Background

AOL




1978 AOL founded
1991 DOS version of AOL is launched.
1993 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




Open Source software


From ‘dial-up’ to ‘always-on broadband’ using
HTTP
FDO interacts with users
HTTP only responds when users request
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


Email Application
Online Shopping System
Evaluation
Phase III
App1
App2
Platform Support
Data Compression
Web server testing
Testing the different
platforms based on
the methodology.

Windows 2003 Server
ISS (Internet Information Server)
Recommendation

The goal is to recommend a platform
for AOL based on evaluation.
