🔗 20 Years of Google SRE
Title: Lessons Learned from Twenty Years of Site Reliability Engineering – Oct. 27, 2023
Google's Site Reliability Engineers (SREs) have shared eleven valuable lessons learned over twenty years of managing Google's infrastructure. These lessons include the importance of assessing mitigation risk based on the severity of an outage, testing recovery mechanisms beforehand, canary testing for changes, having a "Big Red Button" for emergencies, and using integration testing in addition to unit tests. They also highlight the significance of backup communication channels, graceful degradation for consistent user experiences, disaster resilience and recovery testing, automation of mitigations, reducing rollout intervals, and avoiding a single point of failure by maintaining a diverse infrastructure. These lessons are derived from real-world incidents and experiences, helping improve service reliability and performance.

🔗 Dealing with Orphaned Pods in Kubernetes
Title: Kubernetes And Kernel Panics – Oct. 28, 2023
The article discusses how Netflix's container platform, Titus, addresses the issue of orphaned pods in Kubernetes. These orphaned pods are problematic for batch users, and the article outlines a solution to connect the dots from kernel panics to Kubernetes and operators. It involves annotating pods with termination reasons, using netconsole to capture kernel panic data, and creating a Kubernetes controller to detect kernel panics and take appropriate actions, including annotating and deleting affected pods and nodes. This approach provides improved observability and helps in diagnosing and resolving issues related to kernel panics.
