Products Manager at a tech services company with 501-1,000 employees

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.

Global Head - DevOps and AIOps Startegist at a manufacturing company with 10,001+ employees

Enterprise governance has transformed how we automate terraform and manage policy as code

Scalr's UI and documentation could be more intuitive, especially for first-time users. During onboarding, I identified the need for improved documentation, especially for first-time users navigating various challenges, which has led to some struggles in finding the right answers in the documentation. Better search capabilities and more comprehensive documentation that is easy to navigate would be beneficial.

Quotes from Members

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

Pros

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

"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."

"It is quite easy to deploy."

"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."

"The service feature appeals most to us, thus it is the most valuable."

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

"The most valuable feature of OpenNebula is that it scales very well."

More OpenNebula pros

"Scalr has helped bring consistency and governance to our workflows, especially at scale, and it is a strong product."

Cons

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

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

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

"There are no payment gateways in OpenNebula."

"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."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

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

"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

"Scalr's UI and documentation could be more intuitive, especially for first-time users."

Pricing and Cost Advice

"The solution is open source so is free."

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

"VRA is very expensive but OpenNebula is free."

"OpenNebula gives good value for money."

"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."
