Different Storage tiers in Amazon S3 are as follows:
- S3 Standard: In this tier, S3 supports durable storage of files that become immediately available. This is used for frequently used files.
- S3 Standard -Infrequent Access (IA): In this tier, S3 provides durable storage that is immediately available. But in this tier files are infrequently accessed.
- S3 Reduced Redundancy Storage (RRS): In this tier, S3 provides the option to customers to store data at lower levels of redundancy. In this case data is copied to multiple locations but not on as many locations as standard S3.
