Towards a Dynamic On-demand Service Grid Based on P2P Network

Grid Computing has made it possible for users to execute computationally expensive applications on dynamically acquired distributed resources. Users are allowed to combine data and analysis components distributed over the globe to build new complex applications. This architectural concept is further enhanced by the introduction of on-demand dynamic service provisioning to create ad-hoc Virtual Organizations as done in DynaSOAr. In this working paper, we present the architecture of a Distributed Hash-table (DHT) facilitated framework, which uses Peer-to-Peer (P2P) concepts to enable dynamic on-demand service discovery and deployment on networked entities. One of the key features in this proposed framework is the use of decentralized Chord Ring instead of a centralized UDDI-based registry to cope with dynamic resource changes, thereby creating the basis of a fully dynamic virtual marketplace for computational resources.
