To integrate an AWS S3 bucket with a CDN, you’ll need to reference the S3 bucket’s endpoint or the specific object URLs. These allow the CDN to fetch and cache the content hosted in your S3 bucket.

What You Need  

1. S3 Bucket Endpoint  

This is the base URL for accessing your entire S3 bucket.

Format: http://[bucket_name].s3.amazonaws.com/

Example: http://202533521498.s3.ap-south-1.amazonaws.com/

Use this when pointing a CDN to the whole bucket.

2. Object URL  

Each file or object stored in the bucket has its own direct URL.

Format: https://[bucket_name].s3.amazonaws.com/[object_key]

Example: https://202533521498.s3.ap-south-1.amazonaws.com/eye.jpeg

Use this when linking or caching specific files.

Where to Find These URLs  

Bucket Overview  

• Go to the S3 Console.

• Click on the bucket name.

• You’ll find the bucket endpoint in the Overview section.

Allow Public Access to the Object URL  

Configure permissions and access settings in Amazon S3 to allow public access to a specific object via its URL

Example  

Bucket Name: 202533521498
Object Key: eye.jpeg

Object URL:
https://202533521498.s3.ap-south-1.amazonaws.com/eye.jpeg

This is the URL you would provide to the CDN or use in your website/app.

Next Steps  

Once you have the correct URL:

1. Add it to your CDN origin settings.

2. Configure your cache rules and custom domains if needed.

3. Test by accessing the content via your CDN endpoint.
