This download comes as a pre-configured VHD. This download enables testing of application designs on the Windows Server Platform.
As design gets more closely integrated into the process of building websites and web applications it becomes more critical to have all the necessary software installed on your machine to enable you to preview and review the designs you are working on. Often this is the only way of ensuring your designs will remain intact and look as intended when the finished project goes live on the web.
Working on a web based project today generally involves multiple technologies, databases and web servers, all of which need to be installed on your machine if you want to see exactly how your designs will look out in the real world.
Why waste valuable time installing, configuring, uninstalling and reconfiguring the server environments today’s projects depend on, when a VHD gives you an instant and perfect solution.
A VHD is simply a self contained environment, a virtual machine, with all the software you need already installed, configured and ready for use. Simply run the VHD and you immediately have access to all the software you need to run, build and test your designs in the real live environment and when you’re done, simply close the VHD and the software is gone until you need it again.
Utilizing multiple VHDs preconfigured for different client projects and different configurations gives you maximum flexibility without compromising the stability of your main machine and without repeated and time consuming installs.
