INFRASTRUCTURE
ACTIVITY – INTERNET INFRASTRUCTURE
COMPONENTS
Write down all the different types of hardware and software
involved from when a user types in a web address such as
www.google.com to the web site being loaded
Why do business managers need to know about the jargon and
technology?
ACTIVITY 3.1 INFRASTRUCTURE RISK
ASSESSMENT
Make a list of the potential problems for customers of an online
retailer
You should consider problems faced by users of e-business
applications who are both internal and external to the organization
Base your answer on problems you have experienced on a web site
that can be related to network, hardware and software failures or
problems with data quality
TYPICAL PROBLEMS
Web site communications too slow
Web site not available
Bugs on site through pages being unavailable or information typed
in forms not being executed
Ordered products not delivered on time
E-mails not replied to
Customers’ privacy or trust is broken through security problems such
as credit cards being stolen or addresses sold to other companies

HTML AND XML
HTML (Hypertext Markup Language)

Elements of e-business infrastructure that require management
WEB SERVICES, SAAS, AND SOA

necessarily on the same machine or the same network
SaaS—applications are licensed to customers for use as a service
on demand

A collection of services that communicate with each other as part of
a distributed system
The motive is to develop applications that are independent of
hardware, OS, language, etc.
