# ServiceConnectServiceResource
<a name="API_ServiceConnectServiceResource"></a>

The Service Connect resource. Each configuration maps a discovery name to a Amazon Cloud Map service name. The data is stored in Amazon Cloud Map as part of the Service Connect configuration for each discovery name of this Amazon ECS service.

A task can resolve the `dnsName` for each of the `clientAliases` of a service. However a task can't resolve the discovery names. If you want to connect to a service, refer to the `ServiceConnectConfiguration` of that service for the list of `clientAliases` that you can use.
