Deployment strategies control traffic shifts, rollback speed, and release risk. Options: canary, blue‑green, rolling, feature flags, shadow, immutable, and GitOps.
Strategies trade production risk for setup cost. They pair with Argo Rollouts, Kayenta, ArgoCD/Flux, service meshes, and flag platforms.
Pipelines must automate schema migrations, observability, and rollback.
Teams converge on progressive delivery - combining GitOps, automated canaries (Argo Rollouts/Kayenta), and feature flags. Outcome: Fewer surprises. Fewer 2 a.m. all‑hands.
