A new technology is doomed if it does not give new opportunities for the people concerned with making money. From a businessperson’s perspective, web services open new possibilities for the following reasons:
New payment structures: The user of a web service can pay a subscription fee for using the service. One example may be the news feed from Associated Press. Another possibility is a payperview, or micro payment, model. A provider of a credit verification service, for instance, may charge per request.
Real-time interaction and collaboration: Today, data is typically replicated and used locally.Web services enable real-time queries to remote data. An example is an e-commerce site selling computer games. The e-commerce site may hook up to a warehouse to get the number of items in stock in real time. This enables the e-commerce site to provide a better service. Nothing is more frustrating than buying something over the Internet just to learn the next day that the product you wanted is out of stock.
Aggregated services: A web service may aggregate other web services, screen-scraped websites, legacy components exposed using proprietary protocols, and so on. A typical example of an aggregated service is a comparative service giving you the best deal on products. Another type of service is one that groups related services. For example, imagine you’re moving to a new home. Someone could provide you with a service that can update your address at the post office, find the transportation company to move all your possessions, and so on.
Web services are by no means the only technology that can provide these solutions. Many similar solutions are available today using existing technology. However web services have the momentum and standards to make these kinds of services generally available.
