Recently I build a XenApp environment on Azure for demo purposes. I used –> this <– website helping me calculating the costs.
This website (running on Azure :-)) makes it easy to calculate the costs of your XenApp/XenDesktop environment on Azure.
You can provide the locations, working Hours, Workloads and number of users (and their profiles). It automatically loads the costs of Azure (so no outdated data!) for Comput, Storage and Network.
