I've used a dedicated server for many years, but I thought I'd try the AWS cloud as an alternative. I've set up the instance, ported my AVLA license, and now I find half of my users are not able to connect. Cloud 17 ONLY connects to 17 clients!!! Why was this not in MUCH BIGGER LETTERS!!! I very wrongly assumed the compatibility of Cloud was the same as Server 17, which is 15, 16 and 17. Cloud isn't even n-1. This out Microsofts Microsoft!
I'm sure there's very good reason, and don't bother with the "should have done your research" nonsense. I just think this extremely poor, and has left me and Filemaker looking very stupid right now.
