OpenStack networking and orchestration: What's possible?
This article is part of the Network Evolution issue of March 2014 Vol.5 / No.2
OpenStack, the most popular open source cloud infrastructure platform, has evolved rapidly in a few short years to become a major factor in the growth and adoption of cloud computing. But while much of the attention has been on OpenStack's compute functions, it has also opened up a new world in networking, enabling engineers to automate and orchestrate network resources the way they would virtual machines. At the heart of these capabilities is OpenStack's Neutron application programming interface (API), which can be used to integrate the provisioning and management of these network resources into the orchestration of the overall IT infrastructure. Neutron's open networking capabilities handle a wide range of tasks, including the management of both networks and IP addresses. Users can create their own networks, control traffic and connect servers using Neutron, while administrators can apply OpenFlow and similar technologies to deliver software-defined networking, multi-tenancy and high levels of scalability, according to John ...
