LAMP (Linux, Apache, MySQL, PHP) stack under the hood: A brief walk through the LAMP components and the various stacks available. A drill down into optimizing the Kaltura LAMP environment focusing on optimizing PHP and little touch of MySQL and Apache options with emphasis on security where applicable. Many people develop in PHP without giving much consideration to optimizing their environments to get the maximum performance gain. This session will take you through a beginner's walkabout on this rather broad topic in the hope that you'll later be able to research further and make custom improvements to your Kaltura stack.
