title: How can I access a low-level client from a Boto 3 resource instance?
body: <p>For example, I have this code:</p>
  
  <pre><code>import boto3
  
  ec2 = boto3.resource('ec2')
  
  # Where is the client???
  </code></pre>
  
  <p>Do I need to call <code>boto3.client('ec2')</code> or is there another way?</p>
