The backbone of the futuristic DevOps ecosystem is CI-CD Pipeline
implementation belonging to the Continuous Integration/Continuous
Deployment Software. The pipeline has a great influence on the software
and applications by way of providing periodic and steadfast updates to
them. In addition, it provides an agile and collaborative workflow for
the entire DevOps squad.
With the help of test automation, CI/CD pipeline identifies the
estimated issues way before anyone can find out, push codes the changes
to different environments, and provides applications to the production
environments. From performance to API and security, test automation
analyses and assesses anything. This further becomes the most crucial
source for pipeline quality control.
Know the differences between CI, CD, and CD?
It is a software development method where the team members can unite
together for a minimum of one time a day. Here, an automated build to
search tool assesses every small unification or integration with an aim
to find out the errors.
Pros of CI (Continuous Integration)
Automated monitoring of codebase, code coverage metrics, and code
- Low maintenance expenditure and keeps down the technical debts
Developers get a boost to enhance code quality with publicly-visible
code quality metrics
A candid overview of the present scenario of development efforts is
known with automated end-to-end acceptance tests.
Lesser risks over a period of time due to the quick feedback
Tools created to facilitate trace and fix integration and regression
issues quickly so as to avoid more bugs and ensure fast delivery
Enables simplification of delivery and amplifies it through
automation of deployment process. With this in place, the testers and
end-users get quick access to the software.
CD is a process of software engineering whereby a group of developers
creates software within a short time span to ensure its quick delivery
at a given time.
Pros of CD (Continuous Delivery)
Lesser Risks: The aim of CD is to develop effortless software
deployments and make low-risk events that can be performed whenever
Quicker Time to Market: Every integration and test/fix phase
of the traditional phased software delivery lifecycle takes time more
than weeks and months.
Decrease in Costs: The growth of any software product or
service occurs only after a considerable time span of usage and the
experience of its results
Sound Products: CD is inexpensive in terms of working within
small batches. You can take feedback from its users through the entire
delivery lifecycle depending on the working software.
Joyful teams: When the research gets a fair review from
counterparts and peers, you improve with a continuous delivery that is
less painful and decreases team burnout.
This is another process of software engineering delivering
functionalities with automatic deployment. The testers get support for
validating the codebase changes and ensuring their correctability and
CD also can be considered as a step ahead of Continuous delivery
wherein each change in the source code is deployed to production
automatically with no approval needed from a developer.
Pros of CD (Continuous Deployment)
Software release process automation: CD allows your
developers’ group to automatically create, test, and make code changes
for production release in order to deliver the software with speed and
Accelerates Developer Productivity: Your team gains higher
productivity by making it more independent from doing manual tasks and
promoting behavior that ensures error reduction and lesser bugs
deployed to the customers
Traces and Addresses bugs quickly: Your team gets enabled to
track and address the bugs quite before they become a big problem
leading to frequent and aggressive testing. CD also allows flexibility
to execute extra tests on your code with an intention to automate the
Quick Delivery of Updates: CD facilitates the team to provide
regular updates to the customers with speed and frequency. With proper
implementation, the CD can give you a deployment-ready build artifact
gone through a rigorous testing process.
Stages of CI/CD Pipeline
The importance of CI/CD pipeline dwells in the steps with runnable
specifications. These steps are required to be performed to ensure the
delivery of the new version of the software product. Generally, CI/CD
version comprises following stages:
Some common CI/CD tools
CI/CD tools assist the team to automate the development, testing, and
deployment of the software. There are certain tools handling the
integration (CI) side, while some handle the development and deployment
(CD). The others develop a specialization in continuous testing or
The most popular open-source tool for CI/CD is the
Automation Server Jenkins. Jenkins is created with an aim to
manage and control everything beginning from a simple CI server to a
fully operational CD hub.
The fundamental tools of DevOps mostly become a part of CI/CD process.
For example Configuration Automation (like Chef, Ansible, and Puppet),
Container Orchestration (such as Kubernetes), and Container Runtimes
(like Docker, CRI-O, and RKT). All this also shows up in several CI/CD
During the usage of CI/CD, the code quality gets augmented and there is
a quick delivery of software updates. All this happens with great
assurance of no breaking changes. For every release, its influence is
definitely correlated with data starting from production and going
