I was thinking how to try new release of AX 2012 when the test environment (virtual machine) provided by Microsoft is quite demanding and I have no server with required configuration.
I found this article about how to set up AX 2012 R3 demo on Azure. Hope it will help.

Note: You will need acces to Dynamics Lifecycle Services (https://lcs.dynamics.com/) and some Azure subscription.
