A scalable and easy-to-deploy solution that allows users to manage multiple cloud resources
We use the product to manage an educational area here in Brazil The solution allows us to manage multiple cloud resources from one place. It has the ability to provide both IaaS and SaaS services. Managing SaaS is a valuable feature of the solution. The product must improve its stability and…
FOURES Jean-Philippe - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"The solution allows us to manage multiple cloud resources from one place."
"It is quite easy to deploy."
"I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."
"The live migration feature has been great and is something we use very often."
"OpenNebula is lightweight, stable, and easy to customize."
"OpenNebula has very good integration with SAP Storage."
"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 easy to deploy and manage compared to other solutions like OpenStack."
"It's easy to integrate OpenNebula with our IT systems."
 

Cons

"The product must improve its stability and speed."
"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."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"There are no payment gateways in OpenNebula."
"They should add more features like object storage."
"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."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"The UI, monitoring, and alerting could benefit from further improvements."
 

Pricing and Cost Advice

"The solution is a little expensive."
"VRA is very expensive but OpenNebula is free."
"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."
"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."
