There are plenty of companies that want to rule the online cloud infrastructure market. The top four companies are all from the United States, and they have such a significant lead over the other vendors it might not be possible for them to catch up anytime soon. In a study Synergy Research Group, they show Amazon Web Services, Microsoft, IBM, and Google controlling more than half of the worldwide cloud infrastructure market.
Amazon (AWS) holds a dominant 31% share in the second quarter of this year, with Microsoft (Azure) next with just a 11% share.
Synergy included infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and hosted private cloud services in its figures. They also found that the top four leaders are also growing more rapidly than their smaller competitors, with more than double-digit year over year (YoY) growth rates.
