This is an opinionated Terraform Module for provisioning a VPC on AWS. It makes use of the community provided (extensive) module to provision a VPC on AWS.
In particular, it does the following:
- Provisions (optional) public, private, database, intra and redshift subnets
- One NAT gateway per AZ
- Removes all default security group and ACL rules
- Provides sane ACL rules for network access
