OpenStack Grizzly was launched on April 4, 2013 and contains over 230 new features that enhance the OpenStack platform’s computing power and ability to integrate with other technologies. The release was enabled by the collective work of 517 contributors who merged 7,620 software patches. More than 45 companies employed developers that contributed to the release including Red Hat, Rackspace, IBM, HP, Nebula, Intel, eNovance, Canonical, VMware, Cloudscaling, DreamHost and SINA. Given that OpenStack is used in production environments by the likes of Best Buy, Comcast, CERN, HP, NSA and Samsung, the Grizzly release focused on supporting the day to day operational work required to manage IaaS platforms based on OpenStack distributions.
Key features of Grizzly include the following:
•Support for VMware ESX and Microsoft Hyper-V hypervisors, whereas previously OpenStack had focused on the KVM and Xen hypervisors.
•Support for bare metal provisioning
•Enhanced OpenStack compute scalability by means of “cells” that manage distributed clusters alongside a design that reduces the centrality of a core database via a “NoDB” architecture
•Enhanced ability to automate the management of storage platforms by means of quotas
•Ability to manage diverse storage platforms from a central point of access
•Support for additional third party storage solutions such as Ceph/RBD, Coraid, EMC, Hewlett-Packard, Huawei, IBM, NetApp, Red Hat/Gluster, SolidFire and Zadara.
•Advanced support for software defined networking (SDN) that allows users to write rules to configure networking infrastructures from a broad array of virtualized networking platforms that now includes Big Switch, Hyper-V, PlumGrid, Brocade and Midonet. Previously, OpenStack had supported the Open vSwitch, Cisco UCS/Nexus, Linux Bridge, Nicira, Ryu OpenFlow, and NEC OpenFlow SDN platforms.
Jonathon Bryce, Executive Director of the OpenStack Foundation, remarked on the maturity of the OpenStack software development process as follows:
The Grizzly release is a clear indication of the maturity of the OpenStack software development process, as contributors continue to produce a stable, scalable and feature-rich platform for building public, private and hybrid clouds. The community delivered another packed release on schedule, attracting contributions from some of the brightest technologists across virtualisation, storage, networking, security, and systems engineering. They are not only solving the complex problems of cloud, but driving the entire technology industry forward.
Here, Bryce notes how OpenStack Grizzly features important enhancements across a wide range of attributes such as virtualization, storage and networking. Central to these enhancements is a significant increase in OpenStack’s ability to integrate with other virtualization, storage and networking vendors in ways that dramatically enhance the attractiveness of the OpenStack product given the inherent heterogeneity of enterprise IT platforms. Expect subsequent releases to add more orchestration and automation to the OpenStack platform, most likely beginning with the Havana release in October 2013.
