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

"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."

"I'll definitely recommend OpenNebula because it's an open-source solution that's effortless to set up, and the total cost of ownership is low."

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

"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."

"OpenNebula has very good integration with SAP Storage."

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

"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."

"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

"From a metrics perspective, Zesty reduced our Kubernetes infrastructure spend by about 24% in the first six months, we also cut wasted storage costs by roughly 18% and improved saving plan utilization by around 12%, and on the operational side, we saved roughly 40 to 50 hours a month in manual cloud cost tuning."

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

"The turnkey aspect of Zesty is very valuable."

"I think Zesty is a really useful tool, it is really quick, it is really powerful, they are always improving it, and the customer service is flawless."

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

Cons

"Template management also needs improvement in OpenNebula because it's inferior right now."

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

"Hosting platforms are limited so the deployment process needs improvement."

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

"The protocol for clusterization is rough and doesn't work well."

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

"The protocol for clusterization is rough and doesn't work well."

"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."

More OpenNebula cons

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

"It would be really useful if Zesty had more code snippets that were easy to use, an easier library instead of their documentation, and something that provided an automated finish to insert code so it could give you code hints."

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

"The biggest area for improvement is still reporting depth."

Pricing and Cost Advice

"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."

"We use the Community Edition, rather than the Enterprise Edition."

"OpenNebula gives good value for money."

"VRA is very expensive but OpenNebula 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."

"The solution is open source so is free."

"The solution’s pricing is reasonable."
