title: How to have Client uploads go directly to S3 rather than proxying through Django
body: <p>I use a Django and boto3 sdk</p>
  
  <p>This is the current treatment methods.</p>
  
  <p><strong>1. The client sends the file to Django(EC2) <br>
  2. Save the file to Django(EC2) <br>
  3. Send a file stored on Django(EC2) to S3.</strong></p>
  
  <p>However, This is inefficient. So, I would like to do this</p>
  
  <p><strong>1. The client sends the file to Django(EC2) <br>
  2. The real-time transmission in the receiving file S3</strong></p>
  
  <p>I want not to store the EC2.... However, To transfer files to S3 , I need to check the file information in the previous EC2. I do not want to transfer files to S3 from the client.</p>
  
  <p>It is to dynamically transferred to S3 in EC2. </p>
  
  <p>How can I do this?</p>
