Mike Neuliep - PeerSpot reviewer

Has supported virtualization projects in side jobs but has required workarounds due to lack of maintenance
In my opinion, the best features of RHEV are that it is a real hypervisor and it is free, so it performs better than VMware. I have used the live migration feature in the past with RHEV. There is a free clone of it that is based on the open source. Live migration is a nifty feature if your app is not highly available and you need to do maintenance on a machine. You can migrate the VM off of it, do your maintenance, and move it back when you are done. RHEV has a high availability architecture with a built-in monitoring feature where you could see machines other than the one you are operating on. I tend to implement high availability not so much in RHEV, but by using standard application high availability strategies. Red Hat has another product specifically for high availability.

Has improved infrastructure monitoring and resource management but requires better support and cost efficiency
The high availability feature's resilience is not bad, but it could be better. For example, whenever you lose any hardware, you will have interruptions on the services, and it reboots again on the other hardware host which is available at the crash time. That's good, but we would prefer to have zero downtime instead of the rebooting on the other server. We would prefer to have a zero downtime always-on configuration. VMware vSphere has a built-in feature called Fault Tolerance, but it's very limited for very limited VMs or very limited core count or CPU count, so it's not so useful for all the environment because of the limitations. The Fault Tolerance (FT) feature is very limited to very little core counts or very little VM counts, so you can't run the Fault Tolerance for all the servers or all the VMs, and that's very bad. If VMware vSphere could have any kind of built-in patch management environment with a repository, offline repository option, with test, non-production, and production environment separated, this would be perfect. Management of patch management with operating systems and including third-party applications which are running on the servers would enhance the VMware vSphere environment. VMware vSphere is very expensive. The worst aspect of VMware vSphere is the price. I can't tell you the exact cost at this time because the other team members in my teams are working on it, but I remember that the prices are very high. VMware vSphere is easy to scale, but it could be better, similar to a Kubernetes environment. It should have an automatic scale-out feature when the load gets high; if it gets some scale out automatically, it would be better than this, similar to Kubernetes or OpenShift.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"In my opinion, the best features of RHEV are that it is a real hypervisor and it is free, so it performs better than VMware."
"It is very stable."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"When you purchase RHEV, you are essentially buying a subscription license. This license can be integrated with various client types, including these integrations with the subscription."
"It is a scalable solution."
"RHEV’s cost is much less compared to VMware."
"In my opinion, the best features of RHEV are that it is a real hypervisor and it is free, so it performs better than VMware."
"It is a stable solution...It is a scalable solution."
"Server Virtualization is the most important feature because that helps me to utilize 100% capacity of my physical server or box. Its redundancy, uptime, or high-availability is also valuable. Storage-sharing is also valuable. In vSAN, I can utilize the maximum storage. In the physical boxes, if you don't require storage, it lies idle, but with VMware or any kind of virtualization, you can utilize the full storage."
"The most valuable features are stability and support."
"Scalability is the big advantage of it. The product itself allows us to scale on the fly as we need it, and plan for the future."
"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."
"This product is useful for running multiple virtual machines from a single server so that people can utilize the hardware resources in their organization. Its ability for backups is also valuable. In case of a disaster, you can recover the entire server from the images. It is easy to use. In terms of features, whatever they are providing is more than sufficient for us. We are not exploiting this product up to a hundred percent."
"The most valuable features are the virtualization and the performance on the virtualization platform."
"The stability of VMware vSphere is very good. It has high resiliency, it is one of the best solutions on the market."
"Technical support is very good. They are very helpful."
 

Cons

"We should improve how we manage storage domains and make more comprehensive control available through the command line."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"My teammates and I often complain that VMware is well-documented and has a large community since it is the de facto standard. I would love to see better documentation and ease of use."
"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."
"It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period."
"RHEV is not improving because it has been discontinued. It has been discontinued for years."
"RHEV is not improving because it has been discontinued. It has been discontinued for years."
"A few features of the product do not work as well as those in VMware."
"Both the price and the licensing fee are expensive, especially for our clients with a smaller workload."
"The biggest room for improvement would be just simplicity. It is very intuitive, but it needs somebody with a lot of IT background."
"As we introduce the DevOps culture, we need to make sure that the principles and tools used to support this approach can be easily integrated and interoperated with the vSphere environment with no (or less) redundancy in tools and functionality."
"The cost can be better."
"I would like to see VDP and other features included to back up the VMs in a native manner."
"The solution could be cheaper and less expensive."
"We want to see improvement from VMware with security. We want minimal downtime. We want automation. We want to deploy more efficiently."
"An improvement could be in terms of keeping up with the upgrades. The upgrades could be set in an automated way so that the newer features don't require you to manually update, or you get an option to update automatically. This would be a useful enhancement."
 

Pricing and Cost Advice

"It's a budget product as far as I'm concerned. It's way cheaper than any of its competitors. The only thing cheaper than Red Hat is that the people who take the Red Hat code clone it and then self-support it."
"I believe we pay on a yearly basis."
"Its price depends on the use cases."
"We have to pay extra for vulnerability and fault tolerance."
"I would say the price is acceptable."
"We are using the free version of Red Hat."
"RHEV offers pricing based on a per-physical-machine licensing model."
"We buy a license for commercial use, and we also use the free editions."
"My advice when it comes to pricing is that pricing is a bummer, especially when it comes to SnS coverage."
"Once you pay for the standard license, that's it unless you want another feature to be activated. That's a different thing."
"I'm satisfied with the VMware vSphere price. They have a bundle that is priced well. However, any advantage feature is very costly."
"The price could be lower."
"The pricing is more expensive than Microsoft."
"The license of VMware is a one-time payment and you can continue to enroll in support for troubleshooting and also administer the licenses."
"There is an annual cost for the use of this solution. The price is a little high in developing countries. If they were able to reduce the price they would receive more customers now and even more in the future."
"We pay for the license of VMware vSphere yearly."

Here is a comparison of the two hypervisors, RHEV (Red Hat Enterprise Virtualization) and VMware vSphere: RHEV Pros: Open source Highly scalable Cost-effective Cons: Not as mature as VMware vSphere Not as widely supported as VMware vSphere VMware vSphere Pros: Mature and widely supported Wide range of features Easy to use and manage Cons: Not open source Can be expensive Some prefer RHEV because it is open-source and cost-effective. However, VMware vSphere may be the better option if you need a hypervisor with a wide range of features and support. As to which solution consumes fewer resources, RHEV is a lighter-weight hypervisor than VMware vSphere, so it consumes fewer resources. However, you must remember that each hypervisor's resource consumption depends on the configuration and workload.

Why KVM??? Help please!
We use VMware and KVM. We find that KVM is a lot simpler to use and it provides the virtualization we need for Linux and Windows. For us, VMware does not offer any advantage. Moreover, KVM is free.
Proxmox vs ESXi/vSphere: What is your experience?
For me the biggest impact is the cost of licensing in the case of VMware despite its overall intuitiveness and ease of handling and management. However, KVM-based Open Source solutions are becoming...
