Reliable, simple to manage, and offers great technical support
The support of VXLAN fits with our network management. Thanks to this we can propose mixed solutions using virtual resources on OpenNebula and bare metal servers hosted in our facilities linked to each other on the sale network. This use case is very useful when some applications need bare metal power (Kubernetes workers, huge databases, AI models computations, et cetera). The cluster management is very useful for splitting our different clusters (mutual vs dedicated). We can manage deployments and capacity planning without pain. The API is also really simple and it helped us to develop the Terraform provider to manage OpenNebula like any other cloud infrastructure.

Pros

"Using InfrOS accelerates the process of migration planning and execution."
"I have observed improvements in CI/CD infrastructure optimization, designing AI-native workloads, exploring pricing alternatives, and forecasting."
"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."
"OpenNebula is lightweight, stable, and easy to customize."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"The service feature appeals most to us, thus it is the most valuable."
"It has enabled us to decrease the optics by around 55 to 60%."
"With a single click, we could set things up and initiate them."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."
 

Cons

"I would really like to have features that will help me analyze my usage on existing environments in the cloud and suggest architectural optimization improvements."
"There is room for improvement in the Github connection."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"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."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"There are no payment gateways in OpenNebula."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"An area for improvement in OpenNebula is the number of features it has. The solution doesn't have that many cloud features compared to other solutions. You'd say, "Okay, simplicity over a rich feature list?" Some say, "No, I need a big machine or a cloud interface for my customers to manage resources. I don't have to go and do it for them." Some people do it that way, and it works, but I'd like to improve the limited features in OpenNebula."
 

Pricing and Cost Advice

Information not available
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"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."
"VRA is very expensive but OpenNebula is free."
"The solution is open source so is free."
