Hi Carlos,<div><br></div><div>Thanks for the additional comment. It's very delightful!</div><div><br></div><div>It is important that the product can fully leverage VMware licensed features or we cannot let vCenter goes away.</div>
<div><br></div><div>You have mentioned OpenNebula can be integrated on top of the vCenter. This sounds ideal because we won't lose the licensed features and gain additional cloud features from OpenNebula.</div><div><br>
</div><div>However, OpenNebula's documentation doesn't seem cover such topic. If I decide to give it a go, where's the best place I should start from?</div><div><br></div><div>Thanks</div><div>Derrick</div><div>

Hi Florian and all, thanks you for your comments.<br>
<br>Although Tino is the main VMware driver developer and he will be able to <br>provide more low-level details, let me say some words to clarify how<br>OpenNebula compares with VMware products. OpenNebula 2.2 can be<br>
used on top of VMware ESX and vCenter.<br>
<br>
- On top of ESX, OpenNebula provides all its features for<br>
public/private/hybrid cloud and virtualized data center management<br>
(<a href="http://opennebula.org/documentation:features" target="_blank">http://opennebula.org/documentation:features</a>)<br>
- On top of vCenter, OpenNebula can orchestrate several vCenter<br>
instances and offers cloud functionality not offered by vCenter:<br>
multi-tenancy, VM provisioning, cloud interfaces (EC2 and OCCI),<br>
public/hybrid cloud computing… so there are many benefits from using<br>
OpenNebula 2.2 on top of vCenter.<br>
<br>
vCloud Director is the new VMware product that on top of vCenter<br>
offers cloud functionality, mainly multi-tenancy and cloud API<br>
(vCloud). The functionality for grouping users and creating virtual<br>
data centers is something provided by vCloud that is not offered by<br>
OpenNebula 2.2. However, OpenNebula 3.0 (due in 2 weeks), and its<br>
powerful ACLs management, will offer much richer functionality for<br>
grouping users, creating projects, defining different levels of<br>
administration, managing virtual data centers….<br>
<br>
Summarizing, you can replace vCenter with OpenNebula if you want a<br>
more cost-effective, open, standard-based, flexible and hypervisor<br>
independent solution. However given that OpenNebula provides a<br>
management layer with hypervisor independence, there may be VMware<br>
specific functionality that is not leveraged by OpenNebula. You can<br>
also use OpenNebula on top of vCenter, but I think that in such a<br>
case, OpenNebula should have full control over vCenter and you should<br>
manage the cloud through the OpenNebula interfaces. Finally,<br>
OpenNebula 2.2 is not ready to replace vCloud Director, but this will<br>
be solved in OpenNebula 3.0.<br>
<br>
Please let us know if you need further information.<br><br>Best regards,<br>Carlos.<span style="border-collapse:collapse;color:rgb(136, 136, 136);font-family:arial, sans-serif;font-size:13px"><br>--<br>Carlos Martín, MSc<br>

Thanks Florian,<div><br></div><div>We are not very sensitive with downtime. Somehow we are lucky enough to receive vSphere Enterprise plus and vCenter licenses for free due to affinity with a university. And we benefit so much from vSphere's proprietary features.

<div>Hi Derrick,</div>
<div><br>
</div>
<div>from my past experience I can say, that OpenNebula in the current version is not ready to replace VMware vCenter. But, with OpenNebula 3.0 many of the missing features are implemented and as far as I could test them, OpenNebula seems to be a good / cost
efficient choice to replace vCenter. Integrating OpenNebula with vCenter and usage of ESX is possible, but from my point of view this is only valid as a migration path to replace it with a KVM or XEN infrastructure.</div>
<div><br>
</div>
<div>If you have a production setup where a downtime of your service costs a lot of money, then you're probably better off with vCenter and buying all their licenses. If you want to provide a cheap IaaS plattform, then OpenNebula 3.0 could be right for you.
BTW: From a recent comparison of OpenNebula 3.0 and the current version of OpenStack I got the impression that OpenNebula will be better suitable for IaaS environments. Especially the Sunstone Webinterface has more potential than the OpenStack webinterface.</div>
<div><br>
</div>
<div>Cheers,</div>
<div>Florian</div>

</div><div><div></div><div>
<div><br>
</div>
Hi guys,
<div><br>
</div>
<div>My institute is running a cloud platform which is VMware vSphere based with its Enterprise Plus license. We also have a vCenter server for managing the platform.</div>
<div><br>
</div>
<div>I have been seeking a way to allow me to automate the VM deployment process and contextualize the Linux VMs.</div>
<div><br>
</div>
<div>OpenNebula seems to be a solution. I have read through some documentations as well as the VMware Driver Addon guide. But I still not quite understand many basic aspects of OpenNebula, particularly:</div>
<div><br>
</div>
<div>1) What's the position for OpenNebula in a VMware based platform that vCenter already exists? </div>
<div>2) Our Enterprise Plus license gives us full features of the vSphere platform, work with the vCenter, does OpenNebula interact with those features as well?</div>
<div><br>
</div>
<div>I'd keen to hear from anyone who has the experience on this.</div>
<div><br>
</div>
<div>Thanks in advance.</div>
<div>Derrick</div></div></div>
