Difference between Web Garden and Web Farm?

Answer:

Web garden and web farms are asp.net applications that serve the purpose when the
user base of a web site increases considerably.

Web garden is a web application running on a single computer with multiple
processors but Web farm is a web application running on multiple servers. The
benefit of using this is, if one server crashes then other will work instantly.

For Web garden/Web Farm configurations, we have to set sessionState mode to
StateServer/SQLServer in the web.config file.

For Web Garden, we have to use

<processModel webGarden="true"/>

in Machine.Config file.

Web Farm is implemented using techniques like Net Work Load Balancing.
