Abstract
WebSphere Application Server is a cross-platform family. It runs on small laptops all the way up to the largest mainframe computer. And across that entire spectrum the open standard support is fully aligned. That is, "WebSphere is WebSphere" at that specification line and above.But does that mean WebSphere Application Server is unaware of the platform it runs on? Not at all. WebSphere Application Server for z/OS in fact exploits the System z and z/OS platform to a considerable degree.So to the question "Why WebSphere Application Server on z/OS," the answer really does boil down to "Because of System z and z/OS." The value attributes of the platform and the way WAS z/OS exploits them is what make WebSphere Application Server for z/OS unique and powerful.
