title: Differences between Azure App Services and Cloud Services
body: <p>I've started learning about Microsoft Azure last year and one of the services provided was the Cloud Services. The way I understand Cloud Services is that it is a service meant to allow one to build N-tier apps. So it is possible to set, for instance, a Web Role hosting one ASP.NET Web API project and some Worker Roles for background processing and so on. There was also the Web Sites service.</p>
  
  <p>Now at Build 2015 it was presented Azure App Services which basically is made of </p>
  
  <ul>
  <li>Web Apps</li>
  <li>API Apps</li>
  <li>Logic Apps</li>
  <li>Mobile Apps</li>
  </ul>
  
  <p>Now I don't get when one should use Cloud Services and when one should use App Services. I mean, I got the impression that Web Apps together with API Apps and Logic Apps is the same as Cloud Services, but I'm not sure.</p>
  
  <p>So, what is the difference between Cloud Services and App Services and when one should be chosen instead of the other?</p>
