This diagram models a multi-instance EC2 deployment inside a single AWS VPC, where: • Each named node (Chandler, Mesa, Gilbert, Scottsdale, Phoenix, Peoria, Queen Creek) represents an EC2 instance • Instance families and sizes (t3.medium, m5.4xlarge) map directly to AWS EC2 instance types • Operating systems (Ubuntu, Windows Server 2022, RHEL 9) represent AMI selections • The central OS blocks represent standardized AMI baselines reused across multiple EC2 instances This is essentially a logical EC2 topology view, not a network or security view.
