Everyone loves automated processes. With BizTalk 2013 if you want to provide a repeatable install; you need automation. PowerShell is where it’s at. Lucky for me, other very skilled people already have written PowerShell scripts providing the capability to create hosts and host instances. Sandro Pereira has written and published a PowerShell script to create your BizTalk host instances based upon the best practice of host separation. However, it’s only written for BizTalk 2010.
