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

"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."
"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."
"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."
"The most valuable feature of OpenNebula is that it scales very well."
"OpenNebula is lightweight, stable, and easy to customize."
"It is quite easy to deploy."
"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."
"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."
"vRealize has a very nice dashboard. It integrates well with other products such as those from Oracle."
"We receive an overview from the dashboard of what is happening in our environment."
"It has improved our time to deliver on systems for development workloads, and as we do that with our larger development platforms, they don't have to wait on us as infrastructure to spin those up, because they can just spin up what they need and get to work, giving us definite cost savings since a smaller workforce can take care of it in a timely manner."
"Probably, the most valuable feature is being able to see what's going on in my environment."
"It definitely has a better view and visibility for everything that's going on, and helps keep tabs and makes sure everything is running well."
"With this solution, we are able to see where problems are happening quickly and improve turnaround time, which matters to us."
"With our customized dashboards, we can target issues and attribute them to the correct team, so we can quickly pass them off to the relevant team rather than have to go around in circles and have everybody say, "Not us.""
"I like that we can see what amount of the CPU has been used and what's been handed out. We can see how we can bring the virtual machines in line with what actually has been used which has saved us cost."
 

Cons

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
"The storage feature that they have is a bit confusing."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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 protocol for clusterization is rough and doesn't work well."
"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."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"There are certain issues with capturing the information on vSphere application metrics. vROps doesn't clearly capture those metrics."
"I can't pinpoint any specific areas for improvement at the moment, though there is always room for better pricing, licensing options, and potential enhancements in the user interface or customization."
"When you are at your lowest, support is pretty bad. They ask you dumb questions but when you come to second and upper service desk, it is much easier and much better to talk to and resolve the issue."
"We have faced one problem when integrating with vRealize Log Insight, where the logs are not collected because the component drivers are not updated."
"I was involved in the initial setup. It wasn't straightforward."
"Cost is an issue on vROps. The Standard edition, for an organization our size, is just not useful at all."
"Not a ton of value yet, but I can see it on the fairly near horizon."
"Your range of use will be restricted by the license level you have chosen."
 

Pricing and Cost Advice

"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."
"VRA is very expensive but OpenNebula is free."
"We use the Community Edition, rather than the Enterprise Edition."
"The solution is open source so is free."
"We would like to build custom dashboards in the standard license. Right now, this is available in the enterprise license, not the standard license."
"It was cost effective, because it fixed our problems."
"We did an enterprise license agreement with our VMware partner and put this in our bundle. We tried it and loved it, so we use it now."
"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."
"As we continue to implement it across multiple environments, it reduces costs as well."
"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."
"I rate the solution's pricing a seven out of ten."
"The predictive analysis of the infrastructure helps our customers to reduce downtime and improve capacity planning. Issues are fixed faster with vROps."
