Web Services and Service Oriented Architecture (SOA) are a set of emerging technologies and concepts that are designed to enable application systems to seamlessly integrate.  The systems can run either on the same computer or on different computers that are connected via a network.  A high-speed SDSL connection can be used to connect the computers via the Internet.

Historically, it has been very difficult to get computer systems to "talk".  Vendors have routinely develop proprietary software that don't adhere to open standards.  Consequently, businesses have often been forced to purchase software packages from the same vendor if they want their systems to integrate.  Because Web Services and SOA are platform independent and vendor neutral, different types of systems can now integrate electronically.

To communicate with other systems, SOA applications exchange messages using XML stored in plain text files.  Just as HTML has allowed computers to share information visually across different platforms, operating systems, and types of hardware, XML is now allowing information exchange to occur using non-visual interfaces.

A high-speed broadband connection like SDSL is required for computers to pass XML messages from one computer to another.  Because SDSL is able to send and receive data at the same bit-rate, it is well suited for SOA applications.

The diagram above depicts information being shared between a Widget business and its suppliers and consumers, using SDSL Internet connections and platform independent web services.
