CI/CD is a method to frequently deliver apps to customers by introducing automation into the stages of app development. The main concepts attributed to CI/CD are continuous integration, continuous delivery, and continuous deployment. CI and CD stand for continuous integration and continuous delivery/continuous deployment. In very simple terms, CI is a modern software development practice in which incremental code changes are made frequently and reliably. Jenkins is undoubtedly the most well-known tool for building CI/CD pipelines. A robust, open-source project, Jenkins has a devoted community worldwide.
What is CI Tools?
Continuous integration (CI) is the practice of automating the integration of code changes from multiple. Developers input code into their private terminals. After that is done, they commit the changes to the shared repository. The CI server monitors the repository and analyses changes as they occur. contributors into a single software project. Software developers often work in isolation and therefore the advent of CI is a great practice when working in a team because prior to the emergence of Continuous Integration, it took days or even weeks for software developers to integrate their code and also to merge changes from different branches of code. These long periods of time created many merge conflicts, stubborn bugs, code strategy divergence and duplicated effort. CI requires the team’s code be merged to a shared control branch, continuously, to avoid these problems.
How Does Continuous Integration Work?
- Developers input code into their private terminals.
- After that is done, they commit the changes to the shared repository.
- The CI server monitors the repository and analyzes changes as they occur.
- Continuous Integration builds the system and runs unit and integration tests.
- The server also releases deployable artefacts for testing.
- The CI server assigns a build tag to the version of the code it just built.
- The Continuous Integration server gives the team reports of the successful build.
- If the build or tests fail, the server alerts the development team.
- The team will fix the issues as soon as is possible.
- It continues to integrate and run tests throughout the entire project.
What is CD Tools?
A CD tool should allow you to incorporate your existing test automation (regression testing, etc.) into a pipeline. Change Management, Governance, and Approvals – This step is how a company designates what’s ready to be deployed to production. Continuous Delivery is the process of deploying build artifacts into an environment. An example of an artifact is a docker container, and the environment could be for testing or for production.
Continuous Delivery tools help create pipelines to standardize releases. Fundamentally, pipelines can be broken down into five stages:
- Testing and QA
- Change Management, Governance, and Approvals
- Deployment Strategies
Benefits of CI Tools?
Continuous integration (CI) is the practice of automating the integration of code changes from multiple contributors into a single software project. It’s a primary DevOps best practice, allowing developers to frequently merge code changes into a central repository where builds and tests then run.

Benefits of CD Tools?
Continuous Integration (CI) allows you to continuously integrate code into a single shared and easy to access repository. Continuous Delivery (CD) allows you to take the code stored in the repository and continuously deliver it to production. CI/CD creates a fast and effective process of getting your product to market before your competition as well as releasing new features and bug fixes to keep your current customers happy.
