terraform-aws-multi-az-subnets
DEPRECATED (use cloudposse/terraform-aws-dynamic-subnets instead): Terraform module for multi-AZ public and private subnets provisioning
A common architecture is to deploy substantially identical sets of resources across multiple regions for high availability. I've looked into this, and it seems that Terraform simply doesn't have a solution for multiregion deployments. Issue 24476 has a lengthy discussion about the technical details, but few practical suggestions for overcoming the limitations. There are a handful of posts on sites such as medium.com offering suggestions, but frankly many of these don't really solve the problems.
