How does Rails handle large-scale system reliability engineering (SRE) practices?

Rails systems implement SRE practices like SLIs, SLOs, error budgets, and automated incident response.

SRE principles ensure system reliability through measurable metrics. Rails applications define SLIs (latency, error rate), SLOs (targets), and error budgets (allowed failures). Monitoring tools track compliance, and alerts trigger incident response workflows. Automation reduces manual intervention during failures. This ensures predictable reliability in production systems.
