Much ado about OpenStack’s twelfth release, including new features for NFV.

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.

  1. It’s interesting to note, the most reported news from the OpenStack Summit sessions in Tokyo last week was the ongoing concerns about the lack of qualified technical talent to meet IT recruiter demands, and the need to reduce IaaS deployment complexity that increasingly fuels that demand.

  2. Thanks for the insights, David. Skills shortages do seem to be an ongoing problem. I think we should look into that issue more closely in this blog.


  3. Title mentions new NFV features in Liberty yet provides zero details in the blog. Blog points to a session at the Vancouver summit. So lame.


    1. Hi Xaqti –
      I recommend you do check out that video of the session at the Vancouver Summit, as the presenters spend a lot of time delving into the details of NFV in OpenStack and provide insights as to what’s in Liberty (granted, this is a discussion is a projection of NFV plans for the Liberty release). Also, check out the release notes for Liberty [] which are quite detailed. We’ll look around for new video from the summit in Tokyo and try and put together more details about NFV in OpenStack in another post.


    2. Xaqti, I also want to point out that the post details several of the updates in Liberty that are related to NFV, and the ability to support enterprise NFV including Nova Cells v2 and the new extensible Nova compute scheduler, a network Quality of Service (QoS) framework and enhanced LBaaS.
