DB2 10 for z/OS Update

  1. 1. Why DB2 for z is the best for you? Cüneyt Göksu, DB2 SME, IBM Gold Consultant [email_address]
  2. 2. Agenda 1. Big Data 3. How existing Data Management Architectures and platforms meet this data growth? 2. Absolute Musts of Data Management 4. DB2 10 for z/OS 5. Maturity of platform differs!
  3. 3. Data Flow becoming... Instrumented Interconnected Intelligent
  4. 4. The situation at a glance “ The industrial revolution of data” Joe Hellerstein, a computer scientist , University of California in Berkeley Time Growth of Computing Power New Information All Digital Data Sensemaking Algorithms Growing Amnesia Index?
  5. 5. Information flow defines BIG DATA...
  6. 6. How Big is Big Data?
  7. 7. How Big is Big Data? Enterprise data doubling every 3 years Storage capacity continue to increase dramatically - access speeds have not kept up At avg. transfer speed of 500 MB/sec - 1 TB of data will require ~30 mins to read from single drive
  8. 8. How Big is Big Data? Wal-Mart : 1M customer txs/hour, feeding 2.5 PB databases Facebook : 40Billion photos and increasing... Big Turkish Bank : 200 M txs/day, 0.06 second/tx UK Land Registery : The world’s largest known OLTP database – 71 TB at UK Land Registry
  9. 9. Existing Platforms and BIG DATA Decentral Central versus
  10. 10. Absolute Musts of Data Management Scalability Availability and DR Security Productivity , Utilization and Performance System Management Labor, Skills and Resources Green IT
  11. 11. Scalability i s the ability of a system to handle growing amounts of work in a graceful manner or its ability to be enlarged to accommodate that growth Scale-out or Horizontally Scale-up or Vertically
  12. 12. Availability and Disaster Recovery ... measures are classified by either the time interval of interest or the mechanisms for the system downtime Financial Impact of Downtime Per Hour What’s yours?? $704K Chemicals $669K Transportation $786K Consumer Products $997K Banking $1,082K Pharmaceuticals $1,107K Retail $1,202K Insurance $1,345K Information Technology $1,495K Financial $1,611K Manufacturing $2,066K Telecommunications $2,818K Energy Cost Industry segment 2h 11m 15h 20m Annual outage $3.3M $22.9M Cost of Downtime 99.975% 99.825% Availability % Central Decentral
  13. 13. Security protecting information from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction . Last Year , Oracle issued 45 security patches Decentral Central 25 + Years of Secure Operation! In 20 years , DB2 for z/OS has had less than 5 security patches
  14. 14. Productivity , Utilization and Performance Utilization is the proportion of the system's resources which is used by the traffic which arrives at it Specific/Single Workload Mixed Workload Shared Nothing Shared Everything %15-20 Utilization %85-90 Utilization Decentral Central
  15. 15. System Management and Labor System Management is enterprise-wide administration of systems Is it true ? >:::> More Data needs More DBAs and System Management efforts! it highly depends!!! Running on Decentral or Central.
  16. 16. Green IT is environmentally sustainable computing . More Servers Less Servers More Power Less Power More Cooling Less Cooling Decentral Central More Space Less Space
  17. 17. BIG DATA management with DB2 for z/OS “ DB2 for z/OS” is IBM’s 25+ years old flagship database Used by; 62 of the top 62 WW banks 2 4 of the top 25 US retailers Over 100 of the largest Government ’ s in the world 9 of the top 10 global life/ health insurance provider s
