+# Modernization Plan for test-alex-1-1
+
+## Application Type
+Java Application
+
+## Selected Modernization Strategy
+- **Migration Approach**: containerize-optimize
+- **Target Platform**: orchestrator
+- **Observability**: ENABLED (Prometheus metrics, health checks, tracing)
+- **Security Scanning**: ENABLED (Trivy vulnerability scanning)
+
+## Discovery Summary
+### Discovery Report
+
+#### Application Overview
+- **Type**: Java-based application
+- **Framework**: Spring Boot
+- **Build Tools**: Maven and Gradle
+- **Primary Purpose**: Likely a web application, as indicated by the presence of REST API endpoints and web-related dependencies.
+
+#### Technology Stack
+- **Language**: Java
+- **Framework**: Spring Boot
+- **Build Tools**: Maven and Gradle
+- **Database**: H2, MySQL, PostgreSQL (based on dependencies)
+- **Caching**: Caffeine, javax.cache (cache-api)
+- ...
+
+## Generated Artifacts
+1. **Dockerfile**: Optimized with health checks and metrics endpoints
+2. **score.yaml**: Platform intent with service ports and DNS resource
+3. **CI Workflow**: Automated build/push to ACR with Trivy security scanning
+
+## Next Steps
+1. Review and customize generated artifacts
+2. Test container build and run
+3. Deploy to development environment using score.yaml
+4. Validate application functionality
+5. Promote to staging/production via Humanitec
+
+## Migration Strategy Details
+
+### Containerize Optimize
+Add cloud-native patterns: health checks, metrics, optimized base images.
+
+### Platform: orchestrator
+score.yaml optimized for Azure Container Apps with managed scaling and Azure-specific configuration.
