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 — API-Driven Platforms

Why every platform capability should be reachable by API first, with the portal UI as a client of that API rather than the source of truth.

3 — Workflow Engines

Workflow engines for orchestrating multi-step platform operations (provision, configure, register, notify) with retries and visibility.

4 — Platform Orchestration

Orchestration patterns that coordinate multiple platform capabilities, catalog, templates, provisioning, access, into a single self-service action.

5 — Infrastructure Automation

Infrastructure automation, Terraform/Crossplane-style provisioning, as the execution layer behind self-service infrastructure requests.
