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.

2 — Platform Reliability

Reliability engineering applied to the platform's own control plane: the platform going down blocks every team behind it, not just one service.

3 — Platform Observability

Observability requirements for the platform's own control plane and workflows, distinct from the observability the platform provides to its tenants.

4 — Platform Support Models

Support models for a platform team, from ticket queues to embedded support to fully self-service, and when each is appropriate.

5 — Incident Management

Incident management specific to platform outages, where the blast radius is every consuming team rather than a single service's users.
