Learn to put a real site on a real domain, securely and reliably. You will map how DNS resolves names to addresses, register and delegate a domain through Route 53, issue and validate TLS certificates with ACM, and place a health-checked Elastic Load Balancer in front of multiple instances so traffic is distributed and encrypted end to end.

Name resolution — from a URL to an IP address — free to watch, no account needed.
What you'll learn
- Put a site on a domain, securely and reliably, end to end
- Explain how DNS resolves a name and choose the right record type (A, AAAA, CNAME, MX, TXT)
- Register a domain and delegate it to a Route 53 hosted zone
- Issue and DNS-validate a TLS certificate with ACM and serve HTTPS
- Distribute traffic across healthy instances with an Elastic Load Balancer and health checks
