Lesson 8 Infrastructure technologies
Objective Describe the effect of infrastructure technologies on the Web.
As information systems become more distributed, the network becomes a very integral part of the application system.
Many business characteristics of the application actually are beginning to be rendered by the network in general, and the "transport protocols" in particular.
In the real world "resources" are allocated by the prominence of the user. For example, a first-class airline passenger is always in a smaller queue or boards the aircraft before everybody else, and high net worth banking clients have personal bankers. This prioritization of users based on their profile, results in exclusive and guaranteed resource availability.

In a distributed application, a network is a very important resource. Making it available, based on business rules, has promulgated the network into such prominence that it has become an inseparable part of designing the business application itself; hence, the architecture. This Web-initiated business requirement is met in the marketplace by new products made available by network providers. The essential functional characteristics and their relevance to business imperatives are outlined in the following lesson.
Infrastructure technologies are the foundation technologies upon which all other e-Business services and customer experiences are built.
