Leader: Microsoft Azure
The software giant may be the only true challenger to Amazon Web Services at the moment. But Microsoft still lags behind the industry leader on both axes of the Magic Quadrant—behind only slightly in Completeness of Vision, more so in Ability to Execute.
But Microsoft is throwing everything it's got at building out Azure's technological capabilities and market presence, adeptly leveraging the ubiquity of its products in the corporate data center.
Microsoft's well-known brand and existing customer relationships, combined with experience running consumer Internet properties, deep investments in engineering and an innovative roadmap are the reason "Azure is frequently chosen for strategic adoption by organizations with a strong commitment to Microsoft technologies," Gartner noted.
