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 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."
"The solution makes migration easy."
"It is a scalable solution."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"Red Hat is the most stable system."
"Stability and speed are the most valuable aspects."
"Customers are moving to open source and Red Hat is the leader in this particular space. I think customers feel more confident running Red Hat Virtualization than VMware."
"The solution is stable."
"The interface is good."
"Stability and scalability are the most valuable features of this solution."
"It makes managing your virtual servers easier and more centralized."
"The initial setup is very simple."
"It's a very nice tool to be able to reduce your footprint, consolidate servers, and accumulate several servers in a high-density configuration."
"We are able to increase the density of the virtualized servers and, with the increased density we have a lot of page sharing as well as memory sharing."
"It gives us the ability to be running over 250+ VMs on five physical hosts and in various flavours of guest OSs."
"We are able to patch our hosts during production hours with the ability to keep services running."
"A few features of the product do not work as well as those in VMware."
"The support is tricky in a few places. We're facing some challenges within Malaysia where we don't really have the system integrators available who can provide extended support. When we need personnel on-site, we can't get them."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"There is not any proper documentation on the site to reference."
"The solution should be made more user-friendly."
"This solution could be more secure."
"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."
"The solution has a very small lifecycle."
"The only concern that I have with VMware is the support. It is very limited and can be better."
"They should improve their storage management part. vSphere has its own file system type, called VMSS, and that file system doesn't report on proper data usage or things like that. There are certain loopholes wherein it sometimes shows you erroneous data. Again, their VMSS file system, their data storage management system, and its reporting must be improved a lot."
"Technical support could be faster in terms of response times."
"Two improvements that I would like to see are higher resolution console modes for guests and easier switching between consoles."
"This solution should have a better backup policy. Furthermore, there should be an ability to expose the universal machine. In the current version, you need to shutdown and use an offline virtual machine to backup."
"It could use a smaller learning curve."
"I'm using vSphere at a high level. Sometimes, I find it challenging to integrate different networks, but I think it's just my lack of knowledge."
"The one area where I would love to see an improvement is the HTML5 client. It's great, but it could get better."
