IIS Application Pool contains all web applications on domains hosted on your server. Dedicated IIS application pool allows your clients to have a level of isolation between web applications used by their domains. Since each dedicated application pool runs independently, errors in one application pool belonging to one client will not affect the applications running in other application pools belonging to other clients.
By default, Parallels Plesk Panel offers a shared application pool for all your clients and their customers. However, clients and domains can use dedicated application pools if administrator and client policy permit this.
