| description.long | A minimal service mesh for Kubernetes applications that delivers security, observability, and reliability capabilities. It automatically encrypts inter-service communication and supports federation across multiple Kubernetes clusters. | A cloud-native service mesh that injects Envoy proxies to manage traffic, enforce security policies, and provide observability across microservice environments on Kubernetes. It uses SMI APIs for configuration and supports automatic mutual TLS. |
