CloudLinux

Resource usage limitation ресурсов системы

CloudLinux OS is designed for shared hosting providers. It isolates each customer into a separate “Lightweight Virtualized Environment” (LVE), which partitions, allocates, and limits server resources, like memory, CPU, and connections, for each tenant.

Accounts separation

CloudLinux OS also “cages” tenants from one another to avoid security breaches. This way, unstable scripts or malware are not able to sprawl across your customer sites, causing severe harm.

PHP Selector

The PHP Selector allows end users to select the specific version of PHP they need. It allows ultimate flexibility by offering all popular versions of PHP, with more than 120 PHP extensions to choose from.

MySQL Governor

MySQL Governor tracks CPU and disk IO usage for every user in real time and throttles MySQL queries by using same-per-user LVE limits. By using the dbtop utility, it is possible to see usage as it happens on a per-customer basis, ensuring that system admins always know what is going on.

Mod_lsapi

Mod_lsapi is the fastest and most reliable way to serve PHP pages. It is a drop-in replacement for SuPHP, FCGID, RUID2, and ITK. It has a low memory footprint and understands PHP directives from .htaccess files.
