  • We want to fully scale vertically and horizontally, no downtime
  • Let’s go through the Solutions Architect journey for this app
  • Let’s see how we can proceed!

In this lecture we’ve discussed…​

  • Public vs Private IP and EC2 instances
  • Elastic IP vs Route 53 vs Load Balancers
  • Route 53 TTL, A records and Alias Records
  • Maintaining EC2 instances manually vs Auto Scaling Groups
  • Multi AZ to survive disasters
  • ELB Health Checks
  • Security Group Rules
  • Reservation of capacity for costing savings when possible
