Introduction to Amazon S3

AWS S3, or Simple Storage Service, is a storage solution provided by AWS that allows you to store and retrieve any amount of data from anywhere on the web. You can think of it as an online storage space you can access from any device with an internet connection. S3 is a reliable and flexible service that can be used for a wide range of storage needs, including storing text, images, audio files, and videos.

It works by storing data as objects within buckets. A bucket is a logical container for your data, similar to a folder in a traditional file system. An object is a file, and it is identified by a unique key.

How do you use AWS S3?

To use S3, you first need to create a bucket and specify a bucket name and an AWS Region. Then, you can upload your data to the bucket as objects. You can store any type of data in an object, such as text, images, audio files, videos, and more.

S3 provides features that you can use to customize the service for your specific needs. For example, you can use Versioning to keep multiple versions of an object in the same bucket, which allows you to restore objects that are accidentally deleted or overwritten.

There are a TON of other ways to customize S3 for unique use cases (seriously). One advanced example is shown below from the AWS S3 user guide:

S3 Object Lambda – Add your own code to S3 GET, HEAD, and LIST requests to modify and process data as it is returned to an application. Filter rows, dynamically resize images, redact confidential data, and much more.

By default, buckets and the objects in them are private and can only be accessed if you explicitly grant access permissions. You can use bucket policies, Identity and Access Management (IAM) policies, access control lists (ACLs), and S3 Access Points to manage access to your data.
