Why ?
Enables customers adopt DevOps on Mainframe, bridging
traditional development practices with agile methodologies and
improving the operation to be more resilient in order to keep
legacy up to speed with modern-distributed and make the
application meet business agility
DevOps – DELIVER WITH SPEED
Everyone is responsible for delivering business value to users
Goals
 Quicker releases into production
 Faster feedback and minimal disruption
 Efficient and optimal software development
 Stable application
 Frequent Deployments
What is DevOps?
DevOps is an advocate for a IT mindset change , where the team communicates, collaborates in a manner where
they can work more closely with one another with focus on faster delivery using automation and shift left

DevOps on Z – Challenges And Solutions
Primitive tools and
processes causing delays in
impact analysis and
delivery
Lack of agile adoption across
heterogeneous architectures and
technologies increasing
development costs
No business insights about
costs, benefits & RoI of IT
spend & DevOps effectiveness
Inability to identify defects early
in the release

Case Study – I : Using CA Endevor with IDz
Challenges & Requirements
• For one of the large insurance customer, a development project involving 300+
mainframe developers was underway.
• Multiple deployments into the integration test environment with no checks on
code quality was a big concern.
• Manual build & deployments. Reduced time to market , productivity and high
effort
• Deployment automation with a single pipeline for Mainframe was also needed.
• Leverage mainframe investments to keep pace with digital economy
Accomplishments
• Implemented CI/CD DevOps Pipeline using Jenkins for 400+ Mainframe Applications. Deployed
IDz with Sonarlint for the code quality check
• Enforced Quality Gating based on the SonarQube Analysis and generated SonarQube reports.
Code promotion is allowed only if the source code passes the Quality Gating
• 1 day turnaround time for deployments is now automated and completed in minutes
• ~30% improvement in developer productivity
