  • CASE STUDY GE CAPITAL ASSESSING, CONVERTING, & REPLATFORMING a MASSIVE BUSINESS CRITICAL APPLICATION with ASTONISHING RESULTS Introduction
    CASE STUDY GE CAPITAL ASSESSING, CONVERTING, & REPLATFORMING A MASSIVE BUSINESS CRITICAL APPLICATION WITH ASTONISHING RESULTS Introduction GE Capital is the financial services unit of the American conglomerate General Electric, it provides commercial lending and leasing, as well as a range of financial services for consumers. Most of GE Capital’s commercial loans are to small and midsized companies, spread across multiple industries and geographies, and secured by tangible assets. GE Capital’s consumer lending activities are also diversified by product and geography and include operations in 55 countries. Project Summary GE Capital was looking to move their PMS suite of $ 2014 Net Income: $7.0 billion applications from ADS/O and COBOL/IDMS running 2014 Assets: $499 billion on a mainframe, to COBOL running with Oracle on Unix without changing the user interface in the Operations in 40+ Countries process. PMS was built by GE Capital in 1987 500,000+ Commercial Customers and began its life as a 20,000 account schedule system without any interfaces. 35,000+ Employees As with most homegrown systems, it was built out of necessity and to serve the business as it existed at the time. Over the decades, this small system grew in size and complexity to become the central nervous system of both GE Capital’s direct and indirect business units comprised of four highly customized implementations. With over 5 million account schedules, 382 interfaces, 1,700 concurrent users, and 3.5 million transactions per day running against 71 million lines of code, the PMS system had come a long way from its humble roots.

  • Mainframe Modernization: What Are My Choices?
    e BOOK Mainframe modernization: What are my choices? Choosing the best legacy modernization option for your organization For decades, most large-scale companies have used mainframes to host and run the software applications that make up their legacy systems. Indeed, most enterprise-level systems in operation today reside within mainframe machines, while COBOL applications (the primary language used with mainframes) continue to handle the vast majority of modern enterprise-level computer transactions. But analysts today emphasize that CIOs need to speed up legacy modernization in their organizations for many reasons, not least of which are remaining competitive and being able to respond quickly to market threats and opportunities. Industry analysts recommend that IT directors take inventory of their portfolio of existing systems in order to divide them into three categories. This exercise can help IT focus on improving its digital business focus: Systems of record Systems of differentiation Systems of innovation These can be purchased as packaged systems Typically, these are internally developed These systems provide true company value or internally developed, and typically they and provide some level of distinction from and often its Intellectual Property. This is do little to company competitiveness. An the competition. An example might be an where innovation needs to be focused and example might be back office accounting. improved customer interface and experience. budgets spent. An example can be a risk rating system for insurance companies. The next step is to look at the percentage of budget each category currently absorbs. If too much is being spent on Systems of Record (typically mainframe applications), and not enough is being spent on Systems of Innovation, your competitors are probably closing in.

  • A TCS Perspective on Mainframe Re-Hosting About the Authors
    Alliance and Technology Unit White Paper A TCS Perspective on Mainframe Re-hosting About the Authors Ajay Gupta Ajay is an Enterprise Architect with the Alliance and Technology unit at TCS. He has been in the IT industry for over 18 years. He has worked on application development, maintenance, and database migration initiatives on mainframes, as well as application migration off mainframes. Since 2007, he has been working extensively on IBM mainframe re-hosting. His responsibilities include legacy landscape assessment, target architecture definition, capacity planning, business case preparation, migration planning, and project delivery support. He has a Bachelor’s degree in Electronics and Communication Engineering from Pondicherry University. Sujeet Babu Sujeet is a Solution Architect with the Alliance and Technology unit at TCS. He has been in the IT industry for over 16 years, and has worked extensively in mainframe-based application development and maintenance projects for customers in North America, Europe, and the UK. For the last six years, he has specialized in helping TCS customers with their legacy modernization initiatives, particularly related to IBM mainframe re- hosting. Sujeet holds certifications in DB2, SOA, ITIL, Six Sigma, Enterprise Architecture (TOGAF ), Agile (IBM RUP), and General Insurance (from the Chartered Insurance Institute, UK). He has a Bachelor’s degree in Electrical and Electronics Engineering from Bangalore University. Abstract Mainframes form the backbone of many core business processes in organizations worldwide. However, the total cost of ownership, platform flexibility, and administration and programming skills associated with them have been critical areas of concern in recent times. Banking solely on unsupported legacy systems might not just create reliability and performance issues, it could also lead to more revenue leakage due to the high cost of maintenance.

  • A Mainframe Rehosting Solution
    A Mainframe Rehosting Solution A rehosting solution that automatically migrates mainframe programs to an open system environment without modifications REHOSTING OpenFrame A Mainframe Rehosting Solution Migrates mainframe programs without modifying the source code for use in an open system environment. Provides compilers and an integrated assets management environment for automated migration. OpenFrame is a rehosting solution that migrates existing mainframe programs without What's modifying the source code for users in a reliable and high-performance open system environment. It provides an optimal open system environment at minimal cost through OpenFrame future-oriented standard architecture, automated migration, compilers, and an integrated assets management environment.

Flexibility 3-tier Architecture Separates the UI from the AP to flexibly respond to changes. (Changing the UI does not require modifying the AP.) Client Using integrated UI ▼▲ Scalability UI Separation (User Interface) Easy to integrate APs, increasing AP scalability. ▼▲ AP (Application) Efficiency ▼▲ Efficiently handles business since an AP DATA does not process the UI. Automated Conversion Provides advanced compiler technology that implements automated conversion and enables reliable migration to an open system environment at minimal cost.
