title: AWS - EC2: Why would I need more than one instance?
body: <p>Sorry if there is an obvious answer to this, but I'm currently in the process of setting up a new company, from where I'll be hosting client websites.  Rather than use an external hosting company, I'd like to take full control of this through EC2.</p>
  
  <p>Can multiple websites be hosted on a single instance, or will each new site require it's own instance?</p>
  
  <p>Many thanks,
  L</p>
