Design Process

1. Problem Formation:

Obtaining AOL platform background Understanding AOL motivation

Forming the problem statement

2. Problem Solving:

Acquiring specificationsResearching web platform components

Identifying the desired components

3. Solution Implementation:

Setting up the selected platform componentsDeveloping a prototype application

Benchmarking and Evaluating the platforms

Project Overview

Background: AOL needs to change its web platform to match with the standard

industry web platform.

Motivation: Reduce development and maintenance time and cost

Design: Evaluate different sets of web platform (O.S, web servers,

databases, and web applications).

Goal: To know how the platform choice decisions are made.

Design Specification

OS : Unix/Linux

Application: Accessible over HTTP Port 80 Use a standard web services API (Application Programming

Interface) such as REST, XML-RPC or SOAP Access to another web services API via HTTP Database access

Research Results

O.S Component: Red Hat Linux Open Source Widely used for web servers Easy to update Good documentation Can cluster

Web Server Component: Apache Support all kinds of operating system The most popular web server

Prototype Application: Web Shopping Mall A lot of transactions between server and clients Fulfill specifications assigned

9

Research Results

Database Component: MySQL

Keep high performance during heavy traffic. Most common open-source database. More Application Support compared to PostgreSQL. Good Documentation / More Books

PostgreSQL Open-source Has transactional role back

Server Side Script: PHP Easy to learn Widely used with MySQL

10

Research Results Web service Access Protocol:

REST Simple interface Scalable 80% of Amazon Web Serivces API access Evolve from academic research

XML-RPC Does not have as much industry support as SOAP

SOAP More complicated Might offer more security features

RESTful SOAP ?
