IT-Symposium 2008 04.06.2008 Drivers for change New Customers Reduce Increase Agility Costs A Accuracy c Increase Your c e Business D s a s t i On a b i l i VAX / Alpha t y s s I e s l l l g T a i k e n a c d S t r h s o n o o h f l o S Cost of g y Support Understanding your business requirements • Business challenges of legacy applications – Business fit today – Business fit tomorrow – Do they provide competitive advantage – Batch processing rather than straight-through business – Speed of response to changing requirements – Cost of ownership www.hp-user-society.de 3
IT-Symposium 2008 04.06.2008 Understanding your business requirements • Does your application fit in with your IT strategy? – Platform issues (support, extensibility, upgrades, cost, etc) – Service Oriented Architecture (SOA) – Integration issues – Modern tools not always available – Skills difficult to obtain Transition options – the business choice Migrate Do Nothing Modernize Upgrade Re-write Package www.hp-user-society.de 4
IT-Symposium 2008 04.06.2008 Modernize transition option To modernize can be the right option when: • Application generally meets business requirements Do Nothing Migrate • Application can be made to meet your IT strategy Modernize • Application can be made to integrate with other Upgrade applications through SOA Package Re-write • You have the right skills match Considerations: • Sufficient analysis to ensure the cost model is right • Tight project management and control scope • Do not underestimate the testing • Can give best results for spend if controlled Migrate transition option To migrate can be the right option when: Migrate • The application meets the business requirement Do Nothing • The platform does not meet your IT strategy Modernise • Integration is important Upgrade • Cost of ownership needs to be lowered Package Re-write Considerations: • Firm cost and timescale for project • It will be fundamentally the same application without re-engineering • But there can be GUI and RDBMS improvements • Migration involves the least testing • No user re-training • Then use the latest tools for SOA to modernize the application www.hp-user-society.de 5
IT-Symposium 2008 04.06.2008 Modernization Modernization • Greater agility • Easier integration • Integration with new technologies .NET and J2EE • Leads naturally to a Service Oriented Architecture (SOA) • Before ….. and/or after migration • But how can SOA be achieved while remaining on the VAX / Alpha platform? www.hp-user-society.de 6
IT-Symposium 2008 04.06.2008 Gartner “The introduction of Web services is accelerating the spread of SOA into mainstream projects. SOA is attractive because it enables reuse of logic and data in multiple contexts delivering composite applications.” Transoft Component Adapters • SOA “middleware” architecture Enable integration of legacy systems into – Distributed GUI applications – Web enabled applications & e-Business • Optimum reuse of existing application logic as Services Capitalize on business rules and logic in existing legacy applications – Fortran, Pascal, COBOL, C, BASIC, Other • Allows new functionality to be added incrementally and quickly www.hp-user-society.de 7
