WW Web Production Services North 2 © 2005 IBM Corporation Part two  What exactly is a web application? –What roles exist within a web application? –Where do AMP and IBM tools fit in?

WW Web Production Services North 2 © 2005 IBM Corporation Web applications 101  What you use the web for –Selling products ibm.com –Publishing information cnn.com –Web-enabling traditional applications w3.ibm.com/hr

WW Web Production Services North 2 © 2005 IBM Corporation Web applications 101  What do they all have in common? –Web server –Application layer –Database

WW Web Production Services North 2 © 2005 IBM Corporation Web applications 101  Web server –The waiter You request an item, it goes somewhere and returns it. –Can return something “static” like a fork –Can return something “prepared” on demand, such as a ham and cheese sandwich

WW Web Production Services North 2 © 2005 IBM Corporation Web applications 101  Application server –The cook Accepts a request from the waiter to prepare something May need to consult other resources to get information on how to prepare it

WW Web Production Services North 2 © 2005 IBM Corporation Web applications 101  Database server –The cook book Stores recipes and organizes them by categories and indices

WW Web Production Services North 2 © 2005 IBM Corporation Competition  Web servers (the waiters) –Apache –IBM HTTP Server Is Apache under the hood  Attributes –Both share the lightweight, proven, modular core –IHS adds GUI configuration and maintenance tools

WW Web Production Services North 2 © 2005 IBM Corporation Competition  Application layer (the cooks) –PHP The Zend Engine interprets code written in PHP –WebSphere Application Server WAS provides services to programs written in Java according to J2EE specifications  Attributes –Both perform business logic such as processing orders or formatting articles

WW Web Production Services North 2 © 2005 IBM Corporation Competition  Database servers (the cookbooks) –MySQL –DB2 Universal Database  Attributes –Store information –Provide access to that data based on rules

WW Web Production Services North 2 © 2005 IBM Corporation Coexistence  You can mix and match technologies to fit each role –Apache / WAS / DB2 –IHS / PHP / MySQL –Apache / PHP / DB2  You can run them side by side –Apache or IHS can take a look at a request and send it to either WAS or PHP –PHP can connect to both MySQL and DB2 –Can use MySQL for logging and DB2 for customer information

WW Web Production Services North 2 © 2005 IBM Corporation Strengths and weaknesses  Why would you mix and match or choose one over the other if they both fit the same role? –Cost –Security –Support –Portability –Scalability –Standards –Frameworks

WW Web Production Services North 2 © 2005 IBM Corporation Strengths and weaknesses  Why would you mix and match or choose one over the other if they both fit the same role? –WAS vs. PHP Licensing cost Speed of development Standards and frameworks Customization

WW Web Production Services North 2 © 2005 IBM Corporation Strengths and weaknesses  Why would you mix and match or choose one over the other if they both fit the same role? –DB2 vs. MySQL Licensing cost Support Platforms Installation

WW Web Production Services North 2 © 2005 IBM Corporation Part two summary  IBM and AMP tools compete for web application roles, but can be mixed and matched or run concurrently  You can ease migration, it’s not one stack or the other  Questions and answers

WW Web Production Services North 2 © 2005 IBM Corporation Agenda  Part one: AMP Overview  Part two: Web applications  Part three: XAMPP Demo

WW Web Production Services North 2 © 2005 IBM Corporation Part three  Setting up an AMP development environment –Installing XAMPP –Starting services –Loading sample data Working with phpMyAdmin –Loading sample code Working with PHP
