In today's fast-paced development world, speed and reliability are paramount. A Continuous Integration and Continuous Delivery (CI/CD) pipeline automates the path from code commit to production deployment. This infographic explores the typical CI/CD process orchestrated by Jenkins, the leading open-source automation server that helps teams build, test, and deploy software faster and more reliably.
A Legacy of Automation Excellence
Jenkins has a rich history of empowering development teams, evolving from its origins as Hudson in 2007 to become one of the most used tools for CI/CD today. It has been recognized with prestigious industry awards for its impact and utility.
Born as Hudson
The project that would become Jenkins began its journey, laying the groundwork for modern CI.

Continues to be one of the most widely adopted tools for continuous integration and delivery.
What is Jenkins? Your CI/CD Companion
Jenkins is a free, open-source automation server that simplifies the complex world of software development. It's the go-to tool for Continuous Integration (CI) and Continuous Delivery (CD), helping teams build, test, and deploy code automatically. By catching issues early and streamlining releases, Jenkins empowers developers to deliver high-quality software faster.
Saves Time
Automates repetitive tasks, freeing up developers for more creative work.
Catches Bugs Early
Integrates testing throughout the development cycle, reducing defect costs.
Frequent Updates
Enables rapid and consistent software delivery to users.
How Jenkins Automates Your Workflow
Jenkins orchestrates the entire software delivery pipeline. From code changes to deployment, it automates every step, ensuring a smooth and efficient process. This diagram illustrates the typical flow.
What is the Jenkins Mailer Plugin?
The Jenkins Mailer plugin is an essential tool that provides automated, real-time feedback directly to your inbox. Instead of manually checking build statuses, it instantly notifies your team about critical events in your CI/CD pipeline. This proactive communication ensures everyone is informed, enabling faster reactions to issues and a more efficient development workflow.
How It Works: The Notification Logic
The plugin follows a clear, conditional logic. It monitors the build process and, upon completion, triggers specific email notifications based on the outcome. This flowchart visualizes the decision-making process.
Build Fails
Build Unstable
Success After Fail
Unstable After Success
Anatomy of an Alert
Build Fails
The most critical alert. Sent immediately when a build cannot be completed, letting you know "something broke" and requires urgent attention.
Build is Unstable
A warning that the build succeeded, but some tests failed or other issues were detected. It's a heads-up that "something's off."
Build Succeeds After a Failure
The good news email. Confirms that a previously failing build is now stable, letting the team know "the problem is fixed."
Build Becomes Unstable After Success
A "regression alert." This important email notifies you when a previously stable build has become unstable, indicating a recent change introduced a new problem.
🔑 Credentials Plugin
The Credentials plugin lets Jenkins securely store and manage login details for use across different plugins and jobs.
📊 External Job Monitoring
Jenkins can monitor and track the results of jobs run outside its system, providing a centralized view of all automation tasks.
🖥️ SSH Agents Plugin
The SSH Agent plugin lets Jenkins connect to and run agents on Linux/Unix machines via SSH, making remote builds easy to manage and integrate.
📄 Javadoc Plugin
The Javadoc plugin lets you publish Java documentation automatically after each build, making it easy to manage and share up-to-date API documentation.
⚡ Shell Scripts
Jenkins allows you to schedule and run shell scripts directly from its interface—no command line needed, enabling flexible custom automation steps.
Robust Security for Your Pipelines
Security is paramount in any automation tool. Jenkins provides essential features to protect your CI/CD pipelines, ensuring that your code and infrastructure remain safe from unauthorized access and malicious threats.
