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 initial setup is fairly straightforward and well-documented. The process is very similar to its competitors. The success of your setup depends on how well you plan."
"It is a scalable solution."
"The solution is a great all-round product. The virtualization is especially good."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"This solution is very stable. Much more so than similar products."
"There aren't any bugs on the solution."
"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."
"Stability and speed are the most valuable aspects."
"The tool makes virtualization easy. It was free, and we could profit from its GUI. It helps to manage VMs easily."
"The most valuable features are the resilience of the solution and vMotion."
"The ability to monitor resource utilization."
"The most valuable feature is vSAN, as it reduces the cost of SAN storage and maintenance."
"It's not a particular feature, really, however, I can say that the solution is just easy to maintain, and makes it easy to backup all those VMs. We can easily save our data and we can deploy VM machines very fast and create the delivery of the server in a pretty simple, dynamic way."
"I don't see any challenges in using this product."
"VMware's high availability which supports our SLA, VMware on the fly features like LUN expansion, P2V and API integrations are the most valuable features."
"vSphere brings the features required for an enterprise class system with a lot of supporting components: An intuitive user experience that simplifies and helps operational management."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"There is not any proper documentation on the site to reference."
"The solution should be made more user-friendly."
"A few features of the product do not work as well as those in VMware."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"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."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"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."
"Inability to get to a single hypervisor environment to support a container environment."
"They need to further develop graphics virtualization."
"We've been using vSphere on Windows 7, and it had less fluff associated with ThinApp. Currently, with Windows 10 version that we have, it adds a lot of bulk to ThinApp. We have offices spanning across Canada from the east coast to the west coast. A ThinApp that is roughly around 400 MB in size would take minutes to open up. With Windows 7, the same ThinApp used to be close to 75 to 80 MB in size. So, I'm really not happy with the extra fluff that is bundled in Windows 10. It really messes things up for us at times."
"VMware vSphere is perfect for the on-premise solution, but we are in the cloud era, so I think maybe VMware needs to invest more in the cloud and the microservice chain. It would be better if VMware offered more cloud solutions and continuous applications."
"I would like to see VMware head towards a more GPU friendly environment."
"VMware vSphere could be more secure and well-known to everyone."
"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."
"When it comes to cross-regional (e.g., someone in the US managing the China vSphere implementations), it can be a somewhat slow. I would recommend increasing the speed. While there has already been improvement there, I would like to see more."
