Executive SummaryUpdated on Jun 3, 2026

RHEV and Spot by Flexera are competing products in the virtualization and cloud optimization space. Spot by Flexera appears to have the advantage due to its advanced features and overall value proposition despite RHEV's favorable pricing and support advantages.

Mike Neuliep

Linux Systems Engineer at a tech services company with 10,001+ employees

Has supported virtualization projects in side jobs but has required workarounds due to lack of maintenance

In my opinion, the best features of RHEV are that it is a real hypervisor and it is free, so it performs better than VMware. I have used the live migration feature in the past with RHEV. There is a free clone of it that is based on the open source. Live migration is a nifty feature if your app is not highly available and you need to do maintenance on a machine. You can migrate the VM off of it, do your maintenance, and move it back when you are done. RHEV has a high availability architecture with a built-in monitoring feature where you could see machines other than the one you are operating on. I tend to implement high availability not so much in RHEV, but by using standard application high availability strategies. Red Hat has another product specifically for high availability.

Bruna Müller

License manager at a financial services firm with 10,001+ employees

Centralized asset data has transformed how we manage licenses and make cost-saving decisions

One problem that we faced using Spot by Flexera is that in certain servers, the data was not being updated correctly, and we had a certain delay. For example, someone was using a computer, and then this user received a new one. In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used. We had a couple of IT assets that were not being used, and we had this information in our internal servers, but Spot by Flexera was not able to update on time. We had to fix this information manually.

Quotes from Members

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

Pros

"It's a scalable solution."

"The initial setup is fairly straightforward and well-documented. The process is very similar to its competitors. The success of your setup depends on how well you plan."

"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."

"The biggest aspect for me is the disk usage, the virtual manager, and the deployment of machines."

"The platform is scalable, allowing for the installation of multiple nodes."

"In my opinion, the best features of RHEV are that it is a real hypervisor and it is free, so it performs better than VMware."

"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."

"The support for this solution is very good."

More RHEV pros

"The solution helps us to manage and scale automatically whenever there is a limit to the increase in the application workflow."

"By using Spot by Flexera across a year, we were able to save more than 500,000 euros."

"Spot has positively impacted our organization by automating cloud resource management, which has significantly cut costs and improved efficiency."

"The solution offers both block access and file access, making it a nice solution for customers."

"My compute costs have reduced, capacity and production output have increased, and my overhead for maintaining custom scripts or doing some of the tasks manually has been saved."

"Cost saving is the main benefit, and the manual effort required for reviewing and purchasing savings plans and other RIs is something we do not have to manage manually now, as we get automatic suggestions from Spot."

Cons

"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."

"You need to buy support from red hat and you need to renew support every year in order to keep getting support from red hat."

"Scalability depends on the applications. Red Hat by itself is not scalable."

"There are two things that I would like to see improvement in when it comes to Red Hat. First is the pricing and second is the support."

"A few features of the product do not work as well as those in VMware."

"When we do a direct comparison, then obviously VMware does better in terms of having Fault Tolerance and doing active disaster recovery and these kind of things. This is something that can be improved within Red Hat."

"My teammates and I often complain that VMware is well-documented and has a large community since it is the de facto standard. I would love to see better documentation and ease of use."

"I would love to see better documentation and ease of use."

More RHEV cons

"I chose a rating of nine because it may sometimes be a bit overwhelming for newcomers, and there are also a few areas in which the EKS Kubernetes level granularity is a little missing."

"I have not seen a return on investment yet."

"There are no particular areas for improvement I can identify."

"The solution doesn't have support from OCI, and it should start working to onboard OCI."

"One problem that we faced using Spot by Flexera is that in certain servers, the data was not being updated correctly, and we had a certain delay."

Pricing and Cost Advice

"RHEV offers pricing based on a per-physical-machine licensing model."

"I would say the price is acceptable."

"This product has a variety of licensing options available. However, the level of licensing, and therefore the cost of licensing, is dependent on the number of servers being utilized."

"It's a budget product as far as I'm concerned. It's way cheaper than any of its competitors. The only thing cheaper than Red Hat is that the people who take the Red Hat code clone it and then self-support it."

"Price-wise, RHEV is okay, in my opinion."

"The solution does not require licencing but a subscription is necessary, which is very affordable."

"I believe we pay on a yearly basis."

"Its price depends on the use cases."
