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.Batch workload can be migrated and run anytime in a fraction of the clock-time leveraging Hadoop.
6 Batch Processing 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 producedImmediate 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 storageAvailable processor capacity, or cyclesjob schedulingProgramming utilities to process basic operations (Sort/Filter/Split/Copy/Unload etc.)
8 Why Hadoop and Why Now? THE ADVANTAGES: THE CHALLENGE: THE SOLUTION: Cost reductionAlleviate performance bottlenecks ETL too expensive and complexMainframe and Data Warehouse processing HadoopTHE CHALLENGE:Traditional enterprises lack of awarenessTHE SOLUTION:Leverage the growing support system for HadoopMake Hadoop the data hub in the EnterpriseUse Hadoop for processing batch and analytic jobsBatch workload can be migrated and run anytime in a fraction of the clock-time leveraging Hadoop.
9 The ArchitectureEnterprise solutions using Hadoop must be an eco-systemLarge companies have a complex environment:Transactional systemServicesEDW and Data martsReporting tools and needsWe needed to build an entire solution
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

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 interfacesproviding inherent HAenabling businesses to unlock previously unusable dataImplement a Hadoop-centric reference architectureMove enterprise batch processing to HadoopMake Hadoop the single point of truthMassively reduce ETL by transforming within HadoopMove results and aggregates back to legacy systems for consumptionRetain, within Hadoop, source files at the finest granularity for re-use123456

23 SummaryHadoop can revolutionize Enterprise workload and make business agileCan reduce strain on legacy platformsCan reduce costCan bring new business opportunitiesMust be an eco-systemMust be part of an data overall strategyNot to be underestimated
24 The LearningOver two years of Hadoop experience using Hadoop for Enterprise legacy workload.We can dramatically reduce batch processing times for mainframe and EDWWe can retain and analyze data at a much more granular level, with longer historyHadoop must be part of an overall solution and eco-systemHADOOPWe can reliably meet our production deliverable time-windows by using HadoopWe can largely eliminate the use of traditional ETL toolsNew Tools allow improved user experience on very large data setsIMPLEMENTATIONWe developed tools and skills – The learning curve is not to be underestimatedWe developed experience in moving workload from expensive, proprietary mainframe and EDW platforms to Hadoop with spectacular resultsUNIQUEVALUE
25 The Horizon – What do we need next? Automation tools and techniques that ease the Enterprise integration of HadoopEducate traditional Enterprise IT organizations about the possibilities and reasons to deploy HadoopContinue development of a reusable framework for legacy workload migration
