Traditional Integration
▪ Greater time gap in case of Traditional Integration
▪ Relatively greater risk or change in conflicts

Problems With Traditional Integration
Should I
rewrite the
whole code?
Why am I getting
the latest version of
the code so late?
Oh my god!
All the
implementation
details have changed
Why is the entire
subsystem of the
application behaving
in different way?
Is there any other
way around to
manage all these
changes ?
What happened to
the last API version?
How am I going to
manage all the
changes?
How will I
escalate the
project?

What’s the Solution?
Split the entire
chunk of codes
into segments
Integrate the
segmented code,
multiples times a day
Keep small
segments of
manageable code
Adopt a continuous
integration methodology to
coordinate with your team

What is Continuous Integration?
Continuous Integration is a software development practice
where members of a team integrate their work frequently,
usually each person integrates at least daily – leading to
multiple integrations per day. Each integration is verified by
an automated build (including test) to detect integration
errors as quickly as possible. Many teams find that this
approach leads to significantly reduced integration problems
and allows a team to develop cohesive software more rapidly.

Reduced Integration Risk
Higher Code Quality
The Code in Version Control Works
Reduced Friction between Team Members
Ease for QA Team
Less Deployment Time

Jenkins – The Ultimate CI Tool
Jenkins is an open source automation tool written in
Java with plugins built for Continuous Integration
purpose. Plugins allows integration of various DevOps
stages.

Jenkins Plugins
Jenkins achieves Continuous Integration with the help of plugins. Plugins allow the integration of
Various DevOps stages
Plugin Categorization
Test Reports Notification Deployment Compile

Hands-On
We will be Fetching the path of our project from git hub repository and provide it to Jenkins. It will build your
project. CI will come into the picture when you build your project after a fixed interval of time which you can define
by yourself using poll SCM. After that we will be building a Jenkins Pipeline to show Continuous Delivery.
