How to Determine Data Transfer Costs from AWS S3 to the Internet by File/Object

Question

Hello,

I'm seeking assistance in analyzing my AWS S3 data transfer costs. Specifically, I would like to understand how to track and identify the costs associated with data transfer from AWS S3 to the internet, broken down by individual files or objects. My goal is to determine which specific files are contributing the most to my data transfer expenses. ( maybe a ranking of objects-data-transfer-cost will be great )

Any guidance, tools, or scripts that you can provide will be greatly appreciated, as I aim to optimize my S3 usage and reduce unnecessary data transfer costs.

Thank you for your assistance.

Answer

S3 Storage Lens would help in identifying what objects are most activre and how much traffic they generate. This isn't always exactly the same as cost but I would think it is pretty good proxy metric.
