Global public cloud IaaS industry grew 30% year on year – with AWS holding half of the market

August 02, 2018 / James Bourne

The global infrastructure as a service (IaaS) public cloud services market grew by almost 30% in 2017 to total $23.5 billion (£18bn) according to the latest figures from Gartner – with Amazon Web Services (AWS) securing more than half of the global market.The figures, which appear in the analyst firm’s latest market share analysis, put Amazon Web Services (AWS) well in clear at the top of the tree with Microsoft a clear second place. No surprises there – yet Alibaba takes third place with 4.6% of global market share, ahead of Google and IBM.With 51.8% of the total market, AWS remains supremely dominant in the eyes of Gartner, clocking up revenues of $12.2bn in the process in 2017. Microsoft, at 13.3% share and $3.1bn, pales into second. Yet Gartner argues Amazon did lose market share from 2016, where it held 53.7% of the market albeit with merely $9.8bn in revenues.
