Previously, this blueprint used Route53 records associated with a static web hosting-enabled S3 bucket. The trade-off of this pattern was it only supports HTTP protocol. Red flag 🚩

Nowadays, there are much better options using Amazon CloudFront and CloudFront function. It's still serverless and supports HTTPS natively. It also enables new capabilities thanks to the newly released KeyValue Store feature in CloudFront.

This revised version will let you redirect subdomains to any other top-level domain, subdomains or URL.

• URL Redirect: Redirect multiple source subdomains to target URLs
• Easy URLs Management: Manage target URLs directly using the CloudFront AWS Console

Examples:

• blog.zoph.io -> https://zoph.me
• asd.zoph.io -> https://awssecuritydigest.com
• book.zoph.io -> https://calendly.com/zophio/30min-meeting/

ℹ️ The following assets will be deployed to your AWS account.

1. CloudFront Distribution
2. CloudFront Function
3. CloudFront KeyValueStore
4. S3 Buckets
5. S3 Bucket Policy
6. Route53 Records
