Service Mesh for developers

" summary

Istio runs as a control plane (istiod) that programs Envoy sidecars per pod to do routing, observability (Kiali) and auth; the demo shows declarative traffic control—via virtual services—doing a 95/5 traffic split and later a 50/50 shift to perform canary rollouts without redeploys. Istio issues and auto-rotates certs (mTLS automatic rotation), supports header routing and chaos-style fault injection (example: 5s delay injected at 0.1% and 400 responses), and works on Kubernetes via namespace sidecar injection; trade-offs shown: extra CPU/memory and two extra proxy hops.
