I’ll introduce reference information for restricting AWS ALB access to CloudFront only.

Background: Want to Restrict ALB Access

There was a requirement to restrict AWS ALB access to CloudFront only, so I’ve compiled the articles I referenced to achieve this.

Restricting Access to CloudFront → ALB Only

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.

Pattern for HTTPS Communication from CloudFront → ALB

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.
