XML, SOAP and HailStorm: WebServices for Embedded Devices
Unlike inter-computer communication technologies of the past, embedded devices are able to play in the world of WebServices based on XML and SOAP. The open nature of XML, the standardization of networking protocols, the proliferation of TCP/IP stacks for embedded devices and the strong processing power of embedded CPUs all culminate in the ability for devices to interact and leverage WebService technology.
The key understanding how to take advantage of WebServices from an embedded device is first learning about the building blocks that are available to you as a developer. Although I will center around the technologies available on Windows CE, the information can be applied to almost any embedded operating system.
