 Using Amazon S3

This section covers how to set up and use Amazon S3 to store, manage, and serve content remotely on your website.

Using Amazon S3Amazon S3 is an affordable and almost limitless cloud storage solution that lets you store your files and large amounts of data, including images, media files, and website backups securely and embed these in your web content.

In this lesson, we provide an overview of the Amazon S3 service, show you how to set up an Amazon S3 account for your business, and how to upload files to S3 directories.


Why Store Your Site’s Content In The Cloud?

Hosting and streaming large media files on your website (e.g. videos) can be expensive and sometimes even complicated.

When it comes to storing files to be used as content on your website, you have a number of options.

For example, if you use WordPress as a CMS,  you can use the built-in WordPress Media Library to store and serve images, videos, audio, and downloadable files in your content.

While the WordPress Media Library is a great tool for storing media files used in your content, these files are stored on your own server, and depending on your web hosting setup, these can take up excessive space and cause issues with site performance, or exceed your data or bandwidth allowance.


Note: In some cases, using the WordPress Media Library is necessary. For example, if you are adding featured images to posts or pages, or product images to a  WooCommerce-powered eCommerce store.


Another option is to upload and stream videos from a free video hosting site like YouTube, display images stored on Flickr, etc., and embed these into your content.

The problem with storing your web content files on free sites, however, is that you are not in control of your content. If, for example, the site changes its policies, this could have a significant effect on how your site can access your files and potentially even disrupt your entire business.

Given the above options and their respective challenges, a viable alternative is to serve content on your site that is stored and streamed from the cloud.

Many companies offer inexpensive cloud storage solutions that allow you to host and embed media, files, and documents into your website content.

Some of these solutions include Google Drive, DropBox, Amazon, and others.

Enter Amazon S3…

What Is Amazon S3?

Amazon Simple Storage Service (Amazon S3) is an affordable, secure, and reliable cloud storage solution service from Amazon Web Services (AWS) that you can use to store and retrieve any amount of data, at any time, from anywhere on the web.

Amazon S3 lets you share, distribute and download zip, PDF, audio, and video files, and stream videos on your site without consuming a large amount of bandwidth or straining your server’s resources.

Essentially, you’re using Amazon’s servers to store as much information as you want (videos, audio files, images, large files, etc.) at very little cost (you’ll pay only a few dollars per month for large amounts of data use), making this an ideal solution for using media content on your website.

The video below provides an overview of the Amazon S3 service:

Note: Amazon S3 is one of several applications that Amazon offers in its stable of products, so it’s important not to confuse Amazon S3 with Amazon AWS (i.e. the entire suite of services).

Benefits Of Using Amazon S3

Amazon S3 helps to address some of the biggest technical challenges many businesses face managing content on their websites, like site speed, security, and bandwidth cost.

Here are some of the benefits of using Amazon S3 to host your site’s content:

Improve Site Speed

When you host images, videos, and other heavy bandwidth items like large downloadable files on your own server, the more simultaneous traffic you have (i.e. many users visiting your site at the same time), the slower your pages load on your visitors’ browsers.

If you have spikes in traffic, this extra load can even crash your site.

One of the benefits of storing content remotely on the cloud is that uploading images, videos, and other large bandwidth-consuming files to Amazon S3 instead of your own server allows thousands of visitors to access your information without slowing down your site because the files are being delivered from Amazon’s servers, not yours.

Storing large-sized files or a large number of files in the cloud and streaming these in your content remotely can help to improve your site’s performance.

Host Large-Sized Files

Imagine having a product launch where lots of customers try to download a number of large zip files hosted on your server. Your server could crash, support tickets would start piling up and what should be a very happy day would quickly turn into a nightmare.

If you host your images, videos, and other downloadable files on Amazon S3, your visitors will not experience your site slowing down, buffering, or crashing due to excessive bandwidth consumption.

You could have 100, 1,000, or 10,000 people downloading your zip files simultaneously without any problems.

Save Money Streaming Your Content

Another benefit of using Amazon S3 is how much money you can save. Amazon S3 is an “online scalable (simple) storage service,” which means that it’s essentially a hard drive in cyberspace with unlimited storage – you only pay for what you use.

When Amazon launched S3 back in 2006 (2007 in Europe) they began by charging only 15 cents per gigabyte, and this price has been getting cheaper over time. Currently, it’s in the range of around 3 cents per Gb. This means better service and more savings for you.

Storing large-sized files or a large number of files in the cloud and streaming these in your content remotely can help to keep your web hosting costs down.

Save Time Managing Your Media Content

One of the many benefits and advantages of using a remote storage service like Amazon S3 to add media to your content instead of serving those files from the WordPress Media Library or a free media-hosting site like YouTube is the amount of time you can save managing your media content.

For example, let’s say that you decide to change an image that you have used multiple times throughout your site.

Instead of searching and replacing every instance of that image on your entire site, you can simply upload the new image file and overwrite the old file in your Amazon S3 account. All instances of that file will then automatically update on your site.

There are many advantages to storing your website’s content files on the cloud.

Additionally, if you use WordPress, adding media files like images and videos to your content is as simple as copying and pasting the file’s link wherever you would like that file to display.


All images used on this site (except for the featured images containing the titles of our course modules and lessons) are streamed from an Amazon S3 account.

You need to set file permissions for users to view or access files stored on Amazon S3.


You do not have to enable permissions on your files if you don’t plan to share your files with other users or want to keep these files private (e.g. backup files).

How To Upload And Share Files On Amazon S3

After setting up your Amazon S3 account, you can upload files from your hard drive to your Amazon AWS S3 buckets. These files will be stored as an S3 object.

An object consists of the uploaded file and its metadata. You can upload any kind of file you like to an S3 bucket (e.g. images, videos, audio files, backups, data, etc.)
