Questions of pricing should really be referred to the vendor (in this case, Amazon) -- Any information we provide may be out of date, or outright wrong... –  voretaq7 Dec 15 '12 at 5:25

Short Answer: Yes - $0.01/GB

As per: http://aws.amazon.com/ec2/

  • No cost between EC2 and OTHER services in the same region (e.g. us-east-1)
  • No cost between EC2 instances in same availability zone (e.g. us-east-1a and us-east-1a) [Using private IP addresses only]
  • $0.01/GB for transfer between instances in different availability zones (in the same region) (e.g. us-east-1a and us-east-1b) - "Regional Data Transfer"
  • Full data rate ("Internet Data Transfer") between services in different regions
