Alibaba Cloud DNS:Service linked role for Alibaba Cloud DNS

Last Updated:Aug 14, 2020


The service linked role AliyunServiceRoleForDNS is a Resource Access Management (RAM) role that only Alibaba Cloud Domain Name System (DNS) can assume to access other Alibaba Cloud services. This topic describes the scenarios that the service linked role is applicable to and how to delete the role.

Background information

Alibaba Cloud DNS may need to access other Alibaba Cloud services to implement a specific feature. To meet this requirement, Alibaba Cloud provides the AliyunServiceRoleForDNS role that allows Alibaba Cloud DNS to access other Alibaba Cloud services. For more information about service linked roles, see Service linked roles.


When you use the DNS Monitoring feature, Alibaba Cloud DNS assumes the AliyunServiceRoleForDNS role to access your CloudMonitor resources. You do not need to manually create the service linked role. If the role does not exist, Alibaba Cloud DNS automatically creates the role when you use the DNS Monitoring feature.

Role description

  • Role name: AliyunServiceRoleForDNS
  • Policy name: AliyunServiceRolePolicyForDNS
