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

Computing
• 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.

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.
