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 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."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula has very good integration with SAP Storage."
"With a single click, we could set things up and initiate them."
"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."
"The service feature appeals most to us, thus it is the most valuable."
"It makes maintenance very easy and stress-free for our teams."
"It allows us to see the VM, our cluster utilization - the cluster level is what I work on the most. I'm able to see how much is being utilized, the rate of resource utilization, and when it will actually run out."
"It has increased the speed of VM deployment. A normal server request would come in, it could take anywhere from three to four days to deploy and now within 15 minutes they can click and have something up and running. IT support for developers is nice as well because they are able to manage the environment themselves."
"From a manager's standpoint it's the dashboards. To be able to quickly and easily see what's going on in our environment, from my perspective."
"We have all the information that we need in one place and don't have to search for our monitoring tools everywhere."
"The most valuable feature is the seamless integration with the vSphere Client and being able to go quickly back and forth between an incident within the vSphere interface and the actual drilling into it within vROps, to identify problems."
"Can be customized according to customer requirements."
"The most valuable features are the health tree and the alerts that tell us what's going on from a glance at the dashboard. As far as showing us where the problems are, what's useful is that it gives us suggested solutions to fix them, so that's helpful."
"It allows me to see how my entire infrastructure is performing in a simplified manner."
 

Cons

"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."
"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 should add more features like object storage."
"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."
"There are no payment gateways in OpenNebula."
"The UI, monitoring, and alerting could benefit from further improvements."
"Hosting platforms are limited so the deployment process needs improvement."
"The solution could improve by having more APIs, customized alerts, and documentation."
"From a personal perspective, I would like it made clearer what options are available in the suite that the customer is not using."
"We would like the return of the additional partner marketplaces, like DataCore. My customers miss the integration to DataCore."
"We have an Enterprise Plus license, so there's a long list of stuff that you get with the Enterprise Plus license, and I'd like to see a better integration of all the vRealize components."
"Technical support is good, once you pass the first level."
"Account management strategy is an area of concern where improvements are needed."
"One area that needs improvement is the solution's connectivity and integration with other products, such as IBM and Huawei servers and storage."
"I would like to have more documentation, in the form of knowledge bases, that better explain the technology, related products, and what the capabilities are."
 

Pricing and Cost Advice

"VRA is very expensive but OpenNebula 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."
"The solution is open source so 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."
"We use the Community Edition, rather than the Enterprise Edition."
"The optimization is a huge return on investment alone."
"The initial costs are a bit on the higher side but the licensing is flexible."
"It is an affordable solution that doesn't require any additional costs."
"The solution has helped to reduce the time to troubleshoot issues."
"We have definitely seen ROI by removing unnecessary servers and VMs. By having vROps as an assistant when it comes to monitoring and managing resources, it has helped us a lot with cost savings and managing expenses."
"The pricing: It's expensive."
"The price of the solution is expensive."
"The solution is slightly expensive."
