Hosting webapplication in multiple webservers using load balancer is called as Web Farm.To avoid the high load in single server this load balancer method will use to distribute the traffic to different server on same web application.
Configure multiple work process on one application pool in a web server is called as Web Garden.Application Pool can configure for multiple websites hosted in IIS.
For IIS 6.0 – NetworkServices,LocalService,LocalSystem
For IIS 7.0 – NetworkServices,LocalService,LocalSystem and Application Pool Identity.
For IIS 6.0 > w3wp.exe
For IIS 7.0 > w3wp.exe
in IIS 5.1 worker process is aspnet_wp.exe.
1. DefaultAppPool (Integrated)
Use the following command “IISRESET”.

Application Pool stated that Multiple web applications or Group of web applications.
Application pool contain one or more Web URLs used by Worker processes.For one website or many website we can assign Application Pool, to avoid the effect of other website need to create seperate Application Pool.
App Pool and App Domain both are for isolations on different approches.App Pool use process to isolate without .net but for App Domain isolation methods by .net.
In Simple terms
For Multiple websites in IIS need different Application Pool.
In Single domain purpose we use Application Domain.
Two types of layers in IIS:
Under Main Layers sub contents are:
HTTPS.SYS key component in Kernal level.It process the queue which hit the client request for each Application Pool depend on request.While create any new Application Pool IIS will register the Application Pool with HTTP.SYS.
1.Anonymous ( Default Authentication in IIS runs under IUSER_servername )
2.Integrated Windows Authentication
Right click on Application Pool ->All Task ->Save Configuration to a File.
It will save the configuration file in xml format.
First identify the Application pool name and process ID using cscript iisapi.vbs script.Later attach process from Visual Studio IDE.
ISAPI filters are DLL files used to modify the enhance functionality allocated by IIS.By default ISAPI filters run in IIS server.
SVCHost.exe is the key component of www publishing service (w3svc) and Windows action Process(WAP)(WAP for start and stop the process).
W3SVC is the mediator for HTTP.SYS and WAP(windows activation process)

When we hosted our web Application on multiple web server under a load balancer call the Web Farm. This is generally used for heavy load web application where there are many user requests at a time. So When Web Application is hosted on Different IIS Server over a load balancer, Load balancer is responsible for distribute the load on different server.
Run cscript iisapi.vbs script to find out the process ID and Application Pool name . Based on the process Id for particular application I have to attache the process from Visual studio IDE.
We can easily debug any web application that are hosted on IIS by using Attaching of Worker Process.
From Visual Studio IDE > Tools > Attach To Process
Select the particular Process, then start debugging.
IIS should periodically monitor the health of a worker process [ Idle or not , Time for recycle or not, All Worker process are running properly or not ] .
Pining means, Activation Process monitor Worker process performance, health, idle time etc.
By default it sets to 30s .
