What is the difference between Continuous Integration (CI), Continuous Delivery (CD), and Continuous Deployment?
❓ Interview Prompt: Compare Continuous Integration (CI), Continuous Delivery (CD), and Continuous Deployment pipelines, automated testing, and release automation.
Clarifying CI/CD pipeline automation stages:
1
Continuous Integration (CI): Developers merge code into the main branch frequently. Every commit triggers automated builds and unit test suites to detect integration bugs immediately.
2
Continuous Delivery (CD): Automatically packages software and deploys artifacts to staging environments, making releases ready for automated or one-click manual production deployment.
3
Continuous Deployment (CD): Takes automation a step further: every change that passes the automated test suite is deployed directly to production automatically without human intervention!
Code Implementation Example
yaml
# GitHub Actions CI Workflow Pipeline
name: CI Pipeline
on: [push]
jobs:
build-and-test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- run: npm ci
- run: npm test💡Configuring an automated GitHub Actions CI build and test pipeline.
🎯 Interview Key Takeaway
CI automates code integration and testing; Continuous Delivery prepares releases; Continuous Deployment deploys passing code to production automatically.
