title: Comparing the new SQL Azure tiers to old ones
body: <p>Now that Microsoft made the new SQL Azure service tiers available (Basic, Standard, Premium) we are trying to figure out how they map to the existing ones (Web and Business).</p>
  
  <p>Essentially, there are six performance levels in the new tier breakdown: Basic, S1, S2, P1, P2 and P3 (details here: <a href="http://msdn.microsoft.com/library/dn741336.aspx">http://msdn.microsoft.com/library/dn741336.aspx</a>)</p>
  
  <p>Does anyone know how the old database tiers map to those six levels? For instance, is Business  equivalent of an S1? S2?</p>
  
  <p>We need to be able to answer this question in order to figure out what service tiers/levels to migrate our existing databases to.</p>
