title: SAP PI/PO vs open source ESB advantages
body: <p>Is SAP PI/PO now considered a true ESB? I've read various sources claiming it was not quite there 4-5 years ago.</p>
  
  <p>And what if you have a very SAP-centric environment, would it be very strongly suggested to use PI/PO instead of the more standard integration platforms such as Mule ESB, Jboss Fuse, BizTalk and Oracle ESB?</p>
  
  <p>If you primarily have expertise with the platform agnostic ESB's mentioned, would it still be worth integrating with SAP Pi? What are the advantages of PI?</p>
  
  <p>I see they all have some option to integrate with SAP, but unbiased information seems hard to come by in the SAP-scene.</p>
