本文為您介紹5G高速上云服務CC5G（5G Cloud Connector）的服務關聯角色（AliyunServiceRoleForCCIoT）以及如何刪除5G高速上云服務的服務關聯角色。

背景信息

服務關聯角色是指與某個云服務關聯的RAM角色。在某些場景下，為了完成云服務的某個功能，需要獲取其他云服務的訪問權限。通過服務關聯角色，您可以更好地創建云服務正常操作所需的權限，避免誤操作帶來的風險。更多信息，請參見服務關聯角色。

創建服務關聯角色

創建CC5G時，如果服務關聯角色不存在，系統會自動創建一個名稱為AliyunServiceRoleForCCIoT的服務關聯角色，并且為該角色添加名稱為AliyunServiceRolePolicyForCCIoT的權限策略，授予CC5G訪問其他云資源的權限，策略內容如下。

刪除服務關聯角色

如果您要刪除CC5G服務關聯角色（AliyunServiceRoleForCCIoT），請先刪除CC實例。具體操作，請參見：

1. 刪除云連接器

2. 刪除服務關聯角色

常見問題

為什么我的RAM用戶無法自動創建CC5G服務關聯角色（AliyunServiceRoleForCCIoT）？

您需要擁有指定的權限策略，才能自動創建或刪除CC5G服務關聯角色（AliyunServiceRoleForCCIoT）。因此，在RAM用戶無法自動創建CC服務關聯角色（AliyunServiceRoleForCCIoT）時，您需為其添加以下權限策略。

{
    "Statement":[
        {
            "Action":"ram:CreateServiceLinkedRole",
            "Resource":"*",
            "Effect":"Allow",
            "Condition":{
                "StringEquals":{
                    "ram:ServiceName":"cciot.aliyuncs.com"
                }
            }
        }
    ],
    "Version":"1"
}
