1. Existing systemy Web server can refer to either the hardware (the computer)

or the software (the computer application) that helps to

deliver content that can be accessed through the Internet.y The most common use of web servers is to host web sites

but there are other uses such as data storage or running

enterprise applications.

y The primary function of a web server is to deliver webpages on the request to clients.

Features of the Enterprise web

services.y Security, an enterprise web site host should have adedicated team of security.

y Scalability, an enterprise web site host should be able to

upgrade the system.

y Availability, the network should always be up and running

so users/clients can get to your web site .

y Performance, the network (low latency) along with the

computer itself should be setup such that performance isof utmost importance.

y Reliability, the network should be reliable, much like

availability, and the servers themselves must be reliable.

2. Software Requirement

An

alysis(In

troduction

s)y First was Linux and second was windows. I select

linux as my final option, because it is free, open-sourceand stable operating system in comparison with

windows.

y I chose to develop the control panel in php, which ishighly supportable on linux systems along with theapache server, which also gives its best performance

with the linux systems. Finally i can say that i opted forthe LAMP architecture which suits my needs at thebest level in comparison of others.
