Understanding Fuuz Green/Blue Architecture

Enterprise Structure

Fuuz Enterprise
├── Production Tenant (Blue Environment)
├── Staging Tenant (Green Environment)  
├── Integration Tenant (Equipment Connections)
├── Development Tenant (Build Environment)
└── QA Tenant (Testing Environment)

Key Components

• 🔵 Blue Environment: Current production application serving live users
• 🟢 Green Environment: New application version deployed for testing and validation
• ⚫ Integration Tenant: Dedicated tenant for equipment connections that can buffer data during transitions
• 📋 Package: Versioned collection of application components (models, screens, flows, scripts, queries, integrations, data)

Step-by-Step Green/Blue Deployment Process

Phase 1: Package Creation and Preparation

1.1 Create Your Deployment Package

Navigation: Package Management → Create New Package

Package Configuration Options:

• Full Application Package: Include all models, screens, flows, scripts, queries, and integrations
• Partial Package: Select specific components for targeted updates or patches
• Data Inclusion: Add reference data, configuration data, or migration data as needed

Best Practices:

• Use semantic versioning (e.g., v2.1.0) for major releases
• Create patch packages (e.g., v2.1.1) for bug fixes and minor updates
• Include comprehensive descriptions and change logs
• Tag packages with environment targets (DEV, QA, PROD)

1.2 Run Comprehensive Validation

Fuuz automatically performs intelligent linting that checks for:

• Missing Dependencies: Ensures all referenced models, flows, and scripts are included
• Data Model Conflicts: Validates schema compatibility and relationship integrity
• Integration Requirements: Verifies all external system connections are properly configured
• Screen Dependencies: Confirms all required flows and data sources are available
• Access Control: Validates user permissions and security configurations

Validation Results:

• ✅ Green: Package ready for deployment
• ⚠️ Yellow: Warnings that should be reviewed but don't block deployment
• ❌ Red: Critical issues that must be resolved before deployment

Phase 2: Green Environment Deployment

2.1 Choose Your Deployment Strategy

Option A: New Tenant Deployment (Recommended for Major Updates)

Benefits:
✅ Zero risk to production environment
✅ Complete isolation for testing
✅ Instant rollback capability
✅ Parallel operation with Blue environment

Option B: In-Place Tenant Upgrade (Suitable for Minor Patches)

Benefits:
✅ Simpler data management
✅ No user migration required
✅ Resource efficient
⚠️ Requires more careful planning

2.2 Deploy to Green Environment

Navigation: Package Management → Deploy Package → Select Target Tenant

Deployment Process:

1. Select your validated package
2. Choose target Green tenant (or create new tenant)
3. Configure deployment options:
   • Data migration strategy
   • Integration endpoints
   • User access controls
4. Execute deployment
5. Monitor deployment progress and validation results

Phase 3: Green Environment Testing and Validation

3.1 Equipment Integration Testing

Real-Time Systems Integration:

• Equipment integrations continue running in dedicated Integration Tenant
• Data buffering ensures no loss during Green environment testing
• Test hardware connections without affecting production operations
• Validate sensor data flow, PLC communications, and SCADA integrations

3.2 User Acceptance Testing (UAT)

Controlled User Access:

• Grant specific users/groups access to Green environment
• Maintain Blue environment for production operations
• Conduct parallel testing with real operational data
• Validate business processes and workflows

3.3 Performance and Load Testing

Green Environment Validation:

• Test with production-like data volumes
• Validate response times and system performance
• Confirm integration stability under load
• Test disaster recovery and failover scenarios

Phase 4: Production Cutover

4.1 Plan Your Cutover Strategy

Instant Cutover (Big Bang Approach):

• Switch all users from Blue to Green simultaneously
• Best for: Major releases with significant changes
• Timing: During maintenance windows or low-usage periods

Gradual Migration (Rolling Cutover):

• Migrate users/groups incrementally from Blue to Green
• Best for: Large user bases or risk-averse organizations
• Control: Granular user access management

Canary Release (Subset Testing):

• Migrate small percentage of users first
• Monitor performance and gather feedback
• Gradually increase Green environment usage

4.2 Execute the Cutover

Navigation: User Management → Tenant Access → Modify User Assignments

Cutover Process:

1. Final Green Validation: Confirm all tests passed and systems are ready
2. Data Synchronization: Execute any final data migration flows
3. User Migration: Transfer user access from Blue to Green tenant
4. Equipment Redirect: Point Integration Tenant to Green environment
5. Monitor Transition: Watch system performance and user feedback

4.3 Post-Cutover Validation

• System Performance: Monitor response times and throughput
• Integration Health: Confirm all equipment connections are stable
• User Experience: Gather feedback and monitor support requests
• Data Integrity: Validate data consistency and accuracy

Phase 5: Cleanup and Optimization

5.1 Blue Environment Management

Immediate Actions:

• Maintain Blue environment as rollback option (recommended 24-48 hours)
• Monitor Green environment stability
• Document lessons learned and issues encountered

Long-term Options:

• Decommission Blue: Remove Blue tenant once Green is proven stable
• Repurpose Blue: Use as new Green environment for next release cycle
• Archive Blue: Maintain for compliance or audit requirements

5.2 Integration Tenant Optimization

• Clean up temporary data buffers
• Optimize connection configurations for new Green environment
• Update monitoring and alerting configurations

Rollback Procedures and Risk Mitigation

Instant Rollback (Separate Tenants)

Time to Rollback: < 5 minutes

Process:

1. Identify issue requiring rollback
2. Switch user access back to Blue tenant
3. Redirect equipment integrations to Blue environment
4. Monitor system stability
5. Investigate Green environment issues

Considerations:

• Data Created in Green: May be lost unless migration flows are established
• User Communication: Notify users of temporary rollback
• Issue Resolution: Fix Green environment problems before next attempt

Gradual Rollback (In-Place Updates)

Time to Rollback: 5-15 minutes

Process:

1. Deploy previous package version to affected tenant
2. Run any required data migration flows
3. Validate system functionality
4. Monitor for stability

Considerations:

• Data Compatibility: Ensure rollback package handles newer data structures
• Integration Impact: May require temporary integration adjustments
• User Impact: Brief disruption during rollback deployment

Partial Rollback Strategies

Component-Level Rollback:

• Roll back individual screens, flows, or models
• Maintain functional components while fixing problematic ones
• Useful for targeted issue resolution

Feature Flag Integration:

• Use Fuuz configuration parameters as feature flags
• Enable/disable specific functionality without full rollback
• Gradual feature enablement and testing
