Amazon S3– You will use Amazon S3 to create buckets, upload a sample website page, configure permissions so everyone can see the content, and then configure the buckets for website hosting. In this example, because you want to allow requests for both http://www.example.com and http://example.com, you will create two buckets; however, you will host content in only one bucket. You will configure the other Amazon S3 bucket to redirect requests to the bucket that hosts the content.

Setup Logging is an additional option available at the left, but you dont need that.

Amazon Route 53– You will configure Amazon Route 53 as your DNS provider. You will create a hosted zone in Amazon Route 53 for your domain and configure applicable DNS records. If you are switching from an existing DNS provider, you will need to ensure that you have transferred all of the DNS records for your domain.
All the steps in this example use example.com as a domain name. You will need to replace this domain name with the one you registered.
