"Feedback Circuit" is very old concept that could be traced back prior to WWII.

In the information system design, the concept is very useful to design a healthy, fault-tolerant application or data center infrastructure depending on the specific layer focused.

For example, in an application design, the business logic can be created based on the feedback from applications, such as the number of logged-on users, number of threads/sessions and so on ... In a data center (private cloud) infrastructure design, the feedback taken from network/server usage data can be used as input to dynamically provision or de-provision resources.
