title: Automatically run new instance of my web application when user buy new license
body: <p>My question is how can I run a new instance of my java web application every time someone buy a new license or when someone wants to try on the application. What technologies are involved in this kind of functionality. </p>
  
  <p>For example, the links bellow user can try the software and even make your domain to activate his instance of the software. The interesting thing is that every new version of the product all customers are automatically update.</p>
