Amazon S3 (Simple Storage Service) lifecycle management is a set of rules that automatically manage the lifecycle of objects in an S3 bucket.
These rules can move objects to different storage classes or delete them after a specified time.
Benefits :
Cost optimization : Automatically move less frequently accessed data to lower-cost storage classes
Performance optimization : Move objects to the most appropriate storage class as their access patterns change
Data durability : Automatically move objects to the most appropriate storage class as their access patterns change
Compliance requirements :
Simplify compliance requirements
How it works :
* Transition actions: Move objects between storage classes at pre-defined intervals
* Expiration actions: Delete objects after a specified retention period
* Object tags: Specify which objects are eligible for a lifecycle action by using object tags
Examples :
* Move objects from the default S3 standard tier to Standard-IA (Infrequent Access) 30 days after they were created
* Move objects older than 30 days to a cheaper storage class like Glacier
* Permanently delete objects that are no longer needed after a specific timeframe
