Computing paradigm focusing on provisioning of metered services related to the use of hardware, software platforms, and applications, billed on a pay-per-use base, and pushed by vendors such as Amazon, Google, Microsoft, Salesforce, Sun, and others. Accordingly, there are many different (but similar) definitions (as with Grid Computing).

Abstract
Aim of this chapter is to guide developers and users through the most important stages of implementing software applications on Grid infrastructures, and to discuss important challenges and potential solutions. Those challenges come from the underlying grid infrastructure, like security, resource management, and information services; the application data, data management, and the structure, volume, and location of the data; and the application architecture, monolithic or workflow, serial or parallel. As a case study, the author presents the DEISA Distributed European Infrastructure for Supercomputing Applications and describes its DEISA Extreme Computing Initiative DECI for porting and running scientific grand challenge applications. The chapter concludes with an outlook on Compute Clouds, and suggests ten rules of building a sustainable grid as a prerequisite for long-term sustainability of the grid applications.
