We performed a comparison between RHEV and VMware VSphere based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, VMware VSphere got better user reviews. One major difference between the two solutions is that users say that RHEV’s scalability is not great.
"The solution has a good licensing module."
"This solution is very stable. Much more so than similar products."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"It is a stable solution...It is a scalable solution."
"The solution makes migration easy."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"One of the most valuable features of this solution is the popularity of the OS."
"VMware vSphere helps us in not wasting resources like we did when we were using physical servers. It changed our whole environment."
"The tool comes with scale-out capabilities. Deploying new infrastructure became much quicker, saving significant time previously spent sourcing hardware for each installation. It also has the ability to downscale on rack spaces, reducing the number of rack units needed to accommodate our servers."
"The solution is very straightforward to implement."
"The interface is good."
"The solution is scalable."
"The VMware community is always there and it is a valuable resource."
"VMware's high availability which supports our SLA, VMware on the fly features like LUN expansion, P2V and API integrations are the most valuable features."
"Production people can quickly reboot the server with ESXi Quick Boot."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"In comparison to VMware, this solution isn't as stable. We're testing it right now, and we're not trusting the stability of the product."
"While everything needs improvement in some way, I have no specifics."
"The UI should be more interactive with additional features."
"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 documentation is not as good as it should be."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"The solution has a very small lifecycle."
"In future releases, I would like to see less pricing. The license can be improved."
"The price could be better."
"These days we have an environment where we are often using clouds as well. A solution that would be a little more cloud-aware would be really helpful. I know there is a product from VMware that is more specifically for the cloud, but it would be nice if VMware Cloud Manager would be cloud-aware. It would simplify certain processes."
"When I use VMware and Citrix there are conflicts."
"It would be nice if it had auto-scaling, no need to select CPU or select database size. Let it auto-scale, let it use the features that VMware has, instead of having to preselect."
"The technical support is poor. We are in Australia, but we do not have the same level of support as the US and Europe."
"I'd like to get rid of the Flash Client. There are still some things we need to go in there and use it for, some plugins and other things aren't supported in the HTML5."
"It could use a smaller learning curve."
