AWS Simple Storage Service (S3) is a storage service that can be used as storage on the internet. It allows us to download and upload any amount of data any time, with various use cases such as storing videos, images, documents, log files, assets (such as images, JavaScripts, and CSS) of a website, and so on.

S3 allows us to store our documents in private and public modes, which enables us to store secret data over S3 for personal use, as well as files that are publicly available. S3 uses object storage instead of flat file systems. Object storage is storage designed to store data as an object. An object contains data and metadata, allowing us to store unstructured data.

In this recipe, we will be creating an S3 object using the PUT operation and then we will retrieve that object with the GET operation. Amazon S3 stores our data as objects inside buckets.
