In this paper, the benefits of grid technology are examined by comparing certain functionalities and capabilities found in Web Services with those found in Grid Services. Grid Services build on the conventions and practices used in Web Service development together with the harnessing of power and uniformity of structure based in grid technologies. The argument here is not if all that is possible using grid technologies and Grid Services is also possible using Web Services, rather it is a question of what these grid solutions can offer beyond the current scope of Web Services. Differences between the two are clearly apparent in the abstraction inherent in the Grid Service naming scheme and the level of functionality guaranteed with Grid Services, but not Web Services. The distinction in usability is also quite notable in many real-world cases in which grid technologies are preferred to Web Services. The examples of the Condor Project of the University of Wisconsin demonstrates the advantage in scalability and customization available using grid technologies while the example of Axyz Animation, Inc. showcases the capability of grid technologies for the small-to-mid size business. It becomes quite clear that the advantages offered by grid technology in both uniformity and structure, as well as real-world applications, give a clear cut edge which is not likely to be taken away by Web Services any time soon
