The 12th Release of OpenStack, the Liberty release, would answer the requests of a diverse community of the open source software users, including finer-grained management controls, performance enhancements for large deployments and more powerful tools for managing new technologies like containers in production environment.
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.
“Liberty is a milestone release because it underscores the ability of a global, diverse community to agree on technical decisions, amend project governance in response to maturing software and the voice of the marketplace, then build and ship software that gives users and operators what they need,” said Jonathan Bryce, executive director, OpenStack Foundation. “All of this happens in an open community where anyone can participate, giving rise to an extensible platform built to embrace technologies that work today and those on the horizon.”
As the size and scope of production OpenStack deployments continue to grow – both public and private, users have also asked for improved support for large deployments. In Liberty, these users would 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 would 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 would advance 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).
The Liberty release also brings the first full release of the Magnum containers management project. Out of the gate, Magnum supports popular container cluster management tools, Kubernetes, Mesos and Docker Swarm. Magnum would make 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.
BMW, Disney, Wal-Mart
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.
“Notable Fortune 100 enterprises like BMW, Disney, and Wal-Mart have irrefutably proven that OpenStack is viable for production environments,” said Lauren Nelson, senior analyst, Forrester Research. “These are regular companies, not firms that were born digital like Etsy, Facebook, and Netflix. OpenStack’s presence in the market is now accelerating, leveraging the success of these pioneers.”
1,933 individuals across more than 164 organizations contributed to OpenStack Liberty through upstream code, reviews, documentation and internationalization efforts. The top code committers to the Liberty release were HP, Red Hat, Mirantis, IBM, Rackspace, Huawei, Intel, Cisco, VMware, and NEC.
