Right now, I would advise it to anybody who has 1,500 or fewer users they wish to provide desktops for. I would advise to go with persistent desktops or use a UEM solution like AppSense or RES Workspace Manager when trying the non-persistent desktops. I would suggest that using an AppVirt product like App-V with Unidesk still makes a lot of sense as you can use Shared Content Store Mode and sequence once for many. AppVirt solutions still have value with isolation. I would suggest looking at Turbo browsers for their redirect feature to an sandboxed browser running legacy IE or a browser with Java or Flash (to eliminate security threats related to these running locally on the system). Also, I would suggest looking at Atlantis for deduplicating those desktops and allow them to perform quicker with less storage required. Unidesk by itself is awesome. It really simplifies things. Throw it together with other products and each compliments the other well. Also, Unidesk makes some of those other products more valuable as you're not completely reliant on them like you would be without Unidesk.
Due to its perpetual licensing model, VMware Fusion is a great option for users whose needs do not change as much over time. It is also great for occasional-use scenarios such as testing and preparing code to run on newer platforms. Fusion is not really recommended for running graphics-intense applications as graphics acceleration in Fusion is fairly limited in both performance and API support. It has, however, come a very long way and offers near-native performance for many tasks.
Disaster recovery options for the Unidesk solution are not easily accessible or require personalized attention from support.
Issues when creating software layers do not always have a obvious fix. Make sure to look for and follow Unidesk's published "recipes."
The software/OS layering introduced by Unidesk is not "sanctioned" behavior by Microsoft, and thus you're at the mercy of Unidesk's ability to keep up with widespread changes to operating systems.
For Apple workstations VMware Fusion is the virtualization software to use. No other application (free or paid) can do what Fusion can. The features and constant updates make Fusion an application that cant be beat.
Sometimes the best surprise is no surprise and Fusion is just that. It's reliable and generally just works as expected every time (the only exception was running a boot camp install directly but that use-case scenario opens a can of worms due to how product activation works) The interface and settings are clean and simple and there is no hide and seek games to play.
I have never contacted VMware, but there is a lot of support online on message boards, forums, StackOverflow, YouTube tutorial videos, and the like. VMware has been around nine years longer than its leading competitor, VirtualBox, although both seem to have a good presence of online user communities who can help solve issues that come up.
AppVolumes seems to be a lot less mature as a product. It does have some benefits over Unidesk e.g. the fact it doesn't include the OS Layer (image management) side means I can just use it for the app layering piece if I like. I can also deploy my application layers to physical desktops BUT I have had less success compatibility wise with my applications as AppVolumes 'AppStacks'. I believe Unidesk has a better handle on the do's and don'ts, or at least may be a little more honest about them. I also don't enjoy the Console with AppVolumes and while I can use it without the image management or tied into the stack the way Unidesk is...you also lose that image management and need to couple it with another product in some scenarios. FlexApp to me is stronger than AppVolumes. FlexApp is coupled with a profile management solution called ProfileUnity which makes it a more attractive alternative (at least at the time of me posting this). However, I prefer other UEM products at this moment in time. I also value the image management and ease of a single console for all of Virt Desktop management that Unidesk provides.
I've heard of other/competitive software but frankly once I tried VMware, I never looked back. There is absolutely nothing that I need that this product does not deliver. It's fast, effective and seems to be extremely durable and reliable. My only concern (and minor) might have to do with memory resources, but frankly it has not been an issue yet.
Storage density with Unidesk (via the use of OS/application layering) is 60-70% improved over standard persistent one-to-one virtual desktops.
Unidesk virtual machines can be deployed in under 10 minutes by a lower tier of technician without the need to "touch" the vCenter hypervisor.
Reliable performance across Unidesk virtual workstations. Added desktops/layers does not adversely effect performance nearly as bad as older persistent desktops.
Users using a VM often don't need something as "fancy" as VMware Fusion, and instead can use a free option like Virtual Box, so we waste money on using an extra amount of VMware Fusion licenses.
Developers using and IT admins using VMware Fusion for testing saves us time and money. Simply, we know mistakes would take time and money to fix, but VMware is powerful, allows for proper and fast testing.
