    1. Move to Hadoop, Go Faster and Save Millions - Mainframe Legacy Modernization Sunilkumar Kakade – Director IT Aashish Chandra – DVP, Legacy Modernization Hadoop Summit 2013- June 26th, 2013

    2. Legacy Rides The Elephant Hadoop is disrupting the enterprise IT processing.

    3. Recognition - Contributors • Our Leaders • Ted Rudman • Aashish Chandra • Team • Simon Thomas • Sunil Kakade • Susan Hsu • Bob Pult • Kim Havens • Murali Nandula • Willa Tao • Arlene Pynadath • Nagamani Banda • Tushar Tanna • Kesavan Srinivasan

    4. The Enterprise Challenge

    5. Mainframe Migration - Overview • In spite of recent advances in computing, many core business processes are batch-oriented running on mainframes. • Annual Mainframe costs are counted in 6+ figure Dollars per year, potentially growing with capacity needs. In order to tackle the cost challenge, many organization have considered or attempted multi-year mainframe migration/re-hosting strategies.

    6. Batch Processing Characteristics • Characteristics* • Large amounts of input data are processed and stored (perhaps terabytes or more). • Large numbers of records are accessed, and a large volume of output is produced • Immediate response time is usually not a requirement, however, must complete within a “batch window” • Batch jobs are often designed to run concurrently with online transactions with minimal resource contention. *Ref:. IBM Redbook

    7. Batch Processing Characteristics • Key infrastructure requirements: • Sufficient data storage • Available processor capacity, or cycles • job scheduling • Programming utilities to process basic operations (Sort/Filter/Split/Copy/Unload etc.)

    8. Why Hadoop and Why Now? THE ADVANTAGES: • Cost reduction • Alleviate performance bottlenecks  • ETL too expensive and complex • Mainframe and Data Warehouse processing  Hadoop THE CHALLENGE: • Traditional enterprises lack of awareness THE SOLUTION: • Leverage the growing support system for Hadoop • Make Hadoop the data hub in the Enterprise • Use Hadoop for processing batch and analytic jobs

    9. The Architecture • Enterprise solutions using Hadoop must be an eco-system • Large companies have a complex environment: • Transactional system • Services • EDW and Data marts • Reporting tools and needs • We needed to build an entire solution

    10. MetaScale’ s Hadoop Ecosystem

    11. Hadoop based Ecosystem for Legacy System Modernization MetaScale

    12. Mainframe Batch Processing Architecture

    13. MetaScale Batch Processing Architecture With Hadoop

    14. Typical Batch Processing Units (JCL) on Mainframe

    15. Batch Processing Migration With Hadoop Seamless migration of high MIPS processing jobs with no application alteration

    16. Mainframe to Hadoop-PIG conversion example Mainframe JCL //PZHDC110 EXEC PGM=SORT //SORTIN DD DSN=PZ.THDC100.PLMP.PRC, // DISP=(OLD,DELETE,KEEP) //SORTOUT DD DSN=PZ.THDC110.PLMP.PRC.SRT,LABEL=EXPDT=99000, // DISP=(,CATLG,DELETE), // UNIT=CART, // VOL=(,RETAIN), // RECFM=FB,LRECL=40 //SYSIN DD DSN=KMC.PZ.PARMLIB(PZHDC11A), // DISP=SHR //SYSOUT DD SYSOUT=V //SYSUDUMP DD SYSOUT=D //*__________________________________________________ //* SORT FIELDS=(1,9,CH,A) - 500 Million Records sort took 45 minutes of clock time on A168 mainframe PIG a = LOAD 'data' AS f1:char; b = ORDER a BY f1; - 500 Million Records sort took less than 2 minutes More benchmarking studies in progress

