Separate application pools for ASP.net applications in IIS

Question

I\'ve read recommendations that we should create separate application pools for each asp.net application on our Win2008 server.

We have about 20 apps that would be on t

Answer 1

yes, it is a good idea even for 20 applications.

1. Security. Different app pools running under different accounts.
2. Isolation. One crashing app won't take down other apps.
3. Memory (if you are running 32bit). Each app pool will have its own address space. Thus you can address much more memory than a maximum of approximately 2.7GB of usable space for 1 process.
4. You may choose to periodically restart one not-so-well behaving app without affecting other applications.
