5.3 VPC & Networking for the IMS System

VPC & Networking for the AI Production Management System

In this module, you design the network foundation for the AI Production Management System.

You will map the system architecture into a single VPC (for example vpc-ims, CIDR 12.0.0.0/16) with two public and three private subnets spread across Availability Zones ap-southeast-1a and ap-southeast-1b, and see where the Application Load Balancer, ECS services, and RDS live.

Learning goals

  • Understand how the IMS architecture fits into an AWS VPC with public and private subnets.
  • Place ALB, ECS tasks, and RDS into appropriate subnets and Availability Zones.
  • Prepare the network so that later modules (ECS, RDS, S3/CloudFront, messaging) can be deployed securely.
