Generate actionable insights about your cloud-native systems. For developers and SREs who have worked with cloud-native applications. This book is suitable for any public cloud. In Cloud Observability in Action, you will learn how to set up an observability system that learns from a cloud application's signals, logging, and monitoring using free and open-source tools. You will learn, among others, how to: Apply observability in cloud native systems Understand observability signals, including their costs and benefits Apply good practices around instrumentation and signal collection Deliver dashboarding, alerting, and SLOs/SLIs at scale Choose the correct signal types for given roles or tasks Pick the right observability tool for any given function Communicate the benefits of observability to management Cloud-native, serverless, and containerised applications are made of hundreds of moving parts. When something goes wrong, it's not enough to just know there is a problem-you need to know where it is, what it is, and even how to fix it. Cloud Observability in Action shows you how to go beyond traditional monitoring and build observability systems that turn application telemetry into actionable insight. About the technology A well-designed observability system provides insight into bugs and performance issues in cloud-native applications. Often, observability is the difference between an error message and an explanation! You know exactly which service is affected, who's responsible for its repair, and even how it can be optimised in the future. Best of all, observability allows you to easily automate your error handling with machine users applying fixes without any human help.
