The Role of CI/CD in DevOps

Continuous Integration Explained

Continuous Integration (CI) is a practice where developers frequently merge their code changes into a shared repository. Each merge triggers an automated build and test process, ensuring that new code integrates smoothly with the existing codebase. This practice helps catch bugs early and improves the overall quality of the software.

Continuous Delivery and Deployment

Continuous Delivery (CD) extends CI by automating the release process, so new code changes can be deployed to production at any time. Continuous Deployment takes it a step further by automatically deploying every change that passes the automated tests. This ensures that software is always in a releasable state, making it easier to deliver updates to users quickly.

How CI/CD Bridges Development and Operations

CI/CD plays a crucial role in bridging the gap between development and operations. By automating the integration, testing, and deployment processes, CI/CD fosters a culture of shared responsibility and collaboration among teams.
