NEW Dual Stack Full Mesh Trio!

Dual Stack Full Mesh Trio Demo

• Compose a dual stack Full Mesh Transit Gateway across 3 regions using Tiered VPC-NG (at v1.0.4), Centralized Router (at v1.0.4) and Full Mesh Trio (at v1.0.1) modules.
• Includes an VPC peering examples within a full mesh configuration used high traffic workloads to save on cost for inter-region using the VPC Peering Deluxe module (at v1.0.1).
• Requires IPAM Pools for IPv4 and IPv6 cidrs.
• Validate connectivity with Route Anlyzer.

Dual Stack TNT Architecture!

Dual Stack Terraform Networking Trifecta Demo

• Compose a dual stack hub and spoke Transit Gateway using Tiered VPC-NG (at v1.0.4) and Centralized Router (at v1.0.4) modules.
• Requires IPAM Pools for IPv4 and IPv6 cidrs.
• Validate connectivity with EC2 instances.

Notes

• Sometimes I'll blog about ideas at jq1.io.
• All modules are first developed in the terraform-modules repo.
• The most useful modules are published to the Public Terraform Registry.
• All demos include an example of generating security group rules for inter-region and cross-region VPCs for each TGW configuration.
  • Intra VPC Security Group Rule (IPv4 only)
  • Super Intra VPC Security Group Rules (IPv4 only)
  • Full Mesh Intra VPC Security Group Rules (IPv4 only)
  • IPv6 Intra VPC Security Group Rule (IPv6 only, for use with dual stack VPCs)
  • New IPv6 Full Mesh Intra VPC Security Group Rules (IPv6 only, for use with dual stack VPCs)
  • TODO: Mega Mesh Intra VPC Security Group Rules
• The Centralized Router module is an implementation of the AWS Centralized Router concept but without VPN Gateway or Direct Connect, only VPCs.
• Available AZs (a,b,c etc) in a region are different per AWS account (ie. your us-west-2a is not the same AZ as my us-west-2a) so it's possible you'll need to change the AZ letter for a VPC if the provider is saying it's not available for the region.
• There is no overlapping CIDR detection inter-region or cross-region so it's important that the VPC's network and subnet CIDRs are allocated correctly.
