MOSN (Modular Open Smart Network) is a cloud-native network proxy written in Go language. It is open sourced by Ant Group and verified by hundreds of thousands of production containers in 11.11 global shopping festival. MOSN provides the capabilities of multiple protocol, modularity, intelligent and security. It integrates a large number of cloud-native components, and also integrates a Envoy network library, which is high-performance and easy to expand. MOSN and Istio can be integrated to build Service Mesh, and can also be used as independent L4/L7 load balancers, API gateways, cloud native Ingress, and etc.
