OpenStack is the open-source cloud operating system for building self-hosted IaaS at datacenter scale, governed by the Open Infrastructure Foundation since its 2010 launch by NASA and Rackspace. Its modular services cover compute (Nova), networking (Neutron), block storage (Cinder), and object storage (Swift), typically running on KVM. It suits telcos, research institutions, and large organizations that need a programmable private or public cloud on their own hardware. The software is free under the Apache 2.0 license; commercial distributions and managed offerings are available from vendors such as Red Hat, Canonical, and Mirantis.
