Route 53

Route

A Managed DNS service

• service for managing & registering domains
• forwards requests to services by using a custom domain

• Managing domains
  • By buying the domains
  • Transferring existing domains to AWS
  • Create co-hosted zones
    • configuration container of DNS records (routing configurations for a domain name)
    • stores the rules attached to the domain
• Managing DNS
  • Manage DNS entries, routing records, to control which requests should be forwarded to which service
    • ex.) you might want to forward incoming requests to a elastic load balancer
    • Create new records
      • could also add a subdomain
      • You need to add the IP in which the requests should be forwarded to (would make sense only if it had a fixed IP), or an Alias (which allows you choose an AWS service then a region)
  • Manage failover or create complex routing routes

Alias

• An Alias record in AWS Route 53 is a special type of DNS record that allows you to point your domain to an AWS resource (like an Elastic Load Balancer (ELB)), an S3 bucket, or a CloudFront distribution) without needing to use an IP address.
• Alias records avoid the need for fixed IP addresses since AWS services like ELB or CloudFront do not have static IPs.
• Ex) You create an A-type DNS record that uses an alias for routing traffic to an Application load balancer
