The problem

Your shop’s address is 203.0.113.9. Nobody remembers numbers. And shoppers in Kota Kinabalu wait longer than those next door. What helps first?

  • The browser asks the nearest kiosk
  • The shopper types kedai.example
  • Route 53 answers with an address

      You did it!

      You can now explain how shoppers find you, and why a copy can be old.

      Go deeper (optional)

      Where the story breaks: a VPC is not land. You can make several, and none costs rent. Wings (Availability Zones) are separate buildings, kilometres apart. And a security group guards each server, not a shared door.

      Real rep (optional): follow the CloudFront guide for a private S3 bucket.
