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.
"It is a scalable solution."
"The solution has a good licensing module."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"What they provide is way beyond the essential requirements of customers."
"The solution makes migration easy."
"There aren't any bugs on the solution."
"The solution is stable."
"It's extremely simple. Installing the ESXi is a piece of cake and then putting servers on there is really simple and having HA and building a cluster for our VM servers. It's very easy."
"VMware vSphere is the best private-cloud solution."
"The fact that we have the ability to easily scale out, and the ability to do maintenance on the underlying hardware without impacting our business applications, are important aspects."
"VMware vSphere is easy to scale. We haven't had any problems scaling what we're scaling now."
"It is easy to maintain our data machines and take snapshots with the solution."
"The features in VMware vSphere data recovery are excellent. Sometimes I've deleted an entire server before and was able to recover the deleted VM. I just used some command line tools and I was able to restore the deleted VM."
"Performance; We have seen a performance boost because we have been able to more dynamically allocate either memory or processors."
"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."
"There is not any proper documentation on the site to reference."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"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 solution has a very small lifecycle."
"While everything needs improvement in some way, I have no specifics."
"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."
"The documentation is not as good as it should be."
"They have multiple components required for the setup. It would be better to integrate it into one solution, especially for small business companies."
"I would like to see better fault and performance reporting in the GUI."
"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."
"I would like to see the UI incorporating all of the functionality that the thick client had."
"If they improve on the knowledge base and documentation, it would be extremely helpful."
"Higher cost than other similar solutions."
"The solution is stable. It has some small bugs which are not influencing the main functions but every software has some bugs."
"There are occasionally bugs or errors."
