    Getting big wins with small teams on tight deadlines

    Part of what we do at Real Kinetic is give companies confidence to ship software in the cloud. Many of our clients are large organizations that have been around for a long time but who don’t always have much experience when it comes to cloud. Others are startups and mid-sized companies who may have some experience, but might just want another set of eyes or are looking to mature some of their practices. Whatever the case, one of the things we frequently talk to our clients about is the value of both serverless and managed services. We have found that these are critical to getting big wins with small teams on tight deadlines in the cloud. Serverless in particular has been key to helping clients get some big wins in ways others didn’t think possible.

    Microservice Observability, Part 2: Evolutionary Patterns for Solving Observability Problems

    In part one of this series, I described the difference between monitoring and observability and why the latter starts to become more important when dealing with microservices. Next, we’ll discuss some strategies and patterns for implementing better observability. Specifically, we’ll look at the idea of an observability pipeline and how we can start to iteratively improve observability in our systems. To recap, observability can be described simply as the ability to ask questions of your systems without knowing those questions in advance. This requires capturing a variety of signals such as logs, metrics, and traces as well as tools for interpreting those signals like log analysis, SIEM, data warehouses, and time-series databases. A number of challenges surface as a result of this. Clint Sharp does a great job discussing the key problems, which I’ll summarize below along with some of my own observations.

    Authenticating Stackdriver Uptime Checks for Identity-Aware Proxy

    Google Stackdriver provides a set of tools for monitoring and managing services running in GCP, AWS, or on-prem infrastructure. One feature Stackdriver has is “uptime checks,” which enable you to verify the availability of your service and track response latencies over time from up to six different geographic locations around the world. While Stackdriver uptime checks are not as feature-rich as other similar products such as Pingdom, they are also completely free. For GCP users, this provides a great starting point for quickly setting up health checks and alerting for your applications.

    API Authentication with GCP Identity-Aware Proxy

    Cloud Identity-Aware Proxy (Cloud IAP) is a free service which can be used to implement authentication and authorization for applications running in Google Cloud Platform (GCP). This includes Google App Engine applications as well as workloads running on Compute Engine (GCE) VMs and Google Kubernetes Engine (GKE) by way of Google Cloud Load Balancers. When enabled, IAP requires users accessing a web application to login using their Google account and ensure they have the appropriate role to access the resource. This can be used to provide secure access to web applications without the need for a VPN. This is part of what Google now calls BeyondCorp, which is an enterprise security model designed to enable employees to work from untrusted networks without a VPN. At Real Kinetic, we frequently bump into companies practicing Death-Star security, which is basically relying on a hard outer shell to protect a soft, gooey interior. It’s simple and easy to administer, but it’s also vulnerable. That’s why we always approach security from a perspective of defense in depth.

    The Observability Pipeline

    The rise of cloud and containers has led to systems that are much more distributed and dynamic in nature. Highly elastic microservice and serverless architectures mean containers spin up on demand and scale to zero when that demand goes away. In this world, servers are very much cattle, not pets. This shift has exposed deficiencies in some of the tools and practices we used in the world of servers-as-pets. It has also led to new tools and services created to help us support our systems.
