Overview

Amazon Simple Storage Service. The S3 service can be integrated and exposed externally via the Amazon API Gateway.

Bucket

The Amazon S3 data model is a flat structure: you create a bucket, and the bucket stores objects. There is no hierarchy of subbuckets or subfolders; however, you can infer logical hierarchy using key name prefixes and delimiters. The Amazon S3 console supports a concept of folders. The console uses the key name prefixes and the delimiter ('/') to present a folder structure.

Objects

Each Amazon S3 object has data, a key, and metadata.

Key

Object Keys

The object key uniquely identifies the object in a bucket.

Metadata

Object Metadata

The object metadata is a set of key/value pairs. After the object was uploaded, the object metadata cannot be modified. The only way to modify the metadata is to make a copy of the object and set the metadata.
