IBM’s approach to Mainframe Modernization

2. Code, Build & Deploy
 Adopt Application Discovery and Delivery Intelligence(ADDI) to analyze and visualize relationships of z/OS application components.
components. (Impact Analysis during requirement phase)
 Leverage IBM DAT (Data Accelerator Team) on helping migrating the code repository from Mainframes to Github
 Effective collaborative development tools and processes enabled through IBM Development for z (IDz) , DBB and zUnit. With a single click
single click of a button compile, build and run predefined testcases automatically
 Automate deployment with IBM UrbanCode ™ Deploy and automate self-service provisioning with Cloud Provisioning and Management
Management for z/OS
Test
Automated testing provided by IBM Z Development and Test(zD&T), IBM Z Virtual Test Platform (zVTP)
• Automate shift-left testing of online transactions and batch programs early in the development lifecycle, without the need for artifacts to
artifacts to be deployed in the target environments
• Full Stubbing - Record, Intercept, and stub out a variety of subsystem and program-to-program calls.
• Save your tests in a Software Configuration Management (SCM) tool or artifact repository system and incorporate tests into a continuous
continuous integration and continuous delivery (CI/CD) pipeline
• Enables IBM zOS MW and other software to run on Intel compatible platforms(x86) without the need for IBM Z hardware/MW (CICS/DB2).
(CICS/DB2). Emulates the z Architecture with virtual I/O devices. Can be used for Testing, Training and Development environments

• Accelerate Mainframe Application Development, Test and Education, Gain the cost advantages of a distributed development and test
and test system while freeing up mainframe capacity for more valuable production workloads.

A modern DevOps workflow is
founded on sound Agile practices
and leverages tools and skills to
streamline all phases of the
process. It fosters a culture of
cooperation and efficiency across
all levels of support – Business
