Improving Reliability w/ Error Budgets & SRE
summary
Argues that reliability improves only when teams use concrete metrics and automation: define SLIs/SLOs/SLAs, track a service level objective (example: 95th percentile latency <300ms in a 5‑minute window), and enforce an error budget so product and ops share decisions. Recommends progressive rollouts, canaries and automated rollback (70% of outages trace to changes), blameless postmortems, capacity planning and hiring engineers who automate; start by applying this to one service.
