 The service definition file defines the service model for an application. The file contains the definitions for the roles that are available to a Cloud Service, specifies the service endpoints, and establishes configuration settings for the service. Configuration setting values are set in the service configuration file, as described by the [Cloud Service (extended support) Configuration Schema](schema-cscfg-file.md)).
