Production deployment workflows and CI/CD best practices. Setting up CI/CD pipelines Dockerizing an application Planning deployment strategy (blue-green, canary, rolling) Implementing health checks and readiness probes Preparing for a production release Configuring environment-specific settings Replace instances gradually — old and new versions run simultaneously during rollout. Pros: Zero downtime, gradual rollout Cons: Two versions run simultaneously — requires backward-compatible changes Use when: Standard deployments, backward-compatible changes Run two identical environments. Switch traffic atomically. Pros: Instant rollback (switch back to blue), clean cutover Cons: Requires 2x infrastructure during deployment Use when: Critical services, zero-tolerance for issues Route a small percentage of traffic to the new version first. Pros: Catches issues with real traffic before full rollout Cons: Requires traffic splitting infrastructure, monitoring Use when: High-traffic services, risky changes, feature flags [ ] Previous image/artifact is available and tagged [ ] Database migrations are backward-compatible (no destructive changes) [ ] Feature flags can disable new features without
