Design Philosophy¶
Muneris Mobile Ordering's architectural decisions reflect a deliberate focus on solving specific restaurant industry problems through targeted technical choices. The platform's design philosophy emerges from documented business constraints, operational requirements, and strategic positioning decisions that prioritize restaurant operational success over technical complexity.
Core Design Principles¶
Oracle Simphony Specialization¶
Design Decision: Build exclusively for Oracle Simphony POS systems rather than attempting broad POS compatibility.
Rationale: The solution emphasizes deep Oracle Simphony integration as a core differentiator. This specialization enables:
- Direct STS Integration: Direct connection to Simphony Transaction Service for real-time order processing
- Advanced Menu Synchronization: Full bidirectional menu and pricing synchronization
- Native Workflow Integration: Orders flow seamlessly into existing operational patterns
- Advanced POS Features: Simphony-specific capabilities like condiments and combo meals
Business Constraint Influence: Rather than developing lowest-common-denominator POS integration, the platform achieves restaurant operational excellence through Oracle Simphony depth.
Property-Based Multi-Tenancy Architecture¶
Design Decision: Structure the entire system around restaurant properties as the fundamental organizational unit.
Implementation: The system is structured around the following principles:
- Company-Property Hierarchy: Companies contain multiple properties (restaurant locations)
- Property-Scoped Configuration: STS, Payment providers and operational settings per property
- Isolated Property Operations: Each property operates independently with its own configuration
- Property-Level Security: Access controls and data isolation at the property level
Operational Alignment: This design reflects the reality that restaurant chains need location-specific configurations while maintaining corporate oversight and standardization capabilities.
Regional Redundancy from Day One¶
Design Decision: Deploy complete infrastructure across three regions from initial implementation rather than starting with a single region.
Architecture: The platform implements:
- Three-Region European Deployment: Complete infrastructure across Germany, France, and Ireland
- Complete Regional Independence: Each region contains full API stack and database
- Traffic Manager Routing: Automatic DNS-based routing to healthy regions
- Regional Data Sovereignty: Customer data remains within specified geographic boundaries
Strategic Reasoning: This approach addresses data sovereignty requirements and provides operational resilience from the beginning, avoiding the complexity of later regional expansion.
Passwordless Authentication Strategy¶
Design Decision: Implement JWT-based passwordless authentication using email verification rather than traditional username/password systems.
Benefits: The authentication flow provides:
- 14-Day JWT Tokens: Long-lived tokens enable bookmark-friendly access patterns
- Email-Based Verification: Security through email account control rather than password management
- Automatic Token Renewal: Seamless token refresh when expired tokens are detected
- Company-Scoped Access: Tokens provide access only to specific company data
User Experience Philosophy: This approach reduces password management burden while maintaining security through email account control, recognizing that restaurant administrators value operational simplicity.
Deployment Architecture Philosophy¶
Design Decision: Implement comprehensive cloud-native deployment from initial release rather than evolving from on-premises solutions.
Platform Choices:
- Admin Portal: Blazor WebAssembly (.NET 8.0) hosted on Azure App Service at admin.muneris.app
- API Backend: Azure Functions with serverless scaling and regional deployment
- Database: Azure Table Storage with regional independence and automated backups
- Secret Management: Azure Key Vault with automated 14-day secret rotation
- Traffic Coordination: Azure Traffic Manager for DNS-based regional routing
Operational Philosophy: Cloud-native architecture eliminates restaurant IT infrastructure requirements while providing enterprise-grade capabilities through managed Azure services.
