1. The Mainframe Is Dead, Long Live The Mainframe
Craig Hodgins

2. Batch – 1960’s

3. TSO – 1970’s

4. Online – 1970’s to 1980’s

5. PC Age – 1980’s to 1990’s

6. Prediction #1
“I believe OS/2 is destined to be the most important operating system, and possibly program, of all time.” Bill Gates, 1987

7. Prediction #2
“The last mainframe will be shut down by 1996” Stuart Alsop,
HAL9000 became operational on 12 January 1997

8. Cloud – 21st Century
The mainframe is still alive because business-critical applications run there
80% of business data is stored on mainframes
200 billion lines of COBOL (adding 5 billion a year)
1 trillion dollars of application value
50 billion devices connected to z/OS by 2020
43 billion banking transactions in 2013
The mainframe evolved
Unix
Linux
Petabytes of data
The cloud providers are trying to recreate the mainframe on another platform

9. The web did not kill print
MP3s did not kill the record industry
The mobile phone did not kill the desktop
Cloud computing has not killed off the mainframe
The mainframe is a 50 year old machine that has evolved and improved
You could say the mainframe of old really is dead, but adapting to each new IT disruption has changed it into a different beast

10. z/OS Market Trend MIPS vs. Customers
Overall MIPS utilization within the market is expected to grow…
…while small and some medium customers are anticipated to leave mainframe environment.
10,000 mainframes worldwide

11. Prediction #3
“I think there is a world market for maybe five computers." Thomas Watson, chairman of IBM, 1943

12. Growth of Corporate Mobile Apps

13. Increasing Transaction Volume
Consumer driven transactions introduce 24x7 workload demand.

14. Performance Still Matters

15. “A slow application is a down application”
UPS Blue Christmas
“A slow application is a down application”
Before Christmas last year UPS was struggling delivering packages. Customers were repeatedly checking from their mobile devices to see where their packages were.  Every day people were sending 2, 3 or more requests to get an update on their package status.  Each request sends an MQ message to the MF which gets processed in CICS before sending it back to the user.   The CICS regions failed to keep up with the new increased activity.

18. Open-systems Impact on Mainframe

19. 66% of CIOs fear the impending retirement of the mainframe workforce
Aging Workforce
66% of CIOs fear the impending retirement of the mainframe workforce
40% of CIOs have no formal plans in place to handle mainframe skills shortage.

20. Mainframe Landscape 2014 – What’s changed?

21. What Shall We Do Now?

22. Compuware Mainframe 2014 – What’s New!

23. DevOps in a Nutshell DevOps is confusing Faster is better
Software is the interface for consumption
Test in production
Failures will happen
Give people tools and trust them
Measure everything
Gather feedback
Share knowledge

24. Why DevOps and Why Now? US Air Force dog fight victory study
The answer was not a faster jet
The answer was not more fire power
The answer was the pilot that could react to change faster won most of the time

25. Why DevOps and Why Now?
It’s all about reducing cycle time between delivering software updates
Software automates the business process
Software extends the business functionality
Software disrupts the business model (massive change in a short period of time)

26. Why DevOps and Why Now? It’s all about a competitive advantage
AMEX is afraid of Apple Pay because the latter can respond faster to customer needs
Software rollout horror story
7 departments involved in a single release deployment that took 3 months
DevOps is critical to business survival
Continuous delivery is all about removing the bottlenecks that stop you from delivering value to the customer.

27. Agile Agile is part of DevOps but is not DevOps
Agile does not mean doing more with less
Compuware is going agile

28. The Best Place to Test is in Production
Deploy code to 1 or 2 servers
Enforce failures and see what happens
It is a controlled environment
It is easier to restore service with experts at the ready than at 3:00 AM
You need to test the defect-handling code!
Need to discover what normal looks like when things are abnormal
If you do not proactively test failure your customers will test it for you.

29. Computers are useless. They can only give you answers.
A Final Thought….
Computers are useless. They can only give you answers.
