Amazon Web Services (AWS) is maintaining its dominant share of the public cloud services market at over 40 percent, said Synergy Research Group.
Microsoft, Google and IBM are gaining ground in the public cloud services market at the expense of smaller players.
Microsoft, Google and IBM have increased their worldwide market share by almost five percentage points over the last year and together now account for 23 percent of the total public IaaS and PaaS market, helped by particularly strong growth at Microsoft and Google.
Alibaba and Oracle continue to grow at impressive rates.
Quarterly public cloud infrastructure service revenues including both public IaaS and public PaaS have reached well over $7 billion and continue to grow at almost 50 percent per year.
If managed private cloud services are included, quarterly cloud revenues are well over $9 billion.
IBM continues to lead the managed private cloud, while Rackspace and traditional IT service providers feature more prominently.
“Achieving and maintaining a leadership position in this market takes huge ongoing investments in infrastructure, a continued expansion in the range of cloud services offered, strong credibility with the large enterprise sector, consistently strong execution, and the wholehearted and long-term backing of senior management,” said John Dinsdale, chief analyst and research director at Synergy Research Group.
