Azure is closing the gap with Amazon's (AMZN) - Get Report AWS, a Credit Suisse analyst said Monday, citing a report that suggests rising adoption of Microsoft's  (MSFT) - Get Report cloud computing service.

The report said that overall Azure adoption grew from 45% to 52% to narrow the gap with AWS. As a result, the report said, Azure adoption has now reached 85% of AWS adoption, up from 70% last year.

"Azure continues to catch up with AWS overall especially among enterprises, where Azure adoption increases slightly from 58% to 60%, while AWS adoption in this group is relatively flat at 67%. This puts Azure with 89% of the AWS adoption based on the overall number of respondents using each cloud," the Cloud Report said, noting that Google maintains its third-place position, increasing slightly from 18% to 19% adoption.
