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 main feature of this solution is the integration with all the Cisco solutions and other vendors."
"The most valuable feature of this solution is the fabric sharing."
"Feature-wise, the solution helps one to add multiple environments in one place...It is a scalable product."
"A product that really aids in systems management without complexity."
"Cisco's knowledge base is extensive."
"The reason we went with Cisco is that it comes at a very negligible cost as part of the BOQ. Compared to the competition's products, which are incredibly expensive, UCS Director is low-cost."
"The technical support for this solution is very good, at least in our region."
"The improvement for our organization has really been ease of use; we'd be a mess without the solution."
"The service feature appeals most to us, thus it is the most valuable."
"It makes maintenance very easy and stress-free for our teams."
"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 has given us tremendous knowledge about cloud computing and about Cloud Management platforms, commonly known as CMP."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"OpenNebula is lightweight, stable, and easy to customize."
"With a single click, we could set things up and initiate them."
"For our use case, we found the solution to be the best fit when dealing with infrastructure services."
 

Cons

"The product could allow more programmatic opportunities through better development of the API."
"The user interface could use improvement."
"The scalability of this solution needs to be improved because as it is now, you cannot scale the storage alone. Rather, you have to scale the storage and the compute together."
"There aren’t any areas of improvement that immediately come to mind."
"The solution could be improved is including a feature where I could do things programmatically versus having to create workarounds to get what I want to get done."
"There could be an improvement with the integration with the newest solutions from other vendors' technologies."
"The product's pricing needs to improve."
"The tool should be a lot more intuitive and make it easy for us to understand and migrate."
"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."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing."
"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 web interface could be better. It's not very difficult to use, but there's room for enhancement."
"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."
 

Pricing and Cost Advice

"The budget doesn’t work for the state and local governments."
"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."
"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."
"The cost of this solution is significant."
"The solution is open source so is free."
"OpenNebula gives good value for money."
"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."
"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."
