IAM Roles and Permissions
Updated over 7 months ago

Druva CloudRanger requires an Identity Access Management (IAM) role to access and manage your AWS workloads. To configure your Druva CloudRanger account, you will need to grant CloudRanger third-party access to your AWS account.

To create an IAM role, Druva CloudRanger provides a CloudFormation template that provisions the CloudFormation stack within your AWS environment. This then generates the following IAM permissions for Druva CloudRanger to access your AWS Account:

  • IAM Role

  • IAM Instance Profile

  • IAM Policy

The generated Amazon Resource Name (ARN) of the IAM role is then linked back to CloudRanger so that it can run backup and restore jobs on your AWS workloads.
