The previous survey showed Ubuntu OpenStack at 33 percent of production clouds. Ubuntu has seen almost 67 percent growth in an area where Ubuntu was already the market leader. These numbers are a huge testament to the community support Ubuntu OpenStack receives every day."
Red Hat, with its own OpenStack distribution, Red Hat Enterprise Linux (RHEL) OpenStack, is making a fight of it, though. RHEL, while only in third place, doubled its popularity from 8 to 16 percent. CentOS, the free RHEL clone, is the second most popular OpenStack Linux distribution with 20 percent.
One reason Ubuntu is increasing its lead is that Juju, Canonical's application modeling and deployment DevOps tool, has been gaining in popularity. Since the last OpenStack survey, Juju has increased its market share as a cloud deployment/management tool by 50 percent.
