Worked right the first time out-of-the-box; we were provisioning to AWS within 10 minutes
Ironically, most of the features that we might have wanted to see were already introduced in the product announcement today, from what we saw in the beta, which was kind of cool. You can't come to market unless you have Azure support, and Azure was all over every slide we saw, so that was pretty cool. A couple of things that I did see, there are a couple of security features that need to be enhanced. It is way too easy to provision a VM onto a public cloud, wide open to everybody. So, there are a couple of issues there. We are obviously going to talk with the product teams and the architects about some of those things; a handful of things here and there. Most of the things we were looking for were already included. Things that we had requested a month ago, we are now seeing them here: Azure Stack integration and the OneView integration. These were the things we were saying, "Hey, if these were there, it would be really cool. We could use this." All of a sudden, "Oh hey, guess what is going to be at launch?" I am very eager to get my hands on the next version of this product, and to see what may or may not be missing.

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.

Quotes from Members

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

Pros

"OneSphere being a SaaS platform, you do not have to deal with those issues, it is in quickly and you can begin utilizing it right away."
"With all the time and investment in all the competitive products, still it makes them not even a competitor anymore, with how this works."
"It's easy to integrate OpenNebula with our IT systems."
"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."
"It makes maintenance very easy and stress-free for our teams."
"The most valuable feature of OpenNebula is that it scales very well."
"It has enabled us to decrease the optics by around 55 to 60%."
"The live migration feature has been great and is something we use very often."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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."
 

Cons

"A couple of things that I did see, there are a couple of security features that need to be enhanced."
"We are looking to be able to set a hard budget for the workspaces or projects."
"The protocol for clusterization is rough and doesn't work well."
"Template management also needs improvement in OpenNebula because it's inferior right now."
"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."
"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."
"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."
"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."
"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."
"I would like to see OpenNebula add more integration with REST API. XML-RPC API is good, but it becomes a pain to form a resting output."
 

Pricing and Cost Advice

Information not available
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"VRA is very expensive but OpenNebula is free."
"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."
