Chapter 6 of this blog post series will be all about Amazon’s object-based storage service, S3 and the Life-Cycle Management capabilities this service provides.

S3 Life-Cycle Management

What is Life-Cycle Management? After so many days transition to IA and then after 60 days transfer to Glacier for long term archival or just completely expire / delete the object.

• Create a bucket, then click management to add life cycle rule
• Automate transition to tiered storage
• Use a life cycle rule to automatically expire objects based on retention needs.
• You can configure “transition” for current version of objects or previous versions.
• The files must be over 128 kb in size in order to be allowed to transition.
• Configure expiration.
• Default expiration is 425 days from object creation
• Can be used in conjunction with versioning
• Can be applied to current versions and previous versions of objects

Following actions can now be done:

• Transition to the Standard – Infrequent Access Storage Class
  • 128kb and 30 days after the creation date
• Archive to the Glacier Storage Class
  • 30 days after the Infrequently Accessed (default)
• Permanently delete an object
• 30 days is the minimum value for transitioning to Infrequently Accessed Storage Class (128kb)
