Abstract: Controllers in computer systems have mainly been explored for automating regulative tasks such as admission control or resource supply control. The majority of IT management tasks, however, relies on discrete management states and coordinated transitions between those states. The paper shows how the concept of a feedback system can also be applied to automate operational management tasks. The paper introduces the concept and a realization of an IT Management Automation Controller, which operates on discrete management states expressed as a pair of models for desired and observed state. Models are represented as a special form of Place-Transition Nets (PTN or Petri Nets). Controller logic directly executes PTN in order to achieve and maintain alignment between desired and observed state in a managed domain. In contrast to workflow systems, PTN combine the description of state and actions in one model (graph). Three operational database management tasks have been implemented as a proof of concept in a blade server automation infrastructure using the Management Automation Controller.
