1. Details of each Class

1.1. S3 Standard

• Purpose: General-purpose storage for frequently accessed data.
• Performance: Low latency and high throughput.
• Cost:
  • Storage Fee: Per-GB stored.
  • Retrieval Fee: No retrieval fees apply.
  • Monitoring and Auto-Tiering Fees: None.
• Use Cases: Websites, mobile applications, and data analytics.

1.2. S3 Intelligent-Tiering

• Purpose: Optimizes storage costs for data with unpredictable access patterns.
• Performance: Low latency; similar retrieval times to Standard.
• Cost:
  • Storage Fee: Per-GB stored, slightly higher than Standard.
  • Retrieval Fee: Fees apply for infrequent access (per-GB).
  • Monitoring and Auto-Tiering Fees: Monthly monitoring fee applies.
• Use Cases: Data with varying access patterns, such as analytics data.

1.3. S3 Standard-IA (Infrequent Access)

• Purpose: Cost-effective storage for infrequently accessed data.
• Performance: Low latency for infrequent access.
• Cost:
  • Storage Fee: Per-GB stored, lower than Standard.
  • Retrieval Fee: Fees apply for each GB retrieved.
  • Monitoring and Auto-Tiering Fees: None.
• Use Cases: Backup data and disaster recovery.

1.4. S3 One Zone-IA

• Purpose: Lower-cost storage for infrequently accessed data without multi-AZ resilience.
• Performance: Low latency for infrequent access.
• Cost:
  • Storage Fee: Per-GB stored, lower than Standard-IA.
  • Retrieval Fee: Fees apply for each GB retrieved.
  • Monitoring and Auto-Tiering Fees: None.
