- It is a modern Layer7(App) and Layer3(TCP) proxy
- Incredibly modernized version of reverse proxies like NGINX, HAProxy
- It is used in many projects: Istio service mash, API gateway products, etc.
- Interesting part: Programming via API instead of file (xDS protocol)
- Developed by Matt Klein at Lyft
- Donated to CNCF(Kubernetes, gRPC, etc.) It graduated from there.
- Those who integrate Envoy into their infrastructure: Google, AWS, etc.
- It has support for Wire protocols(Redis, Memcached, MySQL, MongoDB, etc.)
- RPC level LB instead of connection-level LB
- Metrics(L7 HTTP metrics)
- Request count
- Latency
- Error rate
- Status code
- Bytes received/sent
- Envoy's own metrics(CPU/Memory, TCP connection, Bytes, Bandwidth, QPS)
- Distributed Tracing
- A monitoring method that shows how long the RPCs between microservices keep and where they go.
- Add TRACING HEADER if missing in incoming requests
- Upload TRACEs to a certain location for requests coming to the server
- Request In TRACE ID, start, end(Response)
