2 iSeries Access for Web V5R2 and WebSphere Host Publisher V4.0
1.1 Today’s environment
The manner in which many companies conduct their business has changed significantly over
recent years. The Internet provides a prime market for many companies, and has created a
huge paradigm shift in the way that the market is viewed.
There are increasing business pressures to ensure continuous system availability and to use
information technology personnel in the most efficient manner. These pressures have
contributed to the drive to simplify the desktop environment and move to more open
standards of access to business systems.
1.2 Internet connectivity
The Internet has come to dictate changes in the way business is conducted. In fact, many
companies have developed dependence on Internet connectivity for information and e-mail.
Internet connectivity is viewed as inexpensive and an essential addendum to mainstream
business.
The benefits of Internet connectivity to the business community reach beyond sales and
corporate image. The Internet is a prime factor in social and technological evolution,
accelerating technological change at an unprecedented rate.

1.4 iSeries platform
The IBM iSeries server hardware platform has a distinguished heritage. IBM is justifiably
proud of the record it has established with this product in the midrange system marketplace.

facilitate the migration of traditional 5250 environments to a Web-based application
environment on the iSeries.
