RANIARANIA Academy

Domains, DNS, HTTPS & Load Balancing

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.
