They are each paired with one data center.(For this case study, we will not discuss the additional single Performance and Test module,also located in one of the collocation facilities. It is similar in design.)Inside each collocation facility, VLANs 10, 20, and 30 respectively are the web server,application server, and DB server VLANs. The site runs IBM WebSphere using IBM servers.All traffic enters the web complex through a pair of Brand X firewalls. The paired CSS devicesroute between the firewall VLAN and the “internal” VLANs 10, 20, and 30.
