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

"Cisco's knowledge base is extensive."
"Cisco UCS Director is straightforward to use, which we greatly appreciate."
"I can manage multiple workloads whether it's on AWS, Azure, or on-premises. They can be managed by using the UCS Director."
"Feature-wise, the solution helps one to add multiple environments in one place...It is a scalable product."
"I would recommend this solution to others because it simplifies a lot of tasks via orchestration."
"The improvement for our organization has really been ease of use; we'd be a mess without the solution."
"The product is flexible and compact. It has a lot of features."
"The technical support for this solution is very good, at least in our region."
"The live migration feature has been great and is something we use very often."
"OpenNebula is lightweight, stable, and easy to customize."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"It is quite easy to deploy."
"The service feature appeals most to us, thus it is the most valuable."
"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."
"It has enabled us to decrease the optics by around 55 to 60%."
 

Cons

"Currently, Cisco UCS Director is unable to integrate with another product or with a server from another brand."
"There aren’t any areas of improvement that immediately come to mind."
"The areas where this product can be improved are the integrations and the UI. These features are not as friendly compared to VMware products."
"We cannot depend on this solution to manage all of the data center's infrastructure."
"There are a lot of bugs in the solution. This is an area in the solution that can be improved."
"There could be an improvement with the integration with the newest solutions from other vendors' technologies."
"Simplifying the user interface would go a long way to making it more usable."
"It is not easy to add or expand the product."
"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."
"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 UI, monitoring, and alerting could benefit from further improvements."
"There are no payment gateways in OpenNebula."
"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."
"The storage feature that they have is a bit confusing."
"They should add more features like object storage."
 

Pricing and Cost Advice

"The budget doesn’t work for the state and local governments."
"The cost of this solution is significant."
"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing around five to six out of ten."
"I rate Cisco UCS Director's price a three out of ten. Cisco UCS Director is not an affordable product. With Cisco UCS Director, there is a need to pay an overall price, which consists of the product, software, and support."
"Cisco UCS Director is expensive...I rate the solution's pricing a three out of ten."
"I would rate the product's pricing an eight out of ten."
"VRA is very expensive but OpenNebula is free."
"OpenNebula gives good value for money."
"The solution is open source so 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."
"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."
