In Amazon S3, Requester Pays is a bucket-level setting that shifts the responsibility for data transfer costs from the bucket owner to the requester (the entity accessing the data).
Here's a breakdown :Traditional Model :Bucket owner pays for all costs associated with the bucket, including data storage and transfer.
Requester Pays Model :
* Bucket owner: Still pays for data storage.
* Requester: Pays for the cost of data transfer when accessing objects from the bucket.
Key Points :
* Cost Allocation: Requester Pays allows bucket owners to share data without incurring data transfer costs.
* Data Sharing: It's ideal for scenarios where data is shared with external parties or other AWS accounts.
* Control: Bucket owners retain control over who can access their data and incur costs.
* Billing: Requesters are billed for data transfer based on their AWS account.
Example :Imagine a research institution storing large datasets in an S3 bucket. They can enable Requester Pays to allow other researchers or institutions to access the data without the research institution incurring data transfer costs.
In essence, Requester Pays provides a flexible cost model for data sharing in Amazon S3, enabling collaboration while optimizing cost allocation.
