1. Size matters Mainframes run the world. Alex Huart alex@raincode.com Chief Evangelist Officer Cologne, June 2016 10 largest insurance companies run on zSystems Millions of Instructions Per Second http://www-03.ibm.com/systems/z/

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 0 200 400 600 800 1000 1200 1400 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.
