前置き

ボタン一つでEC2とRDSの起動や停止をしたいとユーザーからリクエストがありました。
ユーザーの端末にAWS CLIをインストールし、バッチファイルで実行してもらうことにしました。
アクセスキーの払い出しは推奨されませんが、今回はユーザー要件を考慮し、
IAMポリシーを必要最低限に絞ることでセキュリティリスクを軽減しています。

前提条件

AWS CLIがインストール済み
AWS CLIの認証情報が設定済み（aws configure実行済み）
Windows環境（バッチファイル実行可能）
対象のEC2・RDSリソースへのアクセス権限

IAMポリシー

EC2インスタンスが暗号化されたEBSボリュームを使用している場合、
KMS権限を忘れがち。
