1. DevOps for the Mainframe
Leveraging continuous integration testing, the cloud, and
beyond to deliver z/OS applications

February, 2013

2. Please note
IBM’s statements regarding its plans, directions, and intent are subject to change or withdrawal without notice at IBM’s sole discretion.
Information regarding potential future products is intended to outline our general product direction and it should not be relied on in making a purchasing decision.
The information mentioned regarding potential future products is not a commitment, promise, or legal obligation to deliver any material, code or functionality. Information about potential future products may not be incorporated into any contract. The development, release, and timing of any future features or functionality described for our products remains at our sole discretion.
Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user’s job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

3. Why we need DevOps on the Mainframe
“Business software … has become horrifically complex”
“Developers are good at new functions, but bad at ensuring nothing goes wrong when the new software is added to the existing mix”
“No single group of people, can ever fully understand the structure of key business transactions in an enterprise”
In 2013 alone
Major 2012 events
“users to face duplicate charges”
“’system issue meant over 400,000 trades had failed to fulfill its best-price guarantee.”
“glitch delaying wage and bill payments”
“bungled update to CA-7 batch processing software costs over £100M”
“flash trading error causes $440M loss – due to dead code being accidentally triggered”

4. Mainframe Delivery Pains…
Bad code going into production causes crit sits and emergency fixes
Manual dependency management and configuration tasks result in errors and delays
Restricted dev and test capacity lead to conflict, delays, or bad test results in shared environments
Bottlenecks due to inefficient communications between disparate platforms and teams (Dev/Test - System Programmers; mobile – distributed-mainframe)

13. Separate tools makes collaboration inefficient or difficult...
Tool A Dev work Items
Each tool came with its own
UI - Web and desktop presentations of views and tasks
Logic – Workflow, process, search, query, scale, security and collaboration
Storage – Availability, traceability
Privacy, backup/archive
Resulting in...
Brittle integrations
Silos everywhere
High cost to maintain and administer
Proprietary API's
Tool B Release Planning DB UI

14. …consolidate, standardize, and simplify to increase collaboration
Engage all stakeholders in early planning, share and make visible
Enterprise Applications have thousands of disparate parts
Currently maintained in separate systems
Limited linkage between systems for application dependencies
Missing assets and information is rampant
