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 this solution is the support portal."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"There aren't any bugs on the solution."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"This solution is very stable. Much more so than similar products."
"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 overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"The most valuable feature of the solution is its performance."
"We can slide in new resources without any impact. We can do maintenance on our clusters without any impact to applications, and we have the flexibility of migrating those workloads to other data centers, when required, in the case of data center downtime."
"vRealize Operations Manager is the most valuable feature, but it is not embedded in vSphere; it is a part of vSphere. It is used for forecasting and checking the consumption of CPU, memory, and other resources. It has the capability to do the forecast based on the history and give advice on consumption. VMware vSphere is easy to use and easy to implement. Its learning curve is not sharp. Any engineer with little or medium knowledge of hypervisors and virtualizations can implement vSphere with a few clicks."
"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."
"Some of the most valuable features are: the ability to Snapshot so that when we do updates we have a layer of protection for simplified rollback; the replication that we can leverage for data center failures and data center downtime; the ease of migrating workloads from physical device to physical device for maintenance that we have to do on physical servers."
"The initial setup is very easy and takes half an hour to complete."
"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."
"The most valuable features are the seamless HA with vMotion and being able to run vCenters in HA mode."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"The documentation is not as good as it should be."
"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."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"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 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."
"While everything needs improvement in some way, I have no specifics."
"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."
"These days we have an environment where we are often using clouds as well. A solution that would be a little more cloud-aware would be really helpful. I know there is a product from VMware that is more specifically for the cloud, but it would be nice if VMware Cloud Manager would be cloud-aware. It would simplify certain processes."
"There are some challenges around ESXi hosts — converting them into VMs."
"I would like to see VDP and other features included to back up the VMs in a native manner."
"I would like to see DRS for the GPU machines."
"As we continue to push mission-critical workloads into vSphere, and those workloads are not readily protected at the application layer for availability, continuing to increase the size limitations on FT-protected VMs would be a great advance."
"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."
"It could use a smaller learning curve."
"It could improve the hyper-conversions."
