Featured Reviews

FOURES Jean-Philippe - PeerSpot reviewer
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.
Amar Sorro - PeerSpot reviewer
Manage and monitor crucial banking operations with deep logging and efficient alerting
The most valuable features of VMware Aria Operations include its excellent monitoring capabilities. It allows me to perform deep monitoring and logging of the entire environment, providing a quick alarm and warning system through email. These features help me in efficiently managing virtual machines. The solution also offers easy access to VMware KB articles for problem resolution, ensuring quick access to troubleshooting information.

Quotes from Members

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

Pros

"The solution provides templates for configurations that can easily be exchanged to VMs."
"With a single click, we could set things up and initiate them."
"It is quite easy to deploy."
"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."
"OpenNebula is lightweight, stable, and easy to customize."
"It makes maintenance very easy and stress-free for our teams."
"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."
"I'd like to see the streamlining of more wizards, more tasks that are canned. And it would also be good to see some more features around building the Blueprints, just to make it a little easier."
"The last two versions of it, we've gone with the integrated, high-availability built into the product, and that was a welcome change for us. It's even better now not having to have any kind of load-balancer in front of it..."
"Their technical support is good. We haven't had too much use for them."
"I've found vROps' predictive actions, monitoring, reporting, and provisioning features to be useful."
"Its job automation features and reporting capabilities are unique and valuable."
"The visibility it provides from apps to infrastructure and across multiple clouds is also great because it's a tool that aggregates a lot of data, both on-premises and in the cloud. It aggregates everything in one tool, which helps you to analyze the performance and the capacity of the infrastructure."
"It allows for a bit more transparency regarding consumption and it also helps us plan ahead."
"The dashboards are great. You can quickly see things at a glance without having to dig through a lot of data."
 

Cons

"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."
"The UI, monitoring, and alerting could benefit from further improvements."
"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."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"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."
"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."
"If the cost of the license could be cheaper, it would be good."
"I haven't had to use technical support for this version but I have had to use them in the past with other versions. There have been some challenges with them. It's hard to get through to the right person and resolving issues in previous versions was hard."
"The solution can improve by offering more flexible integration with other platforms or products, such as Hyper-V or Azure. Not everyone uses VMware. It would be beneficial to have a more open-source concept for integration, creating more visibility across multiple clouds."
"We're on the 6.0 version, so it does lack a little bit of that intuitiveness. You have to have some experience with VMware to get around inside of it."
"I want vROps to have wider compatibility with older hardware. In this country, many companies have older hardware, so sometimes we can't support all the newest features."
"The tool should have an easy workflow with some guided steps to make it simpler from the customer's perspective."
"Where the product could improve would be the UI."
"They should make it easier to find those granular things that you're always looking for. You're always running into a situation where you want to use the tool to figure out a problem, but the amount of effort needed to delve into vROps and find the exact metric you're looking for is always so difficult."
 

Pricing and Cost Advice

"VRA is very expensive but OpenNebula is free."
"The solution is open source so is free."
"OpenNebula gives good value for money."
"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."
"We use the Community Edition, rather than the Enterprise Edition."
"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."
"VMware support is very costly compared to other organizations' support. When you purchase a VMware product, such as vSphere or vROps, the license is perpetual, but you also have to purchase the support service for a number of years. The support service pricing is very high compared to the license, and compared to competitive vendors."
"The solution is costly."
"The pricing is a little bit expensive. Licensing is an issue because there are always changes, and by that I mean cost increases. And that's not only for vROps but for VMware, vSphere, and all the products that are involved."
"Bundle it in with your license rather than buying it as a separate product. It saves a lot of money that way."
"The predictive analysis of the infrastructure helps our customers to reduce downtime and improve capacity planning. Issues are fixed faster with vROps."
"The licensing model is annual. Compared to the price of other products, VMware vRealize Operations (vROps) is a bit on the high side. If it could be cheaper, it would be good."
"We would like to build custom dashboards in the standard license. Right now, this is available in the enterprise license, not the standard license."
"The value that we get from vROps is okay. It could be cheaper."
