Recent advances in the business of cloud computing form just such a picture and reach out to encompass previously unrelated aspects of Web 2.0, the semantic web, platform computing, software as a service (SaaS), and the economics of disruption.

This is a guest post by Paul Miller, a Semantic Web and Cloud Computing expert who was most recently a Technology Evangelist at UK technology company, Talis.

Not merely some game of buzzword bingo on an unprecedented scale, cloud computing is coming into its own, and it is becoming increasingly easy to see the opportunities for a significant shift in the way we access computational resources and to recognize that the walls separating organizations from their peers, partners, competitors, and customers will become ever-more permeable to the flow of data through which those distant machines will compute.

There are many areas to understand that have already been ascertained in related fields, and many ideas unique to this space to discover. One early challenge is to carve a distinct niche for the place we are moving towards with such rapidity. Far more than "just" a cloud, it is an evolutionary cycle beyond the playful flippancy that diminishes so many of Web 2.0's poster children, and it is difficult to relate to mainstream misconceptions of the semantic web's complexity. Yet this new place is greater than the sum of its parts. So do we sustain the already ephemeral notion of cloud computing? Do we appropriate the "next big thing" label of Web 3.0? Or do we need a fresh attitude towards business computing's apparently insatiable desire to apply labels?

First, though, let us consider the shape of this thing that is taking on more substance with each passing day.

Reporting on last month's Web 2.0 Summit in San Francisco, CNET's Dan Farber notes that "the cloud was omnipresent," before closing his report with the observation that "cloud computing won't be very compelling without what is variously called Web 3.0 or the semantic web."

Indeed.

For too long, the emphasis in cloud computing circles has been almost exclusively on the provision of rapidly scalable and ad hoc remote computing on top of cost-effective commodity hardware. The cloud play by Salesforce, Amazon's EC2, and the rest has been dominated by the implicit assumption that these cloud-based resources are an extension of the corporate data center; a way to simply reduce the costs of enterprise computing.

There is value down this road, but there are bigger opportunities.
