Good interface, and an easy initial setup with good community support on the free version

The customization should be improved. We should be able to diversify the machine for AWS. When we get involved with that right now, it becomes very bad. Some areas of configuration didn't work for us. The solution should offer more speed and should be able to stabilize the database environment. We've tried to do this, but it hasn't been solid. Sometimes it works, sometimes it doesn't. If we want to do an interceptor, what we need is a really high level of TT programming or a specific configuration to be able to scale it out. It works to some extent, but it's not strong. When it does not implement in our center we have to go and manually fix it. The solution should be able to better scale the number of users, especially when you're using the cloud. The solution should extend better into the Microsoft community and companies should be able to run it on Azure Cloud.

Robust with great CLI tools and UI

I've found OpenNebula upgrades to be more complex than those of some of the competitors and the support to be mediocre. I would also like to see more and better ancillary tools related to OpenNebula, for example, more robust tools for backups, user support, etc. The support knows their software stack reasonably well. However, OpenNebula depends on so many open-source projects that they lack expertise. As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable aspect of the solution is the interface on the console."

"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."

"The solution provides templates for configurations that can easily be exchanged to VMs."

"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."

"It makes maintenance very easy and stress-free for our teams."

"The live migration feature has been great and is something we use very often."

"I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."

"The most valuable feature of OpenNebula is that it scales very well."

"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."

More OpenNebula pros

Cons

"The customization should be improved."

"Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing."

"They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work."

"It should have a simple REST API like most other tools. It's the industry standard format. An XML-RPC API gives you an XML document that you have to convert and then do something with that. REST API endpoint provides outputs in a JSON document. I would also like to see support for user data or heat templates, which OpenStack offers, but OpenNebula doesn't have this yet."

"Hosting platforms are limited so the deployment process needs improvement."

"The UI, monitoring, and alerting could benefit from further improvements."

"There are no payment gateways in OpenNebula."

"They should add more features like object storage."

"The protocol for clusterization is rough and doesn't work well."

Pricing and Cost Advice

Information not available

"VRA is very expensive but OpenNebula is free."

"The licensing for OpenNebula used to be free, but now it's no longer free. A customer contacted me asking to move to another provider because of the changes in the licensing terms for OpenNebula. I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

"OpenNebula gives good value for money."

"We use the Community Edition, rather than the Enterprise Edition."

"The solution is open source so is free."

"OpenNebuoa has recently come up with a new subscription model that is economical and a lot of new customers are choosing this as it is an easy subscription model."
