Let's go to the preceding diagram and thus to the last element of the Cloud Service architecture, the service endpoint.
The service endpoint (an IP address or URL) is provided by a WebRole and it is the public interface to the outside world.
Each Cloud Service has only one service endpoint, but this does not mean that additional endpoints cannot be provided.
For example, a Cloud Service may have a normal Service Endpoint over the HTTP protocol, while a second endpoint may respond to internal calls (for example, from the intranet) over the TCP protocol:
Like the limitations for web and worker Roles, also the endpoints are limited. The limits are instance input endpoints: 25, input endpoints: 25, internal endpoints: 25.
In the first part of this chapter, we learned about the Cloud Services architecture in a rather simple overview and now it is time to discover the finer details of the Cloud Services.
