Internal Developer Platforms

A book-shaped table of contents for Internal Developer Platforms: IDP fundamentals, architecture, self-service, golden paths, software catalogs, Backstage, templates, platform APIs and automation, developer experience, governance, operations, success metrics, anti-patterns, enterprise scale, and MAANG interview preparation — cross-linking existing platform-engineering-fundamentals/sre/observability notes instead of duplicating them.

1 — Multi-Team Platforms

Platform design considerations once dozens of independent teams, not one pilot team, depend on the same golden paths.

2 — Multi-Cloud IDPs

IDP design for organizations spanning multiple cloud providers, where the catalog and templates must abstract over provider differences.

3 — Multi-Region Platforms

Multi-region platform design: where the control plane lives relative to the regions it provisions into.

4 — Domain-Oriented Platforms

Domain-oriented platform structuring, where catalog ownership and golden paths are organized around business domains rather than one flat namespace.
