The 12th release of OpenStack is out. There’s plenty to talk about in Liberty, unveiled Oct. 15. Among Liberty’s many new and enhanced features are a few that might capture the attention of telcos that want to use OpenStack as the platform to support network functions virtualization (NFV) services in their networking topologies.
Liberty includes a new extensible Nova compute scheduler, a network Quality of Service (QoS) framework and enhanced LBaaS (load balancing as a service), all of which are features that help to expand OpenStack’s scalability and therefore boost performance and stability of larger deployments, according to an OpenStack Foundation press release and the OpenStack Liberty release notes.
Nova Cells v2 was also introduced. According to OpenStack documentation, Nova has depended on a single logical database and message queue that all nodes use for communication and data persistence, but scaling and providing fault tolerance is difficult. Sometimes, cells are used in large deployments to partition compute nodes into smaller groups, coupled with a database and queue, but there have still been issues. Liberty contains an initial version of Nova Cells v2, an updated cells model designed to support very large, multi-location compute deployments.
Additionally, Liberty users can 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.
Liberty also features common library adoption and better configuration management, as well as 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, according to the OpenStack Foundation.
There are 1,933 individual contributors and 164 organizations who contributed to the release, according to the OpenStack Foundation.
To hear more about NFV, an overview of its evolution, and the ongoing work on NFV within OpenStack, tune into this replay of a presentation at the OpenStack Summit in Vancouver back in May 2015. Red Hat’s Steve Gordon, senior technical product manager, gave the presentation, joined by Intel’s Adrian Hoban and Ericsson’s Alan Kavanagh.
