Catallaxy-based Grid Markets

Grid computing has recently become an important paradigm for managing eomputationally demanding applications (composed of a collection of services). Providing dynamic discovery of services, and the determination of a service with the "best value" remains a complex problem in Grid computing. Such a decision is a multi-attribute n : m allocation problem, and often made using a centralized component in exiting systems. We propose a two layered architecture for service discovery in such Application Layer Networks (ALN) an Grids. The first layer consists of a service market in which complex services are traded, and can be chosen based on price and availability. The second layer provides an allocation of services to appropriate resources in order to carry out the specific services. This work comprises the foundations for the comparison of centralized and decentralized market mechanisms for allocation of services and resources in ALN and Grid markets.
