The LAPP stack includes Linux, Apache, PostgreSQL (instead of MySQL), PHP, Python, and Perl.
TurnKey LAPP is a server appliance that just works, with no configuration required. It gets you up and running with LAPP Web stack in minutes on a virtual machine, bare metal or in the cloud. It's designed to be easy to use and easy to maintain. Security patches are automatically installed. It provides a Web management interface, configuration console, and AJAX Web shell. To minimize its footprint, the appliance is built from the ground up with the minimum required components. It runs everywhere thanks to multiple build formats, including an installable live CD, a VMDK with OVF support, and an Amazon EC2 AMI. It's a part of the TurnKey Linux Virtual Appliance Library.
