OpenStack Users Don't Use All OpenStack Projects

The OpenStack platform is comprised of multiple projects, but not all projects are actually used by all cloud operators. Core services—including Compute (Nova), Identity (Keystone), Image (Glance) and Dashboard (Horizon)—are used by 80 percent or more of OpenStack production deployments.
