I am trying to share my data with ESRI via its community sharing program. I want to able to simply create my own Server and share it that way (through a URL possibly). Is this possible? if so how?
Take a look here for starters: Community Maps : click on the Q/A link
eventually, you'll go here:

You can indeed provide a server/rest end for them to extract your data.
