About Envoy
A high-performance C++ proxy built for cloud-native microservice deployments.
Envoy acts as a universal data plane for service mesh architectures, providing advanced routing, load balancing, and observability features. Created at Lyft and now a CNCF graduated project used by companies like Airbnb, Netflix, and Uber.
Key Capabilities
- ⚡ High Performance: C++ implementation with minimal memory footprint
- 🔀 Protocol Agnostic: Native HTTP/1.1, HTTP/2, HTTP/3, gRPC, and TCP support
- 🎯 Intelligent Routing: Path-based routing, traffic splitting, and header manipulation
- 🔄 Resilience Patterns: Automatic retries, circuit breakers, and timeout management
- 📊 Rich Metrics: Built-in stats, distributed tracing, and access logging
- 🔌 Dynamic Configuration: xDS APIs for runtime updates without restarts
- 🛡️ Security First: TLS termination, mutual TLS, rate limiting, and authentication
- 🌍 Multi-Protocol: WebSocket, MongoDB, Redis, Postgres wire protocols
Configuration Overview
This stack includes a basic static configuration. For your use case, you should:
- Edit
envoy.yamlto define your routing rules - Configure upstream clusters for your backend services
- Set up listeners for your specific ports and protocols
- Add filters for authentication, rate limiting, or other features
The default setup provides:
- Admin dashboard at port 9901 for monitoring and debugging
- Example HTTP listener at port 10000
- Sample upstream service definition
