Liberty Is First OpenStack Release Under 'Big Tent' Model
The Liberty release, the second major OpenStack update this year, includes a wealth of new projects and features, while core technologies continue to evolve.The OpenStack Liberty release, set to become generally available on Oct. 15, will provide users of the open-source cloud platform with new projects and features. The second major OpenStack update in 2015, the Liberty release follows Kilo, which debuted on April 30. OpenStack Liberty is noteworthy for many reasons, not the least of which is the fact that it is the first release under the "Big Tent" model, which takes a more inclusive approach for projects. As such, with OpenStack Liberty, there are more new projects as part of the coordinated release than ever before, including SearchLight search, Zaqar messaging, Barbican key manager, Manila shared file system and Designate DNS services among others. "OpenStack is a platform for integrating a wide variety of technologies," Jonathan Bryce, executive director of the OpenStack Foundation, told eWEEK. "With the Big Tent shift, it has allowed people within the OpenStack community to select different focus areas, so we're seeing a lot of innovation." The SearchLight search project in OpenStack Liberty is a new effort that has come up in the last year, Bryce said. SearchLight uses the open-source ElasticSearch technology to enable users to query across an OpenStack deployment. Bryce noted that OpenStack has been using ElasticSearch as part of its development process for several years to search though development logs and test results. He added that members of the OpenStack community thought about how to evolve the limited use of ElasticSearch within OpenStack development into a full OpenStack cloud service, which is now what SearchLight represents.
As an integration platform, OpenStack as a platform always seeks to enable multiple technology options within any given service, and SearchLight is likely not going to be an exception. Currently, SearchLight relies on ElasticSearch, but there is a plug-in system that is part of the overall architecture, Bryce said.
