A bucket is a fundamental concept in AWS S3. To store anything in S3, you have to do so via a bucket. In this short blog, we will guide you on how you can create an S3 bucket in AWS. 

However, before we move to the meat of the matter, some basics first. Let’s start! 

What Is an AWS S3 Bucket? 

It is a container for storing images, files, documents, etc. In AWS, a bucket cannot exist inside another bucket. Also, a bucket has no limit to the number of objects it can hold. Bucket ownership is not transferable, and only the bucket owner can delete it. 

On this note, let’s create an S3 bucket in AWS Console followed by the CLI.
