IJGUC addresses grid and utility computing which represent fundamental paradigms for next-generation parallel and distributed computing systems, enabling distant collaboration, resource discovery/sharing, data-intensive applicative infrastructures and high-throughput environments to address on-demand large-scale scientific, engineering, and business problems. Grid and utility computing have significantly contributed to the advancement of cloud computing, e-science, high performance computing, virtual organisations and collaboration, scientific workflows, and service-oriented architectures. They exploit synergies with different areas such as peer-to-peer computing, semantic web, wireless/mobile technologies, and computational intelligence.
