Top cloud infrastructure service providers

When IT organizations evaluate cloud infrastructure providers, the same two consistently rise to the top: Amazon and Microsoft. That’s not likely to change any time soon.

According to Synergy Research Group, Amazon and Microsoft lead the cloud infrastructure service market (Note: This includes IaaS, PaaS and hosted private cloud). Amazon is three times the size of Microsoft and has a clear lead in all major regions and most segments of the market. However, Microsoft is growing much faster, with a 100% year over year growth rate compared to Amazon’s 53%. This isn’t surprising when you consider that enterprise IT organizations are already familiar with Microsoft tools. Transitioning to Azure presents a much lower learning curve than AWS.

IBM and Google round out the top four cloud infrastructure providers, which together account for well over half of the worldwide market. These providers are growing more rapidly than their smaller competitors, with combined revenues growing 68% in Q2. The next 20 largest cloud providers – which includes CenturyLink, Hewlett Packard Enterprise, Rackspace and Oracle – grew by 41%.

Other notable stats:

  • Synergy estimates that quarterly cloud infrastructure service revenues (including IaaS, PaaS and hosted private cloud) have reached $8 billion.
  • Twelve-month revenues are close to $28 billion.
  • North America accounts for over half of the worldwide market.
