Amazon’s cloud service, AWS, far surpasses its competitors in market share at 32%, racking up revenues of $16.1 billion.

TechCrunch Reports Combined Cloud 12-Month Revenues at $164 Billion

Based on reports from the three top cloud vendors—Amazon, Microsoft and Google—the market value has hit $45 billion with an incredible 37% growth for the quarter, according to Synergy Research.

The story on TechCrunch about the cloud’s rapid growth notes that even computer chip shortages haven’t had an impact on the sector’s impressive expansion. The three leading companies comprise 70% of the business in the cloud sector. Amazon was the top dog:

“Amazon reported $16.1 billion in revenue, up from $11.6 billion a year ago,” says the TechCrunch story, written by Ron Miller. “If you’re doing the math at home, you will note that this number is not one-third of $45 billion, and that’s because Synergy tracks infrastructure, platform services and hosted private clouds, and subtracts any revenue that’s not purely from these buckets such as consulting or hardware.”

The second company on the list, Microsoft, had a whopping 50% growth for its Azure cloud services, at $9 billion in total, up from $8.4 billion in the previous quarter.

Google has a much smaller 10% market share, raising $4.5 billion, which increased from $4.2 billion the previous quarter, and up from $2.9 billion a year ago.

John Dinsdale, the chief analyst at Synergy, said that the clout of the big three U.S. cloud companies gives them the leverage to gain access to computer chips and other needs.

“These companies are pretty good at managing their supply chains and they are such huge customers that you have to believe they will get preferential treatment from suppliers,” Dinsdale said. “There are also a few knobs they can adjust in terms of things like build versus lease decisions, extending server lifespan a little and switching workloads to different geographies. They now have enormous and geographically dispersed data center networks that gives them a lot of wiggle room to get what they need.”
