title: What is the best approach to design AWS lambda function for CRUD operation
body: <p>For a CRUD application what would be the best approach to design AWS lambda function:</p>
  <ol>
  <li>Create a single lambda function and differentiate each call with a switch case in the handler.</li>
  <li>Create a single lambda function but with a separate handler for each call. Is it possible even?</li>
  <li>Create a separate lambda function for each operation.</li>
  </ol>
  <p>As these are just simple CRUD operations, size is not a big factor. But I am bit concerns with the managing and cost-effectiveness.</p>
