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 — Adoption Metrics

Adoption metrics, active users, service coverage, template usage, self-service rate, that show whether the platform is actually being used, not just built.

2 — Productivity Metrics

Productivity metrics, time to first deployment, lead time, developer wait time, deployment velocity, the platform is ultimately accountable for moving.

3 — Platform Reliability Metrics

Reliability metrics for the platform's own APIs and workflows: availability, latency, workflow success rate, provisioning success.

1 — The Rise of Internal Developer Platforms

Traces why IDPs emerged from the developer productivity crisis and clarifies how the term relates to, and differs from, platform engineering more broadly.
