Lifecycle of S3
In the previous post, I discussed the S3 storage classes. Objects can be transitioned between these storage classes depending on how critical the needs are.
For infrequently accessed objects, they can be moved to STANDARD_IA, and for archive objects that are not needed in real-time, GLACIER OR DEEP_ARCHIVE.
Transitioning of objects can be automated using a lifecycle configuration
S3 Lifecycle Rules
Transition actions: It defines when objects are transitioned to another storage class.
- Move to Glacier for archiving after 3 months
Expiration actions: Configure objects to expire (delete) after some time
- Log files can be set to delete after a 90 days
- Can be used to delete old versions of files (if versioning is enabled)
- Can be used to delete incomplete multi-part uploads
Note: The value of days transitioning to intelligent_tiering must be at least 30 more than the value of the previous Standard_IA.
The value of days transitioning to Glacier Deep Archive must be at least 30 more than the value of the previous Glacier Instant Retrieval.
