Special section on autonomic cloud computing: Technologies, services, and applications

The November 2011 special issue of Concurrency and Computation: Practice and Experience offers papers from autonomic cloud computing: technologies, services, and applications. Richter and co-researchers propose an algorithm for the decomposition of global utility boundary into atomic service utility boundaries, and the surplus redistribution from successful negotiation outcomes among the remaining negotiations in their paper titled 'Establishing Composite SLAs through Concurrent QoS Negotiation with Surplus Redistribution'. In the paper titled 'A data dependency based strategy for intermediate data storage in scientific cloud workflow systems', Yuan et al. build an intermediate data dependency graph (IDG) from the data provenance in scientific workflows. In the paper titled 'Towards autonomic management for Cloud services based upon volunteered resources', Caton and Rana propose a methodology that addresses the issues of unreliability and unpredictability such that Cloud software services could be hosted upon volunteered resources.
