title: Differences between Azure Data Warehouse and Microsoft Parallel Datawarehouse (PDW)
body: <p>I'd like to know the key differences between Azure Data Warehouse and Microsoft Parallel Datawarehouse (PDW).</p>
  
  <p>I read an article on <a href="https://docs.microsoft.com/en-us/azure/sql-data-warehouse/sql-data-warehouse-overview-what-is" rel="nofollow noreferrer">Azure Data Warehouse</a> here.
  Also, an article on <a href="http://www.jamesserra.com/archive/2014/03/parallel-data-warehouse-pdw-benefits-made-simple/" rel="nofollow noreferrer">Microsoft PDW</a>. </p>
  
  <p>Looking at features and functionalities, they look similar. However, I'd like to know key differences between them and in what circumstances, one is better than other.</p>
