Managed instance role
The managed instance role is the IAM role that SSM Agent assumes on each
Azure virtual machine after it's installed and registered. The role grants the
agent the permissions it needs to call the Systems Manager service from the VM. Unlike
the other three roles, this is not created on your behalf. You select an
existing role during the connector setup wizard, or let the wizard create the
recommended role AmazonEC2RunCommandRoleForManagedInstances with
the AmazonSSMManagedInstanceCore AWS managed policy
attached.
For information about creating this role and the policies you can attach to it, see Create the IAM service role required for Systems Manager in hybrid and multicloud environments. Cloud Connector activations use the same role pattern as hybrid activations.
