IBM Software Group | EGL Simplify Innovation IBM Software Group UI Modernization via EGL RUI Migration to EGL Extra Benefit: move to SOA after migration  Service part:  a generatable part containing code that will be accessed: - from EGL code by way of a local or TCP/IP connection (EGL Service). - from any code by way of an HTTP connection (EGL Web service).  Interface part:  Used to access external services as EGL services or simply to provide separation of concern. At development time…  Focus on the business logic  Implement SOA design elements: services and interfaces  Leverage existing business developers for new SOA development  Ignore deployment targets/technology while coding/testing Deploy EGL services… To any platform ( Java to WAS/Tomcat, COBOL to CICS, i5/OS )  As a Web service (uses SOAP)  As a private service (uses CICS ECI or TCP) Leverage external web services…  EGL Interfaces  represent external web services  are created via import from WSDL  allow the EGL developer to stay within the context of EGL programming Refactor migrated EGL code EGL Program EGL Service Java

IBM Software Group | EGL Simplify Innovation IBM Software Group UI Modernization via EGL RUI Rational Application Transformation Briefing Sheet Customer: Business: Agri-business ISV Location: Orlando Context: Requirements: Support for additional platforms (currently only support IBM i) Can’t find RPG skills Richer User Interfaces Scope of problem:5M LOC of RPG systems Have very large and complex RPG programs Solution:Migrating applications to EGL Largest RPG program migrated: 27,000 lines Building new user interfaces in EGL RUI First application in progress; presenting this at their User Conference in March

IBM Software Group | EGL Simplify Innovation IBM Software Group UI Modernization via EGL RUI Positioning of UI modernization offerings  Use these options when …  HATS transformation –Time is of the essence or –Tactical, low-budget situations –Source code is not available  HATS service wrapping and build new UI –A UI technology other than EGL RUI has been selected to build new UI’s for existing logic or –Source code is not available  Migration of interactive programs to EGL RUI –Need to adopt a long term UI modernization solution or –Want to take advantage of the latest web 2.0 widgets and capabilities or –Need better web performance

IBM Software Group | EGL Simplify Innovation IBM Software Group UI Modernization via EGL RUI Summary Existing RPG or COBOL apps will exist for a long time and need a strategic new UI Screen scraping good for tactical web UI Strategic web solutions needed EGL and EGL RUI Easy transition for RPG/COBOL developers Best Web 2.0 tooling on the market today Automated migration to EGL can give you a competitive advantage Evolve RPG and COBOL assets into Web 2.0 … strategic UI modernization solution UI Enrichment opportunities abound Low risk, Quick ROI Easy transition for RPG and COBOL developers Flexible deployment targets Highly productive and flexible language and environment Migrate at your own rate and pace: interactive programs only, complete applications, or entire systems Next Steps Run a pilot Contact Todd Britton or one of our key partners for more
