INTRANETS

An intranet is service making use of the technologies of the world wide web (usually HTML over HTTP) to distribute information within a single organisation over it's internal network. Note that the intranet is no longer the network itself, but a service run over it.

INTRANETS

Intranets offer the following application feature set:• rapid prototyping (can be measured in hours or days)• scalable (start small, build as needs, requirements allow)• easy navigation (internal home page provides links to

information)• accessible via most computing platforms• can integrate distributed computing strategy (localized

web servers residing closer to the content author)• can be tied in to "legacy" information sources

(databases, existing word processing documents, groupware databases)

• extensible to a variety of media types (audio, video, interactive applications)

INTRANETS

The benefits to these features are many, including:• inexpensive to start, requires little investment either in

dollars or infrastructure

• significantly more timely and less expensive than traditional information (paper) delivery

• distributed computing strategy uses computing resources more effectively

• users familiar with link metaphor from surfing experiences

• open platform architecture means large (and increasing) number of add-on applications available

INTRANETS

Intranets Support Distributed Computing Strategy

 • An additional driver in the growth and speed of this

adoption curve is the fact that Intranet applications can fully support a distributed computing strategy - one that places the server and content closer to the owner of that content.

Payments

• There are several categories of payment, • credit card transactions, • electronic fund transfers • and telephone billing systems. • No solution is perfect and each comes with its own set of

advantages and disadvantages. The right choice for you depends upon your specific business requirements.

Security

• security, - different levels of security• Who can access what?• Who decides access levels?• How are they administrated?• Privacy – how is it managed - data protection act – who

should be allowed to see the data?• These services make life easy for IT managers, since

everything can be centrally managed, and capabilities like security and directories are built right in.
