LAMP

Linux, Apache, MySQL/MariaDB, PHP/Perl/Python

LAMP is an acronym denoting one of the most common software stacks for many of the web's most popular applications. However, LAMP now refers to a generic software stack model and its components are largely interchangeable

• Linux operating system
• Apache HTTP Server
• MySQL (or MariaDB) relational database system
• PHP (or Perl, or Python) programming language

Common variations

• WAMP - Windows instead of Linux
• WIMP - Windows running Microsoft's IIS in place of Linux and Apache
• MAMP - MacOS in place of Linux
• LEMP - Nginx in place of Apache
• LAPP - with PostgreSQL in place of MySQL

More recently compatible variations are typically described as LAMP stacks or LAMP-like stacks, even if the individual components don't match the acronym.
