Gov Housing MIS enterprise network topology implements a dual-zone architecture with Internet DMZ and Government Extranet zones, each protected by active-standby firewall pairs, IPS, WAF, and cryptographic gateway layers running Guorui PaaS and XC Resources. Traffic flows through Nginx and OpenResty proxy layers into TongWeb Middleware application servers hosting low-code platforms, housing portals, qualification management, lottery systems, and interface services, with data persistence across Kingbase primary-standby clusters and data warehouses. This design enforces strict perimeter security, cryptographic isolation, and redundancy at every layer—critical for government housing administration systems handling sensitive citizen data and financial transactions. Fork and customize this topology on Diagrams.so to adapt firewall rules, add additional subordinate bureaus, or modify crypto gateway configurations for your jurisdiction. The core interconnection layer uses SDH/MPLS links to securely federate with subordinate bureaus and external institutions while maintaining zero-trust principles.
