1 — Continuous Integration

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.

10 — Supply Chain Security

SBOMs, artifact signing, and provenance attestation — verifying what's actually being deployed is what was actually built, not something injected in between.

2 — Continuous Delivery

Keeping every merged change in a deployable state, which is the precondition every other release-engineering practice in this Part builds on.

3 — Deployment Strategies

The spectrum from all-at-once to fully progressive rollout, and the blast-radius-vs-speed trade-off each point on that spectrum makes.

4 — Blue-Green Deployments

Running two full production environments and switching traffic between them atomically — instant rollback, at the cost of running double the infrastructure.
