title: Azure data storage encryption?
body: <p>I am creating an azure based application that must be pci compliant. There is an understanding within my company that to meet this compliancy any personally identifiable information (PII) should be stored encrypted.</p>
  
  <p>I have a number of questions.</p>
  
  <p>Is it true that pci compliance means encrypting PII within the data store?</p>
  
  <p>What are my options with this on Azure?</p>
  
  <p>I would like to be storing data in documentdb as this would be the closest match to the format of the data within the application. Most of the data is document based and json. Would this meet the PCI compliance standards?</p>
  
  <p>Does it make a difference if the data store that contains payment and card info is different to that containing the PII?</p>
