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 — Designing Planet-Scale Systems

What changes architecturally once a system has to serve every region on earth — the assumptions that hold at one datacenter's scale and break at planet scale.

2 — Global Traffic Management

Routing users to the right region by latency, health, and capacity simultaneously, and the DNS- and anycast-level mechanics that make global failover fast.

4 — Multi-Cloud Reliability

The real cost — not just financial — of running reliably across more than one cloud provider, and where multi-cloud actually reduces blast radius versus just adding complexity.

5 — Active-Active Systems

Serving live traffic from more than one region simultaneously, and the conflict-resolution problem that active-active pushes onto every stateful write.
