The document discusses challenges related to integrating mainframe applications. It notes that customer applications may span mainframe, PC, Unix and other environments. The complexity of existing application portfolios is also highlighted, with a sample application diagram showing dependencies across multiple systems. Simplifying such complex application landscapes and enabling integration between new and legacy platforms is presented as an opportunity that service providers can address.
