Cloudlinux

CloudLinux is a Linux-based operating system built to give web hosting providers a more stable and secure platform. It lets system administrators allocate and cap resources per user account, so one account's usage does not affect other accounts on the same server. CloudLinux also provides advanced security features such as LVE, CageFS, and MySQL Governor to isolate and protect accounts from external and internal attacks.

CloudLinux offers notable features such as:
- LVE technology (Lightweight Virtual Environment) allows CPU, RAM, I/O and network resources to be allocated to each hosting account, preventing server overload caused by a single account consuming too many resources.
- CageFS technology (Caged File System) creates a separate space for each hosting account, protecting that account's data and configuration from interference by other accounts on the same server.
- MySQL Governor technology monitors and limits MySQL usage in a shared hosting environment. It uses per-thread MySQL resource usage statistics and LVE limits to control the CPU and I/O consumption of MySQL users.
- PHP Selector technology allows the PHP version and extensions to be selected per hosting account, improving the flexibility and compatibility of web applications.
- Node.js Selector and Python Selector technology allows the Node.js and Python versions to be selected per hosting account, supporting web applications written in these languages.
- KernelCare technology allows the kernel to be updated without restarting the server, reducing downtime and improving system safety.

CloudLinux mod_lsapi PRO is a technology developed by CloudLinux for running PHP on the Apache web server. It improves the performance, security, and stability of PHP applications by using the LiteSpeed API to communicate with Apache. CloudLinux mod_lsapi PRO also supports advanced features such as PHP Selector, OPcache, Memcached, and Redis.

CloudLinux SecureLinks is a security feature of the CloudLinux operating system that blocks attacks carried out through symlinks and hard links. Symlinks and hard links are references to other files or directories on the system. Attackers can abuse them to read or modify sensitive files belonging to other users on the same server. SecureLinks checks and blocks invalid symlinks and hard links, keeping hosting accounts secure.

The CloudLinux Slow Site Analyzer is a performance-analysis tool for websites running on the CloudLinux operating system. It helps users identify what's slowing a site down — system resources, code, the database, or plugins — and provides recommendations to improve page-load speed and the user experience.

CloudLinux PHP X-Ray is a performance monitoring tool for PHP-based web applications, particularly content management systems such as WordPress, Joomla and Drupal. PHP X-Ray helps you find and fix problems with page load speed, server resource usage, and faults in your code or plugins. Using PHP X-Ray requires CloudLinux OS Pro and cPanel. You enable it for a website by entering the URL into the search box in the PHP X-Ray section of cPanel. You then receive a detailed report on the factors affecting your site's performance, such as PHP function execution times, the number of MySQL queries, and the load time of static files. PHP X-Ray is a practical tool for improving user experience and optimizing your website.

CloudLinux Accelerate WordPress is a WordPress optimization toolkit developed by CloudLinux, a company that provides a Linux-based operating system for cloud computing. The toolkit lets hosting providers and website owners improve the performance, security, operation and profitability of WordPress sites. CloudLinux Accelerate WordPress includes features such as:
- Faster page load times using techniques such as minification, compression, caching, lazy loading, CDN and so on.
Lower server resource usage with LVE (Lightweight Virtual Environment), a CloudLinux feature that isolates and caps the resources available to each website.
- Protects websites from attacks and malware by using CageFS, CloudLinux's virtualized file system, to enclose each website in a separate, secure environment.
- Easy website management using a straightforward administration interface and integration with popular WordPress plugins.
Cloudlinux Accelerate Wordpress is an effective, cost-efficient solution for anyone using Wordpress to build websites for a range of purposes. You can find out more about this toolset on the official Cloudlinux website.
