Template:AWS Registration
From GMOD
Amazon Web Services: Registration
Start off at aws.amazon.com
Log in with your regular Amazon account (if you don't have an Amazon account, you'll need to create one)
Theoretically Amazon already knows this stuff, but you have to enter it all again...
You'll need to enter your credit card information to pay for your cloud usage; GMOD has a grant from AWS to allow users a certain amount of compute credit.
Amazon's billing system requires phone verification. Once you have done this, you'll get this confirmation screen:
Credit Where Credit's Due
If you have a voucher for free compute credit, you can apply it at http://aws.amazon.com/awscredits.
