Topics

DNS

Part of the Cloud Computing Roadmap.

Summary

The Domain Name System translates human-readable domain names into IP addresses — understanding record types (A, CNAME, MX, TXT) and cloud-managed DNS services (Route 53, Cloud DNS) is essential for deploying any web-facing service.

How to Learn This

  • 1Run dig or nslookup on a domain to see DNS resolution in action.
  • 2Explore a managed DNS service's console (Route 53 or equivalent) to see how records are configured.
  • 3Understand DNS propagation delay and why DNS changes aren't instant everywhere.
