Service Mesh Fundamentals
A service mesh is an infrastructure layer for communication between application workloads. It can provide workload identity, encrypted traffic, traffic policy, and telemetry without requiring every service to implement the same network behavior.

Intro
Service Mesh Fundamentals
A service mesh manages service-to-service communication as infrastructure. It gives workloads consistent traffic, security, and observability capabilities through a data plane and a control plane. The data plane handles live traffic. The control plane distributes identity and configuration.
In a proxy-based mesh, an application sends and receives traffic through an associated proxy. Modern meshes can also use node-level or ambient data-plane modes. The implementation varies, but the architectural question stays the same: which cross-cutting network behavior should be consistent across workloads?
