The following are the Azure deployment scenarios.
|Base Storage Layer||Storage - WASB||Storage - ADLS||Storage - 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 - SQL DB||For Azure installs, you can optionally create a connection to an Azure-hosted instance of SQL DB. For more information, see Create SQL DB 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.|
List of Hadoop cluster types that are supported for integration and job execution at scale.
All Azure installations are executed through the Azure Marketplace. Then, the platform can be integrated with a pre-existing HDI cluster or a cluster that you create as part of the installation.
For more information, see Install from Azure Marketplace.
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|
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 write 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.
