title: Is it possible to restrict access to some folders in a single aws s3 bucket to different users?
body: <p>I am building an application to allow users to organize their files/folders.</p>
  <p>I am using an AWS S3 bucket under the hood to store the files.</p>
  <p>I read that it wasn't a good practice to have a bucket per user architecture since it is not designed for that purpose but I am not comfortable having to check myself that no one access to others files.</p>
  <p>Is there a way to restrict some folders (and their subcontent) to some users inside a bucket ?</p>
