S3 Storage Classes

AWS provides different storage classes based on access frequency and cost.

1. Standard: Frequently accessed data.
2. Intelligent-Tiering: Automatically moves data between tiers to save costs.
3. Standard-IA (Infrequent Access): Lower cost, but retrieval fee.
4. One Zone-IA: Cheaper, but stored in only one AZ.
5. Glacier Instant Retrieval: Millisecond retrieval for archived data.
6. Glacier Flexible Retrieval: Minutes to hours retrieval.
7. Glacier Deep Archive: Lowest cost, 12 hours retrieval.

Lifecycle Rules:

Automate the transition between classes or deletion of objects to save money (e.g., Move to Glacier after 30 days).
