| h| Abstract |
| | Since the 1970’s it has been acknowledged that a |
| complex system can be broken into (a) its invariant functional |
| parts (mechanism), and (b) the externalized choices for how the |
| system should behave (policy). Policy-based management’s main |
| objective is to separate and externalize the decisions required by a |
| system from the mechanisms provided by the system, and provide |
| a way to define and evaluate these decisions. A few decades later, |
| we have today a plethora of different policy models and even more |
| policy languages – plus tooling – offering policy-based solutions |
| for virtually any use case and scenario. However, policy-based |
| management as a standalone domain has never been evaluated |
| in terms of which parts are variant / invariant, i.e. which parts |
| of policy-based management can be domain-, model-, language-, |
| usecase-independent. In this paper, we introduce and define a |
| formal universal policy model that does exactly that. The result |
| is a model that can be used to design, implement, and deploy |
| immutable policy infrastructure (engine and executor) being able |
| to execute (virtually) any policy model. |
