I’ll introduce reference information for restricting AWS ALB access to CloudFront only.
There was a requirement to restrict AWS ALB access to CloudFront only, so I’ve compiled the articles I referenced to achieve this.
Refer to the article ALBへのアクセスをCloudFront経由の通信に限定する - サーバーワークスエンジニアブログ.
Refer to the article CloudFrontからカスタムオリジンまでの通信をHTTPS化する方法を2パターン | DevelopersIO.
That’s all from the Gemba about restricting ALB access to CloudFront only.
