Choosing between Envoy and HAProxy involves evaluating several factors including performance, architecture, protocol support, observability, and configuration complexity. HAProxy is known for high performance, stability, and efficiency, making it a strong choice for high-performance edge proxies and traditional enterprise load balancing. Envoy, with its modern architecture, excels in dynamic environments such as Kubernetes and microservices, providing advanced support for protocols like HTTP/2, gRPC, and WebSockets. It also offers superior observability and integration with service mesh solutions.
