Envoy Proxy is a modern, high-performance edge and service proxy that adds resilience and observability to services without affecting their implementation. It can proxy any TCP protocol, including SSL, and supports HTTP/2, making it an attractive option for applications requiring robust networking capabilities. Envoy's architecture allows it to operate at layers 3, 4, and 7 simultaneously, providing flexibility in configuration and performance. The tool is extensible, but its complexity requires careful consideration. Envoy's mesh architecture enables the creation of multiple edge Envoys and service Envoys that work together to provide a resilient and observable system. The configuration file consists primarily of listeners and clusters, with filters requiring their own complex configuration. Envoy supports various load balancing methods, including round-robin, weighted least requests, and panic thresholds, making it suitable for applications requiring robust networking and scalability. With its vendor-neutral governance and large community, Envoy is an attractive option for projects seeking a single piece of software to support their needs.
