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 has a good licensing module."
"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."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"It is very stable."
"The solution makes migration easy."
"Red Hat is the most stable system."
"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."
"The solution is a great all-round product. The virtualization is especially good."
"We saved a lot of time and hardware with this solution. It also prevents fewer incidents."
"I don't see any challenges in using this product."
"The tool provides 99.99% uptime."
"The most valuable feature would be the slight changes they've made to VMFork instant cloning, in which they have abstracted out the parent-child relationship in cloning, in which certain features, like HA and DRS, are now usable on that parent virtual machine. That is wildly amazing and something that wasn't available until 6.7."
"The solution saves cost."
"VMware vSphere is a stable platform. We never had any issues with VMware vSphere. Once you deploy it with a stable version of the server or the hardware, there's no issue at all."
"The solution's flexibility allows us to implement it widely."
"The most valuable features are the resilience of the solution and vMotion."
"There is not any proper documentation on the site to reference."
"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."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"The availability of technical expertise with the solution may be limited in some areas."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"The UI should be more interactive with additional features."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"In the next release, I would love to have Java as a service, platform as a service, and container as a service."
"The solution could be more stable."
"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."
"I met with the lead solutions architect for vSphere, and one of the things that I really kind of sat him down on was, "What's the deal between these Custom Attributes and these Tags? What are you trying to do with that?" He said, "So here's the deal. I know that they're halfway done and we have a vision of where they're all going, but we'll get it there." That that would be a great ability, to keep all that metadata about your virtual machines inside the solution and staying with the machines."
"The solution should be more secure."
"The web user interface can be a bit clunky from time to time, so there may be some room for improvement in that regard."
"I'm using vSphere at a high level. Sometimes, I find it challenging to integrate different networks, but I think it's just my lack of knowledge."
"VMware vSphere does not permit hard partitioning."
