開通靈駿串連後，使用者可通過靈駿串連訪問阿里雲其他雲產品（例如，訪問VPC、建立專線、建立彈性網卡等），進行此類操作時需通過服務關聯角色擷取對應雲產品的存取權限。本文為您介紹靈駿串連執行個體關聯角色（AliyunServiceRoleForEfloVcc）的應用情境以及如何刪除服務關聯角色。
背景資訊
靈駿串連服務關聯角色（AliyunServiceRoleForEfloVcc）是在某些情況下，為了完成靈駿串連自身的某個功能，需要擷取其他雲端服務的存取權限，而提供的RAM角色。更多關於服務關聯角色的資訊請參見服務關聯角色。

建立服務關聯角色
當您第一次建立叢集，進行網路設定，您需要單擊授權服務角色建立按鈕，一鍵建立服務關聯角色（AliyunServiceRoleForEfloVcc）。
刪除服務關聯角色
如果您需要刪除AliyunServiceRoleForEfloVcc（服務關聯角色），需要先釋放依賴這個服務關聯角色的靈駿串連。
釋放靈駿串連可等雲端服務執行個體到期自動釋放。
刪除服務關聯角色具體操作請參見刪除服務關聯角色。
