Amazon Web Services and Microsoft Azure took the two leadership positions in its latest Magic Quadrant report for Magic Quadrant for Cloud Infrastructure as a Service, Worldwide. Amazon is the clear market leader and, according to Gartner, claims more than 10 times the computing capacity of the other 14 vendors represented in its Magic Quadrant report. Other vendors represented in the report include Google, Rackspace, IBM SoftLayer and VMware vCloud Air. Gartner estimates that the IaaS space will experience growth of 33% in 2015 and become a $16.5B market globally with an annual growth rate of 29.1% through 2019. In a press release about the report, Gartner noted that “the market for cloud infrastructure as a service (IaaS) is in a state of upheaval, as many service providers are shifting their strategies after failing to gain enough market traction.” The report’s finding that Amazon Web Services and Microsoft Azure represent the two market leaders means that the rest of the space will need to significantly differentiate their product offerings to flourish in an increasingly competitive space.
