Question

A company wants to share data that is collected from self-driving cars with the automobile community. The data will be made available from within an Amazon S3 bucket. The company wants to minimize its cost of making this data available to other AWS accounts. What should a solutions architect do to accomplish this goal?

Accepted Answer

**Answer B: Configure the S3 bucket to be a Requester Pays bucket**

Let's break down the requirements:
1. **Share data publicly** with the automobile community (other AWS accounts)
2. **Minimize cost** for the company that owns the data

How Requester Pays satisfies both:
- **Requester Pays** is an S3 bucket configuration that shifts the cost of **data transfer and request charges** from the bucket owner to the requester (the person downloading the data).
- The bucket owner still pays for **storage costs** only.
- When another AWS account requests data from a Requester Pays bucket, they must include `x-amz-request-payer: requester` in their API request header, acknowledging they will pay for the transfer.
- This is the **exact use case** Requester Pays was designed for: sharing large data
