This Terraform project is intended to be used as a template in a demonstration or to build a test environment.
What it does is creates an infrastructure composed of application VPCs, Shared Services VPC, Transit Gateway, and protect them with an auto-scaling group of CloudGuard gateways by using the newly AWS GWLB service.
These applications will have then the East-West and Outgoing traffic protected by CloudGuard Instances.
The following diagram is based on the Architecture N°2 design of Check Point GWLB in AWS.

The project creates the following resources and combines them:
- Spokes VPCs: Application VPCs with testing EC2s
- Service VPC: Single VPC dedicated to host VPC Endpoints
- Security VPC: Single VPC dedicated to host the CloudGuard gateways ASG
- Transit Gateway: Transit Gateway to connect the different VPCs
- Transit Gateway Config: Transit gateway attachments, and routing configuration
- GWLB Service: In the security VPC with its endpoint
- GWLB Auto-Scaling Group: Attached to the GWLB service to provide security enforcement
- Private Route53 Zone: Used to share VPC Endpoints hosted in the Service VPC
- VPC Endpoints and host registration: Used to access EC2 / ECR / RDS / CloudFormation services privately
The only thing that you need to do is change the terraform.tfvars file located in this directory.
