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
