4. Google

Google Cloud Platform has launched.

Google can only claim 4 percent of the market with its public cloud offerings, but in the fourth quarter the Mountain View, Calif.-based Internet giant saw 108 percent year-over-year growth, outpacing everyone other than warp-speed Microsoft Azure.

App Engine and Compute Engine, Google's Platform-as-a-Service and Infrastructure-as-a-Service offerings, respectively, maintain fourth place in the cloud market.

"Google has a lot of the foundation assets and skills that are needed, but cloud doesn’t seem to be getting the management attention and corporate focus that are needed in order to really challenge AWS and Microsoft," Dinsdale told CRN.
