Starting an SRE Practice From Scratch

SRE at Google scale is different from SRE at startup scale. The practices scale down; the full structure does not.

SLOs First

Define service level objectives for critical services. Error budget. Alert on burn rate.

Runbooks

Every alert has a runbook. Unbooked alerts are cleanup items.

Post-Mortems

Blameless. Action items. Tracked. Culture change more than process.

Toil Budget

Cap manual ops work at 50% of SRE time. Force automation of the rest.

Who This Is For

  • Platform and SRE teams owning reliability
  • Engineering leaders establishing DevOps culture
  • Teams shipping faster than their pipeline can safely support

Common Mistakes

  • Buying DevOps tools without changing culture
  • Treating SLOs as KPIs instead of decision tools
  • Automating what should be eliminated

Business Impact

  • Deploy frequency measured in hours, not sprints
  • Change failure rate under 5% at full velocity
  • Engineer time reclaimed from manual ops

Frequently Asked Questions

SRE vs DevOps?

Overlapping. SRE is opinionated implementation. DevOps is a broader philosophy.

Dedicated SRE team?

At scale. Before then, engineers practice SRE skills in a DevOps culture.

Google SRE book?

Read it. Adapt it. Don't copy blindly.
