Apps inside different app pools on IIS 7.5

  • 772

I saw a guy a couple of days ago and he was putting his apps inside different app pools for each app. For example:

  • example.com inside examplePool - .net 4.0 integrated mode
  • example2.com inside example2Pool - .net 4.0 integrated mode
  • example3.com inside example3Pool - .net 4.0 integrated mode

I would understand the logic if the settings was different, but they weren't.

What I am doing is the complete opposite. All of my .net 4 apps (there are nearly 20) are running under one app pool.

So what is the best way of doing this on IIS 7.5?

iis iis-7 iis-7.5 .net windows-server-2008-r2

    Looking at the Managing Application Pools in IIS 7 TechNet page, it is simply to separate applications from each other. Here's the relevant bit.

    An application pool is a group of one or more URLs that are served by a worker process or a set of worker processes. Application pools set boundaries for the applications they contain, which means that any applications that are running outside a given application pool cannot affect the applications in the application pool.

    Application pools offer the following benefits:

    • Improved server and application performance. You can assign resource-intensive applications to their own application pools so that the performance of other applications does not decrease.

    • Improved application availability. If an application in one application pool fails, applications in other application pools are not affected.

    • Improved security. By isolating applications, you reduce the chance that one application will access the resources of another application.
