Features (1) ›
  • Immediate object transitions to S3 Standard-IA and One Zone-IA

    Amazon S3 has removed the 30-day minimum retention requirement for transitioning objects to S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) from S3 Standard. This enables cost savings for data that becomes less frequently accessed soon after creation.

Enhancements (2) ›
  • Reduced storage costs for infrequently accessed data

    S3 Standard-IA and S3 One Zone-IA now offer up to 40% lower storage costs compared to S3 Standard while maintaining millisecond access. This makes them suitable for workloads such as backups, log analytics, and compliance where data access patterns are predictable.

  • Flexible S3 Lifecycle rule configuration

    Users can now create new S3 Lifecycle rules to transition objects to S3 Standard-IA and S3 One Zone-IA as soon as 0 days after creation. Configuration is available through the S3 console, AWS CLI, and SDKs.
