Preface
The Infrastructure Change Management (ICM) program at Google drives migrations, deprecations, and other large-scale infrastructure changes. Case studies in this report explore how infrastructure change projects are managed at Google. From these case studies, we’ll provide insight into lessons learned from these different approaches, and provide an overview of techniques, processes, and tools that worked (or didn’t work).
