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 solution is stable."
"One of the most valuable features of this solution is the popularity of the OS."
"What they provide is way beyond the essential requirements of customers."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"There aren't any bugs on the solution."
"It is very stable."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"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 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."
"An easy way of providing near-zero downtime services, the operation of the instances between clustered services, and providing the projected SLA for our customers."
"Having a virtualized infrastructure and being able to bring up Windows, Linux, and VMware within a virtualized environment brings more technology into the classroom. Without it, we couldn't do what we do."
"The solution has high availability."
"The ability of a running VM to be quickly relocated to another hypervisor or launched at another site via replicated storage greatly reduces downtime."
"I use the ESXi a lot for my users to create their own templates and control their own VMs without my interaction."
"VMware vSphere helps us in not wasting resources like we did when we were using physical servers. It changed our whole environment."
"We are able to patch our hosts during production hours with the ability to keep services running."
"There is not any proper documentation on the site to reference."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"In comparison to VMware, this solution isn't as stable. We're testing it right now, and we're not trusting the stability of the product."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"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."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"Pricing is starting to get a little high-end."
"It is expensive. They can improve the licensing cost for Cloud Director. They can also improve the integration with other applications and the metering feature, which is currently not flexible."
"The only concern that I have with VMware is the support. It is very limited and can be better."
"The documentation could be improved. It does not help me to show the client the value of going with VMware vSphere rather than an open source or cheaper solution."
"I can't speak to any missing features. It has everything I need."
"I would like to see DRS for the GPU machines."
"The hardware cost is high."
"The only way for it to be a complete product is if you integrate all the functionalities. Then you don't need any backup solution anymore and you can do it by yourself. Integration needs improvement. They should improve a lot of the functionality because normally it's half of a product. You're only protecting yourself against technical failures but not against any cyber threats or any other stuff."
