Istio 101: Open Source Service Mesh for Microservices

on YouTube ↗34m

" summary

Istio runs as an istio sidecar proxy that auto‑injects into pods and captures all network calls, while OpenCensus adds tracing and metrics inside app code via the open census OC HTTP handler. Demo deploys to GKE, uses Jaeger and Prometheus as collectors, shows combined traces across services, and exposes a custom “fib count” metric. Sampling is set to always for the demo; initial helm/app install fails then recovers; Istio API is unstable at 0.6–0.8 so expect version drift.
