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.
"It is very stable."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"The solution is a great all-round product. The virtualization is especially good."
"RHEV’s cost is much less compared to VMware."
"Red Hat is the most stable system."
"It's a scalable solution."
"It is a stable solution...It is a scalable solution."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"Using vSphere we have virtualized over one thousand servers and this gave us management, cost and datacenter space advantages."
"The product offers good stability."
"The scalability has been good."
"From the interface, you see how much CPU utilization and RAM utilization that each one of those hosts is giving you. You can tell ahead of time when you need to start expanding the environment. And with VMotion, you expand the environment and then let DRS have at it and walk away."
"VMware vSphere helps us in not wasting resources like we did when we were using physical servers. It changed our whole environment."
"Some of the most valuable features are: the ability to Snapshot so that when we do updates we have a layer of protection for simplified rollback; the replication that we can leverage for data center failures and data center downtime; the ease of migrating workloads from physical device to physical device for maintenance that we have to do on physical servers."
"In the past, we struggled with VM encryption. We couldn't encrypt the virtual machines with older versions of vSphere without some kind of third-party tool. Now, with 6.7, it's all in the application itself, in vSphere. We no longer have to procure additional products to meet that requirement. We can just do it on the fly, and pass our audit with no issues."
"The solution has high availability."
"While everything needs improvement in some way, I have no specifics."
"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."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"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."
"There is not any proper documentation on the site to reference."
"The documentation is not as good as it should be."
"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."
"The latest version of the solution has a few bugs."
"As we continue to push mission-critical workloads into vSphere, and those workloads are not readily protected at the application layer for availability, continuing to increase the size limitations on FT-protected VMs would be a great advance."
"I feel that the scalability of the solution should be improved."
"As we introduce the DevOps culture, we need to make sure that the principles and tools used to support this approach can be easily integrated and interoperated with the vSphere environment with no (or less) redundancy in tools and functionality."
"Here in Egypt, we would like everything free. So if you give us the license for free, we would be thrilled."
"The cost could always be lower."
"The solution is stable. However, it could improve by being more secure."
"We've been using vSphere on Windows 7, and it had less fluff associated with ThinApp. Currently, with Windows 10 version that we have, it adds a lot of bulk to ThinApp. We have offices spanning across Canada from the east coast to the west coast. A ThinApp that is roughly around 400 MB in size would take minutes to open up. With Windows 7, the same ThinApp used to be close to 75 to 80 MB in size. So, I'm really not happy with the extra fluff that is bundled in Windows 10. It really messes things up for us at times."
