static analysis tools, and so forth. Infrastructure changes, like all changes, should go through a code review process. It cannot be overstated how essential code reviews are and how much they benefit your organization. And once again, this is where Developer Enablement comes into play. I recommend IaC changes be reviewed by a Developer Enablement team member. This provides a touchpoint where they can provide domain expertise and ensure changes are within acceptable parameters. If a developer is requesting a change which falls outside those parameters, such as a database instance with 1TB of RAM for example, it requires a conversation and sign-off process.

Conclusion

With Developer Enablement, what used to be Operations becomes primarily a product and advisory team. “Product” in the sense of providing systems and tools that help developers take on more responsibility, from day-to-day development to operations and support. “Advisory” in the sense of offering domain expertise and guidance. Through this approach, we get better alignment by giving engineers end-to-end ownership from development to on-call and improve efficiency by reducing handoffs. This also lets us scale more effectively. Through products and reduced hand-offs, a Developer Enablement group can empower far more engineers than any conventional Ops team could.
