title: Azure: Why is it advised to use multiple storage accounts for a virtual machine scale set?
body: <p>In the documentation for <a href="https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-overview" rel="nofollow noreferrer">Virtual Machine Scale Sets</a> it says</p>
  
  <blockquote>
    <p>Spread out the first letters of storage account names as much as possible</p>
  </blockquote>
  
  <p>I have two questions to this:</p>
  
  <ul>
  <li><p>Why should you use multiple Storage Accounts at all?</p></li>
  <li><p>Why is Azure creating 5 Storage Accounts if I create a new Virtual Machine Scale Set through portal?</p></li>
  <li><p>Why should I spread the first letters as much as possible?</p></li>
  </ul>
