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.

A highly scalable solution that gives good value for money, but it does not have payment gateways
OpenNebula's templates are weak, and it could do something to make template creation a lot easier to use. The solution has a template for every single VM you create, which is not clever. You should be able to use a template for many different virtual machines. There are no payment gateways in OpenNebula.

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."
"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."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"The service feature appeals most to us, thus it is the most valuable."
"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 live migration feature has been great and is something we use very often."
"The most valuable feature of OpenNebula is that it scales very well."
"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's easy to integrate OpenNebula with our IT systems."
 

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."
"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."
"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"The UI, monitoring, and alerting could benefit from further improvements."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"Hosting platforms are limited so the deployment process needs improvement."
"They should add more features like object storage."
 

Pricing and Cost Advice

Information not available
"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 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."
"OpenNebula gives good value for money."
"We use the Community Edition, rather than the Enterprise Edition."
"The solution is open source so is free."
