LongCloud Service Mesh is a fully managed service mesh that provides service networking, traffic management, and security across hybrid and multicloud deployments. It supports VMs, containers, and serverless workloads with zero-trust security, fault injection, and built-in observability.Linkerd is a service mesh that adds security, observability, and reliability to Kubernetes clusters. 100% open source, CNCF graduated, and written in Rust, it is designed for simplicity without the complexity of other meshes.
