Implementing Sidecars Microservice Pattern using Envoy Proxy

on YouTube ↗01h 07m

" summary

Hands-on demo builds two services (product in Python Flask, inventory in Java Spring) deployed with Envoy Proxy as per-container sidecars, configured via Docker Compose and YAML clusters; authentication uses Keycloak JWT checks and a custom Lua filter for request logging. Requests route product→product-sidecar→inventory-sidecar, the demo shows token rejection and expected 500/404 behavior, and covers admin metrics, tradeoffs (extra latency and resource overhead) and when to prefer sidecars.
