# Create the required Google Cloud resources

Assemble Google Cloud subscription, configure roles for auto-scaling, and identify a resource group to deploy access nodes.

Prerequisites

You must have permissions to create IAM roles, service accounts, and compute resources in your Google Cloud project.

## Procedure

1. Identify the Google Cloud project where the access nodes will be dynamically deployed.

2. Create a custom IAM role (for example, CommvaultGCPAutoScale) that includes permissions to:

   - Create and delete compute instances

   - Manage disks and networking

   - View and use images

   - Write logs

3. Create a service account to serve as Scale Manager, and assign the custom role to it.

4. Identify the project where the access nodes will be deployed.

5. For each region, identify the following resources that will be used by deployed access nodes:

   - VPC network

   - Subnet

   - Cloud Storage bucket

6. (Optional) Configure an external IP access for compute instances if required by your network design.
