Platform Engineering: Building and Operating Internal Developer Platforms is a practical guide for anyone involved in creating, evolving, or running a modern software platform within an organization.

Internal Developer Platforms (IDPs) are transforming how software is built, deployed, and maintained. They empower development teams to move faster, reduce operational friction, and focus on delivering value while maintaining governance, security, and reliability. This book offers a comprehensive look at the principles, practices, and organizational strategies that make these platforms successful.

From understanding developer experience challenges to designing cloud-native foundations, managing accounts and permissions, and creating self-service CI/CD and deployment environments, this book provides actionable insights drawn from years of hands-on experience. It also explores platform adoption, team operating models, automation, and the continuous evolution of platforms in response to real world user needs.

Whether you are a platform engineer, an architect, a team lead, or a technology leader, this book equips you with the knowledge to design platforms that scale, empower developers, and create measurable business value. Learn how to build platforms that are not just technology stacks, but living ecosystems that grow with your organization.
