On the Horizon
As memory becomes more affordable, devices become more compact and networks become more ubiquitous, scenarios that were once nothing more than visions are beginning to become reality. These scenarios leverage the pervasiveness of computing devices and networking capabilities, offering possibilities in which the boundaries between human and computer, and between mobile device and supercomputer are blurred. Approaches drawing on these trends go under different names, and have different areas of focus. In this chapter we look at some of the paradigms and concepts that are defining next-generation distributed systems, beginning with systems and technologies that are already being implemented and used, and moving towards the more esoteric visions proposed by contemporary commentators.
