Several independent cloud companies depend on a unique operating system that allows sysadmins to take advantage of the numerous resources that might be present in a datacentre, notably compute power or storage or networking capability.

Of note are the Zun Capsules, which is roughly equal to Kubernetes Pods, which use Neutron as the networking component, and Cinder as the block storage. This allows for a Kubernetes-like environment similar to other Cloud vendors. Additional information about the various OpenStack components can be found here.
