Microsoft's HDInsight service -- a cloud-based distribution of Hadoop -- is generally available. Microsoft's planned complement for Windows Server has been replaced.



From All About Microsoft:

Microsoft officials also are acknowledging publicly that Microsoft has dropped plans to deliver a Microsoft-Hortonworks developed implementation of Windows Server, which was known as HDInsight Server for Windows. Instead, Microsoft will be advising customers who want Hadoop on Windows Server to go with Hortonworks Data Platform (HDP) for Windows.

Windows Azure HDInsight is "100 percent Apache Hadoop" and builds on top of HDP. HDInsight includes full compatibility with Apache Hadoop, as well as integration with Microsoft's own business-intelligence tools, such as Excel, SQL Server and PowerBI.