    17. Mainframe to Hadoop-PIG conversion example Mainframe JCL //PZHDC110 EXEC PGM=SORT //SORTIN DD DSN=PZ.THDC100.PLMP.PRC, // DISP=(OLD,DELETE,KEEP) //SORTOUT DD DSN=PZ.THDC110.PLMP.PRC.SRT,LABEL=EXPDT=99000, // DISP=(,CATLG,DELETE), // UNIT=CART, // VOL=(,RETAIN), // RECFM=FB,LRECL=40 //SYSIN DD DSN=KMC.PZ.PARMLIB(PZHDC11A), // DISP=SHR //SYSOUT DD SYSOUT=V //SYSUDUMP DD SYSOUT=D //*__________________________________________________ //* SORT FIELDS=(1,9,CH,A) - 500 Million Records sort took 45 minutes of clock time on A168 mainframe PIG a = LOAD 'data' AS f1:char; b = ORDER a BY f1; - 500 Million Records sort took less than 2 minutes More benchmarking studies in progress

    18. Mainframe Migration – Value Proposition Cost Savings Open Source Platform Simpler & Easier Code Business Agility Business & IT Transformation Modernized Systems IT Efficiencies Optimize Companies can SAVE 60% ~ 80% of their Mainframe Costs with Modernization High TCO Mainframe Optimization: -5% ~ 10% MIPS Reduction -Quick Wins with Low hanging fruits Mainframe Migration Mainframe ONLINE -Tool based Conversion -Convert COBOL & JCL to Java Inert Business Practices Convert Typically 60% ~ 65% of MIPS are used in Mainframes by BATCH processing PiG / Hadoop Rewrites Resource Crunch Mainframe BATCH -ETL Modernization -Move Batch Processing to Hadoop Estimated 45% of FUNCTIONALITY in mainframes is never used

    19. Mainframe Migration – Traditional Approach • Traditional approaches to mainframe elimination call for large initial investments and carry significant risks – It is hard to match Mainframe performance and reliability. • Many organizations still utilize mainframe for batch processing applications. Several solutions presented to move expensive mainframe computing to other distributed proprietary platform, most of them rely on end-to-end migration of applications.

    20. Mainframe Batch Processing MetaScale Architecture • Using Hadoop, Sears/MetaScale developed an innovative alternative that enables batch processing migration to Hadoop Ecosystem, without the risks, time and costs of other methods. • The solution has been adopted in multiple businesses with excellent results and associated cost savings, as Mainframes are physically eliminated or downsized: Millions of dollars in savings based on MIP reductions have been seen.

    21. MetaScale Mainframe Migration Methodology • Key to our Approach: • allowing users to continue to use familiar consumption interfaces • providing inherent HA • enabling businesses to unlock previously unusable data 1 2 3 4 5 6

    22. Mainframe Migration - Benefits “MetaScale is the market leader in moving mainframe batch processing to Hadoop”

    23. Summary • Hadoop can revolutionize Enterprise workload and make business agile • Can reduce strain on legacy platforms • Can reduce cost • Can bring new business opportunities • Must be an eco-system • Must be part of an data overall strategy • Not to be underestimated

    24. The Learning Over two years of Hadoop experience using Hadoop for Enterprise legacy workload. • We can dramatically reduce batch processing times for mainframe and EDW • We can retain and analyze data at a much more granular level, with longer history • Hadoop must be part of an overall solution and eco-system • We developed tools and skills – The learning curve is not to be underestimated • We developed experience in moving workload from expensive, proprietary mainframe and EDW platforms to Hadoop with spectacular results HADOOP • We can reliably meet our production deliverable time-windows by using Hadoop • We can largely eliminate the use of traditional ETL tools • New Tools allow improved user experience on very large data sets IMPLEMENTATION UNIQUE VALUE

    25. The Horizon – What do we need next? • Automation tools and techniques that ease the Enterprise integration of Hadoop • Educate traditional Enterprise IT organizations about the possibilities and reasons to deploy Hadoop • Continue development of a reusable framework for legacy workload migration

    26.
