An Architectural Framework for Enforcing Energy Management Policies in Cloud

Management of energy consumption in Cloud has recently received considerable attention. Most existing research focuses on designing algorithms for dynamically managing the running of virtual machines in Cloud, such as placement and migration algorithms. Despite the use such on-line algorithms being essential, another equally important dimension that is related to High-level policies and guidelines that are set by Cloud Mangers or Administrators for management energy consumption. Such policies often stem from business, legal and financial requirements. Currently, most implementations of High-level policies such as Management Energy Consumption Policies are done manually via the use of low-level programming languages and APIs for accessing Cloud interfaces. Since High-level policies can change frequently, the manual implementation for such policies increases the cost and the time of the development and maintainability. Thus, there is a clear need for a methodical way of executing High-level policies automatically in Cloud. In this paper, we propose a generic architectural framework for enforcing High-level policies particularly Management Energy Consumption Policy in Cloud via using a Business Rule Engine. The generic architecture is implemented to execute Energy Management Business Rules to fire management actions in Open- Nebula cloud environment.
