https://fortinetcloudcse.github.io/fortinet-ui-terraform/3_example_templates/index.htmlIntroduction The FortiGate Autoscale Simplified Template consists of three complementary Terraform templates that work together to deploy FortiGate architectures in AWS: existing_vpc_resources (Deploy First): Creates supporting infrastructure including management VPC, Transit Gateway, spoke VPCs, and deployment mode configuration autoscale_template (Choose One): Deploys FortiGate AutoScale group with Gateway Load Balancer for elastic scaling ha_pair (Choose One): Deploys FortiGate Active-Passive HA Pair with FGCP for fixed-capacity deployment This modular approach allows you to:Hugoen-UShttps://fortinetcloudcse.github.io/fortinet-ui-terraform/3_example_templates/3_1_existing_vpc_resources/index.htmlMon, 01 Jan 0001 00:00:00 +0000https://fortinetcloudcse.github.io/fortinet-ui-terraform/3_example_templates/3_1_existing_vpc_resources/index.htmlOverview The existing_vpc_resources template is a Terraform template designed for testing, demonstration, and lab environments. It creates supporting infrastructure including management VPC, Transit Gateway, spoke VPCs, and configures the deployment mode for either AutoScale or HA Pair FortiGate deployments. Warning Deploy this template FIRST before deploying autoscale_template or ha_pair. You must choose a deployment mode during configuration. Deployment Mode Selection When deploying existing_vpc_resources, you must choose ONE deployment mode:https://fortinetcloudcse.github.io/fortinet-ui-terraform/3_example_templates/3_2_autoscale_template/index.htmlMon, 01 Jan 0001 00:00:00 +0000https://fortinetcloudcse.github.io/fortinet-ui-terraform/3_example_templates/3_2_autoscale_template/index.htmlOverview The autoscale_template is the required Terraform template that deploys the core FortiGate autoscale infrastructure. This template is used for all deployments and can operate independently or integrate with resources created by the existing_vpc_resources template. Info This template is required for all deployments. It creates the inspection VPC, FortiGate autoscale group, Gateway Load Balancer, and all components necessary for traffic inspection. Documentation Structure This template documentation is organized into focused sections:https://fortinetcloudcse.github.io/fortinet-ui-terraform/3_example_templates/3_3_ha_pair/index.htmlMon, 01 Jan 0001 00:00:00 +0000https://fortinetcloudcse.github.io/fortinet-ui-terraform/3_example_templates/3_3_ha_pair/index.htmlIntroduction The ha_pair template deploys a FortiGate Active-Passive High Availability pair using FortiGate Clustering Protocol (FGCP) in AWS. Unlike the autoscale_template which uses Gateway Load Balancer for elastic scaling, the HA Pair provides a fixed-capacity deployment with native FortiOS failover capabilities. Key Features Active-Passive HA: One FortiGate active, one standby with automatic failover Session Synchronization: Maintains TCP sessions during failover for stateful inspection FGCP (FortiGate Clustering Protocol): Industry-standard clustering with unicast heartbeat AWS Native Failover: Automatic EIP and ENI reassignment via AWS API No GWLB Required: Uses native AWS routing without additional load balancer costs VPC Endpoint: Private AWS API access for failover operations Transit Gateway Integration: Automatic TGW route table updates Prerequisites Warning The ha_pair template requires existing_vpc_resources to be deployed first with HA Pair Deployment mode enabled.
