If you use Linux in development or operations and need a structured approach to help you dive deeper, this book is for you. Author Michael Hausenblas also provides tips and tricks for improving your workflow with this open source operating system. Whether you're a developer, software architect, or site reliability engineer, this hands-on guide focuses on ways to use Linux for your everyday needs, from development to office-related tasks. Along the way, you'll gain hands-on experience with modern Linux terminals and shells, and learn how to manage your workloads. You'll understand how to run Linux applications by using containers, systemd, modern filesystems, and immutable distros such as Flatcar and Bottlerocket. Use Linux as a modern work environment, rather than just from an admin perspective Learn critical components such as the Linux kernel, terminal multiplexer, human-friendly shells, and portable shell scripting Become familiar with access control, from file permissions to capabilities, and understand the role of filesystems as a fundamental building block Learn about application dependency management and containers Gain hands-on experience with the Linux networking stack and tooling, including DNS Apply modern operating system observability to manage your workloads Become familiar with interprocess communication, virtual machines, and selected security topics

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 systemsUnderstand observability signals, including their costs and benefitsApply good practices around instrumentation and signal collectionDeliver dashboarding, alerting, and SLOs/SLIs at scaleChoose the correct signal types for given roles or tasksPick the right observability tool for any given functionCommunicate 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.
