According to a new report by Cloud Market, Ubuntu is more than twice as popular on Amazon EC2 as all other operating systems combined. Given that Amazon Web Services has 57% of the public cloud market, Ubuntu is clearly the most popular OS for cloud systems. This is further bolstered by a recent OpenStack survey, which found that more than half of respondents used Ubuntu for cloud-based production environments. Centos was a distant second at 29%, and RHEL came in third at 11%. "In addition to AWS, Ubuntu has been available on HP Cloud, and Microsoft Azure since 2013. It's also now available on Google Cloud Platform, Fujitsu, and Joyent." The article concludes, "People still see Ubuntu as primarily a desktop operating system. It's not — and hasn't been for some time."
