Web 2.0 Cloud Computing

Tim O’Reilly coined the term “Web 2.0” to describe a quickly-growing set of Web-based applications. The concepts of complexity-hiding and reuse, and loosely coupling services very obviously suggested the potential of combining technologies and principles of both Web 2.0 and SOA. As the world migrates to the Internet of Services, people, machines, and goods will have access via the network infrastructure. The multiplicity of available services will require a complex services infrastructure based on Cloud Computing, including service-delivery platforms bringing together demand and supply. Building blocks for the Internet of Services include SOA, Web 2.0, as well as novel business models, and approaches to systematic and community-based innovation.

Gartner analysts and others call this “advanced SOA,” “SOA 2.0,” or event-driven SOA. The idea is to combine the intelligence and proactiveness of event-driven computing architecture with the organizational capabilities found in SOA. Before event-driven SOA, the typical SOA platform orchestrated services centrally, through pre-defined business processes, assuming that what should have already been triggered is defined in a business process. This older approach does not account for events that occur across, or outside of, specific business processes.
