Overview of Azure SQL Data Warehouse
Azure SQL Data Warehouse (SQL DW) is a petabyte-scale MPP analytical data warehouse built on the foundation of SQL Server and run as part of the Microsoft Azure Cloud Computing Platform. Like other Cloud MPP solutions, SQL DW separates storage and compute, billing for each separately. Unlike many other analytical data warehouse solutions, SQL DW abstracts away physical machines, and represents compute power in the form of data warehouse units (DWUs) which allow users to seamlessly and easily scale compute resources at will.
Azure SQL Data Warehouse is part of the Microsoft Azure Cloud Computing Platform, which makes choosing this database a virtual no-brainer for companies already invested in the Microsoft technology stack.
