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 — 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.

2 — From System Administration to Platform Engineering

Contrasts traditional system administration with the DevOps revolution, cloud-native transformation, and the modern platform team model that emerged from both.

3 — DevOps, SRE, and Platform Engineering

Separates what DevOps, SRE, and Platform Engineering each solve, where their responsibilities and boundaries lie, and how the three disciplines work together in practice.

4 — Why Platform Engineering Exists

Grounds platform engineering's existence in scaling engineering organizations, reducing developer cognitive load, increasing velocity, and balancing standardization against flexibility.
