Enterprise service-oriented architecture integrating Oracle Siebel CRM, SOA Suite, APEX 24.2, and Analytics Server behind a DMZ load balancer for Mauritius government services. Oracle Data Integrator consolidates data across four Oracle DB 26ai instances (CRM, SOA, APEX, DW/ML) while WebLogic clusters provide application tier redundancy. Oracle SOA Suite connects to MU Govt ESB InfoHighway, federating access to 14 government agencies including Civil Status Division, Passport & Immigration, Mauritius Revenue Authority, and digital services (MauPass, MauSign, MoKloud, MAIA, MoWallet). This architecture demonstrates how Oracle middleware enables secure cross-agency data exchange and citizen-facing digital transformation at national scale.
