Dynamic AWS Security Groups with Terraform
summary
Shows how Terraform builds paired client/server security groups from a map of services using a 1/0 nomenclature, auto-creating per-service SGs and separate SG rules via a reusable security group services module. Demonstrates a live run that plans and applies 27 Terraform-managed resources (SGs + rules), supports cross-VPC SG references, notes AWS per-instance SG limits and raising quotas, and successfully destroys the same 27 items on teardown.
