• Deployment patterns

  GitOps

  GitOps is a deployment pattern where a Git repository holds the declarative desired state of your system and an automated controller continuously reconciles the live environment to match it. Every change ships as a commit, every rollback is a `git revert`, and the repo - not a console or a one-off command - is the audit log.

• Observability

  Golden signals

  The golden signals are the four measurements Google's SRE book recommends watching on every user-facing service: latency, traffic, errors and saturation. Together they give a compact, high-signal view of health, so teams can spot regressions during a release, gate a canary promotion or trigger a rollback.
