 ** virtualServiceName **   <a name="appmesh-Type-VirtualServiceBackend-virtualServiceName"></a>
The name of the virtual service that is acting as a virtual node backend.  
App Mesh doesn't validate the existence of those virtual services specified in backends. This is to prevent a cyclic dependency between virtual nodes and virtual services creation. Make sure the virtual service name is correct. The virtual service can be created afterwards if it doesn't already exist.

A reference to an object that represents the client policy for a backend.
