The best part is that they support many different versions of windows operating systems like Windows 7/8.1 as well as Linux servers. It's also very simple to use with almost zero maintenance required for us since we are using them only for our application development purposes (no production usage yet). They do offer some free trial time so you can see if this works for you. We're basically developing an application which needs to run within multiple environments such as AWS EC2 instances and local server instances. This helps us test our software locally before deploying to live environment.
