Don’t fly blind. Observability gives you actionable insights into your cloud native systems—from pinpointing errors, to increasing developer productivity, to tracking compliance. Observability is the difference between an error message and an error explanation with a recipe how to resolve the error! You know exactly which service is affected, who’s responsible for its repair, and even how it can be optimized in the future. Cloud Observability in Action teaches you how to set up an observability system that learns from a cloud application’s signals, logging, and monitoring, all using free and open source tools. The book focuses primarily on developers, DevOpssite reliability engineers (SREs), who are working with cloud-native applications. It is meant for anyone interested in running cloud-native applications, be that in Kubernetes or using function-as-a-service offerings, such as AWS Lambda.
