Zero-Downtime Deployments
Progressive delivery with automated rollback. Friday afternoons stop being scary.
- Deploys at noon Tuesday instead of 11pm Friday
- Automated rollback on SLO regression
- Deploy frequency up, change failure rate down
Deploys are scary because they're high-stakes one-shot events. Replace them with progressive, observable, automatically-rolled-back changes and they become non-events.
What changes
Argo Rollouts or Flagger for canary / blue-green strategies, traffic shifted by percentage with health checks at each step, automated rollback when SLOs degrade, feature flags decoupling deploy from release. Suddenly the engineer who shipped the bug isn't in a Slack war room — the platform rolled it back at 1% traffic.
Outcomes
Multi-deploy-a-day cadence even on critical services, SLO-driven rollback within 60 seconds of regression, and a deploy culture where small frequent changes replace heroic releases.
