The LEMP Stack is a popular software stack used for web development. It consists of four main components: Linux, the operating system; Nginx, a high-performance web server; MySQL or MariaDB, the database management system; and PHP, a programming language for server-side scripting. Together, these technologies enable developers to build and manage dynamic websites and applications. The name "LEMP" is derived from the pronunciation of "Nginx" (engine-x). This stack is known for its speed and efficiency, making it a preferred choice for many developers. By using the LEMP Stack, developers can create robust web applications that can handle high traffic and provide a seamless user experience.
