How to Host a Public Website on AWS S3
Amazon Web Services (AWS) Simple Storage Service (S3) is an excellent option for hosting static websites. With AWS S3, you can easily store and serve static files like HTML, CSS, JavaScript, and images for free or at a low cost depending on your usage. In this guide, we’ll walk you through the steps to host a public website using AWS S3, including setting up your bucket and configuring access permissions.
Step 1: Create an S3 Bucket
-
Log into AWS Console: First, log in to your AWS account.
-
Navigate to S3: In the AWS Management Console, go to the S3 service.
-
Create a Bucket:
-
Click Create bucket.
-
Give your bucket a unique name (e.g.,
my-public-website) and select a region closest to your target audience. -
Leave other settings as default, but make sure to disable Block Public Access so your website can be publicly accessible.
-
Step 2: Upload Your Website Files
-
Upload Files: Once your bucket is created, click on the bucket name to open it.
-
Add Files: Click on the Upload button to upload your website files (HTML, CSS, JavaScript, images, etc.).
-
Set Permissions: You’ll be asked to set permissions during the upload process. Ensure that the files are set to Public Read so users can access them.
Step 3: Enable Static Website Hosting
-
Go to Properties: Inside your S3 bucket, click on the Properties tab.
-
Static Website Hosting:
-
Scroll down to the Static website hosting section.
-
Select Enable and specify the Index document (usually
index.html). -
Optionally, specify an Error document (like
404.html) for better user experience when a page is not found.
-
-
Save Changes: After enabling static website hosting, click Save changes.
Step 4: Set Bucket Permissions for Public Access
To make your website accessible to everyone, you need to set the correct permissions on the S3 bucket.
-
Bucket Policy:
-
Go to the Permissions tab in your S3 bucket.
-
Click on Bucket Policy and enter the following policy, replacing
my-public-websitewith your actual bucket name:
-
-
Save the Policy: Click Save to apply the policy.
Step 5: Access Your Website
After the steps above, your website should be live. To access it:
-
Get the Website URL: In the Properties tab under Static website hosting, you’ll see a Bucket website endpoint.
-
Test Your Website: Open the URL in a browser to see your public website live.
Bonus Tip: Using a Custom Domain with AWS S3
If you want to use a custom domain (e.g., www.yourdomain.com) instead of the S3 endpoint, you can set up a custom domain with Amazon Route 53 (or any DNS provider) and point it to your S3 bucket.
-
Create a CNAME Record: In your DNS provider’s dashboard, create a CNAME record that points to your S3 bucket’s website endpoint.
-
Update S3 Bucket Configuration: Go back to your S3 bucket, and in the Static website hosting section, enter your custom domain under the Bucket website endpoint.
Conclusion
AWS S3 is a powerful, cost-effective way to host a static website. With minimal configuration, you can get your website online and running with excellent scalability. By following these simple steps, you can leverage AWS to host your website efficiently while maintaining full control over your content.
