Introduction Background Problem Statement Design Criteria Proposed solution Evaluation Alternative solution Recommendation Budget Gantt chart

Background AOL 1978 AOL founded 1991 DOS version of AOL is launched AOL launches windows version. FDO (Forms Documents Objects) AOL in-house Protocol for connection to the server

How is your connection?

Problem Statement Paradigm changed From ‘dial-up’ to ‘always-on broadband’ using HTTP FDO interacts with users HTTP only responds when users request Open Source software Less expensive or nearly free of charge Expensive to develop AOL own platform

Design Criteria OS – Unix/Linux Application Accessible over HTTP Port 80 Use a standard web service API (Application Programming Interface) such as REST, XML-RPC or SOAP Database access Access to another web services API via HTTP

Proposed Solution Phase I: Research Operating System: Linux, FreeBSD, Solaris Web Server: Apache, AOL Server Database: MySQL, PostgreSQL Application language (XML) Design prototype web application Develop testing methodology. Web Platform Performance Level (PPL) Web Application Performance Level (APL)

Proposed Solution Phase II Install Platforms Implement the Prototype Application on each platform Application Online Shopping System

Evaluation Phase III Testing the different platforms based on the methodology. App1 App2 Server Response TimeTCP Connection TimeData CompressionPlatform Support … … Web server testing

Alternative Solution Microsoft.NET platform Windows 2003 Server ISS (Internet Information Server)

Recommendation The goal is to recommend a platform for AOL based on evaluation. OS Web Server/container Database Web Services API

Budget Computer Hardware Dr. Hariri (ITT lab) Software Open source software Total budget : $0.00
