What is AWS S3?

Amazon S3 (Simple Storage Service) provides object storage, which is built for storing and recovering any amount of information or data from anywhere over the internet. It provides this storage through a web services interface. While designed for developers for easier web-scale computing, it provides 99.999999999 percent durability and 99.99 percent availability of objects. It can also store computer files up to 5 terabytes in size.

AWS Buckets and Objects

An object consists of data, key (assigned name), and metadata. A bucket is used to store objects. When data is added to a bucket*8, Amazon S3 creates a unique version ID and allocates it to the **object.

How Does Amazon S3 work?

First off, a user creates a bucket. When this bucket is created, the user will specify the region in which the bucket is deployed. Later, when files are uploaded to the bucket, the user will determine the type of S3 storage class to be used for those specific objects. After this, users can define features to the bucket, such as bucket policy, lifecycle policies, versioning control, etc.
