 Key Vault is used to store certificates that are associated to Cloud Services (extended support). Key Vaults can be created through the [Azure portal](/azure/key-vault/general/quick-create-portal) and [PowerShell](/azure/key-vault/general/quick-create-powershell). Add the certificates to Key Vault, then reference the certificate thumbprints in Service Configuration file. You also need to enable Key Vault for appropriate permissions so that Cloud Services (extended support) resource can retrieve certificate stored as secrets from Key Vault.

 A cloud service is created from three components, the service definition *(.csdef)*, the service config *(.cscfg)*, and a service package *(.cspkg)*. Both the **ServiceDefinition.csdef** and **ServiceConfig.cscfg** files are XML-based and describe the structure of the cloud service and its configuration. We collectively call these files the model. The **ServicePackage.cspkg** is a zip file that is generated from the **ServiceDefinition.csdef** and among other things, contains all the required binary-based dependencies. Azure creates a cloud service from both the **ServicePackage.cspkg** and the **ServiceConfig.cscfg**.
 
 Once the cloud service is running in Azure, you can reconfigure it through the **ServiceConfig.cscfg** file, but you can't alter the definition.
