I have an application that is a good fit for a Windows cloud server and have directed several clients to Amazon AWS here and in Europe. However I have no idea how to compare the costs of AWS compared to renting space on another service or taking an in-house approach with a VPN for external access. Does anyone have any server-only AWS numbers to share for a small business context (3-4 users, with moderate application use)? The only numbers I've seen are quotes from local companies offering cloud servers, and they seem exorbitant as a monthly expense. Thanks for any input.
