[one-users] OpenNebula vs OpenStack

[Keith Hudgins]

Nova (the part of OpenStack that compares with OpenNebula) is *very*
immature at the moment. It's a brand-spanking new project only a few months
old, and doesn't really do much at the moment. In the long run, it may
compare favorably with OpenNebula, but it will be at least 6 months before
Nova begins to catch up. I know a couple of people working on Nova, and
they're VERY good developers, so I have no doubt it will be a very nice
piece of software in the future. If you want to put it into production
today... don't. It's pre-alpha and not even close to feature-complete. You
can launch VMs from Nova, but not much more than that. There's currently not
any solid multi-user support, for example. It's worth tinkering with, for
sure, but not for production.

OpenNebula is mature, proven, and works pretty well. It's not as slick as
some of the commercial products available, but it's much more hackable
(seriously - I've said it before and it's still true - there is NO virtual
infrastructure manager more hackable than OpenNebula), and the community
ecosystem is complex and useful. From the ecosystem you can install a
graphical interface, alternate schedulers, and many install automation
tools.

If you want to look at more mature software to compare, Cloudstack (very
slick, use their reference architecture until you understand how the pieces
fall together), Eucalyptus (good luck! Ubuntu Enterprise Cloud is still the
only reliable, simple way to get this going), Ganeti (very interesting, DRBD
backing store, not intended for large scale though) are good comparison
examples to test. None of them work with the range of hypervisors or APIs
that OpenNebula does, but they may scratch a particular itch you have.
