The Policy Manager GE provides the basic management of cloud resources based on rules, as well as management of the corresponding resources within the FI-WARE Cloud Instance like actions based on physical monitoring or infrastructure, security monitoring of resources and services or whatever that could be defined by a facts, actions and rules.
The baseline for the Policy Manager GE is PyCLIPS, which is a module to interface CLIPS expert system and python language. The reason to take PyCLIPS is to extend the OpenStack ecosystem with a expert system written in the same language that the rest of the OpenStack services. Hence, Policy Manager offers the decision-making ability, independently of the type of resource (physical/virtual resources, network, service or whatever), able to solve complex problems within the Cloud field by reasoning about the knowledge base, represented by facts and rules.
