TRANSCRIPT
MotivaitonBasic Web Systems with Delivery of Static and
Dynamic Web Pages
html, css, media
javascript (“dynamic”on client ---this is not the sameas dynamic used here for dynamic website)
php, java, python,ruby, .net, nodeJS, …
Dynamic Web –MANY possibilitiesBASIC POSSIBILITIES (here featuring
opensource /free solutions)
LAMP = Linux, Apache, MySQL, and PHP WAMP = Windows, Apache, MySQL, and PHP MAMP = Mac, Apache, MySQL, and PHP
Dynamic Web- MANY possibilities1. JavaScript
Client-side scripting access to elements of HTML document
Perform data handling and web server requests in background
2. PHPServer-side scripting Open source, simplicity and built-in links to MySQL database
3. MySQLOpen-source Relational Databases that supports
structured queries and is free to use and install on web servers
4. Apache ServerOpen source server software that serves up HTML, media
files etc PHP handles main work on web server, MySQL manages data, and JavaScript looks after web page presentation. JavaScript
can also talk with your PHP code on the web server whenever it needs to update something (either on the server or on the web page).
Dynamic Web, AJAX and Web 2.0
JavaScript specifies web page interactivity and presentation
PHP handles main work on web server and retrieves data
MySQL manages and stores data JavaScript performs data handling & server
requests in background JavaScript can also talk with PHP code on the
web server to update data or presentation (either on server or web page)
JavaScript used for AJAX and Web 2.0
“Asynchronous JavaScript and XML” Ajax is the main process behind what is now known as Web 2.0 Process of accessing the web server in the background
Why NOT LAMPBut management is a hassle:
Configuration, tuning Backup and recovery, disk space management Hardware failures, system crashes Software updates, security patches Log rotation, cron jobs, and much more
SCALABILITY ISSUES this leads to CS6320 class and discussion of Web Systems (distributed, cloud, etc)
SPEED/CAPABILITIES is Php the best choice for server side programming?
Facebook used to be the largest LAMP based company but, things are changing.
Things changing---consider the “simple” web serverHere Apache is no longer the CLEAR winner
(from July 2013) –Nginx (“engine-x”) ….Apache

Server Side and Us??PhP – scripting, easy to learn?, not much
configurationFacebook in beginning days was only php, not
anymore (issues in scalability, performance)Java – more configuration,
Sam’s Club, Amazon and Apple App Store use Java-based web frameworks.
Ruby – less configuration, more conventionScriptingMVC focusedScribd, Hulu and Twitter all use Ruby.
To consider: Python, NodeJS, ….
