title: Append data to an S3 object
body: <p>Let's say that I have a machine that I want to be able to write to a certain log file stored on an S3 bucket.</p>
  
  <p>So, the machine needs to have writing abilities to that bucket, but, I don't want it to have the ability to overwrite or delete any files in that bucket (including the one I want it to write to). </p>
  
  <p>So basically, I want my machine to be able to only append data to that log file, without overriding it or downloading it.</p>
  
  <p>Is there a way to configure my S3 to work like that? Maybe there's some IAM policy I can attach to it so it will work like I want?</p>
