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.

Used to manage Kubernetes infrastructure, but it doesn't have support from OCI

Spot Ocean is deployed on the cloud in our organization. I would recommend the solution to other users. You need to have an experience with Kubernetes, or else this product is of no use. It is not difficult to learn to use Spot Ocean. Overall, I rate the solution a seven out of ten.

Quotes from Members

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

Pros

"OpenNebula has very good integration with SAP Storage."

"It is quite easy to deploy."

"It's easy to integrate OpenNebula with our IT systems."

"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."

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

"With a single click, we could set things up and initiate them."

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

More OpenNebula pros

"The solution offers both block access and file access, making it a nice solution for customers."

"The solution helps us to manage and scale automatically whenever there is a limit to the increase in the application workflow."

Cons

"The storage feature that they have is a bit confusing."

"There are no payment gateways in OpenNebula."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

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

"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."

"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."

"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."

More OpenNebula cons

"The solution doesn't have support from OCI, and it should start working to onboard OCI."

"There are no particular areas for improvement I can identify."

Pricing and Cost Advice

"OpenNebula gives good value for money."

"VRA is very expensive but OpenNebula is free."

"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."

"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."

"The solution is open source so is free."
