Hi,<br><br>In our web you can read about the generic benefits of a cloud management tool [1], the main advantages of OpenNebula [2], and a list of low-level features [3] for the upcomming 3.0 release (currently you can test the beta release [4]).<br>
<br>Is it worth to install OpenNebula? I'd say it depends on your scenario.<br>OpenNebula will prove useful if you need to manage more than one hypervisor, avoiding vendor lock-in. Another big benefit is that being fully open-source, you will be able to customize and tweak every small aspect of you cloud.<br>

Thank you Steffen for your answer.<br>
<br>
As I said, the prime intention is to construct a private cloud to provide SaaS to our clients. C12G will be necessary if we carry on the project , but just in its final phase.<br>
<br>
I thought using Opennebula I could, i.e. create a virtual machine that uses RAM from 2 physical hosts, but as far as I read that's not possible.<br>
<br>
Of course, the first step will be to create the private cloud in a test environment and perform a lot of tests before provide the SaaS to our clients. But what I was wondering is what are the main features of Opennebula that will be helpful in that process. One of them could be the centralitation of the virtual machines management, but I think that could be achive also with other products like Xen, which I've never used just read some features...<br>
<br>
I mean that introducing Opennebula in our architecture involves complicate it, so it must offer some advantatges that make it worth, and are those advantages that I'm trying to find out.<br>
<br>
In other words, what's the advantage of using Opennebula in a vmware or xen environment when these products have their own management consoles...? How could I justify to my boss the investment, in hours and support (c12g), to use Opennebula?<br>
<br>
Surely I ask these questions because I'm not sure what is or what it involves having a private cloud...<br>
<br>
Thank you,<br>

What for ? Unless you lay out the use case, the answers<br>
can only point into the blue!<br>
<br>

basically yes.<br>

Depending on your needs, you might consider<br>
the professional C12G support. On our smallish<br>
cluster for research related simulations we don't need it,<br>
but if some business relies on it, you might be better off<br>
with some professionals for support cases.<br>
<br>
Yours,<br>
