"This product is very user-friendly and easy to use."
"The snapshot feature is very powerful; it protects us from disaster."
"It's a pretty good product in terms of monitoring."
"The installation is easy."
"Technical support is good."
"I like that it is free and runs on Linux/Ubuntu - I wouldn't use any other solution. I am able to perform small developing tests."
"The pause feature is valuable. I can pause, which is something that not all hypervisors allow. The snapshot feature is also valuable."
"It's very simple to use."
"VMware vSphere has very good applications and services."
"The most important feature is the ability to balance the servers with Distributed Resource Scheduler (DRS). It is a very useful feature and should be mandatory for vSphere to have but it is only available in the enterprise edition. It should be available in all versions."
"I have found the solution to be flexible, and the vCenter and vMotion useful."
"The stability of VMware vSphere is very good. It has high resiliency, it is one of the best solutions on the market."
"The most valuable features are the vMotion, the storage vMotion, the DRS, and the high availability function."
"Provides good backup to our servers."
"It is very easy to use and very stable."
"This solution's most valuable feature is its High Availability."
"The memory and hardware usage could be a little bit lighter. Right now, it's quite heavy on the usage. The CPU usage should be lower."
"It has some issues when you have some weird device drivers. For instance, when you have a weird sound driver working on your machine, and the VirtualBox needs to output the sound of the virtual machine into the sound driver of the physical machine, the bare metal, it doesn't work too well. If you tweak lots of drivers and play around with the different kinds of drivers and machines, you will probably break something. I have not played with it too much and maybe it already supports it, but it would probably be good to have the ability to use a container from the virtual machine environment instead of spinning off a complete virtual machine. There are other tools for that. On Linux, you have a DXE, LXC framework, and you have Docker as well. Docker is good because it is multi-platform, and you can run Docker on pretty much anything, even different processors, but it would be good if we had a VirtualBox running on it while spinning off containers instead of full virtual machines. The other thing that will become important, and I'm pretty sure that they are thinking about it as well is that there's this new hardware platform that Apple is releasing, which is an ARM-based new chip. So, VirtualBox will probably have to work on ARM-based CPUs as well."
"When I select the Ubuntu operating system from within the virtual machine, it sometimes hangs."
"Oracle VM VirtualBox is not flexible, It's not like VMware."
"The AI and the UI could be improved. The user interface is a little outdated and the AI is not very attractive."
"There are a few bugs that need to be updated."
"Basically, the GUI and command-line interface need improvement."
"I find the solution to be incredibly unstable, constantly falling over and not working properly."
"The technical support is good. However, it could be more seamless when it comes to chat support and lower response times."
"I would like to see more support regarding containers, and they need more features for them."
"Sometimes it's impossible to prevent problems from happening. With vSphere, you never know where the problem is going to come from, but you will always know that there is a problem. This is the problem."
"The biggest room for improvement would be just simplicity. It is very intuitive, but it needs somebody with a lot of IT background."
"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."
"The biggest problem in this solution is the incompatibility of some of the features with some of the drivers installed on servers. For example, if I want to install vSphere on an HPE server, the driver is really different from a Dell server or a Fujitsu server. I need to download different drivers and install them manually, which can be improved by VMware. They can offer a special image to match different servers. We face different problems when we install vSphere on an ESXi server and have different drivers on the storage. ESXi cannot detect different kinds of storage, and they should improve this. We updated our existing version to vSphere 7 in a private environment, but it seems that this version is not very stable. We are facing issues with restarting the host. In earlier versions, such as vSphere 6 or 6.5, we didn't have any such problems. It would be good if VMware can offer specific applications for mobiles to enable us to control the management of all servers by mobile. They should also improve the vCenter GUI because it is currently not compatible, and there are a lot of problems. Some of the options do not appear well in the browser. VMware should spend more time resolving the problems in the GUI."
"Higher cost than other similar solutions."
"It could be more composable. At present, a fluid pool is not available to us. It would be great to have the flexibility."
