Featured Reviews

FOURES Jean-Philippe - PeerSpot reviewer
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.
Jeffery Smith - PeerSpot reviewer
Effortless cost management with automated instance adjustment and helpful support
There are different resource types that we would like to leverage and get reserved instances for, such as RDS instances. Currently, no mechanism within Zesty allows this, but this may be due to AWS limitations. Another point is that Zesty needs to react to any changes AWS makes, but they have been proactive in their communication regarding material impacts.

Quotes from Members

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

Pros

"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."
"With a single click, we could set things up and initiate them."
"OpenNebula has very good integration with SAP Storage."
"OpenNebula is lightweight, stable, and easy to customize."
"The most valuable feature of OpenNebula is that it scales very well."
"It is quite easy to deploy."
"It's easy to integrate OpenNebula with our IT systems."
"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."
"The turnkey aspect of Zesty is very valuable."
"One of the reasons we decided to onboard Zesty was that it started supporting Windows instances."
 

Cons

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"Hosting platforms are limited so the deployment process needs improvement."
"The UI, monitoring, and alerting could benefit from further improvements."
"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."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"The storage feature that they have is a bit confusing."
"There are no payment gateways in OpenNebula."
"They should add more features like object storage."
"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."
 

Pricing and Cost Advice

"OpenNebula gives good value for money."
"The solution is open source so is free."
"We use the Community Edition, rather than the Enterprise Edition."
"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."
"VRA is very expensive but OpenNebula is free."
"The solution’s pricing is reasonable."
