LAMP is a shorthand term for a web application platform consisting of Linux, Apache, MySQL and one of Perl or PHP. Together, these open source tools provide a world-class platform for deploying web applications. Running on the Linux operating system, the Apache web server, the MySQL database and the programming languages, PHP or Perl deliver all of the components needed to build secure scalable dynamic websites. LAMP has been touted as “the killer app” of the open source world.
With many LAMP sites running Ebusiness logic and Ecommerce site and requiring 24x7 uptime, ensuring the highest levels of data and application availability is critical. For organizations that have taken advantage of LAMP, these levels of availability are ensured by providing constant monitoring of the end-to-end application stack and immediate recovery of any failed solution components. Some also supports the movement of LAMP components among servers to remove the need for downtime associated with planned system maintenance.
The paper gives an overview of LINUX, APACHE, MYSQL, and mainly on PHP and its advantage over other active generation tools for interactive web design and its interface with the advanced database like MYSQL and finally the conclusion is provided.
One of the great "secrets" of almost all websites (aside from those that publish static .html pages) is that behind the scenes, the webserver is actually just one part of a two or three tiered application server system. In the open source world, this explains the tremendous popularity of the Linux-Apache-MySQL-PHP (LAMP) environment. LAMP provides developers with a traditional two tiered application development platform. There is a database, and a "smart" webserver able to communicate with the database. Clients only talk to the webserver, while the web server transparently talks to the database when required. The following diagram illustrates how a typical LAMP server works.
By combining these tools you can rapidly develop and deliver applications. Each of these tools is the best in its class and a wealth of information is available for the beginner. Because LAMP is easy to get started with yet capable of delivering enterprise scale applications the LAMP software model just might be the way to go for your next, or your first application. Let’ take a look at the parts of the system.
LINUX is presently the most commonly used implementation of UNIX. Built from the ground up as a UNIX work-alike operating system for the Intel 386/486/pentium family of chips by a volunteer team of coders on the internet LINUX has revitalized the old-school UNIX community and added many new converts. LINUX development is led by Linus Torvalds. The core of the system is the LINUX kernel. On top of the kernel a LINUX distribution will usually utilize many tools from the Free Software Foundation’s GNU project and implimentation. LINUX has gained a huge amount of momentum and support, both from individuals and large corporations such as IBM. LINUX provides a standards compliant robust operating system that inherits the UNIX legacy for security and stability. Originally developed for intel x86 systems LINUX has been ported to small embedded systems on one end of the spectrum on up to large mainframes and clusters. LINUX can run on most common hardware platforms.
Apache is the most popular web server on the Internet. Apache like LINUX, MySQL and PHP is an open source project and implimentation. Apache is based on the NCSA (National Center for Super Computing Applications) web server. In 1995-1996 a group of developers coalesced around a collection of patches to the original NCSA web server. This group evolved into the Apache Software foundation. With the release of Apache 2.0 apache has become a robust well documented multi-threaded web server. Particularly appealing in the 2.0 release is improved support for non-UNIX systems. Apache can run on a large number of hardware and software platforms. Since 1996 Apache has been the most popular web server on the Internet. Presently apache holds 67% of the market.
MySQL is a fast flexible Relational Database. MySQL is the most widely used Relational Database Management System in the world with over 4 million instances in use. MySQL is high-performance, robust, multi-threaded and multi user. MySQL utilizes a client server architecture. Today, more than 4 million web sites create, use, and deploy MySQL-based applications. MySQL’ focus is on stability and speed. Support for all aspects of the SQL standard that do not conflict with the performance goals are supported.
Features include:
 Portability. Support for a wided variety of Operating Systems and hardware
 Speed and Reliability
 Ease of Use
 Multi user support
 Scalability
 Standards Compliant
 Replication
 Low TCO (total cost of ownership)
 Quality Documentation
 Dual license (free and non-free)
 Full Text searching
 Support for transactions
 Wide application support
What's next in the field of web design? It's already here. Today's webmasters are deluged with available technologies to incorporate into their designs. The ability to learn everything is fast becoming an impossibility. So your choice in design technologies becomes increasingly important if you don't want to be the last man standing and left behind when everyone else has moved on. But before we get to that, lets do a quick review of the previous generation of web design.
