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 product is flexible and compact. It has a lot of features."
"Feature-wise, the solution helps one to add multiple environments in one place...It is a scalable product."
"Cisco UCS Director is straightforward to use, which we greatly appreciate."
"The main feature of this solution is the integration with all the Cisco solutions and other vendors."
"A product that really aids in systems management without complexity."
"This is a user-friendly solution that is very good and easy to use."
"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 solution provides templates for configurations that can easily be exchanged to VMs."
"OpenNebula is lightweight, stable, and easy to customize."
"The most valuable feature of OpenNebula is that it scales very well."
"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'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."
"OpenNebula has very good integration with SAP Storage."
 

Cons

"Normally, UCS Director is used primarily for orchestration, but when we look at a non-Cisco data infrastructure components, the UCS Director needs a bit more improvement in terms of integration with third-party systems and with existing older systems."
"The product could allow more programmatic opportunities through better development of the API."
"It is not easy to add or expand the product."
"Currently, Cisco UCS Director is unable to integrate with another product or with a server from another brand."
"There are a lot of bugs in the solution. This is an area in the solution that can be improved."
"The product's pricing needs to improve."
"There could be an improvement with the integration with the newest solutions from other vendors' technologies."
"The tool should be a lot more intuitive and make it easy for us to understand and migrate."
"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."
"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."
"Hosting platforms are limited so the deployment process needs improvement."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"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."
"The protocol for clusterization is rough and doesn't work well."
"They should add more features like object storage."
 

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."
"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."
"OpenNebula gives good value for money."
"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."
"VRA is very expensive but OpenNebula is free."
"We use the Community Edition, rather than the Enterprise Edition."
