Generate actionable insights about your cloud native systems. This book teaches you how to set up an observability system that learns from a cloud application’s signals, logging, and monitoring using free and open source tools.

In Cloud Observability in Action you will learn 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 containerized applications are made up 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 the 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 optimized in the future. Best of all, observability allows you to easily automate your error handling with machine users applying fixes without any human help.

Observability is the capability to continuously generate and discover actionable insights based on signals from the (cloud native) system under observation, with the goal to influence the system. The way we approach the topic is a Return-on-Investment driven one: we look at costs and benefits, from the sources to telemetry including agents to the signal destinations (back-ends such as time series datastores as well as frontends like Grafana). Throughout the book, I’m using open source tooling including but not limited to OpenTelemetry (collector), Prometheus, Loki, Jaeger, and Grafana to demonstrate the different concepts and enable you to experiment with them, without any costs, other than your time.

about the book
Cloud Observability in Action teaches you to apply observability practices to cloud-based serverless and Kubernetes environments. In this one-of-a-kind guide, author Michael Hausenblas shares insights from his extensive experience building, monitoring, and improving cloud native systems.

You’ll use open source tools like Prometheus and Grafana to build your own observability system without having to rely on proprietary software. Learn how to use telemetry and destinations to continuously generate and discover insights from different signals, including logs, metrics, traces, and profiles. Throughout, use cases and rigorous cost-benefit analysis make sure you’re getting a real return on your investment in observability.

about the reader
