LAMP (Linux, Apache, MySQL, PHP/Perl/Python) may be a quite common example of a web service stack, named as an acronym of the names of its original four open-source components: the Linux operating system, the Apache communications protocol Server, the MySQL relational management system (RDBMS), and the PHP programming language. The LAMP elements ar mostly interchangeable and not restricted to the initial choice. As an answer stack, LAMP is appropriate for building dynamic net sites and web applications.
With the growing use of the prototypic LAMP, variations and retronyms appeared for alternative mixtures of software system, web server, database, and code language. as an example, constant installation on the Microsoft Windows operating system family is thought as WAMP. another running IIS in place of Apache is called WIMP. Variants involving alternative operative systems include MAMP (macOS), SAMP (Solaris), FAMP (FreeBSD), iAMP (iSeries) and XAMPP (cross-platform).
Specific solutions ar needed for websites that serve giant numbers of requests, or give services that demand high uptime. High-availability approaches for the LAMP stack could involve multiple net and information servers, combined with further elements that perform logical aggregation of resources provided by every of the servers, likewise as distribution of the employment across multiple servers. The aggregation of net servers could also be provided by inserting a load balancer in front of them, as an example by using Linux Virtual Server (LVS). For the aggregation of information servers, MySQL provides internal replication mechanisms that implement a master/slave relationship between the initial information (master) and its copies (slaves).
