Three-zone network topology with Internet, DMZ, and Internal segments separated by firewalls and boundary controls. Traffic flows from Internet through DMZ Switch Tier 1 to LTM Load Balancer and DMZ Firewall, then via Boundary Firewall to Internal Network where Internal Firewall Tier 1 gates access to load balancers and DNS clusters. This architecture enforces defense-in-depth by isolating public-facing services in the DMZ while protecting internal resources behind multiple firewall boundaries. Network architects can fork this diagram to customize firewall rules, add redundancy, or adapt zone configurations for specific compliance requirements. The design supports both static and dynamic DNS resolution with dedicated clusters in the internal zone.
