详细说明： Microsoft’s Big Data Platforms The world of data is changing in a big way and expectations about how to interact and analyze that data are changing as a result.

Microsoft has been present in the traditional BI space through the SQL Server platform which scales quite satisfactorily into the hundreds of gigabytes range without too much need for specialist hardware or cleve r configuration. Since approximately 2010, Microsoft has also offered a couple of specialist appliances to scale higher: the SQL Server Fast Track Data Warehouse for anything up to 100 terabytes, and the SQL Server Parallel Data Warehouse (PDW) for anything entering the petabyte scale. However, these platforms only deal with relational data and the open-source movement overtook Microsoft (and indeed many other vendors) with the emergence of Hadoop. Microsoft did have a similar platform internally called Dryad but, shortly before Dryad was expected to go live, it was dropped in favor of creating a distribution of Hadoop in conjunction with Hortonworks.1 2 From that decision point, various previews of the platform were made available as on-premises or cloud versions.

The on-premises version is, at the time of this writing, still in preview with no firm release date.
