Description: The default storage class for frequently accessed data.
Durability: 99.999999999% (11 9s) across multiple Availability Zones.
Availability: 99.99% annually.
Use Case: Frequently accessed data such as active content, big data analytics, mobile and gaming applications.
2. S3 Intelligent-Tiering
Description: Automatically moves data between two access tiers (frequent and infrequent) based on changing access patterns, optimizing storage costs.
Durability: 99.999999999% (11 9s).
Availability: 99.9% annually.
Use Case: Data with unpredictable or changing access patterns where cost optimization is essential.
3. S3 Standard-IA (Infrequent Access)
Description: Lower-cost storage for data that is accessed less frequently but requires rapid access when needed.
Durability: 99.999999999% (11 9s).
Availability: 99.9% annually.
Use Case: Long-term storage, backups, disaster recovery, and data that is infrequently accessed.
4. S3 One Zone-IA (Infrequent Access)
Description: Lower-cost option for infrequently accessed data stored in a single Availability Zone, offering less resilience than Standard-IA.
Durability: 99.999999999% (11 9s) in a single Availability Zone.
Availability: 99.5% annually.
Use Case: Infrequently accessed data that can be recreated or replicated easily, such as secondary backups or data that doesn’t require multi-AZ resilience.
