# Deploy Vault to AWS
|
||||
|
||||
This folder contains a Terraform module for deploying Vault to AWS
|
||||
(within a VPC). It can be used as-is or can be modified to work in your
|
||||
scenario, but should serve as a strong starting point for deploying Vault.
|
||||
|
||||
See `variables.tf` for a full reference to the parameters that this module
|
||||
takes and their descriptions.
