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 price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"One of the most valuable features of this solution is the popularity of the OS."
"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 most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"The most valuable feature of this solution is the support portal."
"The solution has a good licensing module."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The UI is very intuitive, you don't have to spend hours before you figure it out. All in all, compared to other environments, like Hyper-V, we find vSphere a lot more user-friendly and intuitive to use."
"The speed of the solution is excellent."
"VMware vSphere helps us in not wasting resources like we did when we were using physical servers. It changed our whole environment."
"It is fairly easy to use and has enhanced security."
"Scalability is the big advantage of it. The product itself allows us to scale on the fly as we need it, and plan for the future."
"The ability to monitor resource utilization."
"It provides a new environment in an expedient manner."
"It's a very useful solution. It's easy to set up, and it's pretty stable."
"The solution could use network virtualization."
"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."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"Specifically, enhancements in managing virtual machine migrations, cloning, and the creation of different VMs could further optimize its functionality."
"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."
"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."
"They can lower the price of its license."
"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."
"A fully **automatic** and lightweight Virtual Center. Another time this has a huge improvement in last releases. However, a more automatic and simple deployment is required."
"The technical support is poor. We are in Australia, but we do not have the same level of support as the US and Europe."
"The improvement is more from a licensing perspective rather than from a feature functionality perspective. There could be more flexibility and fewer model options to make it easier to sell. Today, there are so many different options available, and sometimes, it is not really clear which one is the right version or the right model to propose."
"VMware vSphere could be more secure and well-known to everyone."
"We need to improve availability and disaster recovery in VMware vSphere."
"As far as the web client goes, one of the frustrating things is that it's dependent on different browsers. One day it may work with only a given browser or there may be issues with Flash. So I look forward to being able to use the HTML 5 client."
