New data from Synergy Research Group shows that Q4 spend on cloud infrastructure services jumped 45% from the fourth quarter of 2017, giving a full-year growth rate of 48% in 2018. Notably the growth rates seen throughout 2018 were higher than those achieved in 2017.
Amazon, the clear market leader, nudged its market share upwards and remains equivalent in size to its next four competitors combined. Meanwhile revenue growth at Microsoft, Google and Alibaba again far surpassed overall market growth rate, so all three gained substantial market share, with Microsoft in particular jumping ahead. The market share gains of these four was primarily at the expense of small-to-medium sized cloud operators, who collectively have lost five percentage points of market share over the last four quarters. Many of those smaller players are still growing revenues but find themselves unable to keep pace with the market leaders. Among the leaders, IBM’s prime focus is a little different from the others as it remains the strong leader in the hosted private cloud services segment of the market.
With most of the major cloud providers having now released their earnings data for Q4, Synergy estimates that quarterly cloud infrastructure service revenues (including IaaS, PaaS and hosted private cloud services) were approaching $20 billion, giving a full-year total of almost $70 billion.
Public IaaS and PaaS services account for the bulk of the market and those grew by 49% in Q4. In public cloud the dominance of the top five providers is even more pronounced, as they control over three quarters of the market. Geographically, the cloud market continues to grow strongly in all regions of the world.
