Project in Active Development & Prototyping
The IT Service Catalogue & Enterprise Topology platform is currently under active architectural prototyping and development. Topological dependency models, blast radius graph traversal algorithms, and SLA governance matrices are actively being iterated.
IT Service Registry & Enterprise Topology
A 4-layer enterprise cartography and automated blast-radius engine providing holistic visibility, bidirectional dependency mapping, and rigorous SLA governance across modern public-sector and enterprise IT estates.
The Challenge & Problem Space
Taming Hidden IT Dependencies & Cascading Outages
In large organizations and public-sector IT departments, services evolve organically across decades. Business services (payroll, public registry, employment assistance) depend on dozens of microservices, third-party APIs, database clusters, SAN storage volumes, and physical networking switches.
When a database server experiences high latency or an infrastructure switch fails, IT operations teams often struggle to determine which citizen or business services are degraded. Conversely, when maintenance is scheduled, understanding the exact blast radius of the disruption requires tedious manual investigation across disparate spreadsheets.
The Catalogue de Services IT & Topologie d'Entreprise was conceived to solve this with a single pane of glass: an interactive, normalized topological cartography linking high-level business capabilities directly to physical infrastructure with instant blast radius simulation.
Architectural Framework
The 4-Layer Enterprise Model
The platform organizes all IT components into four strictly typed, interconnected tiers, enabling both top-down and bottom-up dependency analysis:
Couche 4
Business Scope
Services Métier (Business Services)
High-level operational services delivered to citizens, civil servants, and business partners. Governed by explicit business SLAs, operational hours, and mission-critical tier ratings.
Portail Candidats & Emploi
Gestion des Allocations
Comptabilité & Facturation Publique
Registre Social Cantonal
Couche 3
Application Scope
Services Applicatifs (Application Services)
Software applications, microservices, backend APIs, and portals that execute the business workflows. Includes frontend web clients, workflow orchestration engines, and authentication gateways.
API Gateway / Envoy
Moteur de Workflow BPMN
Service de Génération Documentaire
Keycloak SSO / OIDC
Couche 2
Platform Scope
Plateforme & Données (Platform & Data Services)
Data persistence, message queuing, caching, and runtime environments supporting application services. Configured with strict RPO (Recovery Point) and RTO (Recovery Time) parameters.
Cluster PostgreSQL HA (Patroni)
Redis Cache Cluster
RabbitMQ Message Broker
MinIO S3 Object Storage
Couche 1
Infrastructure Scope
Infrastructure & Réseau (Infrastructure & Networking)
The physical and virtual foundations: virtualization hypervisors, SAN/NAS storage arrays, network switches, VLAN segments, firewalls, and data center facilities.
