Emerging technologies provide opportunities for new services • Tools and features previously available only

Emerging technologies provide opportunities for new services • Tools and features previously available only in integrated systems can now be provided as 'web services' • “network accessible application components” • “interoperable building blocks for constructing applications” • “self-describing applications that can be discovered and accessed over the web by other applications” • Technical definition – Web Services are a suite of protocols that define how requests and responses between software applications should be encoded & transferred over the web
