CloudLinux Overview
What is CloudLinux CloudLinux is a proven solution for shared hosting providers that: Improves server s stability and security Increases density Improves performance Decreases support costs Prevents churn
Compatibility CloudLinux works with all major control panels and is compatible with most software commonly used with CentOS and RHEL.
Components LVE Manager MySQL Governor CageFS SecureLinks PHP Selector Ruby Selector Python Selector OptimumCache (beta) mod_lsapi (beta)
LVE Manager CloudLinux utilizes a kernel level technology to set resource limits per tenant. This ensures a tenant can never use more than the resources given to them. Gives full control over: CPU Memory IO Concurrent Connections Number of Processes Inodes (only for cpanel) Prevents traffic spikes and bad neighbor effect
Historical Info CloudLinux gives you exact information on how much resources each customer consumes, allowing to detect heavy users, and upgrade them to more expensive packages KNOW EXACT USAGE PER CUSTOMER
Live Indicators Customer is provided with exact information on how much resources they are using right now, as well as historically
MySQL Governor MySQL Governor is a set of utilities to monitor and operate MySQL usage in a shared hosting environment The monitoring is done via resource usage statistics per each MySQL thread New MySQL Governor tracks exact CPU and IO usage as it happens With such real-time statistics, you can instantly detect abusers and throttle them
CageFS CageFS is a virtualized file system and a set of tools to lock each user in its own 'cage'. CageFS has many valuable benefits, such as: Only safe binaries are available to user User will not see any other users, and would have no way to detect presence of other users & their user names on the server User will not be able to see server configuration files, such as Apache config files User will have limited view of /proc file system, and will not be able to see other user s processes

PHP Selector Allows end users to select PHP versions 4.4, 5.1, 5.2, 5.3, 5.4, 5.5 and 5.6 Allows to choose from more than 120 PHP extensions UI to manage php.ini settings
Ruby Selector The Ruby Selector allows end users to choose the Ruby version for application and to install additional modules (gems) to the application environment. Ruby Selector uses mod_passenger for optimum performance. Ruby Selector Benefits: Supports 1.8, 1.9, 2.0, and 2.1 Ruby versions Allows users to install additional modules to application environments
Python Selector Python Selector allows end users to choose the Python version as an application and to install additional modules. Python Selector uses mod_passenger to get the best performance from Python applications.
SecureLinks SecureLinks is a kernel-level technology that prevents all known symbolic link attacks, which enhances the security level of the servers even further.
OptimumCache (beta) OptimumCache creates a cache of duplicate files (WordPress, Joomla and other popular software). All duplicates get loaded from a singular copy of the file, creating only one instance in system cache. System bypasses disk IO for duplicates, significantly improving the speed of reading that file, decreases memory foot print, while lowering load on the hard disk. OPTIMUMCACHE CAN DOUBLE IO THROUGHPUT
mod_lsapi (beta) New way to serve PHP from Apache Faster then mod_php, FCGID and PHP-FPM Lower memory footprint opcache compatible PHP Selector compatible php options in.htaccess
