Consider this scenario Two EC2 Instances in two DIFFERENT accounts in us-east-1 communicate over the Public IP (The two accounts are not linked and there is no VPC-peering or anything)
EC2 A -----[us-east-1 over public IP]-----> EC2 B
It is very clear for me that the EC2 A will pay for Data Transfer OUT
BUT
1) How much is EC2 A charged for Data Transfer OUT ?
- (a) $0.090/GB - Data Transfer OUT From Amazon EC2 To Internet
- (b) $0.010/GB - Data Transfer OUT From Amazon EC2 To Amazon EC2 in the same AWS Region Using a public or Elastic IPv4 address
2) How much is EC2 B charged for Data Transfer IN ?
- (a) $0,000/GB - Data Transfer IN To Amazon EC2 From Internet
- (b) $0,010/GB - Data Transfer IN To Amazon EC2 From Amazon EC2 in the same AWS Region Using a public or Elastic IPv4 address
I already contacted the support and got different answers, so I'm confused and hope that someone from AWS or community could solve this confusion.
