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.
"This solution is very stable. Much more so than similar products."
"Red Hat is the most stable system."
"Stability and speed are the most valuable aspects."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"The solution has a good licensing module."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"What they provide is way beyond the essential requirements of customers."
"The solution makes migration easy."
"We find the solution simple and efficient to manage."
"I like the capability of vMotion, DRS, high availability, and resource distribution."
"In the past, we struggled with VM encryption. We couldn't encrypt the virtual machines with older versions of vSphere without some kind of third-party tool. Now, with 6.7, it's all in the application itself, in vSphere. We no longer have to procure additional products to meet that requirement. We can just do it on the fly, and pass our audit with no issues."
"One of the most valuable features that vSphere has is its HA and DRS protection, where it can simply make sure that all the machines are always where they need to be and how they need to be taken care of. We have a lot of servers and services for emergency services for police, fire, and the like. We have the ability to use DRS as Anti-Affinity Rules to make sure that those redundant server pairs always stay away from each other. But then, if anything would happen to one of them, we have HA to be able to come up and bring it right up and going again."
"An important vSphere feature from a security perspective is VM encryption. As is the right thing to do in this day and age, security needs to be the number one concern for any IT operator. While there are security solutions which can be delivered at the physical, hardware layer, they don't necessarily address all of the requirements from an encryption perspective. Being able to have VM-centric, VM-level encryption is a great feature of vSphere."
"I like the capability of logging into one system, then being able to shift over to another system within that single pane of glass."
"One of the most valuable features of this solution is the ease of deployment. It's also user-friendly and has been on the market for more than a decade, so it's a leading technology in hypervisor solutions."
"The tool comes with scale-out capabilities. Deploying new infrastructure became much quicker, saving significant time previously spent sourcing hardware for each installation. It also has the ability to downscale on rack spaces, reducing the number of rack units needed to accommodate our servers."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"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."
"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."
"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."
"The availability of technical expertise with the solution may be limited in some areas."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"An improvement could be allowing a "dark mode" for the interface. I think the HTML5 client is a little bit hard to read. It's all white. It's a little bit bright on the eyes. A lot of us IT guys view in the dark."
"The technical support is poor. We are in Australia, but we do not have the same level of support as the US and Europe."
"Pricing is starting to get a little high-end."
"From my point of view, my advice is to design the solution properly the first time."
"The support is good, but it's slow."
"The latest version of the solution has a few bugs."
"The solution is quite expensive."
"The solution could benefit by expanding the CPUs and memory from different physical nodes."
