About the book
Platform Engineering has moved from a niche discipline to a business-critical function in the space of three years. Yet most of the guidance available is either too conceptual to execute on, or too tied to a specific tool or vendor to generalise.
This book was written to close that gap. Drawing on real patterns from organisations building Internal Developer Platforms at scale in 2025 and 2026, it covers everything from the strategic case for platform investment to the technical decisions that will define your platform's longevity.
Across 32 chapters and 9 parts, it covers foundations, IDP architecture, observability, security, FinOps, AI, team topologies, and production-ready reference architectures for AWS, GCP, Azure, and multi-cloud environments.
Why I wrote this
Throughout my career I have had to make real platform engineering decisions — decisions with budget, team, and organisational consequences. The resources I needed either did not exist, were too abstract, or were written for a scale and context that did not match the reality I was operating in.
This book is the resource I wished I had. It is written for practitioners who need to make decisions, not for academics who need to describe them. Every chapter is grounded in what works in production, at scale, in 2026.
