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 — Backstage Entity Reference

Quick reference for Backstage's built-in entity kinds (Component, API, System, Domain, Resource, User, Group) and their required fields.

3 — Software Catalog Schema Examples

Worked catalog schema examples for the entity types introduced in Part V, as copy-adaptable starting points.

4 — Platform API Design Patterns

A pattern catalog for platform API design: pagination, idempotency keys, async operation status, specific to provisioning-style APIs.

5 — Developer Journey Mapping Templates

Blank developer-journey mapping templates for running the exercise from Part IX with a real team.
