Today’s information landscape is so vast that delivering valuable assets such as product catalogs and educational resources to your audience has become a cornerstone of modern business strategies. Amazon’s Simple Storage Service is a robust and secure cloud storage solution. It is also possible to make some data public. This feature is useful in many real-life situations, including hosting websites, sharing files and managing data. It’s my favorite feature to use. I send infographics, and other learning materials in my emails.

This tutorial will walk you through creating a public Amazon S3 Bucket, uploading your files, and setting them up for public access. We will also discuss the important elements of security to protect and maintain the integrity of your data.

Step One: Bucket Creation 

Create a bucket. A bucket is similar to a folder or directory. Select “Create bucket” from the Amazon S3 Console. Follow the instructions in order. Your bucket name must be unique throughout Amazon S3. Make sure it is unique and relevant. You can leave the default settings for most of these. Later, we will change them.

Step 2: Uploading files 

It’s now time to fill your bucket with content. Select your newly created bucket from the S3 console and click “Upload”. Then, click “Add Files”. You will be presented with a dialogue box that allows you to browse your computer to select the files to upload. Click “Start upload” once you have selected the files and watch them begin their journey into the cloud. Return to your bucket once your file is uploaded.

Step 3: Configuring public access 

Amazon S3 is set to keep buckets private by default. This is an important security measure. If you want to make your content available to everyone, certain settings will need to be adjusted. Navigate to the “Permissions tab” in your bucket settings. Uncheck all boxes in the “Block Public Access” section to set your bucket as “Objects Can be Public”. Remember that this does not make your files publicly accessible yet. You need to specify public accessibility at the file level, as we will explain later.

Step 5 – Setting File Access Control 

It’s now time to adjust the file-level permissions. To adjust file-level permissions, follow these steps:

  1. Navigate to your S3 bucket in the AWS console.
  2. Click on the file that you wish to edit.
  3. Click on the “Permissions tab” in the File Details view.
  4. Check the “Everyone” box under the “Access Control List” section to allow access to all users.
  5. You will see a list of permissions. Select “Objects”, then check the box next “Read”. Anyone can read or download a file by checking the box next to “Read” under the “Objects” category.
  6. Uncheck the “Write’ checkbox to ensure the security of the file and prevent unauthorized modifications. 
  7. Save your changes and repeat the process for all other files that you wish to configure.

Security considerationsPlease be aware that granting public access to your S3 bucket may pose security risks. This is especially true if the bucket contains sensitive data. Access control measures, such as a server API that handles authentication and requests, are a safer option. To prevent unauthorized changes to your bucket, only activate public access if necessary. Never allow public write access. This could prove to be a costly error, literally.

Share the Public Access URL 

You can share the public URL easily with others once you’ve set up the permissions on your files. To find the URL, follow these steps:

  1. Navigate to your S3 bucket in the AWS console.
  2. Click on the file that you wish to share.
  3. You will find a section that displays the properties and metadata of the file in the details view.
  4. Find the “Object URL” (or “Public URL”) field. This field contains a URL that can be used for public access to the file.
  5. Copy the URL to share with others or embed it in your application or website.

Congratulations! Congratulations! You can easily share the public URL of your Amazon S3 bucket file. This URL allows others to view and access the content of the file without requiring any authentication or special permissions.

Amazon S3 Bucket is my personal favorite because of its ease of use and deployment. Other alternatives are available. While Amazon S3 may be a great solution, there are other options that might suit your needs. These include Google Cloud Storage and Azure Blob Storage. These platforms all offer similar security and functionality, but they may differ on pricing, interface, and integration options.

Amazon S3 offers a variety of storage options that are efficient, scalable and secure. This can help you reach your audience more effectively. While granting public access can be beneficial in some circumstances, it is important to know the risks associated with this to ensure that your data remains secure and intact. This guide will help you confidently share content with a worldwide audience while maintaining the security of your data.
