# envoy

An introduction to Envoy Proxy's architecture — listeners, clusters, filters, and the xDS dynamic configuration API. Covers static configuration for standalone use and how Envoy fits into service meshes like Istio.

Advanced Envoy traffic management — configuring retries with exponential backoff, per-request timeouts, weighted canary routing, global rate limiting, and fault injection for resilience testing.

A practical guide to getting started with Istio — installing on Kubernetes, enabling automatic mTLS, configuring VirtualServices for traffic management, and understanding the sidecar injection model.

Resolve Envoy's 'upstream connect error or disconnect/reset before headers' error caused by service mesh misconfiguration, timeout issues, or unreachable backends.

Configure Envoy distributed tracing with Jaeger, expose Prometheus metrics, and build end-to-end observability for your service mesh.

Implement Envoy rate limiting with local token bucket and global Redis-backed strategies to protect your services from traffic spikes.

Deploy Envoy as an edge proxy and sidecar for microservices — listeners, clusters, routes, circuit breaking, retries, and observability features.
