Service Provisioning Framework for a Self-Organized Grid

Efficient, scalable and robust grid service provisioning is one of the cornerstones of next generation grid systems. In agreement with this vision, we propose a flexible grid service provisioning framework built on a two layer architecture. A lower layer provides membership management and basic communication upon a self-organized peer-to-peer overlay maintained and optimized using a fully distributed bio-inspired algorithm. An upper layer exploits these facilities to deliver high-level grid services such as resource discovery and monitoring. We evaluate the proposed solution on different scenarios and assess its qualities concerning performance, reliability, fault-resilience and network communication efficiency.
