The speed at which your organisation can deliver software directly impacts its competitiveness. Manual build, test, and deployment processes that worked for quarterly releases cannot support the weekly or daily release cadence that modern businesses require. CI/CD (Continuous Integration and Continuous Deployment) automates this pipeline, enabling teams to ship reliable software faster with less risk.
Azure DevOps is Microsoft's comprehensive DevOps platform, providing version control, build automation, test management, artifact management, and release pipelines in a single integrated service. For organisations already invested in the Microsoft ecosystem -- running Azure infrastructure, Microsoft 365, and Entra ID -- Azure DevOps provides the tightest integration and the most natural fit.
According to the 2024 DORA State of DevOps Report, elite-performing teams deploy code 973 times more frequently than low performers, with 6,570 times faster lead times. The foundation of this performance difference is automated CI/CD pipelines.
Key Takeaway
CI/CD is not just about speed. Automated pipelines catch bugs earlier (shifting left), enforce security scanning before deployment, and provide complete audit trails of every change -- critical for Australian organisations subject to compliance requirements.
CI/CD Fundamentals
Continuous Integration (CI) is the practice of automatically building and testing code every time a developer pushes changes. This catches integration issues early, when they are cheapest to fix. Continuous Deployment (CD) extends this by automatically deploying validated code to staging or production environments, reducing the manual handoffs that introduce delays and errors.
A typical CI/CD pipeline includes these stages:
- Source -- Developer pushes code to a Git repository (Azure Repos or GitHub)
- Build -- The pipeline compiles code, resolves dependencies, and creates deployable artifacts
- Test -- Automated unit tests, integration tests, and security scans run against the build
- Stage -- Artifacts are deployed to a staging environment for validation
- Approve -- Manual or automated approval gates control promotion to production
- Deploy -- The validated artifact is deployed to production using a safe deployment strategy
- Monitor -- Post-deployment health checks verify the release is performing as expected
Azure DevOps Pipelines: YAML vs Classic
Azure DevOps supports two pipeline authoring approaches. YAML pipelines (recommended) define the pipeline as code in a YAML file stored alongside your application code. Classic pipelines use a visual editor in the Azure DevOps web interface. YAML pipelines are strongly recommended for production use because they are version-controlled, reviewable in pull requests, and portable across projects.
| Aspect | YAML Pipelines | Classic Pipelines |
|---|---|---|
| Configuration | Code (azure-pipelines.yml) | Visual editor (web UI) |
| Version Control | Yes -- stored in Git with your code | No -- stored in Azure DevOps |
| Pull Request Review | Yes -- pipeline changes reviewed like code | No -- changes made directly in UI |
| Reusability | Templates and extends keywords | Task groups |
| Multi-Stage | Full support (build + deploy in one file) | Separate build and release pipelines |
| Recommended For | All new pipelines | Quick prototyping only |
Security Scanning in Pipelines
A CI/CD pipeline is only as good as its security gates. Modern pipelines integrate security scanning at multiple stages to catch vulnerabilities before they reach production:
- Static Application Security Testing (SAST) -- Analyse source code for security vulnerabilities during the build phase using tools like Microsoft Security DevOps, SonarQube, or Checkmarx
- Software Composition Analysis (SCA) -- Scan third-party dependencies for known vulnerabilities using Dependabot, Snyk, or WhiteSource
- Container Image Scanning -- Scan Docker images for OS-level and application vulnerabilities before pushing to Azure Container Registry
- Infrastructure as Code Scanning -- Validate Terraform and Bicep templates against security best practices using Checkov, tfsec, or Microsoft Defender for Cloud
- Dynamic Application Security Testing (DAST) -- Run automated security tests against the deployed staging environment using OWASP ZAP or Burp Suite
Key Takeaway
Security scanning in CI/CD is not optional for Australian businesses. The Essential 8 framework requires patching applications within 48 hours of critical vulnerability disclosure. Automated dependency scanning in your pipeline ensures you are aware of vulnerabilities the moment they are published.
Deployment Strategies
How code reaches production matters as much as the code itself. Azure DevOps supports several deployment strategies:
Rolling Deployments
Update instances progressively, maintaining availability throughout. Suitable for most web applications and APIs.
Blue-Green Deployments
Maintain two identical environments. Deploy to the inactive environment, validate, then switch traffic. Provides instant rollback by switching back. Ideal for critical applications.
Canary Releases
Route a small percentage of traffic to the new version, monitor metrics, and gradually increase traffic if healthy. Best for high-traffic applications where even brief degradation is costly.
Deployment Gates and Approvals
Azure DevOps provides approval gates that control when deployments proceed between stages. These include manual approvals (requiring sign-off from designated reviewers), automated gates (checking Azure Monitor health, work item status, or external API responses), and scheduled deployment windows (restricting production deployments to approved change windows).
For organisations subject to ISO 27001 or Essential 8 change management requirements, these gates provide the documented evidence that changes were reviewed, approved, and deployed through a governed process.
