I built a small AWS environment from scratch, including a VPC, public and private subnets, route tables, and EC2 instances with least privilege security groups. I emphasize that the distinction between public and private subnets lies in their route tables. I invite viewers to share their thoughts or suggestions on tightening the design further in the comments. This is part of my ongoing journey into cloud engineering and security.
