What AWS object storage service organizes data in buckets?

Amazon S3 is the AWS object storage service that organizes data in buckets.

S3 stands for Amazon Simple Storage Service. It stores data as objects, with each object containing content, metadata, and a user-defined key. Buckets provide the top-level containers for those objects, while applications and users access them through the AWS console, APIs, command-line tools, or SDKs.

AWS launched S3 in the United States on March 14, 2006. Its design separated storage from traditional server filesystems, making it useful for websites, backups, archives, software distribution, data lakes, and disaster recovery. S3 can store many kinds of data rather than only documents or media files.

A common mix-up is treating S3 as a virtual disk. Amazon EBS provides block storage for computers such as EC2 instances, while S3 is accessed as an object store. Amazon S3 also is not Amazon Glacier, although S3 includes Glacier storage classes intended for lower-cost archival workloads.
