# Onboard an AWS account with Terraform

This section describes how to use the Zesty AWS account Terraform module to connect AWS accounts to Zesty and enable Commitment Manager, Zesty Compute Optimization (“Compute Optimization”), or base read-only access.

The module creates and manages the AWS account resources required by Zesty, including:

- an IAM role that Zesty can assume
- an IAM policy with the permissions required by the selected products
- an external ID for secure role assumption
- a Cost and Usage Report (CUR) and S3 bucket when required, or access to an existing CUR
- Athena and Glue resources when Compute Optimization is enabled on a management account
- Zesty account registration
- Helm values for Compute Optimization cluster installation when Compute Optimization is enabled

Use one module block for each AWS account. When multiple Zesty products are enabled in the same AWS account, they share the same IAM role, IAM policy, and Zesty account registration.
