This is part of a project that aims to create the infrastructure necessary for Cloud Foundry to be installed. For reasons of modularity, it does not install CF or microbosh itself. You probably don't want to use this repo directly.
This terraform repo will create a VPC in Amazon, two subnets - one as a 'bastion' to put any ssh and nat servers you need, and one for 'microbosh', and the nat server itself.
Deploy Cloud Foundry
This repo doesn't actually deploy Cloud Foundry. See https://github.com/cloudfoundry-community/terraform-aws-cf-install for that.
The various subnets that are created by this repo, as well as by terraform-aws-cf-net.
