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
