Here's Who Made Gartner's 2014 Cloud IaaS Magic Quadrant

Leaders: Microsoft Azure

Microsoft launched Azure Infrastructure Services last year, entering the IaaS market after having already established its strong presence as a provider of platform and software cloud services. The software giant is increasingly focusing on delivering its software products over its expanding cloud through a variety of offerings. Microsoft recently launched ExpressRoute as a high-speed, dedicated connection to Azure through telecom or exchange partners.

Azure is available in multiple data centers in the U.S. and in Ireland, the Netherlands, and much of Asia.
