Using service-linked roles for AWS IoT FleetWise

AWS IoT FleetWise uses AWS Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to AWS IoT FleetWise. Service-linked roles are predefined by AWS IoT FleetWise and include the permissions that AWS IoT FleetWise needs to send metrics to Amazon CloudWatch. For more information, see Monitor AWS IoT FleetWise with Amazon CloudWatch.

A service-linked role makes setting up AWS IoT FleetWise quicker because you don’t have to manually add the necessary permissions. AWS IoT FleetWise defines the permissions of its service-linked roles, and unless defined otherwise, only AWS IoT FleetWise can assume its roles. The defined permissions include the trust policy and the permissions policy. This permissions policy can't be attached to any other IAM entity.

You can delete a service-linked role only after first deleting their related resources. This protects your AWS IoT FleetWise resources because you can't inadvertently remove permission to access the resources.

For information about other services that support service-linked roles, see AWS services that work with IAM, and look for the services that have Yes in the Service-linked roles column. To view the service-linked role documentation for that service, choose a Yes with a link.
