Create the required AWS resources

Creating a scaling configuration for AWS requires careful preparation and configuration of certain resources. This includes identifying an AWS account, creating necessary custom IAM roles, gathering required infrastructure and hardware details, and associating a server group with the AWS scaling profile client.

Procedure

1. Determine the AWS account where the access nodes will be dynamically deployed.

2. Set up an access node for the Amazon Scale Manager node and associate the required STS assume role policy.

3. Create the following custom roles to define permissions required for auto-scaling:

   • CommvaultScaleManagementRole
   • CommvaultComputeRole

   Ensure the user performing this configuration has IAM permissions to:

   • Create IAM roles
   • Attach policies to roles
   • Pass roles (if used by services such as EC2, Lambda, etc.)
   • Create or update a CloudFormation stack

4. Identify the resource group and AWS region where the access nodes will be deployed.

5. Determine the infrastructure and hardware configuration for the EC2 instance:

   • EC2 key pair
   • VPC ID
   • Subnet ID

6. Identify or create the server group to which the AWS scaling profile client will be associated.
