OpenStack Liberty, the 12th release of the open source software for building public, private, and hybrid clouds, offers unparalleled new functionality and enhancements. With the broadest support for popular data center technologies, OpenStack has become the integration engine for service providers and enterprises deploying cloud services.
With 1,933 individual contributors and 285 organizations contributing to the release, Liberty offers finer-grained management controls, performance enhancements for large deployments and more powerful tools for managing new technologies such as containers in production environments.

The new Curvature Network Topology interface offers dynamic and scalable insight into your OpenStack resources.
Powerful block storage management gives you complete control over your networked disks to handle attachments, snapshots and replicas.
The new interface to the Community App Catalog lets you simply launch images and applications created for the community, by the community.
Finer-grained access controls and simpler management features debut in Liberty. New capabilities like common library adoption and better configuration management have been added in direct response to the requests of OpenStack cloud operators. The new version also adds role-based access control (RBAC) for the Heat orchestration and Neutron networking projects. These controls allow operators to fine tune security settings at all levels of network and orchestration functions and APIs.
As the size and scope of production OpenStack deployments continue to grow—both public and private—users have asked for improved support for large deployments. In Liberty, these users gain performance and stability improvements that include the initial version of Nova Cells v2, which provides an updated model to support very large and multi-location compute deployments. Additionally, Liberty users will see improvements in the scalability and performance of the Horizon dashboard, Neutron networking Cinder block storage services and during upgrades to Nova’s compute services.
OpenStack is a single, open source platform for management of the three major cloud compute technologies; virtual machines, containers and bare metal instances. The software also is a favorite platform for organizations implementing NFV (network functions virtualization) services in their networking topologies. Liberty advances the software’s capabilities in both areas with new features like an extensible Nova compute scheduler, a network Quality of Service (QoS) framework and enhanced LBaaS (load balancing as a service).
During the Liberty development cycle we also saw the first full release of the Magnum container management project. Out of the gate, Magnum supports popular container cluster management tools Kubernetes, Mesos and Docker Swarm. Magnum makes it easier to adopt container technology by tying into existing OpenStack services such as Nova, Ironic and Neutron. Further improvements are planned with new project, Kuryr, which integrates directly with native container networking components such as libnetwork.
The Heat orchestration project adds dozens of new resources for management, automation and orchestration of the expanded capabilities in Liberty. Improvements in management and scale, including APIs to expose what resources and actions are available, all filtered by RBAC are included in the new release.
We use OpenStack because it delivers the core services we need in a production cloud platform that can extend to new technologies like containers. The ability to embrace emerging technologies as an open community rather than going solo is a primary reason why we’re sold on OpenStack.
Thank you to the global team of 1,933 developers who delivered the twelfth OpenStack release on time with every critical feature:
