Reliable, simple to manage, and offers great technical support

Pros

"It makes maintenance very easy and stress-free for our teams."

Cons

It gives me the flexibility to define multiple views and data centers in one place.

Pros

"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. "

Cons

"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. "

An open-source platform that helps give customers increased control over their clusters

Pros

"It's easy to integrate OpenNebula with our IT systems."

Cons

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

Robust with great CLI tools and UI

Pros

"The live migration feature has been great and is something we use very often. "

Cons

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today. "

Lightweight, stable, and well-suited for end-users

Pros

"OpenNebula is lightweight, stable, and easy to customize."

Cons

"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."

Great integration with SAP Storage, is easy to use, has a good UI, and is very scalable

Pros
