2. Mainframe today is all about software
 COBOL ,PL/I, ASM 370
 DB2, IMS/DB, VSAM
 CICS, IMS/DC
 JCL
 Scheduling

3. Common wisdom
 Keep running it
 Maintain it
 Increase functionalities
 Monitor the cost
 Rationalization
 Consolidation
 Strategic plans for rewriting
 Automated translation
 Zuberistan rewriting projects

4. But size matters
 Complexity
 No express lane on time scale
 No prototyping on production

5. Millennial effects
 No single one young and brilliant programmer is interested in
 COBOL
 PL/I
 ASM370
 CICS
 …

6. Mobile business effects
 Driven by your marketing and sales people
 Mobile connections ADD UP to web connections
 2000: one user = 1 device
 2016: one user = 3 to 4 devices

Business Cost
 More connections
 Direct impact on MIPS

7. How to break the circle ?
 Modernize – Available Resources – Within Budget – Keep Production Running

8. Process in a nutshell
 Keep the existing code “as it is” including oddities
 Recompile on .NET
 Manage the risk
 Run the same code in parallel on the same DB
 Monitor results until you build confidence
 Switch DB when ready
 Steady secure process

9. Modernization is INCREMENTAL
 Application runs in.NET
 Use Visual Studio
 No one is forced now to write a line of code in COBOL or PL/I
 C# calls or (is called) COBOL, PL/I, ASM370
 Positive evolution of the existing code

10. Technology
 21st century compiler for ASM370, PL/I & COBOL .NET native
 Oddities managed (CICS, DB2, IMS/DB, IMS/DC, VSAM, JCL…)
 Developed in Brussels, Belgium
 A team of 40 engineers & PhD from 16 nationalities
 Selling worldwide
 2 Microsoft Technology Awards (2014, 2016)
 www.raincode.com

11. Next logical steps
 Deep dive in your existing environment & Raincode technology
 Identify quick wins to save MIPS
 Code review for critical processes
 Make a plan and fix deadlines to modernize your applications
They did it because they didn’t know it was impossible.
