Amazon Simple Storage Service or Amazon S3 is a service designed to house storage for the internet. Amazon offers 6 different storage classes: S3 Standard-IA, S3 Glacier, One Zone-IA and S3 Deep Archive. The storage class is typically used for frequently accessed data, but the cost per GB is high. S3 Intelligent-Tiering class automatically moves data between S3. Glacier is ideal for backups, archiving, and any long-term infrequently accessed data. Glacier objects aren’t immediately available.
