Basic Config things to keep in mind as best Practise for Cognos 10- Internet

[bp3965]

All-

I am very new and I would like to know any best practise for Cognos 10 with apache ouside the fire wall. Example one would be to have Gateway piece installed on Web Server outside the firewall. Second I am looking if I need have web logic as a middleware product in that case if I have mutiple apps then should I have to use LTM/LB loab Balencer in between WebServer and middleware product since each dispatcher would concor to each app server. Whould load balencing would be needed as I will not be usin plugin? I have only one WebServer outside firewall and one App Server inside firwall.
