AWS Multi-Tier VPC Architect • 10.0.0.0/16

Cloud & VPC Architecture Blueprint

An interactive multi-AZ architecture model demonstrating defense-in-depth network segmentation.

Public Subnet
CIDR / IP Range:10.0.1.0/24 & 10.0.2.0/24
Availability Zone:Dual-AZ (us-east-1a & us-east-1b)
Route Table Rule:Local 10.0.0.0/16, Default via IGW
Security Group Ingress/Egress:Inbound: TCP 443/80 from 0.0.0.0/0 | Outbound: Port 8080 to App-SG
Architectural Role:

Handles SSL/TLS termination, performs continuous health checks, and evenly distributes client requests across backend app containers.

Current Active Traffic Simulation:
Internet → IGW → Public ALB → Private App Container (8080)
