Envoy Proxy Introduction
- Envoy is a powerful L7 proxy and communication bus designed for microservices.
- It offers advantages over other proxies with its terminology and architecture.
Envoy Architecture
- Envoy's architecture distinguishes between downstream (clients) and upstream (backends).
- It groups backend hosts into clusters and uses listeners as frontends.
Network Filters
- Envoy uses network filters to map listeners to clusters, enabling flexible configuration.
- It offers built-in filters for various protocols and allows custom filter development.
