Spot by Flexera provides automated cost optimization, advanced container and Kubernetes management, and intelligent autoscaling based on historical usage and pricing trends.

Room for Improvement: RHEV could improve by simplifying deployment complexity, enhancing third-party support, and expanding its open-source community engagement. Spot by Flexera could benefit from refining its user interface, increasing training resources for lower-experienced users, and expanding support for non-AWS cloud platforms.

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

"For any application that requires 100% uptime, 100% of data accessibility, I use these servers."

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

"It's a very good platform to build your virtual machines on and highly integrated with Red Hat itself and its satellites."

"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."

"Stability and speed are the most valuable aspects."

"The solution is easy for us to deal with when comes to application migration and has good compatibility with multiple components."

"The support for this solution is very good."

"They are so advanced today and so mature in what they do that they could easily give any top-notch industry leaders a run for their money."

More RHEV pros

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

"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."

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

"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."

"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."

Cons

"I heard that there are big differences between Red Hat eight and seven, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In term of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment."

"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."

"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."

"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."

"The UI should be more interactive with additional features."

"RHEV is not improving because it has been discontinued. It has been discontinued for years."

"We hope that Red Hat can produce a paradigm edition. We are looking for paradigm computing and paradigm storage. Its scalability can be improved. It is not easy to scale, and we hope that Red Hat can provide a more scalable system. They should also provide local service and support. Our customers are looking for a good software vendor to provide professional services."

"While everything needs improvement in some way, I have no specifics."

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."

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

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

"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."

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

Pricing and Cost Advice

"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."

"We buy a license for commercial use, and we also use the free editions."

"This is an open-source solution."

"The price of RHEV is high. It is an open-source solution, the price should be less. The price should not be on par with a solution, such as VMware. It's not more or equal to VMware, it's less, but the difference should be more substantial."

"We have to pay extra for vulnerability and fault tolerance."

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

"I believe we pay on a yearly basis."

"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."
