Newest OpenStack® Release Expands Services for Software-Defined Networking, Container Management and Large Deployments
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 release cycle, the community shifted the way it organizes and recognizes upstream projects, which became known by community members as the “big tent.” Ultimately, the change allows the community to focus on a smaller set of stable core services, while encouraging more innovation and choice in the broader upstream ecosystem.
“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. 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.”
