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.

Reliable virtualization has supported smooth DR drills and efficient resource allocation

VMware vSphere has proven to be robust in nature, and the new features are quite acceptable. The new features in NSX network switching make it more useful in the reliability management of data centers. vMotion has helped my organization's business continuity strategies during our planned DR drill activity. The migration of VMs from DC to DR is quite smooth with respect to the network link. I assess the impact of VMware vSphere's High Availability feature on my infrastructure resilience as effective during DR drill activities and firmware upgrades, which we perform every six months. During those times, we rely on maintenance mode of several servers, and HA works properly. I have nothing to complain about. We have utilized VMware vSphere's Distributed Resource Scheduler effectively. Even though we have over-provisioned the vCPUs, it efficiently manages the CPU cores and memory of the servers intelligently, so I am not experiencing any bottleneck in resource utilization. Distributed Resource Scheduler has affected my resource allocation performance positively, providing a 20 percent advantage over my old hardware.

Quotes from Members

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

Pros

"Technical support for RHEV is very fast and good."

"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."

"There aren't any bugs on the solution."

"The most valuable feature of this solution is the support portal."

"It's a scalable solution."

"The solution is easy for us to deal with when comes to application migration and has good compatibility with multiple components."

"The solution is a great all-round product, and the virtualization is especially good."

"The solution is stable, there are no bugs or glitches, it doesn't crash or freeze, and it's reliable with good performance."

More RHEV pros

"In summary, this is a very stable solution and it has been that way for years."

"It is a single pane of glass that lets you access your hosts and VMs, making the solution impactful, as you have one place to go to manage everything from one console."

"Accessibility and the ease of use is unparalleled."

"Stability has always been really well done with VMware."

"You don't need too many people to manage the solution once it's up and running."

"It's running mission-critical and business-critical workloads for our customers, and the experience has been positive."

"Technical support is very good. They are very helpful."

"I recommend this solution to most of my customers because it is very stable, and it has a lot of good features."

More VMware vSphere pros

Cons

"We have found the technical support for this solution to be very slow in responding to our requests for assistance."

"Scalability depends on the applications. Red Hat by itself is not scalable."

"The solution could use network virtualization."

"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."

"Its scalability can be improved. It is not easy to scale, and we hope that Red Hat can provide a more scalable system."

"RHEV is not improving because it has been discontinued. It has been discontinued for years."

"I heard that there are big differences between Red Hat eight and seven, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In term of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment."

"I would love to see better documentation and ease of use."

More RHEV cons

"I would like them to keep the client-based system, even though they are going towards web client."

"OS templates should be readily available, so there is no need to get an OS separately. Only the activation part should be different, which is not presently available due to the need to get the OS from a different location, then create VMs."

"The only problem with it is that it is now in the category of obsolete products. Though it's still very good, its support and updates won't be available."

"In the next release, I would like to see programming. I'd like to see a lot more about customization for people who want to customize programming API, SDK."

"vSphere could perhaps be improved by more integration or better security."

"The biggest thing to improve is to have more self-service in the portals. I would like to receive more help through the web interface."

"VMware is very pricey and really the most useful in very large virtualization environments."

"Not the best choice if you want to start learning virtualization."

More VMware vSphere cons

Pricing and Cost Advice

"I believe we pay on a yearly basis."

"The price of RHEV is high. It is an open-source solution, the price should be less. The price should not be on par with a solution, such as VMware. It's not more or equal to VMware, it's less, but the difference should be more substantial."

"Its price depends on the use cases."

"Price-wise, RHEV is okay, in my opinion."

"We have to pay extra for vulnerability and fault tolerance."

"This product has a variety of licensing options available. However, the level of licensing, and therefore the cost of licensing, is dependent on the number of servers being utilized."

"The solution does not require licencing but a subscription is necessary, which is very affordable."

"This is an open-source solution."

More RHEV pricing and cost advice

"Licensing fees are not paid yearly, or monthly."

"The licensing has become cheaper over time."

"The pricing is a bit complex."

"It is easy to understand the licensing of vSphere. We have standard enterprise licensing."

"I did a comparison between physical server to virtual. There was a point in time where we would size out a virtual server to be a massive size, then we'd buy a physical server of the equivalence. We saved somewhere around 20 percent going virtual, as opposed to the physical equivalent."

"The price could be better. The license is definitely expensive."

"The solution comes with a yearly subscription license."

"Pricing can still be improved for this solution."

Anne Cubarrubia

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.
