Continuous Delivery Pipelines

# Continuous Delivery Pipelines

Automate everything from commit to production. Ship faster with confidence.

## Pipeline Stages

**Build**

Compile, package, create artifacts. Fast feedback on syntax errors.

**Test**

Unit, integration, security scans. Gate bad code early.

**Deploy to Staging**

Identical to production. Run E2E tests, load tests.

**Deploy to Production**

Automated or one-click. Feature flags for safety.

## Deployment Strategies

**Blue-Green**

Two identical environments. Switch traffic instantly. Easy rollback.

**Canary**

Gradual rollout. 5% → 25% → 50% → 100%. Monitor metrics between stages.

**Rolling**

Update instances gradually. No downtime.

## Best Practices

- Pipeline as code

- Immutable artifacts

- Automated testing at every stage

- Automatic rollback on failure

- Comprehensive monitoring

## Tools

Jenkins, GitLab CI, GitHub Actions, CircleCI, ArgoCD

Continuous delivery is continuous improvement.
