I haven't used it as much over WAN connections but I am familiar with Teradici's efficiency over slow links. In our LAN, environment, the best feature is central management and small footprint. These primarily go into lab, testing and kiosk areas due to minimal hardware outlay and easier to lock down.
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.
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.
I made an 8 because it's good in almost every aspect. As I said if you are on macos and you need both windows and linux I think is the best options out there. Otherwise if you need only windows there is a competitor that could be better for performance and integration.
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.
VMware Blast! is now VMware's standard for VDI. It has some features that make it better in a VMware environment. Existing PCoIP systems we have are Teradici-based so I am glad that standard is still available. When it comes to hardware, Teradici is still the most available so we continue to choose them.
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.
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.
