Explanation

AWS pricing for data transfers follows these principles:

• Inbound data transfer from the internet: FREE - AWS does not charge for data transferred into AWS services from the internet
• Outbound data transfer to the internet: CHARGED - Data transferred out to the internet is subject to tiered pricing
• Data transfer between AWS Regions: CHARGED - Cross-region data transfer incurs costs on both sides
• Data transfer between Availability Zones: CHARGED - Inter-AZ data transfer is charged per GB in both directions

For the 2 TB data transfer scenario:

• If the company is receiving 2 TB of data from the internet into AWS, there would be no cost
• Any other direction (outbound, cross-region, or cross-AZ) would result in charges

This AWS pricing model encourages customers to bring their data into AWS while charging for data egress, which aligns with AWS's business strategy of keeping data within their ecosystem.
