  This topic describes service mesh for <% vars.product_full %>. 
  
  ## <a id="overview"></a> Overview 
  
  <% vars.product_short %> includes an optional, beta routing plane that uses a service mesh. A service mesh provides traffic management, security and observability for microservices. For more information, see [What is a service mesh?](https://istio.io/docs/concepts/what-is-istio/#what-is-a-service-mesh) in the Istio documentation. Service Mesh in 
  
  <% vars.product_short %> uses [Istio Pilot](https://istio.io/docs/concepts/what-is-istio/#pilot) and [Envoy](https://www.envoyproxy.io/). The Cloud Foundry [istio-release](https://github.com/cloudfoundry/istio-release) packages these components into a BOSH release.
