You can do the following way:
AEM can be configured to store data in Microsoft's Azure storage service. It uses the org.apache.jackrabbit.oak.plugins.blob.datastore.AzureDataStore.config PID for configuration.
In order to enable the Azure data store functionality, a feature pack containing the Azure Connector needs to be downloaded and installed. Go to the Adobe Repository and download the latest version from the 1.6.x versions of the feature pack (for example, com.adobe.granite.oak.azureblobconnector-1.6.3.zip).
