What Is Advanced Web Services?
Web services are the backbone of the modern internet. You know them as the software that powers your favorite apps, but you might not know that they're also the foundation for everything from Twitter to Google Maps. But what's a basic web service? It's the kind of thing that uses SOAP, WSDL and UDDI—the most common standards for web services. They're great in their own right, but they're just not cutting it anymore: they can't handle complex security scenarios and have trouble with things like streaming video. That's where Advanced Web Services come in. Advanced Web Services go beyond SOAP, WSDL and UDDI to provide more robust capabilities for handling complex security scenarios and streaming video. Like all good things, web services become more advanced as they age. When Web Services Interoperability (WS-I) was introduced, it was revolutionary—a way of standardizing the exchange between different kinds of software by using XML and SOAP. It meant that businesses could talk to each other without having to spend millions on custom integration work. But now? It's just another standard—you can get a lot of it for free from many different providers, and most large companies have some kind of implementation in place. The next step is Advanced Web Services bundle basic Web service standards such as SOAP, UDDI and WSDL capabilities, incorporate Web Services Interoperability (WS-I) and include security standards like WS-Security, and then go beyond that by incorporating more advanced and sometimes proprietary security features and interactions When it comes to web services, there's the standard stuff, and then there's the advanced stuff. When you're looking for a web app, you want something that can handle complicated security interactions—and be ready for anything. That means looking for a service that supports WS-Federation and WS-Trust standards and asynchronous and parallel behavior through WS-ReliableMessaging. These advanced standards have been slow in acceptance because of the slow pace of ratification and rollout and because many existing applications and their interactions do not require the capabilities of these new and more advanced standards, or they use other methods to achieve them.
