  19. 19. 19 IBM internal usage
  20. 20. • Deploying and Testing a build takes a long time • Installing the SMP/E build takes hours • Testing takes another couple hours • There’s also a zip build which doubles the install effort • SVT has to test in multiple z/OS environments 20 Challenges for the UrbanCode team
  21. 21. Auto build, deploy and test in 5 minutes The solution to these challenges Auto Deploy & TestIBM UrbanCode Deploy Rational Team Concert Selective Deploy Build Push builds Kick-off deploy z/OS 2.2DEV z/OS 2.1Primary Test z/OS 2.2 zD&T Extended Test z/OS 2.2 Performance Test z/OS 1.13 zD&T Extended Test
  22. 22. • Deploy time greatly reduced. – Build + deploy takes 5 minutes • Compared with several hours before • No manual deploy effort at all – Increased velocity • Allowed us to do 7 deployments a day last release, • Verification test effort greatly reduced – Automated build verification, failure notification by email • Shift left testing, fewer/no conflicts in integration – Before this, we merged multiple changes into one deploy, leading to conflicts and complexity in problem diagnosis – Now individual changes are tested independently • The real benefit: Developers now focus on developing new features and fixing bugs. They are much more productive and are focused on the tasks that they enjoy. 22 The benefits of the solution
  23. 23. – Support early version of zNext architecture in zPDT – Long before production GA level release of zPDT and availability of real hardware machine with these capabilities. – Currently only CPU architecture/facilities. – Available only to IBM internals for confidentiality and security under DOU control. – zPDT Team sets up Central Servers for group access, or can have single user lap-top version 23 𝑧𝑃𝐷𝑇 − 𝛼 (Alpha Driver)
  24. 24. • zPDT engineers work closely with the developers of the SAK (System Architecture Kernel) program • SAK is the key test vehicle used in zNext Bring Up • SAK & zPDT collaborate on initial Architecture implementations • Once we are both satisfied that emulation of a feature/instruction is working correctly, we make it available in the next zPDT Alpha code drop • Most IBM internal groups make use of Central Servers that the zPDT team sets up. These are very large configuration x86 servers with access to IBM File Sharing systems which users can load their code to (e.g. zOS images, new Compilers) • The Central Server concept allows us to control access and to more easily roll out new versions of the code. This is new in the current cycle and has made the zPDT Alpha code much more accessible to internal users. • zPDT team works closely with users and plans to conduct survey to review what we can do to improve. 24 Process to maximize use of alpha code (Shift Left Testing)
  25. 25. • zOS Development – able to test new architectural implementations several months ahead of HW access. Found and fixed several issues. • Linux on z – tested a number of new features • KVM for z – tested additional virtualization capabilities • Compiler team – able to build executables containing new instructions and test prior to HW being available • Research – several research users have experimented with enhanced security and vector capabilities 25 Groups Using zPDT − α
  26. 26. – Architecture flux/evolution sensitive • Potential for recode, rework, and/or discard of development/test depending on stability of architecture • User version management – Shift-left of development/test of software for new architecture support 26 Challenges
  27. 27. • Finding problems earlier!!! • zNext on a laptop or Central Server for personal/group development – Reduces need for hardware machines, scheduling development/debug time, etc. – zNext HW access is at a premium so being able to test SW via Emulation prior to HW availability really helps • Enables earlier software exploitation of new hardware features. Decreases time of software GA from new hardware GA. • Enables earlier development/test of various z ecosystem components – OS, service, performance, library routines, testcase generators, etc. prior to hardware availability on a high performance platform. • Validates architecture usage by OSes, services, testcase generators, etc. – Found various architecture areas needing resolution and updated architecture. • Differing interpretations • Deficiencies in scenario handling • Mutual benefit of early pre-validating/verifying zPDT for zD&T and ISV customers 27 Benefits
  28. 28. Interactive Poll # 2 28 Which of these use cases would be most valuable for your organization? • Prototyping • z/OS software betas or upgrades • Employee Education / Skill Building • Distribution and isolation of development and test activities • Enabling Agile Development methodologies for z/OS • Providing mainframe access for geographically dispersed teams • Application demonstration
  29. 29. 29 zD&T Benefits • Insufficient mainframe Dev & Test LPAR availability leads to defects and missed schedules • Tightly controlled mainframe environment prevents agile experimentation and prototyping • High cost of mainframe development and test hardware and software • Skill gaps due to off shoring, outsourcing and the majority of skills being near retirement Business Challenges Business Benefits Cost Savings Lower cost dev/test LPARS: Additional capacity necessary for adopting DevOps practices available on Intel compatible hardware MIPS reallocation : Initial Dev & Test activities performed on zD&T enables reallocation of MIPS to higher value production workload Economical training platform: Portable, indestructible environment for skill building Quality Shift Left testing : Better test coverage earlier in the cycle on high fidelity z/OS Dev & Test environment leads to quality and quicker delivery Work in parallel vs serially: Distributed environments reduce errors caused by contention and enable easier problem determination on easily provisioned systems Agility Adapt to changing business requirements : z/OS on x86 hardware that can be virtualized and reset offers a developer sandbox for prototyping and V2V migration Portability: Teams can Dev & Test z/OS applications anytime, anywhere. Outsourced teams can work without mainframe access.
