I am building solutions using Azure VDI, but the AADDS component required is too expensive for small teams. For example, I built a VDI for a customer who only employ 4 people. The virtual machine used to deliver the VDI costs just 50 GBP per month (reserved instance), but the AADDS component required for authentication costs 90GBP per month! For small businesses this is not feasible and makes selling VDI solutions very difficult.
