Webapp vs. site collection vs. site vs. app pool vs. ???

  Asked By: Callie    Date: Feb 03    Category: MOSS    Views: 1081

We finally have a test install of MOSS07 up and running for us to play
with. Reading through some of the stuff, I tend to keep getting hung up
on some of the basic terminology. I'm struggling to have a clear
definition for some of these. Below are the terms and my interpretation.
Please let me know if I'm in the ballpark or not. ;o)

Web Application = IIS Site
Site Collection = one Top Level site and all subsites that branch from
Site = Any site within a site collection
Application Pool = (I'm still not entirely sure about this one).

In general, what are the rules of thumb regarding Web Applications and
Site Collection relations. Should we have more than one Web Application?
If so, why/when should we? How many application pools should we have?

Application is in IIS. If you open your IIS, you will find it under
you computer name as a sub folder. This is where you define which web
application (Virtual Server) taking resources and isolated from
others. So, one application  Pool goes down will take all web
applications consuming it.

Based on what Darrel and cobrachen suggested, would this hierarchy be
correct in MOSS perspective?

IIS > Application Pool > Web Application > Site Collection > Site

At a basic  level, application  pools provide memory and security seperation to
the different web  applications. From a best practices perspective, you should
have a seperate application pool  identity for your central administration
application, and then another identify for each application after that. This
discussion usually gets a bit more murky, though, because each application pool
can require up to 200MB of RAM on your server and requires the administration of
another account. You would need to judge that requirement against your server
hardware and general  operating environment.
