LAMP (Linux, Apache, MySQL/MariaDB, PHP) is a popular stack for hosting dynamic web applications on Linux-based systems like Debian 11. Apache serves as the web server, while MySQL or MariaDB manage the databases, and PHP handles server-side scripting. Debian 11 makes it easy to install and configure each component through its package manager. LAMP is highly customizable, reliable, and widely used for both small and large-scale web applications. It offers a solid foundation for developers to build, deploy, and manage websites efficiently.
