OpenStack- or KVM-based virtualization

Ceph is the perfect match to provide storage to an OpenStack environment. In fact, Ceph currently is the most popular choice. OpenStack Cinder block driver uses Ceph RBDs to provision block volumes for VMs and OpenStack Manila, the Shared File System service (FaaS), integrates well with CephFS. There are a number of reasons why Ceph is such a good solution for OpenStack:

• Both are open source projects with commercial offerings
• Both have a proven track record in large-scale deployments
• Ceph can provide block, CephFS, and object storage, all of which OpenStack can use
• It is possible to deploy a hyper converged cluster with careful planning

If you are not using OpenStack or have no plans to use it, Ceph also integrates very well with KVM virtualization.
