AB
CTO at Encha
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.
AldoDomini - PeerSpot reviewer
Senior System Network Analyst at Net spa
Have faced limitations due to high costs but have maintained reliability over time
The primary issue is the pricing, which is very expensive for my company's budget. We cannot afford to pay such a large fee. We are not Microsoft or BMW; we are a small company. As a small company, I have no power to negotiate directly with VMware. Perhaps larger companies have more opportunity to contract directly with VMware, but I do not have that leverage. The only path I can follow is to change solutions. Net.spA is a company working in the field of waste management. We are not a technological company, so we do not have a large margin to justify purchasing and maintaining the VMware infrastructure at current costs.

Quotes from Members

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

Pros

"It is quite easy to deploy."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"The most valuable feature of OpenNebula is that it scales very well."
"OpenNebula freed my customer from doing the maintenance operations of the servers because now that can be done by his clients."
"The solution provides templates for configurations that can easily be exchanged to VMs."
"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."
"The service feature appeals most to us, thus it is the most valuable."
"It's easy to integrate OpenNebula with our IT systems."
"Monitoring is the most valuable feature for us. When our customers have a problem and we can monitor it in real time or evaluate the history of the problem."
"Being able to consolidate everything on similar hardware is really helpful, as opposed to trying to manage a bunch of hosts."
"I can go back a little bit, a week or a month, look at the history, to troubleshoot."
"Technical support is excellent; never had an issue with support with VMware."
"The biggest benefit is because it's an app developed by VMware and we are a VMware shop, they play well together."
"We have seen ROI because the time we take to solve problems has decreased a lot, so that is the way we give back to the company in the investment."
"Valuable features include trending of performance and capacity. Also, being able to dive into some more detailed analysis of performance metrics and compare them to a baseline of what's normal for particular time frames."
"We use it daily for troubleshooting; we use it for charting, for reports, and it's an awesome product with good performance."
 

Cons

"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."
"They should add more features like object storage."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"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."
"The UI, monitoring, and alerting could benefit from further improvements."
"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's not very good, because it's such a difficult product."
"We have used technical support sometimes. It could be a little bit challenging."
"vROps is, by its nature, a very complex product."
"A lot of the stuff we need assistance with is trying to get us help on our internal process of actually implementing stuff."
"They need to improve the capacity and infrastructure planning side of things. Also, I would like to see them integrate more stuff, with more detailed monitoring and different cloud providers."
"From a technical side, the product is very good. The challenging part is always the licensing."
"If I put on the hat of a client, I would say cost needs improvement. For clients with reasonable-sized infrastructure farms, you're looking at licensing at either per socket or per VM, and if you have an installation of any size, you're doing it per socket, and the per-socket licensing is a little heavy. Per VM license, if they have large numbers of VM, it is just not practical."
"Make it easier to get customized reports; right now, it's very difficult."
 

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."
"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."
"OpenNebula gives good value for money."
"We use the Community Edition, rather than the Enterprise Edition."
"We have seen good ROI results. It has made our lives easier."
"We would like to build custom dashboards in the standard license. Right now, this is available in the enterprise license, not the standard license."
"Pricing is good for us. We're non-profit so we get a break on that."
"We have seen huge ROI. It has certainly reduced troubleshooting."
"The predictive analysis of the infrastructure helps our customers to reduce downtime and improve capacity planning. Issues are fixed faster with vROps."
"Bundle it in with your license rather than buying it as a separate product. It saves a lot of money that way."
"If the VMs were trimmed, then we wouldn't have to buy as much software/hardware, and this means less licenses. While most of it is VMware licenses, which are relatively cheap, there are SQL licenses for Microsoft, and this is where we could start saving a lot of money."
"The license is a one time cost, and you pay for support on a yearly basis. It is a bit expensive, but if you consider the product support and its reliability, it's justifiable."
