Deployment

1. Ensure you have Terraform installed
2. Configure AWS credentials
3. Run terraform init to initialize the working directory
4. Run terraform plan to preview the deployment
5. Run terraform apply to create the infrastructure

Testing

Use the ping_test.sh script to verify connectivity to all deployed instances.

Cleanup

When finished, run terraform destroy to remove all resources and avoid ongoing AWS charges.
