Deux Chantiers, Une Liberte

🏰 SCENE 1: LEGACY STACK - "Two Towers, Two Rents"

La Dette Technologique

Deux tours de dependances couteuses : l'AS400/iSeries avec ses licences IBM et le middleware TIBCO/WebMethods avec ses licences annuelles exorbitantes.

AS400/iSeries RPG/COBOL, DB2/400, CL Batch, 5250 screens
ERP Core 20+ ans de regles metier encodees
TIBCO BusinessWorks EAI, messaging, orchestration
WebMethods Integration Server, Trading Networks, EDI
Rente Totale: 1M+/an
⚡ CHANTIER 1: LIBERATION INTEGRATION - Quick Win

Migration TIBCO/WebMethods vers Stack Open Source

Premier chantier a ROI immediat : eliminer les licences d'integration couteuses tout en modernisant l'architecture.

  • Apache Kafka - Event streaming platform, remplace TIBCO EMS
  • Apache Camel - 300+ connecteurs, remplace BusinessWorks
  • Kong/APISIX - API Gateway moderne, remplace WebMethods Gateway
Kafka Topics, consumer groups, exactly-once
Apache Camel EIP patterns, routing, transformation
Kong API Gateway Rate limiting, security, analytics
Economie: -900K/an en licences
🏛 CHANTIER 2: MIGRATION COEUR METIER - A Votre Rythme

Transformation AS400/RPG vers Stack Moderne

Deuxieme chantier, a votre rythme : migrer le coeur metier tout en preservant la souverainete des donnees.

  • Java/Spring Boot - Microservices, REST APIs, containerized
  • PostgreSQL - ACID compliance, zero licensing, enterprise-grade
  • React Frontend - Modern UI replacing 5250 screens
Java/Spring Millions de developpeurs, ecosysteme mature
PostgreSQL JSON support, replication, partitioning
React UI UX moderne, productivite x3
Reduction: -60% TCO
🔬 SCENE 6: TNR - VALIDATION PARALLELE

Double Validation: Core + Integration

Validation en parallele des deux chantiers pour garantir zero regression sur l'ensemble du systeme.

Source Capture AS400 transactions + TIBCO/WM flows
Comparison Engine AI-powered dual-track validation
Target Capture Java services + Kafka/Camel flows

GOAL: ZERO REGRESSION

Functional equivalence certified
