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.

Managing complex onboarding has been challenging but automated cost optimization delivers strong savings

Zesty is a good solution; however, the learning curve can be complex for new users without a solid tech background, posing a challenge in training and the initial setup process. I would deduct one point for this aspect since everything else is fine. A specific example of where the learning curve caused issues is when we introduced Zesty to our new development team, which struggled to understand the platform while working on a project related to AI and ML. Our system architects explained how Zesty works, but I believe a more proactive approach to training and foundational data could help teams be more self-sufficient and less reliant on internal support.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"With a single click, we could set things up and initiate them."

"The solution provides templates for configurations that can easily be exchanged to VMs."

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

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

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

"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."

"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."

"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."

More OpenNebula pros

"The turnkey aspect of Zesty is very valuable."

"One of the reasons we decided to onboard Zesty was that it started supporting Windows instances."

"Zesty has positively impacted our organization by providing a good return on investment, with a total reported percentage of savings around 40 to 50%."

Cons

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

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

"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."

"The storage feature that they have is a bit confusing."

"They should add more features like object storage."

"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."

"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 front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."

More OpenNebula cons

"There are different resource types that we would like to leverage and get reserved instances for, such as RDS instances."

"I would like to get RDS-reserved instances that I could buy and sell, but that's a limitation on AWS."

"Zesty is a good solution; however, the learning curve can be complex for new users without a solid tech background, posing a challenge in training and the initial setup process."

Pricing and Cost Advice

"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."

"OpenNebula gives good value for money."

"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’s pricing is reasonable."
