Amazon Simple Storage Service (Amazon S3) is a widely-used object storage service that offers industry-leading scalability, data availability, security, and performance. S3 has a variety of storage classes.

Key considerations when choosing Amazon S3 storage class include access frequency, performance (retrieval time), availability, durability, and cost. S3 Standard is ideal for frequently accessed data. S3 Standard-IA and One Zone-IA are cost-effective for infrequent access. Glacier, Glacier Flexible Retrieval, and Glacier Deep Archive offer substantial cost savings for long-term archival storage. Intelligent Tiering is beneficial for unpredictable access patterns, automating cost savings by transitioning data between tiers.
