The follow-up to the Folsom release of the OpenStack open source cloud computing platform, OpenStack Grizzly debuted in April 2013 as the seventh release of OpenStack (and was itself succeeded by the Havana release in October 2013).
With OpenStack Grizzly, the OpenStack Foundation has focused on adding broader support for compute, storage and networking technologies as well as greater scalability and ease of operations.
In terms of specific additions, OpenStack Grizzly features native support for VMware ESX and Microsoft’s Hyper-V hypervisors, new “Cells” capabilities that facilitate managing multiple OpenStack compute environments as a single entity, and new block storage options. OpenStack Grizzly also provides more extensive software-defined networking (SDN) functionality.
