Featured OpenNebula reviews

Andrea Andrea

CTO at BE.iT SA

Setting up OpenNebula is complex. It’s not a plug-and-play solution, so you have to download the right version and compile it yourself. As it is open source, it requires some work. OpenNebula needs ongoing management and it is not an easy solution which can be installed and kept to work on its own.

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.

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."
