🚀 Quick Start

1. Initialize Terraform

cd terraform
terraform init

2. Review the configuration

terraform plan

3. Deploy the infrastructure

terraform apply

🏗️ Architecture Overview

This Terraform configuration creates a complete VPC Lattice demonstration environment:

3 VPCs: Client, App1, and App2 VPCs for multi-VPC communication
EC2 Instances: Web servers and notification services
ECS Fargate: Containerized analytics service
VPC Lattice: Service network connecting all services
Lambda Functions: Serverless components

📋 Prerequisites

AWS CLI configured with appropriate permissions
Terraform >= 1.3
AWS Provider >= 6.0

📊 Outputs

After deployment, you'll get:

VPC IDs and CIDR blocks
EC2 instance details
ECS service endpoints
VPC Lattice service network information

🧹 Cleanup
