Chapter 9: Monitoring, Logging, and Observability
In previous chapters, we learned about application deployment best practices on Kubernetes to modernize our architecture. We learned how Kubernetes creates an abstraction layer on top of a group of container hosts that makes it easier to deploy applications and, at the same time, changes development teams' responsibilities compared to traditional monolithic applications. Adopting microservice architectures requires implementing new observability practices to efficiently monitor the layers introduced by the Kubernetes platform. Whether you plan to expand your existing monitoring stack to include Kubernetes or are looking for a complete cloud-native solution, it is essential to know the critical metrics to monitor and create a strategy to enhance observability to troubleshoot and take effective action when needed.
In this chapter, we will discuss the vital infrastructure components and Kubernetes object metrics. We will understand...
