title: Google App Engine vs Tomcat
body: <p>I was able to create the basic 'hello world' program.</p>
  
  <p>When I tried to understand the difference between a cloud and a server I learned that Cloud is where you have an access to virtual instance created exclusively for you and you are free to choose and install software of your choice.Why Google App Engine(GAE) is used widely where as tomcat is not used. What are major differences between GAE and Tomcat?</p>
