Amazon S3 (Simple Storage Service) provides different storage tiers to optimize cost and performance based on the frequency of access to the stored data[1]. The storage tiers in AWS S3 include:

S3 Standard: This tier is designed for frequently accessed data and offers high performance and low latency. It is suitable for scenarios where data needs to be accessed frequently.

S3 Intelligent-Tiering: This tier automatically moves objects between two access tiers based on their usage patterns. It consists of a frequent access tier and an infrequent access tier. The objects that are accessed frequently are stored in the frequent access tier, while the objects that are not accessed as frequently are moved to the infrequent access tier. This allows for cost optimization as unused data is automatically moved to a lower-cost tier[1].

S3 Standard-IA (Infrequent Access): This tier provides a lower-cost storage option for data that is accessed less frequently. It is suitable for data that requires durable storage but does not require immediate access.

S3 One Zone-IA: Similar to S3 Standard-IA, this tier provides lower-cost storage for infrequently accessed data. However, it stores the data in a single availability zone, making it less resilient to zone failures compared to other storage tiers.

S3 Glacier: This tier is designed for long-term archival storage and offers significantly lower storage costs compared to other tiers. Data stored in S3 Glacier has a longer retrieval time, ranging from minutes to hours.

S3 Glacier Deep Archive: This tier provides the lowest-cost storage option for data that is accessed very rarely. It offers the longest retrieval time, ranging from hours to days, making it suitable for data that needs to be retained for compliance or regulatory purposes[1].

These storage tiers in AWS S3 allow users to choose the most appropriate storage option based on their access frequency requirements and cost considerations
