CI/CD solutions and the DevOps approach

Published on 9 February 2023

CI/CD (Continuous Integration/Continuous Deployment) is one of the key principles of the DevOps approach. It helps to accelerate, make reliable and secure applications and deployments. DevOps is a collaborative and corporate culture approach that aims to improve communication and collaboration between development and operations teams.

And in practice, what is CI/CD?

The objective of DevOps is to improve the application lifecycle by using tools and practices that promote automation and collaboration. CI/CD tools automate the process of development, testing, and deployment.. Monitoring and supervision tools allow for the observation of applications and platforms in production.

CI/CD is a software development practice that aims to Integrate and deploy changes frequently in a project. Using CI/CD, teams can continuously test and quickly deploy new versions. CI/CD particularly allows for the industrialisation of data platforms and the automation and streamlining of the development, testing, and deployment process for these platforms.

Using CI/CD, development teams can integrate their work on a continuous basisThey can submit their source code changes at any time. These changes are then automatically verified and tested, which ensures that the code remains functional, of high quality, and meets certain security requirements. Furthermore, CI/CD allows for the rapid deployment of new versions, which is crucial for clients who rely on constant platform availability and quick responses to changing needs.

CI/CD is important in DevOps because it enables faster and more reliable software delivery. Continuous Integration (CI) involves frequent merging of code changes into a shared repository, followed by automated builds and tests. Continuous Delivery (CD) extends this by automating the release of code to production. This practice helps to identify and fix bugs early, reduce integration issues, and accelerate the release cycle, which are core principles of DevOps.

Thanks to CI/CD, development teams test more effectively and in real time. This allows errors to be detected and corrected quickly and proactively, thereby reducing the risk of failure. Furthermore, CI/CD allows for to precisely follow the changes made to the code and to know exactly when and how each change was deployed. CI/CD is an asset for development teams in terms of collaboration and project management. By integrating changes continuously, developers can work more efficiently and avoid code conflicts.

At JEMS, Security is a crucial aspect of CI/CD. By integrating and frequently testing changes, it is possible to quickly detect and correct security vulnerabilities before they are exploited. Furthermore, by using vulnerability detection and penetration testing tools within the CI/CD process, it is possible to ensure that code changes do not compromise application security.

CI/CD is therefore fundamental for industrialising data platforms. It allows for the automation and streamlining of the development, testing, and deployment process, ensuring high code quality and security, as well as constant availability. It also improves collaboration and project management, facilitating teamwork and collaboration, and enabling a DevOps approach.

Quelles sont les solutions CI/CD disponibles ?

Here are the most common CI/CD solutions implemented by JEMS during project completion:

Jenkins is a popular open-source CI/CD solution. It allows automating development tasks, such as compiling code, testing, and deployment. It also offers numerous plugins to extend its functionalities. One of the advantages of Jenkins is that it is free and easy to use, but it can be complex to configure and maintain.
GitLab CI is a CI/CD solution integrated into the GitLab version control software. It allows for the automation of development tasks and offers seamless integration with the rest of GitLab. One of the advantages of GitLab CI is that it is easy to use and offers seamless integration with GitLab.
Azure DevOps is a project management and CI/CD solution from Microsoft. It offers a wide range of functions for project management, software development and deployment. One of the advantages of Azure DevOps is that it offers great flexibility and a wide range of features.
GitHub Actions is a CI/CD solution integrated with GitHub that allows the automation of development tasks. It is particularly useful for open-source projects hosted on GitHub. One of the advantages of GitHub Actions is that it is easy to use and offers seamless integration with GitHub.
Harness is an intelligent CI/CD solution aimed at simplifying the development, testing, and deployment process. It offers an intuitive interface and easy integration with numerous tools and systems. It provides pre-built modules for tools like Kubernetes or Terraform, which aids the lifecycle in these environments. Thanks to its AI, Harness can monitor the application in real-time, allowing for the detection of problems and rapid response. In particular, it can automate rollbacks in the event of issues during or after a deployment.

Il y a également de numerous alternatives that we implement in projects carried out by JEMS, such as Bitbucket, CircleCI, Travis, TeamCity or the solutions integrated with each cloud provider. Numerous CI/CD solutions are available on the market, each with its own advantages and disadvantages. It is important to choose the solution that suits the need, project and teams best.
