Thomas Bennett

Manager, DevOps System Engineering team at MX

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.

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 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.

I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

OpenNebula Reviews Summary
Author info	Rating	Review Summary
CTO at Encha	3.5	I use OpenNebula for NodeWeaver's GUI due to its scalability. However, its template system needs improvement, and the lack of payment gateways made me reconsider. I switched from OpenStack, which had issues with plugin compatibility and version control.
Manager, DevOps System Engineering team at MX	4.0	We run our SaaS platform on OpenNebula VMs in colocation data centers, leveraging its API, SDK, and custom modules for automation. While useful, upgrades are complex, support is mediocre, and pricing isn't intuitive, affecting our overall experience.
Products Manager at a tech services company with 501-1,000 employees	4.5	OpenNebula is central to our cloud services, efficiently managing both shared and dedicated virtual resources. Its cluster management and VXLAN support are highly valued, yet improvements are needed in API performance. We achieve significant cost savings compared to VMware.
Principal DevOps Engineer at Guavus	4.0	No summary available
CTO at BE.iT SA	4.0	We transitioned from VMware to OpenNebula for cloud management due to its flexibility and ease of integration with our IT systems. While it's effective in managing virtual machines, the web interface and hardware integration need improvement. Overall, OpenNebula is a mature product.
System Architect at a tech services company with 51-200 employees	4.0	No summary available
Associate principal engineer at a tech vendor with 5,001-10,000 employees	4.0	No summary available
Senior System Integration Engineer at a tech consulting company with 5,001-10,000 employees	3.5	We used OpenNebula to host an application accessible to employees and partners, valuing its template creation for easy deployment and cost-effectiveness. Improvements are needed in their marketplace, customer support, and clearer storage management, especially compared to VMware.
