Open Service Mesh

Open Service Mesh (OSM) is a lightweight, extensible, cloud-native service mesh that allows users to uniformly manage, secure, and get out-of-the-box observability features for highly dynamic microservice environments. The OSM project builds on the ideas and implementations of many cloud-native ecosystem projects including Linkerd, Istio, Consul, Envoy, Kuma, Helm, and the SMI specification. OSM runs an Envoy based control plane on Kubernetes, can be configured with SMI APIs, and works by injecting an Envoy proxy as a sidecar container next to each instance of your application. The proxy contains and executes rules around access control policies, implements routing configuration, and captures metrics. The control plane continually configures proxies to ensure policies and routing rules are up to date and ensures proxies are healthy.
