We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
"Our production servers are running in Linux, and this solution supports that environment well."
"Scaling the solution is easy. You just have to add more hardware."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"The KVM service is well managed with a central policy interface."
"If you prefer command-line, there are all kinds of command-line options."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"The GUI interface makes the management of KVM easier than ever before."
"This solution is open source and easy to configure."
"The most valuable feature is vSAN, as it reduces the cost of SAN storage and maintenance."
"Production people can quickly reboot the server with ESXi Quick Boot."
"The free ESXi hypervisor was a great way to get started, as it allowed us to introduce virtual machines so that users could start to experience the advantages."
"It has allowed us to be more resilient to infrastructure and hardware failure, reduced hardware costs, and decreased recovery time from failures."
"The vMotion in particular I think is the most valuable because this feature provides migrations of virtual machines in case you want to run do maintenance."
"The most valuable feature is the VDP Backup solution."
"The ability of a running VM to be quickly relocated to another hypervisor or launched at another site via replicated storage greatly reduces downtime."
"Its DR facility is good. Within a moment, data can be retrieve from another physical location over the Internet. The speed to recover data is good."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The solution should be more user friendly. We are struggling with the command lines."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines."
"Its resource usage can be improved."
"Business continuity features need to be added."
"There are some issues with the graphics and some software that is very complex."
"Reporting on vCenter needs to be improved."
"I would like more Amazon stuff inside of VMware."
"It would be great if the free version included a management tool that was a scaled-down vCenter Manager."
"Reducing the cost of vSphere would be an improvement."
"I would like to see VMware vSphere provide a centralized patch service on the VMware level, regardless of your operating systems."
"I would like to see better fault and performance reporting in the GUI."
"The ability to run ARM based VMs on an x86 platform for testing purposes. With the growing use of SBCs running on ARM architectures for IoT devices, it would be very useful if developers could build and deploy VMs running operating systems like Raspbian used on Raspberry Pi devices on their existing x86 ESXi environments. Even if this is not possible through some form of emulation, the ability to add ARM hypervisors to vSphere environments would be very useful. This will enable more rapid development cycles for customers just getting started with IoT but already existing vSphere users."
"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."
"This solution is an open-source, free platform with paid support."
"It is free for everyone."
"The price is fair compared to others. But in our local market, it's a problem to get budget approval from management. That's why they are trying to get those products so we can give them the price benefit. But if you consider the international market or other products, it's sometimes better than their price."
"The price is high, but you get back a lot."
"Our ROI is good."
"There is an average performance boost, especially if you use VM encryption inside the VMware with another product, like McAfee. You will see great improvement in these cases."
"The license of VMware is a one-time payment and you can continue to enroll in support for troubleshooting and also administer the licenses."
"Do not buy based on price alone. Many of my customers chose the lowest cost option only to discover that the additional funds needed to access even a few more features would have been money well spent. Likewise, if you are going to spend more money on additional features, then have a plan to actually deploy and integrate those features into your infrastructure. Many customers never take full advantage of the many features that they are paying for and that can be avoided by being proactive in developing your overall vision for the infrastructure."
"You will find the cost is reasonably cheaper."
"It is expensive in terms of cost, licensing, and professional services."
"VMware is costly versus other competitors but is still one of the market leaders and expanding now with partners like AWS."
