title: Two types of Azure Portal and ASM vs ARM - What is the picture behind the curtains?
body: <p>I often get confused when people suggest me to go to older azure portal and sometimes to newer azure portal.</p>
  
  <p>old portal- <a href="https://manage.windowsazure.com" rel="noreferrer">https://manage.windowsazure.com</a></p>
  
  <p>New Portal- <a href="https://portal.azure.com" rel="noreferrer">https://portal.azure.com</a></p>
  
  <p>The UI as completely different. Even some features are available in old which are not available in New and vice versa. I really get confused when to use which one.</p>
  
  <p>Is there any documentation or help from where I can refer when to use which one. Also I would like to understand why there are two portals. I mean the second one can be released once whole development task is completed for that.</p>
  
  <p>Also, it is being said MS will be deprecating ASM and ARM will be the one coming in picture. Resource group will replace cloud service approach. This is confusing. Do we require change from Infrastructure perspective(as an admin) by us.
  The cmdlets we use in ASM will work the same or MS will come up with something new approach or some new PS or something else? It totally confuses me.</p>
