Consequently, IBM's customers do not incur software license charges for their zAAPs, reducing their costs of running Java- and XML-oriented applications.
The first commercial production workload for zAAP began on September 1, 2004, at an undisclosed Midwestern U.S. insurance company performing claims processing.
This deployment is probably a mainframe record for speed of both development and adoption, since IBM only began its zAAP design project in 2003.
[citation needed] Third-party independent software vendors (ISVs) have introduced support for execution of their products on zAAP Specialty Engines by using Java or XML Services toolkit from IBM.
The Ivory Server for Java will also take advantage of the zAAP in addition to supporting zIIP and the Integrated Facility for Linux (IFL).
