, AWS calculator applies the same amount for in-bound and out-bound rates. So if you set the usage of intra-region to 1000 GB you will get:
intra-region data transfer
But's it's probably far from reality. Do we have to split it to 2 sub-usage data for inbound and outbound or just stick to what AWS does for the sake of simplicity?
Intra region: (1000 GB x 0.01 USD per GB outbound) + (1000 GB x 0.01 USD per GB inbound) = 20.00 USD
Monthly data transferred between availability zones in the region. Infracost multiplies this by two to account for AWS charging in-bound and out-bound rates for it.
