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 most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"It is a scalable solution."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The solution makes migration easy."
"This solution is very stable. Much more so than similar products."
"Red Hat is the most stable system."
"The solution has a good licensing module."
"One of the most valuable features of this solution is the popularity of the OS."
"The built-in encryption of vSphere really helps us to secure our customers, especially customers in the medical field who need to be HIPAA compliant. Being able to encrypt the VM itself helps out a ton."
"I think that the solution is perfect. It's the best on the market."
"The solution has many valuable features. Virtualization is flexible and it has simple clustering. However, the most important feature is the ability to move between VMs. The vMotion features are very good."
"In terms of overall features, vSphere's stability stands out on top. Not only is it highly stable, but we're also able to have a quick backup server on standby."
"Technical support is helpful and always available."
"The most valuable feature is vSAN, as it reduces the cost of SAN storage and maintenance."
"The scalability has been good."
"The most valuable features are that it's stable, easy to use, and it's flexible."
"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."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"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 Administration of the Oracle database and the SAP ERP needs improvement."
"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."
"A few features of the product do not work as well as those in VMware."
"The solution should be made more user-friendly."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"VMware vSphere could be improved with cheaper costs."
"Although vSphere is a nearly perfect product, it does need a little improvement. Datacenter and Cluster structure should be mixed so that the management of clusters would be easier."
"Not having to buy something from a third-party to scan the actual hardware components, like the hard drives and the port containers and fan speeds; not having to bolt something on and go through another vendor, would be helpful."
"VMware has amped up how frequently they release new versions and that adds instability to a stable environment."
"Its price should be better. Their support should also be more customer-friendly, and they should train people like us so that we know more about the latest technologies and features. If there is some program and drive from their side to teach us, it is definitely going to help us. Pricing and support are the most important features for mid-level companies. We are not implementing this solution for big tech companies."
"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."
"The licensing costs are expensive and most of the important features require a license."
"The price could be better."
