Featured OpenNebula reviews

FOURES Jean-Philippe

Products Manager at a tech services company with 501-1,000 employees

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.

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.

Principal DevOps Engineer at Guavus

I would like to see OpenNebula add more integration with REST API. XML-RPC API is good, but it becomes a pain to form a resting output. The pathway and prediction and all those things can be tricky. 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.

Pricing

"OpenNebula gives good value for money."
"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."
"The solution is open source so is free."
