title: Tridion DTAP Clarified - How many Content Delivery setups do I need?
body: <p>I asked about developer setup for Tridion DTAP (development, test, acceptance, and production) <a href="https://stackoverflow.com/questions/11166754/proper-dtap-setup-for-content-delivery">in this other question</a>, but understand the example didn't match a typical DTAP scenario.</p>
  
  <p>Chris Summers explains the CM-side well in his <a href="http://www.urbancherry.net/blogengine/post/2010/02/06/The-Fifth-Environment.aspx" rel="nofollow noreferrer">Fifth Tridion Environment post</a>. But for clarity, could I get help understanding the ideal setup?</p>
  
  <h2>CMS environments</h2>
  
  <ul>
  <li>D = Development</li>
  <li>T = Test</li>
  <li>A = Acceptance</li>
  <li>P = Production</li>
  </ul>
  
  <p>I understand typical authors only use Production and publish from CMS Production to "Live" and "Staging." The other environments are for development.</p>
  
  <h2>CD?</h2>
  
  <p><strong>Does "Live and Staging" apply to each of the other environments--does that mean 8 content delivery setups (per website)?</strong></p>
  
  <p>And if so, where is it okay to consolidate--fewer CMS environments? Fewer target types?</p>
