![Service Mesh Architecture](/images/istio/istio-intro1.png)

A service mesh is a dedicated infrastructure layer for handling **service-to-service communication**. It’s responsible for the reliable delivery of requests through the complex topology of services that comprise a modern, cloud native application.

Service mesh solutions have two distinct components that behave somewhat differently:

* The <span style="color:orange">**data plane**</span> is composed of a set of intelligent proxies (Envoy) deployed as sidecars. These proxies mediate and control all network communication between microservices along with Mixer, a general-purpose policy and telemetry hub.
* The <span style="color:orange">**control plane**</span> manages and configures the proxies to route traffic. Additionally, the control plane configures Mixers to enforce policies and collect telemetry.
