Amazon Web Services is leading the cloud infrastructure market ahead of Microsoft, IBM, Google and Rackspace, reaching a five-year high, according to research.
A report by Synergy Research Group said AWS took in 30% of the global cloud infrastructure service market in Q4 last year, following revenue growth of 25% in the third quarter.
For the full-year of 2014, AWS also came in first place, taking a 28% share of the worldwide market. The second largest holder was Microsoft with 10%, followed by IBM with 7%, Google with 5%, Salesforce with 4% and Rackspace with 3%.
The research also estimates that overall quarterly revenues for the cloud infrastructure service market, including IaaS, PaaS and private and hybrid cloud, is now approaching the $5bn mark, as annual revenues exceed $16bn.
John Dinsdale, chief analyst and research director at Synergy Research Group, said: "Many actual or perceived barriers to cloud adoption have now been removed and the worldwide market is on a strong growth trajectory.
"The momentum that has been built up at AWS and Microsoft is particularly impressive. They have an ever-broadening portfolio of services and they are also benefitting from a slowdown in the super-aggressive price competition that was a feature of the first half of 2014."
