OpenStack
Cloud Infrastructure for Virtual Machines, Bare Metal, and Containers
OpenStack is open source cloud infrastructure software for managing large pools of compute, storage, and networking resources through APIs or a dashboard. It supports virtual machines, bare metal, and containers, and can be deployed on-premises, in public cloud data centers, or at the edge. Beyond infrastructure-as-a-service, additional components provide orchestration, fault management, and service management to support high availability of user applications.
Named components include Nova (compute), Cinder (block storage), Swift (object store), Neutron (networking), Keystone (identity), Glance (image service), Horizon (dashboard), Heat (orchestration), Ceilometer (metering), Aodh (alarming), Panko (event indexing), Ironic (bare metal provisioning), Manila (shared filesystems), Trove (database as a service), Magnum (container orchestration), Sahara (big data processing), and the openstackclient command-line interface. Deployment tools include OpenStackAnsible, openstack-ansible, and kolla-ansible. The project is provided under the Apache 2.0 license and is supported by the OpenInfra Foundation.
OpenStack is aimed at organizations operating their own cloud infrastructure across on-premises, public cloud, edge, telecom, and NFV environments. It is distributed as open source software, with no pricing or packaging details stated on these pages; related services such as managed private clouds, training, and certification are offered separately through the Marketplace and community programs.
