The application that you develop runs as a hosted service in Windows Azure, and the application is built from one or more roles. A role defines a component that may run in the execution environment within Windows Azure. For more information about defining and configuring roles in the service model for a hosted service see, Setting Up a Hosted Service for Windows Azure. Roles that are defined for the hosted service run as role instances in Windows Azure.

The Role class is used to obtain role instance objects. The following code example shows how to retrieve the name of the role and the instance IDs of role instances:

No code example is currently available or this language may not be supported.

You can change the number of role instances that are running by changing the instances count in the ServiceConfiguration.csfg file. For more information about changing the instance count, see How to Scale Applications by Increasing or Decreasing the Number of Role Instances.

noteNote
At least one internal endpoint must be defined for a role to enable instances to be known at runtime. For more information about defining internal endpoints, see How to Define Internal Endpoints for a Role.
