Drivers for change 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

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

Modernize Re-write Package Upgrade Migrate Do Nothing Transition options – the business choice

Modernize Re-write Package Upgrade Migrate Do Nothing

Modernize transition option 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

To modernize can be the right option when:

  • Application generally meets business requirements
  • Application can be made to meet your IT strategy
  • Application can be made to integrate with other

applications through SOA

  • You have the right skills match

Migrate Modernise Re-write Package Upgrade Do Nothing

Migrate transition option 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

To migrate can be the right option when:

  • The application meets the business requirement
  • The platform does not meet your IT strategy
  • Integration is important
  • Cost of ownership needs to be lowered

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?

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

Case Study Balfour Beatty Utility Solutions Limited (BBUSL)

  • “Design Programs” VMS Migration to Windows

Background

  • BBUSL “Design Programs” used to analyse and design overhead

power transmission lines and tower structures

  • In 1966, early programs originally written in Algol for ICL mainframe

environment

  • In 1981, acquired Algol to Fortran translator (written in Fortran) on

DEC VAX with VMS – Design Programs translated to Fortran

  • Further modules written in Fortran
  • Integrated with first generation CAD package (“DOGS”)
  • In 2005, on DEC VAX and VMS 5.5-2

IT-Symposium 2008 04.06.2008 www.hp-user-society.de 18

slide-19
SLIDE 19

Background continued

  • In 2005, concluded:

– Ageing hardware unreliable – Expensive to maintain – Slow to operate – No scope for modern enhancements like Graphical User Interface (GUI) – Difficulty in accessing programs remotely – DOGS CAD package was not up to modern standards

  • In summary, this situation was a risk to the business

The Options

Design Programs – unique application, provide competitive advantage

  • No equivalent proprietary packages available
  • Re-host on modern Alpha or Itanium

– Expensive to purchase and maintain – Remain reliant on limited and reducing VMS skills – Merely postpone the inevitable

  • Migrate to Windows

– Preferred in-house platform – In-house skills – Integrate with modern CAD package

The Migration Process

  • Met Transoft at VMS seminar

– Discussed options

  • Completed OpenVMS Migration Questionnaire
  • Transoft commenced PathFinder Assessment Project - 3 weeks
  • Conclusions:

– Migrate to Windows with Intel Fortran – Transoft Open Libr8 to support VMS System Services – Transoft Open DCL emulator – Offered fixed price migration project

The Migration Process

  • Transoft contracted for Migration Project

– Algol translator (in Fortran) migrated first

  • Tested by ensuring Algol code translated as before

– Migrated the translated Fortran

  • Complexity - ‘ICL’ file system
  • Completed in 8 months
  • Subsequently replaced DOGS CAD package with DRAWTRAD

developed exclusively for BBUSL.

  • If modernization of systems on your OpenVMS platform via SOA is

the option for you – Establish your modernization needs – Instigate an initial pilot project – Provide further enhancements through iterative projects

  • If migration is the option for you

– Action a PathFinder Assessment Project – Then migrate

  • Either Transoft undertakes fixed-price migration
  • Or use Transoft migration tools to do your own migration with

training & mentoring

  • Or a combination

– Post-migration, positioned for modernization via SOA

In summary - the way forward
