What is Amazon S3?

Amazon S3 (Simple storage service) is a highly scalable, durable, cloud-based storage platform allowing users to put in and take out all the data they need regardless of the data size anywhere on the web. In contrast to block or file storage, S3 is based on an object storage architecture, i.e. files (so-called objects) are stored within containers called buckets. Besides a data, each object includes the metadata, which is why it can be used in a great variety of applications including backups, hosting media, static content on websites, data housing in data lakes, and so on.

Why is S3 Important?

Scalability: You do not need to think about the lack of space, S3 expands with your needs.

Availability and Durability: Information stored in S3 gets replicated in several devices and data centers in one region of the AWS and can be made durable with 99.99999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999

Security: S3 has access permissions and encryption to secure your files in a granular manner.

Ease: Upload and download files on AWS Console, CLI, SDKs, or through REST API.

Key Concepts:

Bucket: The main unit of data in S3 a file resides in a bucket.

Object: This can include any file located in an S3 bucket, its metadata and key.

permissions: Grant access to or manipulate your data by users, IAM policies, and bucket access control.
