Today there’s only 6 cloud providers in the game.  I predict that in 3 years or less there will be only 3 players left i.e., an oligopoly.  Below is the most recent data from Synergy Group to back up my assumption.  

“Amazon Web Services (AWS) remains larger than its four main competitors combined in the cloud infrastructure service market. Microsoft can once again lay claim to having by far the highest revenue growth rate”

“…now six companies that can lay a valid claim to having annual cloud revenue run rates in excess of $5 billion – AWS, IBM, Microsoft, HP, Cisco and salesforce”

AWS Still Bigger than its Four Main Competitors Combined Despite Surging Growth
