You can scale a data warehouse that you already have, or use Quickstart: create and connect - portal to create a data warehouse named mySampleDataWarehouse. This quickstart scales mySampleDataWarehouse.
Your data warehouse must be online to scale.
SQL Data Warehouse compute resources can be scaled by increasing or decreasing data warehouse units. The [create and connect - portal] quickstart(create-data-warehouse-portal.md) created mySampleDataWarehouse and initialized it with 400 DWUs. The following steps adjust the DWUs for mySampleDataWarehouse.
To change data warehouse units:
Click SQL data warehouses in the left page of the Azure portal.
Select mySampleDataWarehouse from the SQL data warehouses page. The data warehouse opens.
In the Scale panel, move the slider left or right to change the DWU setting.
Click Save. A confirmation message appears. Click yes to confirm or no to cancel.
You've now learned to scale compute for your data warehouse. To learn more about Azure SQL Data Warehouse, continue to the tutorial for loading data.
