Transform enterprise IT by adopting site reliability engineering (SRE) practices that reduce downtime, build resilience, and drive business value.

This book is a comprehensive guide designed to help site reliability engineers, DevOps teams, and platform engineers identify, address, and mitigate system weaknesses before they become significant critical failures. Authors Francesco Sbaraglia and Florian Hoeppner highlight the paradigm shift from IT as a cost center to a core business function, emphasizing the central role of developers and the need for speed and reliability. They detail the challenges of transitioning to SRE, including overcoming cultural resistance and legacy infrastructure limitations, while bringing to the forefront the importance of building resilience in systems and processes. Specific SRE capabilities like chaos engineering, observability, and toil management are explored, along with strategies for successful implementation, including building a Center of Excellence, selecting the right tools, and fostering a culture of collaboration and continuous improvement.

Looking ahead, the book examines emerging trends like Agentic AI SRE Agents, the use of generative AI (GenAI) in SRE and the future evolution of chaos engineering. You’ll learn how to embed SRE practices into your existing enterprise tech operating model and unlock tangible business outcomes: reduced downtime, increased resilience, and measurable gains in stability. Additionally, discover how GenAI can support SRE teams in planning, executing, and optimizing reliability experiments and automating toil reduction and continuous improvement efforts.

By the end of this book, you’ll know how to apply core SRE practices to strengthen reliability: establishing a chaos engineering practice led by SREs, running reliability-focused “game days,” improving observability, troubleshooting failure scenarios, and fortifying the digital resilience of your systems and teams.
