Sharing data between 2 servers in different DC's
I would like to know if it is technically possible to share data between 2 servers, each located in different datacenters.
For excample (for a service), the free server stands in DC A, and for the Pro (paid) service the server is in DC B. When a free user wants to upgrade his account to paid, he basically needs to change server. All his account info needs to be send to the server in DC B. This don't needs to be done in realtime, but can have an interval of 1 hour or something like that.
Would that be possible? Is it just a matter of sending data to a specific IP, where the there located script will do the rest of the work (so it is all a matter of programming), or are there more things to consider?
Thank you very much,
Jacco
