3 — DevOps vs SRE vs Platform Engineering

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.

Site Reliability Engineering: From Foundations to Internet-Scale Systems

The complete 184-chapter, 15-part Site Reliability Engineering curriculum — from Linux internals and distributed-systems theory through reliability engineering, observability, incident response, platform engineering, and Staff/Principal-level MAANG interview preparation, ordered the way SRE expertise actually develops rather than as a topic index.

1 — What is Site Reliability Engineering?

What SRE actually is when you strip away the Google mythology — applying software engineering discipline to operations problems, with error budgets as the mechanism that makes reliability a measurable, negotiable trade-off instead of an absolute.

2 — History of SRE (Google and Beyond)

How Ben Treynor's 2003 Google team turned an operations headcount problem into a discipline, and how the practice diverged as Amazon, Microsoft, Meta, and Netflix each adapted it to their own org shape.

4 — Reliability as an Engineering Discipline

Why reliability has to be designed and budgeted like a feature, not bolted on afterward as an operations concern.

5 — Service Lifecycle

The stages a service moves through from design to deprecation, and the reliability gate that should exist at every transition.
