Istio and why do we need it

on YouTube ↗25m

" summary

Explains how Istio sits on Kubernetes to add a declarative networking API and per-workload sidecar proxies that enforce routing, TLS and policy. Shows concrete configs: Gateways, VirtualServices, DestinationRules used to create header-based canary splits, subset-based load balancing, and gateway-bound ingress; virtual services merge across namespaces and sidecars push updated policies. Demonstrates a request path through gateway → virtual service → subset → service, and notes observability, fail-injection and recovery actually work in this setup.
