Example 1: what is ci

CI is a development methodology
where the developers commit changes to source code
in a shared repository. This typically takes place
several times a day. The benefit is that it enables teams to
find and resolve issues early in the development process.
There are many tools teams can use to
implement Continuous Integration. Depending on what they
choose, there are also other functions developers can take
advantage of such as using test servers and providing
teams with test results.
CI became a best practice method because of how much it
improves the final product. Most of the time, software
developers work in isolation. After they complete their work
and make changes, they need to integrate those changes
with work done by the rest of the team. This process is
usually drawn out, and the end result is conflicts that
developers have to resolve and less productivity overall.
Continuous Integration helps to eliminate these problems.
The CI method ensures that bugs can be found and fixed
early in the development process. When you use test
automation with CI, it also ensures that builds are
consistent.

WHAT IS CI/CD PIPELINE
Pipeline is a set of processes that take 
the code from version control and build,
compile, test and deploy to production
in automated fashion. The pipeline breaks
down the software delivery process into stages.
Each stage is made of different tasks
which can be carried out in parallel.
When all tasks in a stage passes, 
next stage is triggered.
The CI/CD pipeline is one of the best 
practices for DevOps teams to implement,
for delivering code changes more frequently and reliably.

MAIN GOAL OF THE CI/CD is providing 
shorter release cycle. So, end users 
can get new version of application
with new features of fixed bugs and
better application.
