Microsoft today announced that, starting 3rd April, 2014, they will be renaming Windows Azure to Microsoft Azure, saying that the change in the name reflects Microsoft’s strategy. Microsoft is focused on making Azure as the public cloud platform for customers as well as for our own services Office 365, Dynamics CRM, Bing, OneDrive, Skype, and Xbox Live.
Said Microsoft in a blog post:
Our commitment to deliver an enterprise-grade cloud platform for the world’s applications is greater than ever. Today we support one of the broadest set of operating systems, languages, and services of any public cloud—from Windows, SQL and .NET to Python, Ruby, Node.js, Java, Hadoop, Linux, and Oracle. In today’s mobile-first, cloud-first, data-powered world, customers want a public cloud platform that supports their needs—whatever they may be—and that public cloud is Microsoft Azure.
Microsoft had originally pushed Windows Azure as a cloud-based version of Windows Server, but seeing that Azure now supports several non-Windows systems, services and languages, the rebranding from Windows Azure to Microsoft Azure does make sense.
