The following are the Azure deployment scenarios.
|Base Storage Layer||Storage - WASB||Storage - ADLS||Storage - Azure SQL DB||Storage - SQL DW||Cluster|
install for WASB
install for ADLS
Legend and Notes:
|Deployment Scenario||Description of the Azure-connected deployment|
Location where the is installed in this scenario.
|Base Storage Layer|
When the is first installed, the base storage layer must be set.
For more information, see Set Base Storage Layer.
|Storage - WASB|
For read/write access to WASB, the base storage layer must be set to WASB. For more information, see Enable WASB Access.
|Storage - ADLS||For read/write access to ADLS, the base storage layer must be set to HDFS. For more information, see Enable ADLS Access.|
|Storage - Azure SQL DB||For Azure installs, you can optionally create a connection to an Azure SQL Database. For more information, see Create Azure SQL Database Connections.|
|Storage - SQL DW||For Azure installs, you can optionally create a connection to an Azure-hosted instance of SQL DW. For more information, see Create SQL DW Connections.|

The following table describes the different Azure components that can host or integrate with the . Combinations of one or more of these items constitute one of the deployment scenarios listed in the following section.
|Azure Service||Description||Base Storage Layer||Other Required Azure Services|
Microsoft Azure deployments can integrate with an HDI cluster, which can be pre-existing or created at the time of deployment. See Configure for HDInsight.
Base storage layer can be HDFS (for ADLS) or WASB.
Optionally, you can integrate the with an Azure Databricks cluster. See Configure for Azure Databricks.
|Base storage layer can be HDFS (for ADLS) or WASB.|
Windows Azure Storage Blobs (WASB) extends HDFS to enable access to storage blobs that have not been deployed into the HDI cluster. See Enable WASB Access.
Base Storage Layer = WASB
Active Data Lake Store (ADLS) provides a highly scalable file-based storage system within HDI cluster. See Enable ADLS Access.
Base Storage Layer = HDFS
The following database connections are optional.
You can read from and write to Hive, a data warehouse built on top of HDI.
You can read from and write to SQL Data Warehouse, a scalable data warehouse solution for Azure.
You can read from SQL DB, a SQL Server variant for Azure.
