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 — Identity and Access Management

IAM foundations for a platform: how identity, group membership, and service accounts map onto catalog and provisioning permissions.

2 — Platform Security

Security responsibilities that belong to the platform itself, distinct from the security posture of the services running on top of it.

4 — Platform Guardrails

Guardrails as the difference between a self-service platform and an ungoverned free-for-all: constraints that don't require a human in the loop.

5 — Compliance by Default

Building compliance requirements into golden paths and templates so services are compliant by construction, not by later audit.
