All service meshes and, by extension, Istio seeks to automate complex infrastructure operations, like networking and security. That means there will always be complexity in its APIs, but Istio will always aim to solve the needs of operators, while continuing to evolve the API to provide robust building blocks and prioritize flexibility through role-centric abstractions.

The data plane is the part of the mesh that directly controls communication between workload instances.

Istio's data plane uses intelligent [Envoy](#envoy) proxies deployed as sidecars to mediate and control all

traffic that your mesh services send and receive.
