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."
"One of the most valuable features of this solution is the popularity of the OS."
"The solution is a great all-round product. The virtualization is especially good."
"Red Hat is the most stable system."
"RHEV’s cost is much less compared to VMware."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"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."
"I like stability and the organization of the different functions into the I#M feature which is also quite useful, quite stable."
"It's a very useful solution. It's easy to set up, and it's pretty stable."
"Technical support was helpful and knowledgeable."
"It is fairly easy to use and has enhanced security."
"This product is useful for running multiple virtual machines from a single server so that people can utilize the hardware resources in their organization. Its ability for backups is also valuable. In case of a disaster, you can recover the entire server from the images. It is easy to use. In terms of features, whatever they are providing is more than sufficient for us. We are not exploiting this product up to a hundred percent."
"The virtualization is set by itself. vSphere is the best way to have a non-host based fixed solution. We always try to find an agnostic environment where we can restore agnostics or just say, "I need resources, capacity." That's why VMware vSphere in particular, has been the best in the past but now also with the evolution of their product. Nowadays, you don't have to use any STEM infrastructure anymore because the bandwidth and the land speeds are getting steeper."
"VMware vSphere has a lot of features that are valuable, such as multiple clusters, VM mobility, VDI, and virtual desktop."
"There is the simplicity of management, accessibility, and availability."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"The documentation is not as good as it should be."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"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 availability of technical expertise with the solution may be limited in some areas."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"Its performance is an issue in version 6.5, but with the inclusion of HTML files in vSphere version 6.7, the experience is seamless. In version 6.7, VMware has included the HTML file protocol for the web browser or web console, which has changed the console's response and improved the performance. We are using the trial version of vRealize Operations. It would be nice if some of those capabilities could be included in future versions of vSphere, not as a part of vRealize Operations, but in vSphere itself. It can provide some kind of forecast about your resource consumption based on the actual workload and modeling or testing scenarios. It can give you some advice or tips for the future growth of your infrastructure."
"It would be good if the licensing cost of the solution could be cheaper."
"There is still room for improvement with the HTML5 Web Client. They are working on it, as I can see on their blog. However, there is still room for improvement in the newer features that they can push into it."
"They need to stop pushing code out so fast."
"The ability to run ARM based VMs on an x86 platform for testing purposes. With the growing use of SBCs running on ARM architectures for IoT devices, it would be very useful if developers could build and deploy VMs running operating systems like Raspbian used on Raspberry Pi devices on their existing x86 ESXi environments. Even if this is not possible through some form of emulation, the ability to add ARM hypervisors to vSphere environments would be very useful. This will enable more rapid development cycles for customers just getting started with IoT but already existing vSphere users."
"It could be more composable. At present, a fluid pool is not available to us. It would be great to have the flexibility."
"It would be nice if it had auto-scaling, no need to select CPU or select database size. Let it auto-scale, let it use the features that VMware has, instead of having to preselect."
"Without a lot of physical RAM on the hardware, it's not very effective. The stability could be improved in cases like this."
