The iamp stack (IBM i, Apache, MySQL, PHP) is the IBM i native variant of the LAMP stack it allows for development of web-based applications integrated with the MySQL open source database. iamp is well suited for those customers/environments that wish to leverage existing open source applications based on PHP and MySQL. The iadp stack (IBM i, Apache, DB/2, PHP) is another IBM i native variant of the LAMP stack it allows for development of web-based applications integrated with the DB/2 database and other native IBM i resources iadp is well suited for those customers/environments that wish to develop customized web applications that provide the ability to access and manipulate IBM i resources 2

3 What is the LAMP Stack? LAMP refers to a set of tools (Linux, Apache, MySQL, and PHP) that facilitates rapid development and deployment of software applications LAMP is often defined as the open source web platform. Evolution of web applications Every 7 seconds a new wiki or blog is created Next wave of programmers: folks who create content are now empowered to create applications New platforms being established providing simple, feature rich environments for editing and contributing content. Content is handled with a simple WYSIWYG editor that makes editing accessible to anyone Main content accompanied with discussion tabs, history tabs, version tabs, mailing list tabs 3

4 The LAMP Stack Open Source Software Components used as a "toolkit" by web developers for deploying robust webcontent complete with data access and manipulation Application PHP Has become a major development platform for the enterprise Used by such enterprises as Amazon, Friendster, Google, and Yahoo Apache Linux MySQL What is LAMP? Linux Windows MySQL SQLite PostgreSQL Apache PHP Python Perl Open-source software stack with a strong focus on: Affordability Perceived zero to low cost Ease of development, ease-of-use Community Building solutions. Large body of single-click install & auto-configure solutions and libraries ( L = Linux A = Apache web server M = MySQL P = PHP Perl Python 4

5 The LAMP components Linux Free UNIX-type operating system Has become firmly established as an enterprise-class alternative to proprietary UNIX and Microsoft products Commercial entities, such as IBM, have extended the free Linux kernel and created the support and services infrastructure essential to enterprise customers Apache Traces its roots to the public domain HTTP daemon developed at the National Center for Supercomputing Applications Apache has been the most popular web server every year since 1996 MySQL World's most popular open source database Many large corporations including Sabre Holdings, Cox Communications, The Associate Press, and NASA are using MySQL to power web-sites, businesscritical enterprise applications and packaged software PHP Widely used general-purpose scripting language Especially suited for web development Can be embedded in HTML It has become one of the most popular languages on the web What's driving LAMP (and open-source related development stacks) Constant pressure on developers to do more, faster, and with less as firms strive to reduce costs, improve returns on IT investments, and accelerate time-to-value Growing adoption of SOA environments for enterprise integration Allows wider choice of application development & implementation technologies by allowing heterogeneous systems to interact freely at the service level Faster pace of open source software improvement relative to proprietary products Facilitated by active participation of global user communities Availability of polished developer tools for the LAMP environment Example: Zend's integrated development and production environments for PHP applications 5

6 Speed and Simplicity The language component (PHP) of the LAMP stack (as well as iadp and iamp) has been created specifically to simplify, streamline, and accelerate programming tasks typical of Web development. PHP is particularly well suited for text handling as well as database access for dynamic content generation. PHP features a simple, clear syntax that makes it easy to learn. What can be done with LAMP an Example Wikipedia: >8,000 HTTP requests per second >25,000 SQL requests per second 12 database servers 15 application servers in 'external storage' role 20 application servers in 'object cache' role 6

8 MySQL: World s Most Popular Open Source Database Founded in 1995; operations in 24 countries Adoption of Open Source Over 11,000,000 installations; 65,000 downloads/day Part of a rapidly growing open source LAMP stack Used by IT organizations to implement scale-out architecture More Data & Analysis Community Growth Maturation of Web Architecture Commoditization MySQL Very easy to setup and use Most popular open source database Has gained popularity in the web application world and is used in most of the leading PHP applications. Open Source, but also commercially backed Used in more the 11 million installations Cross-platform (over 20 including IBM i, Windows, Linux, OS/X, HP-UX, AIX, Netware) 8

Tip: Use WRKRDBDIRE to get the database name on the remote i5 ToolKit vs. DB2 Extensions The i5 Toolkit represents functions for accessing native IBM i resources The toolkit is specific to the Zend products for IBM i The toolkit functions can only access local resources (i.e., resources on the same IBM i partition as Zend Core) unless you setup remote connections (such as DDM) outside of the Zend Core environment. All i5 Toolkit functions begin with the characters i5_ The DB2 functions represent an extension to the PHP language The DB2 extensions can access both local and remote DB2 resources through established network connections All DB2 functions begin with the characters db2_ 25
