This article will provide an in-depth introduction to AWS S3 — the secure, scalable, and super cheap storage service from Amazon Web Services.

If you have ever worked as a developer, you have likely come across file storage use cases. From simple images to large videos, uploading, storing, and accessing those files when you need them is always tricky.

The usual answer to file storage is to keep them on the same server where you host your web applications. But with the advent of serverless architectures and single-page applications, storing files on the same server is not a good idea.

You could argue that you can store files in databases. But trust me, it won’t be a pleasant experience.

So what’s another option?

What is S3?

Let’s look at AWS S3. S3 is an easy-to-use, scalable, and cheap storage service from Amazon. You can use S3 to store any amount of data for a wide range of use cases.

Static website hosting, data archival, and software delivery are a few general scenarios where S3 would be a perfect tool.

You can easily push and pull data with S3 using the AWS SDK. S3 also supports a number of popular programming languages, so you can use your existing stack and integrate S3 pretty easily.

S3 also offers a great user interface via the AWS console. You can use it to view the data pushed to S3 along with additional options such as security and version control.
