Real Life Legacy Modernization

Reasons Why Organizations Choose to Modernize ¬ Protects Existing Investments ¬ Quickly Improves Business Efficiency ¬ Increases Application Reach ¬ Reduces Maintenance Burden

SOA starts with Legacy Modernization GOVERNANCE Monitoring and optimization Processes and Web 2. 0 applications via Composition Business services via Orchestration Reusable services via Legacy Modernization Monolithic applications

Crossvision Legacy Modernization 5 Solutions for a modular step-by-step approach

Web Enablement What does it do? Simplifies the usage and extends the reach of legacy systems Benefits: ¬ Increase productivity of end users ¬ Reduce training times and costs ¬ Improve service to customers and business partners ¬ New end-user experience with Web 2. 0 and AJAX Modernized 1800 green screens in 3 months

SOA Enablement What does it do? Enables reuse of legacy functionality to Web services for SOA environments Benefits: ¬ Reuse existing functionality ¬ Automate business processes (BPM) ¬ Standard-based Integration ¬ Ready for SOA governance Underwriting process is now received, processed and approved within a day instead of 18 days

Application and Data Integration What does it do? Merging and integrate data or functionality Benefits: ¬ High performance and availability ¬ Covers multiple types of integration ¬ Improve SAP business processes ¬ More current data for reporting and data warehouse environments Integration of existing host applications (Cobol, CICS, Natural) with SAP Net.

Increase User Productivity with Composite Applications STUDENT HOME VIEW The Home Page of the Crossvision Campus Connect shows real time data from different sources in one single composite and contextual view.

Increase User Productivity with Composite Applications ADD A COURSE Adding a Course gives you a view that shows your current classes and an area where you can browse courses and view in real time if there is an opening in the course and more detailed information before applying for it. Class status of being open or closed will update in realtime.

Increase User Productivity with Composite Applications ADMIN REPORTS This is an example of how powerful in Context applications are in this report. An Administrator will be able filter the Data, drill in even more and act on it to make a more informed decision.

Customer Best Practices ¬ Extend and Reuse Legacy Applications and Business Functions as Fine Grained or Business Services ¬ Implement an Enterprise Service Bus (ESB) as the ‘back bone’ of your SOA, to allow services to be loosely coupled and allow for the creation of composite services ¬ Implement a SOA Governance and Management Tool, to allow for management, impact analysis and life-cycle management in the new Architecture ¬ Implement a robust security layer to protect web services, even if they are only deployed internally ¬ Implement Best Practices and Methodologies to ensure reuse of services and to support Business and IT resources
