This practice is known as Continuous Integration; for every change submitted to an application — even to development branches — it’s built and tested automatically and continuously, ensuring the introduced changes pass all tests, guidelines, and code compliance standards you established for your app.

AWS Policy allows to restrict the permissions to an S3 resource(s) using pattern. The most often requirement is to restrict a specific users to list hierarchy of folder(s) and read/write/delete actions to certain folders.
