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 http://rapidshare.com/files/3114662/NI1881378241.rar
