New Q3 data from Synergy Research Group shows that spend on cloud infrastructure services jumped 45% from the third quarter of 2017. This was a little lower than the growth rate achieved in the first two quarters of the year, but compared favorably with growth rates achieved throughout 2017. Revenue growth at Microsoft, Google, and Alibaba again far surpassed overall market growth rate, so all three gained market share with Microsoft in particular jumping ahead.
Market leader Amazon maintained its dominance and remains bigger than its next four competitors combined. Its sheer scale prevents it from growing as fast as the chasing pack, but it still managed to nudge up its market share a percentage point to a little over 34%. The market share gains of these four came at the expense of small-to-medium-sized cloud operators. While many of those smaller providers are seeing reasonable revenue growth, they are lacking the scale and financial muscle of the leaders and are unable to keep pace with their larger competitors. Meanwhile IBM market share dropped off the pace a little but remained at comfortably over 7%, thanks primarily to its strong leadership in hosted private cloud services.
With most of the major cloud providers having now released their earnings data for Q3, Synergy estimates that quarterly cloud infrastructure service revenues (including IaaS, PaaS, and hosted private cloud services) are now well over $17 billion. The Q3 growth rate of 45% compares with a full-year 2017 growth rate of 44% and a 2016 growth rate of 50%. Public IaaS and PaaS services account for the bulk of the market and those grew by 51% in Q3. In public cloud the dominance of the top five providers is even more pronounced, as they control almost three quarters of the market. Geographically, the cloud market continues to grow strongly in all regions of the world,
“This is another really strong set of numbers both for the leading cloud providers and for the market as a whole,” said John Dinsdale, a chief analyst at Synergy Research Group. “The growth rates are tailing off at some of the leading cloud providers but that is just the law of large numbers kicking in. You cannot keep on growing at 100% when you reach massive scale. Interestingly, the role model for sustainable growth is market leader Amazon. Over the last ten quarters the AWS year-on-year growth rate in these markets has been pretty steady and has averaged just a little under 50%. Given the need for huge scale, most cloud providers outside of the top five are being forced to focus on market niches or specific geographic regions.”
