SLOs & alerting

  • Google SRE Book / Workbook — SLIs/SLOs/error budgets; Alerting on SLOs (multi-window, multi-burn-rate). The canon. https://sre.google/workbook/alerting-on-slos/
  • Implementing Service Level Objectives (Alex Hidalgo) — the practical SLO playbook.
  • Error-budget policy examples (how budget exhaustion changes behavior).

Stability patterns

  • Michael Nygard, Release It! — circuit breakers, bulkheads, timeouts, steady state, fail fast (pairs with gw-06).
  • Marc Brooker — retries, jitter, metastable failures.
  • Netflix Hystrix (archived) / resilience4j — bulkhead + breaker impls.

Observability (the SLIs)

  • gw-11 (RED/USE, histograms, tracing) — what SLOs are computed from.
  • Brendan Gregg — USE method; the four golden signals.
  • gw-06 (breakers/adaptive concurrency), gw-11 (the SLIs), gw-12 / pa-08 (error-budget-gated rollout), pa-01 (blast radius to contain), pa-06 (CAP/PACELC as SLO choices).
