Servers: The Heart of IEBI</h2> <blockquote> <p><span>Unlike historians, those of us living through a crisis lack the luxury of assigning clever names to disagreeable events. Years from now the situation that I label "the disconnect" may well be known by a different term . The shorthand we use is irrelevant. The consequences we endure are not. By whatever designation, the disconnect that has evolved over the past 30 years between corporate executives and the managers of the information technology resource represents an enormous drain on the productivity and competitiveness of the United States. The disconnect has profound and sweeping implications for both you and your organization.</span></p> <p><span>Charles B. Wang</span><br><span>Techno Vision</span><sup>[1]</sup></p> <blockquote><p><sup>[1]</sup> Wang, Charles, <span>Techno Vision</span>, McGraw Hill, 1994. Used by permission.</p></blockquote> </blockquote> <p>Charles Wang's book <span>Techno Vision</span> was published in 1994, the dawn of e-commerce. In this work he describes a disconnect between those who use information and those who maintain it. In this chapter we will examine some of the causes of this disconnect as well as its implications. Of course, we have an advantage over Charles Wang: We can look back. We are not in the heat of the situation. We can see not only the disconnect, but how it has been one of the catalysts for the integration of the Internet into the information infrastructure of many organizations.</p> <p>In Chapter 2, we described the birth of the Internet as the point at which we established communication between two systems. In these early days, systems residing on a network were peer to peer; they were relatively equal in their responsibilities on the network. As the Internet developed, this changed. We moved from a peer-to-peer network to architectures that divided the responsibilities for certain tasks between systems. This gave rise to the server.</p> <p>In this chapter, we examine the heart of the network, the server. We begin our study with a look at the mainframe and how it fits into the Internet-enabled world. As we shall see, the shortcomings of the mainframe gave rise to a new paradigm, client/server. While giving users greater access to information, client/server architectures have issues of their own. The next step in the evolution of information systems, the Internet-enabled application, provides a solution to many of the challenges offered by client/server.</p> </td></tr></table> <hr size="1"> <table width="100%" border="0" cellspacing="0" cellpadding="2"> <tr><td valign="top" height="5"><img src="/books/2/551/1/html/2/images/pixel.gif" width="1" height="5" alt="" border="0"></td></tr> <tr> <td><b><font size="1" color="#0000FF">Team-Fly<img border="0" src="/books/2/551/1/html/2/Fly-Logo.gif" width="81" height="25"></font></b></td> <td valign="top" align="right"> </td> </tr> </table> <table width="100%" border="0" cellspacing="0" cellpadding="0"><tr><td valign="top" align="right">Top</td></tr></table> </td></tr></table></td> <td align="center"> </td> </tr> <tr><td colspan="3" align="center" valign="bottom"> <br><table width="100%"><tr><td height="25" valign="middle" colspan="4" align="center"> </td></tr></table> </td></tr> </table> </blockquote>
