Open Service Mesh

Jan 1, 0001

Definition

Open Service Mesh (OSM) is a lightweight and extensible cloud-native service mesh that runs on Kubernetes. It provides secure, fine-grained control over service-to-service communication by automatically managing TLS encryption, traffic policies, and observability. OSM is designed to be simple to install and operate, integrating seamlessly with Kubernetes environments to enhance security and reliability of microservices.
