Complex web services, Grid resource characteristics, and Cloud services are commonly represented by a number of attributes such as service type, hardware (processor type, speed), installed software (libraries, operating system), service name, security (authentication and authorization control); efficiently discovering the aforementioned services with deterministic guarantees in decentralized and scalable manner requires lookup queries to encapsulate search values for each attribute (search dimension) . The search is resolved by satisfying the constraints for the values expressed in each dimension, hence resulting in multi-dimensional queries that search for values in a virtual space that has multiple dimensions (x, y, z…).

Abstract
This chapter describes Aneka-Federation, a decentralized and distributed system that combines enterprise Clouds, overlay networking, and structured peer-to-peer techniques to create scalable wide-area networking of compute nodes for high-throughput computing. The Aneka-Federation integrates numerous small scale Aneka Enterprise Cloud services and nodes that are distributed over multiple control and enterprise domains as parts of a single coordinated resource leasing abstraction. The system is designed with the aim of making distributed enterprise Cloud resource integration and application programming flexible, efficient, and scalable. The system is engineered such that it: enables seamless integration of existing Aneka Enterprise Clouds as part of single wide-area resource leasing federation; self-organizes the system components based on a structured peer-to-peer routing methodology; and presents end-users with a distributed application composition environment that can support variety of programming and execution models. This chapter describes the design and implementation of a novel, extensible and decentralized peer-to-peer technique that helps to discover, connect and provision the services of Aneka Enterprise Clouds among the users who can use different programming models to compose their applications. Evaluations of the system with applications that are programmed using the Task and Thread execution models on top of an overlay of Aneka Enterprise Clouds have been described here.
