A Stack of Open Source Software
A company called SourceLabs is shipping the AMP Stack, a hardened distribution of Apache, MySQL and PHP (AMP). While anyone can download Apache, MySQL and PHP from their respective sources, SourceLabs has worked to test the applications together for performance and security issues. The Stack includes Apache 1.3.33, PHP 5.0.3 and MySQL 4.1.9. InformationWeek also has coverage of SourceLabs and the AMP Stack.
