Public Service Management

You need to identify the public IT services and resources required by each business unit, such as the NTP server, Scalable File Service (SFS), self-built DNS servers, OBS buckets, VM images, certificates, and PaaS services such as CodeArts. Then, you can centrally deploy and maintain these public IT services and share them with all business units in the company. Huawei Cloud provides three resource sharing methods.

  • Network-based sharing: You can use Enterprise Router or VPC Peering to connect networks between accounts and share resources. This method applies only to resources that have IP addresses visible to tenants, such as NTP servers, self-built DNS servers, and SFS.
  • RAM-based sharing: You can use Resource Access Manager (RAM) to configure resource sharing and authorize other organizational units (OUs) and accounts to use the shared resources. This sharing method is more secure. For details about the resources that can be shared across accounts through RAM, see Sharable Cloud Services and Resource Types
  • Sharing based on resource policies: You can use resource policies to grant other accounts permissions to access resources, such as OBS bucket policies, Image Management Service (IMS) image sharing, and Cloud Backup and Recovery (CBR) backup sharing.
