Platform Engineering Fundamentals

A book-shaped table of contents for platform engineering fundamentals: evolution and organizational foundations, platform-as-a-product thinking, core principles (self-service, golden paths, automation, APIs), design principles, the platform lifecycle, DORA/SPACE metrics, anti-patterns, enterprise governance, and MAANG interview prep — cross-linking existing sre/patterns/observability/projects notes instead of duplicating them.

1 — Abstraction

How abstraction hides complexity behind platform interfaces, and the layers of abstraction a platform typically exposes.

2 — Composability

Covers modular platform design, reusable building blocks, and composable services as a platform design principle.

3 — Scalability

Covers organizational and technical scalability, and how a platform is expected to grow with the organization it serves.

4 — Reliability by Design

Covers designing for failure, platform resilience, and the reliability principles a platform bakes in by default.
