New findings from Synergy Research highlight the cloud market is still dominated by AWS, Google, Microsoft and IBM, as the pack is seemingly struggling to gain ground in the race for market share.

AWS still leads the way in the segment, accounting for roughly 31% of the global market share, with IBM, Google and IBM collectively accounting for the next 22%. The next 20 players in the market, companies such as HPE, VMWare and Alibaba for example, account for a collective 27%. AWS year-on-year growth was estimated at 57% while Google and Microsoft both demonstrated more than 100% growth over the same period.

“This is a market that is so big and is growing so rapidly that companies can be growing by 10-30% per year and might feel good about themselves and yet they’d still be losing market share,” said John Dinsdale, Chief Analyst at Synergy Research Group. “The big question for them is whether or not they are building a sustainable and profitable business. This can be done by focusing on specific regions or specific services, but the bulk of the market demands huge scale, a broad footprint, very deep pockets and a long-term corporate focus.”

Worryingly for the rest of the pack outside of the top four, the gap would appear to be growing as AWS, Google, Microsoft and IBM are pulling further ahead. The 20 companies outside the top four averaged year-on-year growth of approximately 41%, though Synergy claim the cloud segment grew more than 50% over the course of Q1.

The team estimate the quarterly cloud infrastructure service revenues, which include IaaS, PaaS and private & hybrid cloud, has now surpassed the $7 billion milestone, with the US accounting for roughly 50% of the worldwide market share.
