[one-users] OpenNebula vs. OpenStack: Two different views of the cloud

[Ignacio M. Llorente]

Dear community,

You may be interested in the invited article written by Carlo Daffara in
our blog about how OpenNebula compares with OpenStack... or what he answers
when someone asks him about “why they choose OpenNebula”...

http://opennebula.org/comparing-opennebula-and-openstack-two-different-views-on-the-cloud/

Thanks Carlo for the contribution!

Please do not forget that the OpenNebula community blog is available to
anyone interested in contributing experiences or use cases.

Re: [one-users] OpenNebula vs OpenStack

[Ignacio M. Llorente]

Thanks for your comments, we really appreciate your feedback, which
will be used to prepare the roadmap for the upcoming releases. There
are many people working on new unique innovative features in different
fields, such as high availability, fault tolerance and multi-tier
architectures. This innovation is being developed in collaboration
with several big organizations running very large scale
infrastructures. Some of these organizations are also allocating or
funding additional resources for development. This activity will
contribute to strengthen OpenNebula’s position as the leading and most
advanced technology to build cloud infrastructures.

It's always a little tricky to ask questions like this on mailinglists
of "competing" projects. Readers would have to detect whether it is a
trolling attempt or not. 

I cannot fathom, how many productive installations of OpenStack exist
today. That's why it might be very difficult to find people or
organisations that switched from OpenStack to OpenNebula.

At the same time, I'm interested in OpenStacks general architecture
(which I found after a few clicks under
http://nova.openstack.org/nova.concepts.html). 

What I like about Nova is, that it support UML from the beginning.
That's something I'd like to see in OpenNebula as well (or OpenVZ or
LXC for that matter). 
Furthermore, as an OpenNebula user I'm interested in Swift and whether
it can be integrated into OpenNebula as storage for VMs.

At the moment there seems to be no reason to change from OpenNebula to
OpenStack. And the only reason why Nasa and Rackspace have not
considered OpenNebula as their new platform might be the effort that
already went into the various components from which OpenStack was
"composed". 

I like, that OpenNebula doesn't want to impose certain constraints on
the users regarding his or her infrastructure. It integrates itself
very well into existing setups. As a good toolkit should do.

Kind regards,
Töns

Keith,

I cannot agree with you more.
There is NO virtual infrastructure manager more hackable than OpenNebula!

Re: [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.

Re: [one-users] OpenNebula vs OpenStack

[Christophe Hamerling - Petals Link]

Dear Ignacio,

As an active open source developer and supporter I have no doubt about the
quality and maturity of OpenNebula.
I was just wondering if any user as also experience with OpenStack and can
say more about why they switched from OpenStack to OpenNebula (and I really
hope the switch is this one).
BTW, this will be probably a good point to list somewhere the OpenNebula
'killer' features and why one should use OpenNebula instead of OpenStack.
It is something I wanted to ask last week at OW2 Conference but I think it
is quite complicated when both projects have representatives there... ;)

Re: [one-users] OpenNebula vs OpenStack

[Ignacio M. Llorente]

Dear Christophe,

We prepared a post [1] with a description of our position as
open-source project when OpenStack was announced in July. From a more
technical point of view, OpenNebula is a mature technology (we started
the development five years ago and did our first release almost three
years ago) that is used to manage very large scale clouds by some of
the world's leading telecom operators, hosting providers and compute
centers of leading research institutions. In our web site [2] we
provide details about the features for private, public and hybrid
cloud management, integration and production environments. We invite
you to compare these features with those provided by OpenStack and
evaluate which technology fits your requirements.

Regards

[one-users] OpenNebula vs OpenStack

[Christophe Hamerling - Petals Link]

Hi all,

I can find some comparisons between OpenNebula and Eucalyptus but nothing
between OpenNebula and OpenStack. Both looks quite close in term of feature
(from a light level view) but can someone give me details?

Thanks a lot,
Christophe
