Big, furry and scalable

OpenStack Grizzly released into the wild

Rackspace reduce involvement as Red Hat become most prolific contributors to Infrastructure-as-a-Service project.

seventh major release of Infrastructure-as-a-Service project
OpenStack, codenamed ‘Grizzly’, is now available for

Developed by a cross-industry group including Red Hat,
IBM and Intel, OpenStack runs by a strict six-month release cycle.
Previous release ‘Folsom’ was considered by many to be the first
production-ready version – though it has a long way to go before it
achieves widespread adoption.

Many of the changes introduced in
increase its scalability closer to the target of 60
million virtual machines, executive director Jonathan Bryce

told The Register

Within the Compute component, which manages VM
instances, Grizzly adds “Cells” to manage distributed clusters and
a “NoDB” architecture to reduce OpenStack’s reliance on a central

Quotas for Object Storage environments can be now set
to automatically control growth, while the second full release of
Block Storage adds an “intelligent scheduler” that can be
configured to optimise for performance efficiency or
cost-effectiveness. The web-based dashboard also now includes
control of networking and load balancing, and has been translated
into more languages.

The grizzly details

If it’s any indication of how much work has been
carried out since the last release, Grizzly clocks up at 820,000
lines of code – up from Folsom by 35%.

According to
software development analytics company Bitergia
– who break
down each OpenStack release by company – Red Hat have contributed
racked up 1854 commits – twice the number of second-largest
contributor (and project founder) Rackspace.

However, OpenStack’s community remains diverse, with
517 individuals and more than 50 companies contributing to Grizzly.
Red Hat’s contributions to OpenStack, though large, still only make
up 20% of the total codebase.

This active community is generally seen as OpenStack’s
edge against older rival CloudStack, but with the latter
now a fully-fledged Apache project
, competition between the two
may begin to hot up.

OpenStack has still yet to prove itself as a truly
practical solution, despite being run in production by Rackspace.
Last month, OpenStack consultants Mirantis caused controversy by
claiming that PayPal may replace their existing VMware-powered
operation with OpenStack – claims which were
quickly refuted by PayPal
