An Envoy proxy is an open-source edge and service proxy designed for cloud-native applications. It is used to manage network traffic between services in a microservices architecture, providing features such as load balancing, service discovery, health checking, and observability.
Envoy Proxy is used to facilitate communication between microservices, improving the reliability and security of service-to-service communication. It can be deployed as a sidecar proxy alongside each microservice or as an edge proxy at the network perimeter.
Envoy is used because it offers advanced traffic management capabilities, such as dynamic configuration, traffic routing, retries, circuit breaking, and fault injection. These features help to build resilient, scalable, and secure distributed systems.
Envoy software is used for managing service-to-service communication in microservices architectures. It provides observability by generating metrics and logs, and it enhances security through mutual TLS and fine-grained access control. It also simplifies traffic management and load balancing.
Envoy Proxy can function as an API gateway, handling external client requests and routing them to the appropriate services within a microservices architecture. It provides authentication, authorization, rate limiting, and other API gateway features, making it suitable for managing API traffic.
