Astara is born to simplify networking for OpenStack Liberty, claims Akanda

opensourceSystems built on OpenStack now have better management options, according to Akanda, which has unveiled its new Astara Liberty system for network orchestration.

Akanda, which contributed to the recently launched OpenStack Project Astara, announced the new Liberty release at OpenStack Summit Tokyo. The new Astara Liberty release is Akanda’s debut contribution to the project. The makers claims it gives OpenStack operators vendor-agnostic network orchestration platform for everything that lies between layers three and seven on the network services stack.

The design criteria for Liberty is to cut complexity and make Neutron implementations more scalable. It achieves this by dispensing with the need for multiple plugins and software defined networking (SDN) controllers. By orchestrating these network functions from different providers on bare metal, virtual machines and containers, it has given cloud developers more options and more stability, claims Akanda.

These ‘scalability, flexibility and stability’ improvements are achieved because Akanda’s Liberty release gives developers more configuration choices, faster provisioning, smoother integration, higher levels of availability and fuller compatibility, claims the vendor. Among the mechanisms for delivering these improvements are a new type of new load balancer driver, more Neutron resources and Cumulus Networks integration and support for Dynamic Lightweight Network Virtualization.

“The goal of Astara is to make Networking and DevOps’ lives easier,” said Akanda CEO Henrik Rosendahl. The culture of traditional and expensive single vendor lock-ins must be replaced by a massively simplified OpenStack networking range, he said.

The Liberty release demonstrates the power of the big tent approach to OpenStack, claimed Simon Anderson, CEO of DreamHost and OpenStack Foundation board member. “It’s fantastic to see new open source projects extend and simplify the platform,” said Anderson.

OpenStack Liberty release features enhancements for SDN and containers

OpenStack SummitThe twelfth release of OpenStack will tackle the cloud software toolset’s size limitations and will offer new options for software defined networking, says the Openstack Foundation.

The new version, Liberty, will help cloud software builders to create more manageable and scalable enterprise services with ‘the broadest support for popular data centre technologies’ the foundation says.

The OpenStack Foundation says Liberty was designed in response to user requests for more detailed management controls. OpenStack has also been criticised for its inability to step up to large scale installations. As a result, its operating core has been strengthened and its production environment will include more powerful tools for managing new technologies, such as containers.

Improvements include a new common library adoption, better configuration management and a new role-based access control (RBAC) for the Heat orchestration and Neutron networking projects. These control improvements, which were specifically requested by cloud operators, will allow them to fine tune security settings at all levels of network and orchestration functions and APIs.

OpenStack’s scalability challenges are to be tackled with an updated model to support very large and multi-location systems. The foundation also promised that Liberty users will see better scaling and performance in the Horizon dashboard, Neutron networking Cinder block storage services and during upgrades to Nova’s computing services.

Liberty also marks the first full OpenStack use of the Magnum containers management project. Magnum will support popular container cluster management tools Kubernetes, Mesos and Docker Swarm. Magnum aims to simplify the adoption of 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.

The Heat orchestration project promises ‘dozens’ of new resources for management, automation and orchestration of the expanded capacity of Liberty.

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.
