title: Does scalability depend on programming language?
body: <p>I have recently come across <code>SCALA</code> while going through the designs of twitter and linkedin. A part of the twitter and linkedin are being shifted to scala for scalability which where originally developed in RoR?</p>
  
  <p>Does changing the programming language guarantee scalability? How exactly is this decided? Can there by any pre-planning on how to scale while designing the system?</p>
  
  <p>Can anyone please give me some insights on this ?</p>
  
  <p>Cheers.</p>
