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."
"This solution is very stable. Much more so than similar products."
"It is a stable solution...It is a scalable solution."
"The solution is a great all-round product. The virtualization is especially good."
"What they provide is way beyond the essential requirements of customers."
"It's a scalable solution."
"There aren't any bugs on the solution."
"RHEV’s cost is much less compared to VMware."
"vMotion is one of the most useful features, which helps to provide both flexibility and High Availability. With new versions of vSphere and vCenter, it is still improving (e.g., vMotion across vCenter Servers and virtual switches)."
"Valuable features really depend on different projects. We are using the traditional infrastructure based on VMware vSphere. We are also using the high availability (HA) and Distributed Switch features to extend our network and switch between different hosts. The VMotion and SVMotion features are very essential for us to relocate the storage of virtual machines to different storage or vSANs. We are using VMotion and SVMotion features several times of the day. We are also using another VMware product to replicate a lot of solutions to a second replication site."
"As an end-user, I would say it has allowed us to have the flexibility of moving around our workloads on different machines, and not having to worry if anything is down."
"The speed of the solution is excellent."
"It has allowed us to be more resilient to infrastructure and hardware failure, reduced hardware costs, and decreased recovery time from failures."
"The most valuable features are its flexibility and the ability to move workload."
"For me, the most valuable feature would be the EVC, but EVC has been changed to be per-VM which makes it possible for us to migrate the VMs to cloud and not take into account what hardware they're running on. Also, a big improvement from the previous version is that I'm now able to schedule backup for the VCSA. That is, in my opinion, a huge improvement. The last thing that I think is really great is, I'm not able to boot the OS and not the entire server. That's going to save me a lot of time."
"Technical support is helpful and always available."
"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."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"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 could use network virtualization."
"A few features of the product do not work as well as those in VMware."
"The UI should be more interactive with additional features."
"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 documentation is not as good as it should be."
"It is expensive."
"I would like more Amazon stuff inside of VMware."
"Archiving, exporting, and backing up need to be improved for this solution, because they're slower than expected."
"VMware vSphere could be more secure and well-known to everyone."
"In the last couple of years, the breaking apart of specific added benefits and charging license upcharges for them. That would be the only negative thing that I have to say: As a large consumer of the Hypervisor, we have a hard time justifying the cost of utilizing the extra products, especially when it's a couple of grand here and there, a couple of hundred dollars here and there. It's hard for an IT administrator or an architect to sell to upper management. When they're seeing so much ROI from the Hypervisor, it's hard to show them that there is extra value in the additional products that can be tied on top."
"In terms of what could be improved, we do face some bugs when cloning the virtual machine - it fails sometimes."
"The technical support is not too bad, but not the best."
"The installation can take a long time, they need to improve on the simplicity and length of the installation."
