title: How to create or see existing App Service Plans in Azure portal and modify them?
body: <p>I am trying to determine <code>Azure portal</code> provides any option to create an <code>App Service Plan</code> in a separate step (not while creating the website) and to modify them.
  Currently I am creating <code>App Service Plans</code> in the WebSite creation step and modify them in WebSite's <code>Scale</code> option.</p>
  
  <ol>
  <li>Is there any way to create them separately and see a list of available
  <code>App Service Plans</code>?</li>
  <li>Do websites created within an <code>App Service Plan</code> share the resources in it (CPU, Memory etc)?</li>
  <li><p>What exactly happens when there is an auto scale up?</p>
  
  <p>a.) Will it create a new instance of the <code>App Service Plan</code> and replicate all the websites within it?</p>
  
  <p>b.) or will it create a new instance of the website and share the resources of same <code>App Service Plan</code>?</p></li>
  </ol>
  
  <p>I am confused because, the App Service Settings (pricing tiers, scale-up option etc) are seen in websites scale option.</p>
  
  <p>Please clarify my doubts.</p>
  
  <p>Thanks in advance.</p>
