CI/CD and ERP: Finding the Balance#
Traditional ERP deployment cycles measured in months don't align with modern CI/CD practices that deploy multiple times per day. But ERP systems can benefit from automated deployment pipelines—if designed appropriately.
The reality: ERP CI/CD is different from typical application CI/CD. The stakes are higher, the testing requirements are more extensive, and the deployment windows are more constrained.

What CI/CD Means for ERP#
Continuous Integration#
For ERP development: - Code changes automatically built and tested - Configuration changes validated - Customisations checked against standards - Integration tests run automatically
Continuous Delivery#
For ERP deployment: - Changes automatically prepared for deployment - Deployment packages created consistently - Environments kept in sync - Rollback capability maintained
The ERP Difference#
Unlike typical applications: - Changes often require business validation - Deployment windows are limited - Testing is more extensive - Stakeholder approval is required - Rollback is complex

Pipeline Design for ERP#
Stage 1: Source Control#
All changes in version control: - Custom code (ABAP, Java, .NET) - Configuration exports - Integration specifications - Documentation
Stage 2: Build#
Automated build process: - Compile custom code - Package configuration - Generate deployment artefacts - Create documentation
Stage 3: Test#
Automated testing: - Unit tests for custom code - Integration tests - Regression tests - Performance tests
Stage 4: Approval#
Human approval gates: - Technical review - Business validation - Change advisory board - Deployment scheduling
Stage 5: Deploy#
Automated deployment: - Environment preparation - Artefact deployment - Post-deployment verification - Monitoring activation
---
Testing Strategies#
Unit Testing#
Test individual components: - Custom code functions - Business logic - Data transformations
Integration Testing#
Test component interactions: - Integration with external systems - Database operations - API interactions
Regression Testing#
Ensure existing functionality works: - Critical business processes - High-volume transactions - Integration points
Performance Testing#
Validate performance: - Load testing - Stress testing - Endurance testing

Deployment Patterns#
Blue-Green Deployment#
Maintain two identical environments: - Deploy to inactive environment - Test thoroughly - Switch traffic - Rollback if needed
ERP considerations: - Database migration complexity - State management during switch - Cost of duplicate infrastructure
Canary Deployment#
Gradually shift traffic: - Deploy to subset of users - Monitor for issues - Gradually expand - Rollback if problems
ERP considerations: - User identification and routing - Data consistency - Feature flags implementation
Rolling Deployment#
Update instances gradually: - Update one instance at a time - Verify each update - Continue if successful - Rollback if failures
ERP considerations: - Session handling - Database compatibility - Backward compatibility

ANZ-Specific Considerations#
Time Zone Planning#
Deployment timing for ANZ: - Evening deployments (outside business hours) - Weekend maintenance windows - Holiday period changes - Global operations coordination
Communication#
Stakeholder communication: - Advance notice of changes - Status updates during deployment - Post-deployment confirmation - Issue notification
Regulatory#
Compliance considerations: - Change documentation - Approval records - Audit trails - Regulatory notification

Pipeline Implementation#
GitHub Actions Example#
`yaml
name: ERP Deployment
on: push: branches: [main]
jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Build run: ./build.sh - name: Test run: ./test.sh
deploy-dev: needs: build runs-on: ubuntu-latest environment: development steps: - name: Deploy to Development run: ./deploy.sh dev
deploy-prod:
needs: deploy-dev
runs-on: ubuntu-latest
environment: production
steps:
- name: Deploy to Production
run: ./deploy.sh prod
`
Azure DevOps Example#
`yaml
trigger:
- main
stages: - stage: Build jobs: - job: Build steps: - script: ./build.sh - stage: DeployDev jobs: - deployment: DeployDev environment: development strategy: runOnce: deploy: steps: - script: ./deploy.sh dev
- stage: DeployProd
---
Monday Morning Action Plan#
- Assess Current Deployment Process: Document how changes currently move from development to production.
- Identify Automation Opportunities: Which steps could be automated?
- Start with Development: Implement CI/CD for development environment first.
- Add Testing: Build automated testing into the pipeline.
- Plan for Production: Design the production deployment process with appropriate safeguards.

Conclusion: CI/CD for ERP Requires Adaptation#
CI/CD principles apply to ERP, but the implementation differs from typical application development. The key is: - Automate what can be automated - Keep human approval where needed - Test thoroughly - Deploy during appropriate windows - Maintain rollback capability
