The Intelligent Tiering storage class in Amazon S3 is designed to optimize costs by automatically moving data between two access tiers based on changing access patterns. When data is first uploaded, it is stored in the frequent access tier. If the access frequency drops and the data is deemed infrequently accessed, S3 automatically transitions it to the infrequent access tier after 30 days of inactivity.

This dynamic movement between tiers helps organizations save on storage costs while ensuring that frequently accessed data remains readily available, thus providing a balance between accessibility and cost-effectiveness. The automatic nature of this movement distinguishes Intelligent Tiering from other storage classes, which may require manual intervention to manage and optimize cost-effectiveness.

The other storage classes mentioned do not offer this level of automation. Some may require manual management or have fixed characteristics that do not adjust based on usage patterns.
