Serverless App Engine (SAE) は、他の Alibaba Cloud リソースにアクセスするためにサービスリンクロール（SLR）を使用します。本トピックでは、SLR のユースケースおよびその作成・削除方法について説明します。
SLR とは
一部のシナリオでは、SAE が他のクラウドサービスにアクセスする必要があり、これにより完全な機能が提供されます。たとえば、アプリケーションを作成する際、SAE はご利用の Virtual Private Cloud (VPC) など、ご利用のリソースに関する情報を取得する必要があります。SLR は、SAE が VPC のようなサービスにアクセスするために必要な権限を付与します。この方法により、必要な最小限の権限のみを安全にデリゲートできるため、運用ミスのリスクを低減できます。SLR の権限ポリシーは事前定義されており、リンクされたサービスによって管理されています。このポリシーを変更または削除したり、ロールに追加のポリシーをアタッチまたはデタッチしたりすることはできません。詳細については、「サービスリンクロール」をご参照ください。

}SLR の作成
SAE は SLR を自動的に作成できます。SLR がまだ作成されていない場合、SAE コンソールにログインすると、Serverless App Engine (SAE) へようこそ ダイアログボックスが表示されます。[確認] をクリックして、SLR を作成します。
ダイアログボックスには、新しく作成されるロールの名前が AliyunServiceRoleForSAE であり、AliyunServiceRolePolicyForSAE ポリシーを使用することが記載されています。このロールにより、SAE は VPC、RDS、ECS、SLB、Container Registry (ACR)、Log Service (SLS)、Apsara File Storage (NAS)、Application Real-Time Monitoring Service (ARMS) などのクラウドリソースにアクセスできます。このアクセスは、イメージのプル、モニタリングデータの収集、ログのエクスポート、データの永続化などの操作に必須です。
説明
Serverless App Engine (SAE) へようこそ ダイアログボックスは、SLR を作成するまで、SAE コンソールにログインするたびに表示され続けます。
SLR の削除
SLR を削除する場合は、まず Alibaba Cloud アカウントで SAE 上にデプロイしたすべてのアプリケーションを削除する必要があります。
