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 — Introduction to Backstage

Introduces Backstage's architecture, core concepts, and plugin ecosystem as the most widely adopted open-source IDP foundation.

3 — Backstage Scaffolder

Backstage's Scaffolder plugin as the software-template execution engine: how a template becomes a running service.

4 — Backstage TechDocs

TechDocs as Backstage's docs-as-code layer: how documentation stays attached to its owning entity in the catalog.

5 — Backstage Plugins

Surveys the Backstage plugin ecosystem, Kubernetes, GitHub, Argo CD, Grafana, PagerDuty, Jenkins, and where a custom plugin becomes necessary.
