Strangler Fig Orchestrator

Strangler Fig Orchestrator Skill

Orchestrates the strangler fig pattern implementation for gradual migration from legacy to modern systems with traffic routing and cutover management.

Purpose

Enable incremental migration for:

• Traffic routing configuration
• Feature flag management
• Gradual cutover orchestration
• Rollback coordination
• Legacy component sunset

Capabilities

1. Traffic Routing Configuration

• Configure API gateway rules
• Set up routing weights
• Handle header-based routing
• Manage path-based routing

2. Feature Flag Management

• Create feature flags
• Control rollout percentage
• Manage user segments
• Handle A/B testing

3. Gradual Cutover Orchestration

• Plan cutover phases
• Execute incremental shifts
• Monitor health metrics
• Coordinate teams

4. Rollback Coordination

• Define rollback triggers
• Automate rollback
• Preserve state
• Document recovery

5. Progress Tracking

• Track migration progress
• Monitor adoption rates
• Report on status
• Visualize timeline

6. Legacy Component Sunset

• Plan decommissioning
• Verify no traffic
• Archive data
• Clean up resources
