From Processes to Policies -- Concepts for Large Scale Policy Generation
Process-oriented IT management has gained more and more significance due to the
need to specify and control IT infrastructures and services. An indicator for
this circumstance is the success of the IT Infrastructure Library and the
enhanced Telecom Operations Map. A process-oriented view allows administrators
to specify management tasks and to decompose complex tasks into process chains
and hierarchies. Policy based management is a promising candidate for
implementation of processes, as it delivers a powerful concept for the
implementation of management tasks. Policies are well suited for large scale
systems, as the distributed execution in heterogeneous environments is one of
the important features of policy architectures.
In this paper we introduce patterns for the automated generation of
policies from process specifications. To achieve the translation
between process and policy specification, we leverage common
characteristics of processes and policies and define mappings that
serve as generic translation patterns. The use of these patterns
allows automated translation of process definitions to policies. The
approach enables high-level, intuitive management specification, while
taking a step towards augmented automation and integration at the
operational level. We derive requirements imposed by the translation
and present ProPolis, a policy language incorporating those
requirements.
