terraform-aws-multi-az-subnets ![Latest Release](https://github.com/cloudposse/terraform-aws-multi-az-subnets/releases/latest) ![Slack Community](https://slack.cloudposse.com) [![README Header][readme_header_img]][readme_header_link] [![Cloud Posse][logo]](https://cpco.io/homepage) Terraform module for multi-AZ subnets provisioning. The module creates private and public subnets in the provided Availability Zones. The public subnets are routed to the Internet Gateway specified by var.igw_id. nat_gateway_enabled flag controls the creation of NAT Gateways in the public subnets. The private subnets are routed to the NAT Gateways provided in the var.az_ngw_ids map. If you are creating subnets inside a VPC, consider using cloudposse/terraform-aws-dynamic-subnets instead. --- This project is part
