Network

Here are some questions to help you understand your network requirements:

• Do you want to obfuscate internal network information?

• Do you want to provide redundancy of network services?

• Do you want to limit available data on access layer hosts?

• Do you want to simplify end-user settings, for example, have end users enter a single mail host that does not have to change if you move them?

• Do you want to reduce network HTTP traffic?

Answering yes to these questions suggests a two-tiered architecture.
