CI/CD
Continuous Integration / Continuous Delivery
Continuous Integration and Continuous Delivery/Deployment -- automated practices that enable frequent, reliable code changes through automated building, testing, and deployment pipelines.
In-Depth Explanation
CI/CD combines Continuous Integration and Continuous Delivery (or Continuous Deployment) to automate the software development lifecycle. It enables teams to deliver code changes more frequently and reliably through automation.
Continuous Integration (CI):
- Developers merge code changes to a shared repository frequently (multiple times daily)
- Each merge triggers automated builds and tests
- Problems are detected and fixed quickly
- Reduces integration conflicts and "merge hell"
Continuous Delivery (CD):
- Code that passes CI is automatically prepared for release
- Deployment to production requires manual approval
- Ensures code is always in a deployable state
- Reduces deployment risk through small, frequent releases
Continuous Deployment:
- Code that passes all automated tests is automatically deployed to production
- No manual approval needed
- Requires high confidence in automated testing
- Enables multiple deployments per day
CI/CD pipeline stages:
- Source: Code committed to version control (Git)
- Build: Application compiled/built
- Test: Automated tests run (unit, integration, end-to-end)
- Stage: Deploy to staging environment for verification
- Deploy: Release to production
- Monitor: Track application health post-deployment
CI/CD tools:
- GitHub Actions: Integrated with GitHub repositories
- GitLab CI/CD: Built into GitLab platform
- Jenkins: Open-source, highly customisable
- CircleCI: Cloud-native CI/CD
- AWS CodePipeline: AWS-native CI/CD
- Vercel/Netlify: Automated deployment for web applications
Business Context
CI/CD reduces deployment risk by 50-80% and enables teams to ship improvements faster, with high-performing teams deploying 200x more frequently than low performers while having 24x faster recovery from failures.
How Clever Ops Uses This
Clever Ops sets up CI/CD pipelines for Australian businesses, enabling their development teams to ship changes confidently and frequently. We configure automated testing, staging environments, and deployment workflows that reduce the risk of deploying broken code while accelerating the delivery of new features and improvements.
Example Use Case
"A SaaS company implements GitHub Actions CI/CD, reducing their deployment process from a risky 4-hour manual procedure done monthly to an automated 15-minute pipeline run multiple times per week."
