Software Centre - 3-Tier Network Architecture
About This Architecture
Three-tier hierarchical network architecture with DMZ perimeter security, redundant core switching, and departmental VLANs serving 100 users across four access layers. Internet traffic flows through a Firewall (192.168.0.1) and WAF into a dual Core Switch fabric (10.0.0.1/10.0.0.2), which distributes to four Distribution Switches and four departmental Access Switches via Cat-6 cabling. A Load Balancer (10.0.2.5) fronts four specialized servers—App, DB, File, and Auth—in the Server Room, with RADIUS authentication and SNMP/Syslog monitoring integrated throughout. This design demonstrates high availability, scalability, and security segmentation essential for mid-sized enterprise networks. Fork and customize this diagram on Diagrams.so to adapt IP schemes, add redundancy, or document your own data center topology.

What does a production 3-tier enterprise network architecture look like with redundancy and security?
A 3-tier network separates Internet-facing DMZ (Firewall, WAF, VPN Gateway) from internal LAN via redundant Core Switches (10.0.0.1/10.0.0.2), which feed Distribution Switches that connect departmental Access Switches and a Server Room. Load Balancer (10.0.2.5) distributes traffic to App, DB, File, and Auth servers; RADIUS and SNMP/Syslog provide authentication and monitoring.
