Mike Neuliep

Linux Systems Engineer at a tech services company with 10,001+ employees

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.

GourabDas

Senior Manager at a financial services firm with 1,001-5,000 employees

Virtualization has transformed our data center and delivers consistent uptime with seamless maintenance

The most valuable feature VMware ESXi offers me is the user interface and the ease of handling operations without downtime, which is the biggest advantage, particularly with capabilities for live patching, and VCF 9 in patching areas; the bundled licensing provided simplifies management as I can utilize resources based on my needs without worrying too much about individual licenses. The zero-downtime patching is the feature that makes the biggest difference in my day-to-day operations, as well as managing hosts with an n+1 configuration, using a buffer host to streamline maintenance within a cluster of hosts. The vMotion feature is another important aspect, as we opt for auto vMotion to optimize resources within the cluster, enabling the underlying VMs to be moved seamlessly from one host to another based on utilization without impacting applications. VMware ESXi has positively impacted our organization significantly in terms of operations and cost optimization, as we optimized our environment under a per-core license agreement, achieving around 30 to 40% cost-effectiveness and maintaining almost 99.99% uptime across our environment, where VMware ESXi is run on about 85% of our setup. Improvements in operations were made possible through visibility provided by VMware ESXi into hardware enhancements, such as virtual storage platforms with vSAN, which we incorporated into our environment supported by VMware ESXi 9 to enable effective live patching without impacting operations, and we regularly utilize RV tool reports to track actual utilization and optimize resources, reducing our footprint from 100 VMs on 100 hosts to 47 hosts, yielding substantial financial benefits thanks to the support from our VMware ESXi TAM.

Quotes from Members

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

Pros

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

"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."

"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."

"It's a very good platform to build your virtual machines on and highly integrated with Red Hat itself and its satellites."

"When any organization needs end-to-end infrastructure deployment, configuration management, and automation, then RHEV is the best fit."

"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."

"Red Hat Enterprise Virtualization Hypervisor has robust virtualization management features with proven enterprise security and performance."

"The support for this solution is very good."

More RHEV pros

"I rate the stability of the solution as either nine or ten out of ten."

"All the features of VMware ESXi are very beneficial, particularly for virtualizing our infrastructure."

"The ease of use would be the first feature I like, then reliability."

"For enterprises seeking scalable and robust solutions, VMware ESXi is highly recommended."

"VMware ESXi provides high availability and a good web interface."

"Using VMware ESXi for server management significantly simplifies the process. Traditionally, procuring physical servers was necessary, but now, we can create virtual machines on VMware ESXi based on our requirements. As long as resources are available, we can create as many virtual machines as needed."

"VMware ESXi is a very stable infrastructure since I have been using it, and it is very reliable."

"VMware ESXi has positively impacted our organization significantly in terms of operations and cost optimization, as we optimized our environment under a per-core license agreement, achieving around 30 to 40% cost-effectiveness and maintaining almost 99.99% uptime across our environment, where VMware ESXi is run on about 85% of our setup."

More VMware ESXi pros

Cons

"A few features of the product do not work as well as those in VMware."

"The documentation is not as good as it should be. There is a need for making it descriptive and in sequence."

"I have found that the stability is related to the upgrade cycle. I find the cycle a little bit annoying; if the system is constantly upgrading then it is very painful in terms of the operation."

"The GUI interface needs improvement. Not 90%, but 50% or 60% of the work is done from the command line and so on, so the GUI needs work because people are looking for an easier way to manage the environment."

"While everything needs improvement in some way, I have no specifics."

"The Administration of the Oracle database and the SAP ERP needs improvement."

"The solution has a very small lifecycle."

"I found it a bit more difficult to manage than version seven, which was much easier."

More RHEV cons

"The price point could be improved."

"VMware is very costly."

"We often face issues with ESXi that require us to change resources by shutting down the VMs."

"The licensing model currently presents challenges. It's not cost-effective for small users and creates a gap for alternatives, while favoring larger clients."

"It would be really helpful if there were options to do things in one or two clicks rather than doing everything through more manual interaction."

"The cost of VMware ESXi is very high, especially after the acquisition by Broadcom, which led to price increases. Improving the cost structure would be beneficial."

"There have been issues with the tool's technical support and pricing of licenses, making them areas where improvements are required."

"The license model has recently changed, which is a bit worrying for customers."

More VMware ESXi cons

Pricing and Cost Advice

"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."

"We buy a license for commercial use, and we also use the free editions."

"This is an open-source solution."

"RHEV offers pricing based on a per-physical-machine licensing model."

"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."

"I believe we pay on a yearly basis."

"I would say the price is acceptable."

"We are using the free version of Red Hat."

More RHEV pricing and cost advice

"The tool has become expensive."

"The pricing is expensive, with the cost for customers ranging from $10,000 to $20,000 yearly."

"Broadcom recently purchased VMware, and the pricing scheme has changed. If I need any more features in the tool, I can actually purchase them."

"VMware ESXi is a costly solution in Africa and other developing countries."

"The solution is expensive."

"I rate the product price as one on a scale of one to ten, where one is high price and ten is low price."

"The solution is priced on the higher side."

"The product pricing was reasonable before, but recent changes, including bundling, have complicated the cost structure."
