Agile software development technologies have changed the way the industry works on software development and delivery. Beyond software, project management, in general, has been transformed by agile methodology. The product development lifecycle steps and processes are defined by methods such as CI/CD and DevOps. Let’s explore DevOps Vs CICD and understand them in detail.
What is CI/CD (Continuous Integration/Continuous Delivery)?
Continuous Integration/Continuous Delivery (CI/CD) defines the set of practices and principles to be followed by the development teams to ensure accurate and reliable modifications to the code. Automation tools are employed throughout the software development lifecycle to speed up time-to-release of the products. The iterative approach is helpful to detect and fix bugs earlier in the development process.
Continuous Integration
Continuous Integration (CI) requires a shared core repository. CI practice forces developers to integrate code changes into the repository to enable the detection and fixing of bugs before they become challenging and expensive to resolve. Automated testing is an integral part of CI so that the code changes don’t affect existing functionality. With CI, it is easier for the developers to introduce new software functionalities.
Continuous Delivery
Continuous Delivery (CD) automatically deploys all the code changes to the production once testing is complete. This optimizes the pace at which new features are brought to the market and bug fixes at a lower risk. Code promotion or code freeze is another process that is standardly utilized in CD to verify code quality and enforce code compliance with the automation of scripts and deployment tools.
What is DevOps?
DevOps culture promotes communication and collaboration between the development and operations teams. There must be a shared responsibility for both teams throughout the SDLC. It improves the speed and quality of product and software development. Signing up for DevOps engineer course will qualify professionals to learn and implement these practices in enterprises.
Similar to CI/CD, DevOps also uses automation for testing, deployment, and monitoring. The basic concept of DevOps is the use tools and practices to eliminate errors and repetitiveness in SDLC , while increasing effectiveness and efficiency. Containerization tools are frequently utilized for infrastructure management and configuration management. Similarly, these are helpful in monitoring and logging software performance during production.
Specifically, agile feedback depends on the assessment of outcomes and the subsequent implementation of slight adjustments to enhance the software’s functionality.
With DevOps projects, enterprises can embrace new technologies like cloud computing and artificial intelligence for process improvement. Further, DevOps focuses on security principles and ensures that security practices are implemented throughout the SDLC.
8 Key Differences Between CI/CD and DevOps
The goal of both CI/CD and DevOps is to expedite software development and deliver the software with fewer errors and advanced functionalities. The following table highlights the differences between CI/CD and DevOps:

How is CI/CD Different from DevOps (Differences in Processes and Implementation)?
DevOps incorporates CI/CD automation to improve speed and accuracy. The processes and implementation vary. CI/CD focuses only on code integration and delivery. It focuses on the technical aspects of the automated software delivery pipeline.
On the other hand, the implementation of DevOps requires a massive culture change. The development and operations teams must adopt several practices to collaborate, communicate, and share the responsibility of delivering the software product. While it also leverages various tools for automation, monitoring and continuous improvement for DevOps is crucial.
Also, DevOps inculcates a culture of learning and experimentation, allowing the teams to evolve their agile practices and workflows to maximise optimization. As a result, the integration of technology in containerization, cloud computing, and artificial intelligence is crucial for DevOps’ real-time scenario operations.
What is CI/CD in DevOps? How are They Related to Agile?
Code integration and deployment is an essential component of DevOps. So, CI/CD plays a significant role in implementing agile practices as a part of DevOps. Iterative development and continuous improvement ensure the automation and efficiency necessary to support the rapid growth and deployment cycles that DevOps aims to achieve. By automating the build, test, and deployment processes, CI/CD enables DevOps teams to focus on delivering value to customers faster.
Agile development methodology emphasises iterative development, collaboration, and customer feedback. CI/CD and DevOps align closely with agile principles by promoting continuous improvement, flexibility, and adaptability. With frequent iterations and feedback of CI/CD pipeline and DevOps mechanisms to rapidly deliver and test these iterations, enterprises can implement agile practices.
What is the Difference Between Continuous Integration and Continuous Delivery?
The process of continuous integration encompasses the act of integrating code and then running tests on it. CI is important in early stages to resolve the Integration issues during the development phase. Continuous delivery focuses on automating the process of the delivery of the code for making it ready for release at any time. CD makes it possible to have the software code in a releasable state at all times.
Leveraging CI/CD and DevOps to Drive More Innovation
DevOps training enables key personnel to understand the impact and benefits of the culture change. CI/CD Vs. DevOps creates an environment that fosters innovation and offers the following benefits:
- Accelerated time to market allows businesses to respond to market changes and customer demands.
- Encourages experimentation with frequent deployments and automated testing for new ideas without fear of failure.
- Improved communication and collaboration between development and operations teams pave the way for more innovative solutions.
How do we Implement CI/CD with a DevOps Culture?
The following steps are needed for an organization to implement CI/CD within a DevOps culture:
- Build a Strong Foundation – Development and operations teams must be informed of the new practices, and the organization must prepare for a cultural shift. This requires conscious efforts to foster collaboration and shared responsibility. Cross-functional teams must be built with developers, QA engineers, and operations personnel. Open communication must be encouraged through regular meetings and daily updates.
- Version Control System – The codebase can be optimized with a version control system such as Git. This makes tracking of code easier and allows rollbacks to be done if one wants to. Developers can perform updates to progress to create new code that can be checked into the repository. In case of problems the new changes can be abandoned and instead work with the older versions can be done.
- Automate Testing – Automation testing is an important process in CI/CD and DevOps process. When carrying out unit testing, integration testing, and acceptance testing, testing scripts must be designed. Integrating these scripts into the code repository will allow for automated testing for new code updates. This ensures that new code changes don’t damage the existing software functionality.
- Staging Environment – A replica of a production environment called a staging environment should be developed so that further product testing can be done before production. It allows developers and operators to work together to monitor bugs and fix the issues before the code is delivered to production.
- Automated Deployment – The code that is tested in the staging environment must be automatically deployed to production. This ensures faster and more reliable software releases backed by testing scripts.
- Monitoring and Logging Tools – The organization must invest in quality monitoring and logging tools that can be used throughout the development lifecycle. These tools can also be used to monitor and track process performance so that the DevOps processes can also be optimized.
Testing and Automation in CI/CD and DevOps
Testing is an indispensable part of SDLC, and it is even more crucial in CI/CD and DevOps environments. Automation testing is pivotal to improving the quality and speed of software delivery. The different types of testing that can be automated in organizations with DevOps culture are:
- Unit testing
- Integration testing
- Functional testing
- Performance testing
- Security testing
To benefit from automation testing in the CI/CD pipeline, the automated test scripts must be included early in the development process. This is called shift-left testing. From unit to production, executing continuous testing throughout the pipeline enables organizations to benefit from testing automation.
