suresh In IIS, a website and an application pool serve different purposes and have distinct functionalities.
A **website** in IIS can be seen as a container for hosting and managing web applications, content, and services. It is identified by a unique hostname, IP address, and port number combination that users can access over the internet. A website can host multiple web applications and content and can have various configurations such as binding, authentication, and access control settings.
On the other hand, an **application pool** in IIS is responsible for running one or more web applications within a website. It provides a way to isolate web applications from one another to ensure that if one application crashes, it does not affect others running in different application pools. Each application pool can have its own set of configurations such as .NET framework version, managed pipeline mode, maximum CPU usage, and recycling settings, allowing for better performance and reliability.
In summary, while a website is the container for hosting web applications and content, an application pool is the environment in which those web applications run independently to ensure stability and performance.
