Inherent to the cloud computing paradigm is the ability to adjust or deploy, on demand, services to face dynamic changes on the workload. Therefore, one needs an infrastructure to keep track of the resource allocation in the system and to efficiently locate the resources required to launch a new service, or re-dimension a running service. In this paper we propose a novel peer-to-peer architecture for efficient resource location that avoids the bottlenecks of centralized or hierarchical directory services.
