CloudLinux is a hosting oriented Linux distributive based on CentOS using the LVE (Lightweight virtual environment) kernel technology that is similar to OpenVZ in some aspects or to other OS-based virtualization technologies. CloudLinux is on a mission to make Linux secure, stable, and profitable.
CloudLinux improves the server stability by encapsulating each client in a secure, isolated environment. It means that each user on the server is limited by the number of resources it can use, being placed in a so-called ‘container’ making shared hosting the most common downtime reason is a single account grabbing most of the shared resources due to the heavy site(-s) or unoptimized script(-s).
CloudLinux OS is the leading platform for multitenancy. It improves server stability, density, and security by isolating each tenant and giving them allocated server resources. This creates an environment that feels more like a virtual server than a shared hosting account. By doing so, CloudLinux OS reduces operating costs and churn rates and increases profitability
