OpenNebula is the core of our cloud offering. We propose virtual resources to our customers. We have several zones grouped into an OpenNebula Federation to serve more than 50 customers. Some customers use a global infrastructure with dedicated VMS running on shared hosts. Some customers with specific needs and more VMs are deployed on dedicated nodes. Only their VMs run on these nodes.
This very simple model is really appreciated by our valuable customers, it was very simple to set thanks to OpenNebula's cluster feature.

NodeWeaver's GUI is based on the OpenNebula platform, and I use OpenNebula to interface into the NodeWeaver product set.

We run on a SaaS platform with millions of end users; our entire platform runs on OpenNebula VMs in colocation data centers. At peak usage we had roughly 3000 individual virtual machines running, all VMs were Linux. Our company has built multiple independent OpenNebula clusters.  

We leverage the OpenNebula "cluster" features as well to segment different workloads and security requirements.  

We do use the web interface for small tasks, however, we mostly leverage the API, SDK, and custom-built Ansible modules to interact with the OpenNebula server.

We use OpenNebula to set up a virtual private cloud across several physical servers. It has an XML-RPC API that we automate via Python. You can connect it to VMware and run it over KVM. The latest version supports containers, but I haven't tried that. I mostly do KVM-based virtualization. I think the whole company is using it, so we have around 260 users. 

We are in the process of building a public cloud and we are using OpenNebula for its management. At the backend, we use ESXi 6.7, vCenter 6.7, and NSX. I believe that it's a really good combination for creating your cloud. We didn't choose the vCloud Director because of the license and we cannot pay for it. The reason is that we are in Iran, and we are faced with sanctions.

Our company recently completed a project for a customer where we used the solution for cloud management. Our team included four developers, one QA, and a technical manager. 

The customer desired to move from a private to an open or hybrid cloud platform for their lease management system. The customer had dealership and manufacturer showrooms on different systems, controls, and software. We built their systems with different operating systems, CPUs, and memory and constructed a system to manage those resources. 

We use the solution as a super user to provide administration for all users, systems, and upgrades. We can remotely provide users with credentials or install needed items into certain umbrellas. 

The solution prepares and automates workflow because it allows for template and VM creation, assignment of users to certain VMs, and administrative privileges.

We mainly use OpenNebula for automatically deploying Kubernetes clusters and replacing our (old) Proxmox infrastructure.                                           

We used to host an application that could help the organization. It helped all the employees and the partners access all our products which we had set up as a virtual lab in OpenNebula.

I've deployed OpenNebula a few times, primarily for public cloud hosting providers who want to get into the cloud business.

My company provides system integration services for different clients based on OpenNebula. I'm a systems architect. 

In my previous role at a system integration company, we used OpenNebula to deploy private clouds for our clients. My current company uses it for our own needs. 

We have been actually giving demonstrations and other things surrounding the solution. OpenNebula in these parts is not so well known. There are a lot of people who could be using it without our knowledge. We are trying to showcase it to big customers to show them how to create a private cloud using OpenNebula. It's a cloud management tool.

OpenNebula has better simplicity than vRA. It is designed perfectly for the end-user. OpenNebula has many features for the end-user in the private cloud and you can convert into the public web with some development. It's very user-friendly and very easy to use. We use it to provide the private cloud enterprise data center.

We have implemented it for internal purposes and more for learning.

Integrated with KVM and VMware Hypervisors and on meager resources, just to check whether it works or not. We started this approximately five years back and it worked flawlessly.

A YouTube video shows the details of our implementation.

This can be used as a private/hybrid cloud and there are many well-known organizations that are using OpenNebula. These include the European Space Agency (ESA), BBC, China Telecom, TransUnion, and Trivago.

OpenNebula can also be used for High-Performance Computing.
