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/CD is a solution to the problems integrating new code can cause for development and operations teams.
Specifically, CI/CD introduces ongoing automation and continuous monitoring throughout the lifecycle of apps, from integration and testing phases to delivery and deployment.
Jenkins is an open-source Continuous Integration server written in Java for orchestrating a chain of actions to achieve the Continuous Integration process in an automated fashion. Jenkins supports the complete development life cycle of software from building, testing, documenting the software, deploying, and other stages of the software development life cycle.
Jenkins is a widely used application around the world that has around 300k installations and growing day by day. By using Jenkins, software companies can accelerate their software development process, as Jenkins can automate build and test at a rapid rate.
GitHub Actions makes it easy to automate all your software workflows, now with world-class CI/CD. Build, test, and deploy your code right from GitHub. Make code reviews, branch management, and issue triaging work the way you want.
Automate, customize, and execute your software development workflows right in your repository with GitHub Actions. You can discover, create, and share actions to perform any job you’d like, including CI/CD, and combine actions in a completely customized workflow.
CircleCI is a modern continuous integration and continuous delivery (CI/CD) platform. The CircleCI Enterprise solution is installable inside your private cloud or data center and is free to try for a limited time. CircleCI automates the build, test, and deployment of software.
CircleCI provides enterprise-class support and services, with the flexibility of a startup. We work where you work: Linux, macOS, Android, and Windows – SaaS or behind your firewall.
Azure Pipelines automatically builds and tests code projects to make them available to others. It works with just about any language or project type. Azure Pipelines combines continuous integration (CI) and continuous delivery (CD) to constantly and consistently test and build your code and ship it to any target.
The Azure CI/CD pipeline simplifies continuous integration and continuous delivery (CI/CD) in the application development process. Apart from continuous integration and continuous deployment with Azure DevOps, these pipelines are used to construct build-deploy-test workflows used mainly in continuous testing (CT)
