Amazon Web Services (AWS) is the leading provider of cloud computing services and hosting solutions. Among the vast number of services offered by AWS, the Simple Storage Service (S3) is one of the mostly widely used. This storage service offers high reliability, durability, scalability, and availability when compared to any other storage service.

In this course, you’ll learn about AWS S3 and its features in detail. Not only will you learn how AWS S3 works, you’ll also get hands-on experience with AWS’ security features and how to monitor and manage an AWS-hosted storage solution. By the end of this course, you will be able to use the console and command-line interface (CLI) to perform complex operations and host a static website using S3.

A Programmer’s Guide to AWS S3

Before we dive into hands-on learning with S3, we need to know some basic naming rules to follow while creating an S3 bucket.

We already discussed in a previous lesson that bucket names must be globally unique and DNS compliant. Let’s see what these rules are in detail.

# Bucket naming rules

- The bucket name must be globally unique across AWS.
- The name must be 3–63 characters long.
- The name can consist only of lowercase letters, numbers, dots (.), and hyphens (-).
- The name must begin and end with a letter or number.
- The name must not be formatted as an IP address, like 192.54.54.101.
- The name must not start with the prefix “_xn–_.”


It’s recommended to use the dot (.) in a bucket name only if the bucket is supposed to be used for static web hosting.

After bucket creation, the bucket name can’t be changed. So, we have to make sure to give it a name as per our requirements.

# Valid bucket names

- `my-s3-bucket`
- `test-bucket-dev`
- `devbucket1`


# Invalid bucket names
- `testBucket`
- `dev-test.`
- `my_s3_bucket`
