Is the mainframe still relevant?

Some people may not think so because:

• The “face of the mainframe” is too often still a green screen.

• Their view was frozen years ago.

• They have no experience with the mainframe.

In 1991 Stuart Alsop wrote this in InfoWorld:

“I predict that the last mainframe will be unplugged on March 15, 1996.”

Digital transformation requires Hybrid Cloud + API Management + DevOps

• Maximize enterprise value by balancing the use of internal assets and external services at scale• Expose business critical services through APIs as your platform agnostic language within the context

of a hybrid cloud

• Modernize business critical applications to gain business agility• Componentize them leveraging java, system APIs and Micro services

• Evolve applications and services at the speed of business• Leverage a cross-platform DevOps solutions to gain necessary speed and agility

Continuous Integration/Testing/Delivery and Typical Mainframe Environments

• Continuous Integration: The process of integrating changes quickly and automatically so that end to end testing can be done at all times to catch errors before the application is put into production (manageable defect detection throughout the lifecycle)

DRIVES…

• Continuous Testing: Automated testing as part of the software delivery pipeline

DRIVES…

• Continuous Delivery: Ensuring that code can be rapidly delivered to production without compromising on quality

Keep the build fast

Test in a clone of production

Make it easy to get latest deliverables

Visibility into latest build results

Defect cost derived in assuming it takes 8 hrs to find, fix and repair a defect when found in code and unit test. Defect FFR cost for other phases calculated by using the multiplier on a blended rate of $80/hr.

Automated Delivery Pipeline: Summary

Key differentiators

• Industry’s only delivery pipeline

– going from Idea to Deploy. No need to buy, integrate and maintain integration of multi-vendor solutions

– with multi-platform collaboration and multi-platform SCM

– offering extensive 3rd-party integration support through Open-Software Lifecycle Collaboration (OSLC)

– with multi-platform deployment support

– with native z deployment support (deploying load modules, support for CICS, IMS, MQ and DBRMs, integration with Job schedulers, ability to track multiple versions of load modules, and allowing rollback)

• TechValidate research (UCD) , Client references for UCD and RTC• IBM is a leader! Ovum Decision Matrix: DevOps Release Management, ALM,

• DevOps is about transforming application development and delivery to accelerate digital innovation. DevOps affects both business and IT roles in the organization.

• You don’t buy DevOps, you do DevOps. DevOps is an approach, a mindset – a combination of culture, process and technology solutions that enable the transformation.

• DevOps is not limited to the hand-off between Development and Operations. DevOps is about applying lean and agile principles across the application delivery lifecycle (biz-dev-test-deploy-operate) to achieve continuous delivery. Key concepts: automation, feedback loops.

• DevOps culture change has to accompany process and tools change!
