Revolutionize the corporate computing model for software-producing
companies, for software-consuming companies, for hardware and
infrastructure companies, and for services companies.
Specifically, Web services promise to deliver the following high-level
benefits to organizations:
Support application integration internally and externally, across the
Provide easier B2B collaboration between business partners.
Transition software deployment models from big-bang, high-footprint
implementations to just-in-time applications that are appropriate to
the business challenge being addressed. This is the beginning of the
idea of Just-in-Time Information Technology based on Web services.
Software rental models and grid computing are simply specific subsets
of the idea of JIT IT.
Reduce costs of software procurement, deployment, and integration.
Increase business and technology agility by deploying loosely coupled
business applications versus monolithic enterprise applications.
Why Was the Internet Not Sufficient?
One question about the Internet is why it was not robust enough for true
B2B collaboration, as well as for complex processes that span multiple
Web sites or multiple organizations for Web transactions. The Internet
rapidly evolved for B2B transactions, yet it fell short for complex collabo-
ration between organizations due to the following issues:
Lack of standards for B2B integration and B2B automation
Manual searching of Web content by browsers versus registry-based
applications that find one another and auto-invoke (this result is a
future but possible scenario)
Emerging standards such as XML have already become fragmented,
diminishing their ability to create consensus among industry solution
providers and consumers
Internally-focused application procurement and deployment models
Of all these, the most difficult to overcome is probably the internal IT
architectural models of organizations. Internally focused application pro-
curement and deployment models have to date dominated the IT architec-
ture of organizations, in contrast to collaboration-centric application
models. Most IT architectures of todays corporations are based on a single-
company view of their own internal operations. That is not necessarily bad
or wrong. It merely means that an organizations investment in its IT
