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 — Developer Productivity

Covers flow efficiency, lead time, deployment frequency, and time to first deployment as developer productivity signals.

2 — DORA Metrics

Covers the four DORA metrics, their known limitations, and how to read them from a platform team's perspective.

3 — SPACE Framework

Covers the SPACE framework's five dimensions — satisfaction, performance, activity, communication, and efficiency.

1 — The Evolution of Infrastructure Engineering

Traces infrastructure engineering from physical servers through virtualization, the rise of cloud computing, and infrastructure automation to the point where platform engineering became necessary.
