Themashup is also cool, which impresses his friends. Many pressures will move as much of thesituational applications to enterprise servers as possible. The team develops an ISB application by associatingpolicy and function with URIs. The ISB links devices to eachothers, devices to local servers, Web sites to Web sites, and ESBs to ESBs, andis itself an ESB. This contrasts with Salesforce. com, which was initiallypackaged application software as service. The core ISB concept is built around aUniform Resource Identifier URI space. The composite application is set of URIs,policies and functions.

The data center needs to manage dozensof heavily loaded core application servers accessed by thousands of users, andthousands of virtual servers infrequently access by small teams using ad hocapplications. Consider what happens if an airline cancelsDaves connecting flight from Dallas to San Francisco and he willneed to stay overnight in the connecting airport city. Themashup is also cool, which impresses his friends. Many pressures will move as much of thesituational applications to enterprise servers as possible. This is the Internet Service BusISB.
