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."
"The solution makes migration easy."
"There aren't any bugs on the solution."
"What they provide is way beyond the essential requirements of customers."
"It is a stable solution...It is a scalable solution."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"Stability and speed are the most valuable aspects."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"VMware vSphere is easy to scale. We haven't had any problems scaling what we're scaling now."
"I think that the solution is perfect. It's the best on the market."
"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."
"I like the capability of vMotion, DRS, high availability, and resource distribution."
"The GUI is very simple to use."
"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."
"It cuts down on hardware costs by being able to virtualize multiple hardware and multiple machines on a single piece of hardware."
"You don't need too many people to manage the solution once it's up and running."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"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 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."
"While everything needs improvement in some way, I have no specifics."
"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."
"It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period."
"The availability of technical expertise with the solution may be limited in some areas."
"A few features of the product do not work as well as those in VMware."
"We stopped using a lot of cloud services. However, I see that VMware has integrated with Amazon Cloud. We will now to have to move everything to the cloud."
"The solution could improve by having more integration."
"Given that I've been using version seven, it seems that some of the bugs I faced during that version have already been addressed in subsequent updates. Although I haven't personally tested them yet, it appears that these issues have been resolved. In version seven, there was a problem with the network interface not responding due to certain configurations not being properly filtered. However, in version eight, this requirement has been minimized, so the mentioned bug is less likely to occur. Instead of solely addressing these fixes in newer versions, it might be beneficial for them to consider applying these improvements to the older versions as well. This approach could prevent users from feeling compelled to upgrade to version eight solely to avoid encountering the issue, and instead provide updates for version seven users."
"vSphere could perhaps be improved by more integration or better security."
"It's inherently complex. Operating a large virtual infrastructure is not an easy task for anyone."
"The challenge that we have is keeping the system up to date, as well as having the internal resources to maintain that platform. We're not an IT company, so it's challenging for us to keep the IT resources in-house."
"In future releases, I would like to see less pricing. The license can be improved."
"There was a time we lost the password for the ESXi and we had to do a hardware reset. At this point, we had to fill up the ESXi from the bottom up. I am not sure if there was another solution to this problem but it took a long time."
