  9. History of the IBM Mainframe • Late 1980s prediction of replacement by Client/Server (C/S) Technology • Distributed Clusters of Servers • Linked to networks of PCs • Downsized Mission Critical Applications migrated to C/S platforms • Less expensive • More efficient • Faster Development • Easier to use

  10. History of the IBM Mainframe “The mainframe was announced as obsolete by a chorus of PC and LAN boosters, open systems vendors, and various media figures in the early 1990s.” “The Erosion of Mainframe Security”, Gartner Group

  11. History of the IBM Mainframe • Shortcomings of Client/Server Technology • Applications have not “scaled” up well • Good security is difficult to achieve in a distributed environment • Total Cost of Ownership has skyrocketed • Cost of Ownership Per User Comparison • Taken from The Dinosaur Myth (Xephon 2002) • Thousands of users • Over a five year period • Performing similar functions

  12. History of the IBM Mainframe • Shortcomings of Client/Server Technology

  13. Current State of the IBM Mainframe • Transition via z/OS and z/Series Servers • From Closed Legacy System only image • To Open E-Business and E-Commerce image • Began in 1996 with first release of OS/390 • Continues Legacy System Support • Exploding Open Server Enhancements • Unix System Services • Web Server • Lightweight Directory Access Protocol - LDAP • Cryptography and Secured Socket Layers • z/OS Firewall Technologies

  14. Current State of the IBM Mainframe • OS/390 and z/OS on the Web • East Coast Medical Insurance Provider • Intranet Web Site Access • Internet Web Site for Insured Clients • Coverage Inquiries • Claims Status • Internet Web Site for Physicians • Benefits to using z/OS Web Server • Fast • Availability • Not as susceptible to viruses

  15. Current State of the IBM Mainframe “Organizations should no longer think of S/390 as synonymous with MVS and legacy application paradigms. Through the incorporation of open industry standards such as HTML, HTTP, XML and J2EE-compliant Java technology, new e-business applications and transactions can now be developed for deployment on this platform.” Dale Vecchio, research analyst with Gartner Group

  16. The Mainframe’s “Re-birth” • Still home to between 70% to 80% of mission-critical legacy applications • 15-20% annual growth of installed processing capacity • Cost of mainframe computing driven down to highly competitive levels • Full integration of open computing and communications technologies • Number and types of applications spiraling • Now the “Super Server” for distributed computing and Internet commerce

  17. IBM Mainframe Growth Source - IBM Poughkeepsie

  18. New IBM Mainframe Environment • Hardware • Bipolar to CMOS (Complementary Metal Oxide Semiconductor) • Smaller, cooler-running systems to reduce environmental costs • 1997 - Generation 4 S/390 Parallel Enterprise Server • Equaled most powerful Bipolar system • 1998 - Generation 5 S/390 Parallel Enterprise Server • Up to 80% more powerful than most powerful Bipolar system

  19. New IBM Mainframe Environment • Hardware (continued) • 1999 - Generation 6 S/390 Parallel Enterprise Server • S/390 Parallel Sysplex Clustering Technology • Unlimited scalability and nearly continuous availability • 1.2 to 3.7 times lower cost than distributed UNIX systems (International Tech. Group (ITG) and Gartner Group) • 2000 - zSeries 900 • E-business enterprise server • Designed for high performance data transaction needs of e-business • 2002 - zSeries 800 • Entry level hardware targeted for Linux environments
