Abstract
This paper discusses the problem of planning resource outsourcing and local configurations for infrastructure services that are subject to Service Level Agreements (SLA). The objective of our approach is to minimize implementation and outsourcing costs for reasons of competitiveness, while respecting business policies for profit and risk. We implement a greedy algorithm for outsourcing, using cost and subcontractor reputation as selection criteria; and local resource configurations as a constraint satisfaction problem for acceptable profit and failure risks. Thus, it becomes possible to provide educated price quotes to customers and establish safe electronic contracts automatically. Discarding either local resource provisioning, or outsourcing, models efficiently the specialized cases of infrastructure resellers and isolated infrastructure providers respectively.
