I have a client who is switching everything (or as much as they can) to the cloud.

Currently they host their own website, MS Exchange server, etc... They wish to do away with the server, which in my view is a silly idea, although someone here may have alternative thoughts on this.

On the current server I have their main office software (written with DataFlex 19.1 with DataFlex Reports 7) and as they have people out in the field they also have a DataFlex Webapp on the same server.

Long story short, how much of this can be placed in the cloud?
