title: Frontend-backend communication for a mobile app
body: <p>I am pretty new to stuff related to server and backend services and I want to develop a mobile app with a backend part. I want this backend to serve an ios app, an android app as well as a website.
  My concerns today are how does the frontend part communicate with the backend part :</p>
  
  <ul>
  <li>does it work the same way a website works ? (Http request to the server ?)</li>
  <li>how does happen the exchange of datas between the frontend and the backend ?</li>
  <li>which are the common solutions to my problem ?</li>
  <li>is there an efficient way to desing this backend to serve mobile apps as well as a website ?</li>
  <li>is parse (<a href="https://parse.com/" rel="noreferrer">https://parse.com/</a>) a good starting point ?</li>
  </ul>
  
  <p>Thanks</p>
