It’s hard to think of a business Amazon.com Inc. dominates as convincingly as the market for cloud computing services. Andy Jassy, chief executive officer of the company’s cloud division, Amazon Web Services Inc., likes to brag that his outfit has several times as much business as the next 14 providers combined. Amazon’s next-largest cloud competitor, Microsoft Corp., is less than one-fifth Amazon’s size in terms of sales of infrastructure services, which store and run data and applications in the cloud, according to research firm Gartner Inc. Google, the No. 3 U.S. cloud services provider and the second-largest company in the world by market value, makes one-fifteenth of Amazon’s cloud revenue.
“AWS effectively defined the notion of cloud computing,” says Gartner analyst Ed Anderson. “It’s perceived as the cloud leader and pacesetter.” AWS generated $4.6 billion in sales in the most recent quarter. Every year, it introduces dozens of features and products to retain its edge.
