Automation helps finish a known task faster, for example, a blender that chops vegetables. Orchestration, on the other hand, ensures that the entire workflow is adopted as per known recipe. Closed Loop Automation is akin to tasting the dish and adjusting the recipe until you reach the perfect flavor and aroma.
By closing the loop, you ensure the system works as intended. This concept is also known as Intent Based Networking (IBN) or Intent-Driven Networking (IDN).
