Windows Azure Cloud Services allow developers to deploy web and worker roles. A web role is used for front-end web applications, while a worker role handles background processing tasks. The service definition file defines the roles and configuration settings. The service configuration file specifies deployment settings like instance counts and diagnostic connection strings for each role. Developers can program the roles using .NET or other SDKs to build multi-tier cloud applications with a web front-end and background worker processes.
