Zero-downtime Deployment Strategies (...) [ENG]
summary
Live demos show concrete zero‑downtime patterns implemented on Kubernetes with mentions of Traefik and Istio, including how to write readiness and liveness probes and handle graceful shutdown so in‑flight requests finish. Examples include rolling updates with maxSurge/maxUnavailable, blue–green via service label swap for instant rollback, recreate for fast staging, and canary by changing ingress traffic percentages (also shadowing and feature toggles). Code and commands for each strategy are on GitHub.
