About This Architecture

Enterprise-grade SAP ERP network architecture with Oracle Database backend demonstrates defense-in-depth security across five VLANs. Traffic flows from WAN through DMZ components—SAProuter, WAF, outer firewall, reverse proxy, and VPN gateway—into a core layer managed by VLAN-trunked switches and inner firewall. VLAN 10 hosts SAP Central Instance with dispatcher, Oracle DB Server on port 1521, and multiple application servers; VLAN 20 isolates Solution Manager, internal SAProuter, monitoring, and log servers; VLAN 30 and 50 provide dedicated interface zones for external system integrations; VLAN 40 serves client access via SAP GUI and web clients. This template solves the challenge of securing SAP landscapes while maintaining connectivity to SAP Support Network and third-party systems. Fork this diagram on Diagrams.so to customize IP schemes, add your interface protocols, or export as .drawio for Visio-compatible documentation.

How do I design a secure SAP ERP network architecture with Oracle Database and multiple VLANs for production environments?

Implement a five-VLAN topology: VLAN 10 for SAP Central Instance and Oracle DB Server (port 1521), VLAN 20 for Solution Manager and monitoring, VLAN 30/50 for interface systems, VLAN 40 for client access. Place SAProuter, WAF, and dual firewalls in DMZ to control WAN and SAP Support Network traffic. This diagram template provides the complete network layer design.
