Application pools in Internet Information Services (IIS) is used to host multiple websites or applications on a single server

Here are some key points for the Application pools in IIS are given below

• Improved site reliability: Application pools enable you to deploy applications on multiple application pools. This isolation prevents apps from affecting the performance of each other. Also, the application pool recycling feature helps automatically restart work processes to refresh faulty applications. It helps ensure the applications run smoothly without crashes or memory leaks.

• Better application availability: Application pools help improve the availability of apps or sites. When applications running on one application pool aren’t impacted by errors in applications running on different application pools, even when hosted on the same server, it leads to an improved app or site availability.

• Improved Security: Application pools enable you to secure application pools from each other by configuring different security settings for various sites or apps. Moreover, the “Application Pool Identities” is a powerful security feature in IIS that allows you to run each application pool under a unique account by using a specific identity. The name of the application pool account is the same as the application pool itself. There’s no need to develop and manage multiple domain or local accounts. Keep in mind this application pool account isn’t a real user account and is used primarily as a security identifier.

• Ease of application management: By leveraging the isolation feature of application pools, you can assign different settings and .NET versions for various applications and easily separate resource-intensive apps from each other. Because of this, application pools help with overall improved application management.
