Envoy Proxy
Envoy Proxy is a high-performance, open-source edge and service proxy designed for cloud-native applications. It provides critical networking functions such as load balancing, observability, security, and traffic management for microservices architectures. Originally developed at Lyft, it is now a graduated project of the Cloud Native Computing Foundation (CNF).
Developers should learn Envoy Proxy when building or operating distributed systems, especially in Kubernetes or service mesh environments like Istio, where it handles service-to-service communication, resilience, and security. It is essential for implementing advanced traffic routing, canary deployments, circuit breaking, and collecting detailed metrics and logs in modern cloud applications.
