| “ | We all know how the World Wide Web has changed our lives. It's how we buy books, make travel reservations, trade securities, track our favorite sports teams, and communicate with friends and family. The web also connects our businesses to one another, but not directly. My company can purchase goods from your company over the Internet, but only if someone at my end sits down in front of a computer and orders from your company's web site. The World Wide Web wasn't designed for direct business-to-business transactions. It's intended for use by people. Web Services Rather than place orders via your web site, I'd like my warehouse-management system to automatically re-stock items I buy from you whenever I start to run low, by communicating with your order-taking system over the Internet. That would be a true business-to-business conversation without the intervening human process, and that's what web services are all about. They're the second wave of e-commerce-a better way than we've ever had before of linking organizations. Service-Oriented Architectures Building the human-oriented World Wide Web was much easier than linking businesses over the Internet. Any company that wanted to open its doors for consumer e-commerce only had to develop interfaces between the internal systems already under its control and the new web standards: the HyperText Transfer Protocol (HTTP) and the HyperText Markup Language (HTML). But to deploy business-to-business web services, companies must link existing systems to an unpredictable variety of external ones-many based on decades-old technologies. Some of your partners' systems run Unix or Windows, while others are on older mainframe operating systems. Further differences in hardware and programming languages make linking these systems extremely difficult using their traditional application-program interfaces (APIs). Instead, you'll need to build systems that communicate using technology-independent services, and adopt service-oriented architectures (SOAs) designed expressly to meet the challenges of linking heterogeneous distributed systems. | ” |
