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 — Internal Developer Platform System Design

A worked IDP system-design prompt at the Staff/Principal bar: requirements, architecture, and the trade-offs an interviewer will probe.

2 — Designing Self-Service Platforms

A self-service-focused design exercise, distinct from the general IDP prompt, that probes provisioning workflows and approval boundaries specifically.

4 — Golden Path Design Exercises

Whiteboard exercises for designing a golden path from scratch for a given workload shape under interview time pressure.

5 — Platform API Design Interviews

API design interview practice specific to platform resource, infrastructure, and event APIs.
