The cloud computing infrastructure market—IaaS, PaaS, and private hosting—continues to consolidate around the four major providers, as they maintain or even grow market share at the expense of smaller providers.

AWS has continued to grow its revenues more rapidly than the overall market. In other words, AWS is the one to beat, and it will likely remain so for sometime. According to Synergy Research Group’s Q2 2017 data, AWS now has 34 percent of the cloud infrastructure market share, followed by Microsoft at 11 percent, IBM at 8 percent, and Google at 5 percent.

This latest data underscores a long-term trend of consolidation, and that’s something enterprises need a strategy for.

If you have picked a weak cloud provider, meaning one that has not established a sustainable market share, you could find your cloud services turned off in a few years. We already saw this happen a few years ago as several smaller IaaS providers left the market a few years ago. And it will happen again.
