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.

Karan Saini

Dev Ops Engineer at a construction company with 11-50 employees

Intelligent autoscaling has cut compute costs and now manages ephemeral workloads efficiently

I think overall Spot is quite good. The UI is powerful, but it can feel a bit dense for some new users. More guided onboarding would help teams adopt advanced features faster, and deeper insights into Kubernetes resource usage would be beneficial. Overall, it is a really good platform that is quite mature and stable. 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. Overall, I think Spot is a really good and stable tool.

Quotes from Members

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

Pros

"Performance and security are key advantages of RHEV."

"Stability and speed are the most valuable aspects."

"The solution is stable, there are no bugs or glitches, it doesn't crash or freeze, and it's reliable with good performance."

"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."

"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."

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

"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."

"The most valuable features of RHEV are all the tools, such as virtualization, management of cloud platforms, and integration of container environments. The solution has good compatibility between virtualization, content management, and cloud management. Having the full set of these tools is the advantage of it."

More RHEV pros

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

"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."

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

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

"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."

Cons

"The Administration of the Oracle database and the SAP ERP needs improvement."

"Load balancing not very efficient and fails to utilize and distribute network resources."

"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."

"Specifically, enhancements in managing virtual machine migrations, cloning, and the creation of different VMs could further optimize its functionality."

"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."

"RHEV can improve by keeping pace with new features and new enhancements. They should not be halted or delayed innovation because over the past quarter the enhancements have not been as fast as they have been previously."

"The initial setup is not simple or straightforward. It's very complex."

"Its scalability can be improved. It is not easy to scale, and we hope that Red Hat can provide a more scalable system."

More RHEV cons

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

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

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

Pricing and Cost Advice

"I believe we pay on a yearly basis."

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

"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."

"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."

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

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

"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 are using the free version of Red Hat."
