AWS S3 pricing for data in out

Question

I am storing objects in S3 standard storage each object could be of 100MB in size so monthly it could go upto 1TB. I will be using a single region to store these objects in S3. I want to create an app to store and fetch this objects using post/get apis then show them in my app. My question is around data transfer in/out pricing, in my case above will I be billed for data transfer in/out?

Answer 1

All traffic from mobile phones to S3 or EC2 is free and all traffic to mobile phones from S3/CloudFront is billed according to a selected region. Take a look at https://aws.amazon.com/s3/pricing/. Keep in mind that incoming traffic (to S3) is free only if you're NOT using S3 Transfer Acceleration. You can also check the S3 calculator to have a better idea regarding the same.  https://calculator.s3.amazonaws.com/index.html
