Envoy is a high performance edge and service proxy designed for cloud-native applications and modern service-oriented architectures.
It can be deployed alongside applications, used as an ingress or egress proxy, or placed at the network edge, giving operators a consistent data plane for routing, resilience, and observability across distributed systems.
This is free and open source software.
Key Features
- Supports L3/L4 proxying and HTTP L7 processing through a pluggable filter architecture.
- Provides first-class support for HTTP/1.1, HTTP/2, and gRPC traffic.
- Offers dynamic configuration through the xDS APIs for centrally managed updates.
- Includes advanced traffic management features such as load balancing, retries, circuit breaking, and rate limiting.
- Delivers strong observability with statistics, access logging, and distributed tracing.
- Uses an out-of-process design that works with applications written in different languages and frameworks.
