title: When to set up a nondefault VPC in AWS?
body: <p>When creating an EC2 instance <em>(or some other kind of stuff)</em> on AWS, there appears a default VPC. </p>
  
  <p>Also, as another option, a VPC can be created beforehand and selected during the EC2 instance creation etc..</p>
  
  <p>So, in which use cases should we <strong>create a new VPC instead of using the default one</strong>?</p>
