Indroduction
CI/CD (Continuous Integration and Continuous Delivery/Continuous Deployment) is a modern software development practice in which incremental code changes are made more frequently and reliably by introducing automation into the stages of continuous delivery.
The term – for continuous integration and continuous delivery (sometimes the "D" also can mean "deployment") – emerged in the late 2000s with the rise of DevOps, defining a way to more quickly create and update applications by leaning heavily on automation for everything from building to testing to deploying systems, pulling together contributions from myriad contributors into a pipeline, and speeding up release cycles.
Software is no longer built by a single developer on a single machine; instead, developers using disparate tools can contribute to the build within the pipeline without causing conflict. Organizations don't have to wait for software updates to be gathered together into a single large batch to be released at a set time and updates and improvements can be pushed out as soon as they are ready.
Builds are standardized, security shifts from shared to increasingly isolated resources and checks can be run on every change, and value is more quickly delivered, it's claimed. With CI/CD came a greater reliance on automation and infrastructure-as-code (IaC), more third parties being involved, and new frameworks and languages becoming rapidly adopted.
Most popular CI/CD pipeline :
There’s other open source CI/CD tools you may wish to investigate include:
- Spinnaker, a CD platform built for multicloud environments.
- GoCD, a CI/CD server with an emphasis on modeling and visualization.
- Concourse, "an open-source continuous thing-doer."
- Screwdriver, a build platform designed for CD.
Teams may also want to consider managed CI/CD tools, which are available from a variety of vendors. The major public cloud providers all offer CI/CD solutions, along with GitLab, CircleCI, Travis CI, Atlassian Bamboo, and many others.
I personally use github, i’ve used the CI/CD practice on the most of the hosted projects that i have worked on so far.

What are the benefits of CI/CD?
Organizations that practice CI/CD produce higher-quality software more quickly. Benefits of CI/CD include delivering software with less risk, releasing new features more frequently, faster response to customer feedback, and improved developer productivity.
