IBM Software Group | Web. Sphere software The Business Benefit of Application Reuse ? “Industry has already invested trillions in IT. If faster results can be achieved reusing rather than rewriting, only a fool would chose to rewrite” 24% Faster ROI using SOA! 24% Faster! -- John Balderson, The Spencer Group Non-SOA Components http: //www. logiclibrary. com/pdf/wp/ROI_of_SOA. pdf What is the cost to your IT budget if you are not already reusing your applications? 3

IBM CICS application architecture – a framework for reuse CICS Transaction Server Transaction Client 3270 Presentation P Integration logic Business logic Data access I B D Best practice in CICS application design is to separate key elements of the application, in particular: - Presentation logic eg. 3270, HTML, XML - Integration or aggregation logic Menu, router, tooling - Business logic Reusable component - Data access logic VSAM, DB 2, IMS, … Provides a framework for reuse and facilitates separation of concerns, clear interfaces, ownership, and optimisation 6 © Copyright IBM Corporation 2009

Operational Dashboards - UK bank Business events such as major financial transactions, exceptions, threshold breaches etc. are often difficult to expose from operational systems in real-time. Real-time event alerting can be useful for fraud detection, compliance monitoring, business intelligence and account management. IT events from operational applications, infrastructure components and systems management often provide indicators of business issues. Changing situations demand flexible dashboards with the ability to drill down and analyse any element of business or IT performance Mashup Hub Manager Operations 44 Catalogue Mashup Systems Mgmt.
