Executive SummaryUpdated on Dec 17, 2024

Cisco UCS Director and OpenNebula are both strong contenders in the cloud management platform space. Cisco UCS Director shows a notable advantage in support and integration, particularly for enterprises with existing Cisco infrastructures. Conversely, OpenNebula's flexibility and open-source nature offer a unique appeal for businesses seeking customization opportunities.

Features: Cisco UCS Director includes comprehensive automation and orchestration workflows, seamless integration with Cisco hardware, and extensive multi-cloud management capabilities. OpenNebula offers multi-hypervisor support, an intuitive open-source framework, and hybrid cloud functionalities.

Good multi-cloud management capability, but third-party and legacy integration needs improvement

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. I feel that more development or a more integrated road map should be set up so that it becomes a common platform for any infrastructure. In the next release of this solution, I would like to see changes in the navigation controls of UCS Director. That would be helpful. Modifying the icons that are available for use, as well as virtualization aspects.

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.

Pricing and Cost Advice

"I would rate the product's pricing an eight out of ten."

"VRA is very expensive but OpenNebula is free."

"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."

"The solution is open source so is free."

"OpenNebula gives good value for money."
