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 — Why Software Catalogs Matter

Makes the case for a software catalog as the discoverability, ownership, documentation, and governance backbone of a platform.

2 — Service Catalog Design

Catalog design choices, entity types, metadata schema, ownership fields, and relationship modeling, that determine whether the catalog stays trustworthy at scale.

3 — Catalog Data Model

A concrete data model spanning services, APIs, libraries, systems, components, and resources as first-class catalog entities.

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.
