There are mainly two types of Object Lifecycle Management actions in

Amazon S3.

1. Transition Actions: These actions define the state when an Object

transitions from one storage class to another storage class. E.g. a new

object may transition to STANDARD_IA (infrequent access) class

after 60 days of creation. And it can transition to GLACIER after 180

days of creation.

2. Expiration Actions: These actions specify what happens when an

Object expires. We can ask S3 to delete an object completely on

expiration.
