CloudLinux

CloudLinux OS is a commercial Linux distribution tailored for shared hosting environments. Developed by CloudLinux, Inc., it enhances server stability, security, and performance by isolating each tenant and allocating specific server resources.

A key feature of CloudLinux OS is the Lightweight Virtual Environment (LVE), which allows administrators to set resource limits per user, preventing any single tenant from monopolizing server resources. This ensures consistent performance and reduces the risk of server downtime.

Security is further bolstered through CageFS, a virtualized per-user file system that encapsulates each customer, preventing users from seeing each other and accessing sensitive information. Additionally, HardenedPHP secures old and unsupported versions of PHP, addressing vulnerabilities in versions no longer maintained by the PHP.net community.

CloudLinux OS also offers flexibility with its PHP Selector, allowing end-users to choose the specific PHP version and extensions they need. This adaptability is crucial for hosting providers managing diverse client requirements.

In summary, CloudLinux OS provides a robust solution for shared hosting providers, delivering enhanced stability, security, and performance through user isolation and efficient resource management.
