Hybrid intranet-internet system integration topology with NGINX reverse proxy routing internet users to penetration and integrated systems deployed across both zones. Internet servers and intranet servers run parallel penetration-style and integrated-style systems, with menu integration enabling cross-system access and interface data exchange. All systems converge on a shared intranet database with role-based database accounts for penetration and integrated system users. Budget management servers provide additional integrated system functionality, while internal users access intranet-deployed systems directly.
