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.
"Stability and speed are the most valuable aspects."
"It is a stable solution...It is a scalable solution."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"The solution is a great all-round product. The virtualization is especially good."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The solution has a good licensing module."
"This solution is very stable. Much more so than similar products."
"Valuable features include VHA, DRS, VMotion, and redundancy and failover; any DR situation."
"The solution saves cost."
"We can slide in new resources without any impact. We can do maintenance on our clusters without any impact to applications, and we have the flexibility of migrating those workloads to other data centers, when required, in the case of data center downtime."
"The ability to monitor resource utilization."
"The solution is scalable."
"The performance is efficient."
"One of the things I like with the web client, versus the thick client, is that we're able to access all the vCenters that we manage. With the thick client, you have to log in to one vCenter at a time."
"The tool provides 99.99% uptime."
"While everything needs improvement in some way, I have no specifics."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"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."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"The UI should be more interactive with additional features."
"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."
"The solution should be made more user-friendly."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"The initial setup could be better. It manages all the setups, but it's not very straightforward, and it takes time."
"The way that vSphere manages the alerts on the data machine is not easy to configure."
"The biggest problem in this solution is the incompatibility of some of the features with some of the drivers installed on servers. For example, if I want to install vSphere on an HPE server, the driver is really different from a Dell server or a Fujitsu server. I need to download different drivers and install them manually, which can be improved by VMware. They can offer a special image to match different servers. We face different problems when we install vSphere on an ESXi server and have different drivers on the storage. ESXi cannot detect different kinds of storage, and they should improve this. We updated our existing version to vSphere 7 in a private environment, but it seems that this version is not very stable. We are facing issues with restarting the host. In earlier versions, such as vSphere 6 or 6.5, we didn't have any such problems. It would be good if VMware can offer specific applications for mobiles to enable us to control the management of all servers by mobile. They should also improve the vCenter GUI because it is currently not compatible, and there are a lot of problems. Some of the options do not appear well in the browser. VMware should spend more time resolving the problems in the GUI."
"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."
"From my point of view, my advice is to design the solution properly the first time."
"It would be good if the licensing cost of the solution could be cheaper."
"In the next release, I would like to see programming. I'd like to see a lot more about customization for people who want to customize programming API, SDK."
"I would suggest that the tool reconsider its pricing strategy. The recent price hikes could potentially pose a problem for VMware in the future. The recent price increases, especially since Broadcom acquired them, seem excessive. There are reports of businesses experiencing massive price hikes, sometimes as much as 10-30 times higher. This is causing smaller businesses to consider exiting the space altogether."
