Annotation P2P, Grid, Cloud and Internet computing technologies have emerged as new paradigms for solving complex problems by enabling large scale aggregation and sharing of computational, data and other geographically distributed computational resources Rapid advances are being reported by many researchers and forums as regards understanding numerous issues in such paradigms, from theoretic to application aspects The continuous development of Internet and the construction of new P2P and Grid and Cloud computing infrastructures are making possible the development of large scale applications from many fields of science and engineering Grid Computing originated as a distributed paradigm for scientific high performance computing (Distributed Supercomputing, High Throughput Applications, Data Intensive Applications, etc ), as an alternative to expensive supercomputers by virtually joining a large number of interconnected computers Since late 80 s, Grid computing domain has been extended to embra
