AWS Scenario 2 Terraform Module

AWS Scenario 2 Terraform Module

This module provides an example implementation of AWS scenario 2 via Terraform.

Example infrastructure consist of:

• 1 production database
• Multiple production/test instances
• 1 Elastic Load Balancer in front of production instances
• 1 test database
• 1 private and 1 public subnet
• 1 NAT instance
• 1 Internet Gateway instance
