AWS Cloud Practitioner: Domain Name System (DNS)

In this short series, I outline the notes that I took while preparing for the AWS Cloud Practitioner exam.

These are my personal notes that I have made while working through the A Cloud Guru exam practitioner course. They are in no way official notes from AWS.

I would advise you that if you do use my notes to help you revise for this exam, that you use them as a supplement to the most recent information in the White PapersExam Guide and go over your knowledge with practice exam papers.

What is DNS?

  • Route53 is Amazon’s DNS Service.
  • DNS (domain name system). Way that computer’s to resolve domain names to individual IP addresses
  • Can be used to redirect traffic all around the world
  • You buy (register) domains in AWS via Route 53. Named after the famous Route 66 highway in America but it’s called 53 because that’s the port that’s used(?)
  • If you buy a domain, make sure you have an S3 bucket with the same name
    and set up static website hosting on the bucket and set up a bucket policy (don’t forget to update the Amazon Resource name!)
  • May take about 3 hours to create the new domain. Once it’s registered, you’ll receive an email and it will appear in Hosted Zones”
  • DNS is global, similar to S3

Configure your DNS

  • Create a record set
  • Make it an Alias record e.g. this will mean that it’s a naked domain (there’s no www just kayleigholiver.com)
  • Select your Alias Target. The S3 bucket needs to have the same name as the DNS record
