Detecting Changes in GitHub Repository Using AWS Services

Hi,

the simplest way I can think of is to set up a Github webook which will invoke an AWS Lambda from which you can do whatever you want on AWS Cloud.

See doc for webhooks: https://docs.github.com/en/webhooks/about-webhooks

Webhooks provide a way for notifications to be delivered to an external web server 
whenever certain events occur on GitHub.

You have a full sample here: https://github.com/chuyskywalker/aws-lambda-github-webhook

You can directly invoke Lambda via its inocation URL: https://aws.amazon.com/blogs/aws/announcing-aws-lambda-function-urls-built-in-https-endpoints-for-single-function-microservices/

Best,

Didier
