CI/CD: Understanding the Basics and How It Can Improve Your Software Development

Discover the benefits of CI/CD for software development teams. Our guide explains the basics of Continuous Integration and Continuous Delivery, including the pipeline stages, tools, and technologies involved.

CI/CD: Understanding the Basics and How It Can Improve Your Software Development

A pipeline is a procedure, often known as CI/CD, that directs software development along a path of creating, testing, and deploying code. The goal of automating the procedure is to reduce human error and keep the software release process consistent. Techniques for code compiling, test automation, code, safety, and binary production may be included in the pipeline. This process would also include bundling the code as a container image for deployment across a cloud system in containerized settings.

A DevOps methodology's foundation is CI/CD, which unites teams from IT operations and development to deploy software. The speed at which code can be published has evolved into a competitive differentiator as app developers become essential to how businesses differentiate themselves. 

What is CI? 

A process called continuous integration unifies the technologies used throughout the DevOps lifecycle. The source control system is accessed by the continuous delivery tool to retrieve the code. The code is developed and tested whenever a developer edits it.

Continuous integration tools send the programme to the production server after it passes the testing step, where it is then distributed to the client. Customer input is recorded in the monitoring tool, and the entire process is automated utilising tools and merged using a continuous integration tool.

What is a CD?

Software development, construction, testing, and deployment are all steps in the continuous delivery process. A developer edits the source code, a continuous deployment tool pulls it, and then pushes it to a building and test server to begin the process.

The system is installed to the manual check stage after successful testing, and after the operator approves it, it is then deployed to the production server, where it is made accessible to the client.

Differences between CI & CD?

Software delivery through automation is done using a process called continuous delivery in DevOps. Continuous integration (CI) is a phase connecting elements in a structure that established the DevOps lifecycle, whereas continuous delivery (CD) encompasses many steps associated with software production, notably developing, testing, and deploying.

Software is sent to a human approval stage once it successfully completes the testing stage, where it is taken into account along with other considerations including company strategies and update requirements. The most crucial aspect of DevOps is the CI/CD pipeline, which is effective in the production of software.


The CI/CD tenets consist of:

  • The duties of the members are separated
  • Lower risks
  • Looping feedback at every stage
  • Different test conditions
  • Automation uses a variety of tools.

What are CI CD pipelines ? 

The continuous integration/continuous delivery (CI/CD) pipelines is an innovative DevOps workflow with the goal of delivering software on a regular basis with high reliability. DevOps teams may build code, merge it, testing, deliver releases, and distribute changes to the system jointly and in real-time thanks to the iterative, as opposed to linear, process.

The use of robotics to guarantee code quality is an important component of the CI/CD workflow. Unit testing is used to deploy code changes to various environments, deliver applications to the manufacturing environment, and uncover dependency and other issues earlier as the software changes move through the pipeline. The automation's task in this situation is to provide quality control, evaluating factors like performance, API usage, and security. 

This guarantees that the recent changes by every team member are thoroughly incorporated and work as intended.

Development teams can increase quality, productivity, and other DevOps KPIs by automating some steps of the CI/CD process.

CI/CD Tools 

The crucial CI/CD tools are listed below:

1. Jenkins

An automated Continuous Integration procedure can be achieved with the aid of Jenkins, an accessible Continuous Integration server. Jenkins is completely written in Java and is free. Almost 300k installations of Jenkins are present worldwide, and that number is increasing daily.


  • Throughout the day, Jenkin will construct and test code frequently.
  • Mechanized build and testing process, which reduces problems and saves time.
  • Every time a build and test are successful, the code is released.
  • The pace of development is quick.

2. Bamboo

Bamboo is a formed build server that manages releases, testing, and automatic builds all in one location. It integrates perfectly with Bitbucket and the JIRA software.


  • Conduct batch tests in parallel
  • The installation of Bamboo is rather easy.
  • Developers and QA can publish to their environments thanks to a feature called per-environment rights.
  • Git workflows and branching are built-in. The branches are merged automatically.

3. CircleCi

CircleCi is a versatile CI solution that works in any setting, such a Python API server, Docker cluster, or cross-platform mobile app. The application's quality is increased and bugs are decreased thanks to this technology.


  • Enables selection Create an environment
  • Includes C++, JavaScript, NET, PHP, Python, and Ruby among the many languages it supports.
  • You can create a unique environment with support for Docker.
  • Every time a relatively new build is triggered, any queued or ongoing builds should be automatically cancelled.

4. Docker 

A containerization tool called Docker is used to build, distribute, and operate applications in containers. It is a deployment tool that is frequently used in CI/CD operations. An application's parts and subparts, including its libraries and other dependencies, are packed. It travels in the container as a single unit.

Docker allows developers to focus on writing code instead of worrying about the platform it will run on. Companies may also get a jump start by incorporating one of the many programmes already designed to run inside a Docker container into their own.

Leaving Remark 

Thus, The cornerstone of DevOps, CI/CD builds a system capable of producing high-quality software in less time. 

Each stage of CI/CD pipeline is aided by a number of tools and a response system that activates when a bug in the recent version is found. The source code can go back to earlier versions with the help of version control technologies. Popular organisations like Amazon, Netflix, Etsy, Target, and many others employ the automated CI/CD method as it can generate speedier updates.
