Understand Lifecycle Rules

As per the AWS S3 pricing model, the cost is incurred on the amount of data stored in an S3 bucket. Therefore, to optimize the cost, it becomes necessary to configure a lifecycle rule that allows either the transition of objects to a different cost-effective storage class or their expiration after a specific time period.

Transition objects

Using an S3 lifecycle rule, it’s possible to move bucket objects to a different storage class based on the requirements and access patterns.

For example, if a certain bucket contains objects that are very infrequently accessed after a period of time, it would be better to move objects to the S3 Standard-IA storage class.

In case the access patterns are unknown, objects can be transitioned to the S3 Intelligent-Tiering storage class for cost optimization.

However, it’s important to note that there are certain constraints that apply to the object transition lifecycle rules.
