Grid, SOA and Cloud Computing

Abstract

In this chapter we are going to introduce the key concepts of SOA, grid, and cloud computing and the relation between them. This chapter illustrates the paradigm shift in technological services due to the incorporation of these models and how we can combine them to develop a highly scalable application system such as petascale computing. Also there will be coverage for some concepts of Web 2.0 and why it needs grid computing and the on-demand enterprise model. Finally, we will discuss some standardization efforts on these models as a further step in developing interoperable grid systems.
