CloudLinux: Reliability and Efficiency in Hosting


1. The core strength of CloudLinux

The main strength of CloudLinux comes from its ability to isolate each user account in a separate container, which prevents different accounts on the same server from influencing each other. This isolation ensures that issues related to the security or resources of one account will not affect the others. Also, CloudLinux allows ISPs to control and limit resource usage by each account, thereby maintaining high server stability and performance.

2. Additional advantage of CloudLinux

An additional advantage of CloudLinux is flexible PHP version management, which allows users to choose and switch between different PHP versions for compatibility with a variety of applications and scripts. This is extremely important in the dynamically developing world of web technologies.


3. Why CloudLinux was created

CloudLinux is designed to be compatible with popular hosting panels such as cPanel and Plesk, making integration and management easier for hosting providers. It offers hosting companies the opportunity to improve the quality of their services while reducing risks and increasing the satisfaction of their customers.

The main features and benefits of CloudLinux

Lightweight Virtual Environment

1. Isolation of Resources

CloudLinux uses a technology called Lightweight Virtual Environment (LVE) to isolate each hosting account in its own container. This isolation ensures that problems in one account do not affect other accounts on the same server, thereby reducing the risk of excessive resource strain from one account and improving overall server stability.


2. Resource Management

CloudLinux allows hosting providers to set limits on CPU usage, memory, I/O operations, and other resources at the account level, which helps prevent shared resource issues.


3. Compatibility with Popular Control Panels

CloudLinux is compatible with most popular hosting control panels such as cPanel, Plesk and DirectAdmin, making integration and management easier for hosting providers.


4. KernelCare

CloudLinux includes KernelCare, a tool to automatically update the Linux kernel without requiring a server restart. This helps maintain server security and stability.

CloudLinux improves security by isolating each hosting account in a separate container (LVE). This limits the possibility of one account affecting other accounts on the same server. Also, features like CageFS prevent various types of attacks by providing file system isolation.


CloudLinux allows hosting providers to set specific resource limits (such as CPU, memory, I/O) for each account. This prevents scenarios where one account overuses resources, which can affect other accounts on the same server.


CloudLinux supports multiple versions of PHP, allowing users to choose and switch between different versions according to the needs of their websites. This is especially useful for maintaining compatibility with older applications that require certain versions of PHP.


CloudLinux improves overall server performance by ensuring that resources are allocated in a fair and efficient manner. Resource isolation prevents problems that commonly occur in shared environments, such as server overload from a single user.


There are three operating systems in the Cloudlinux OS product line:

    • - CloudLinux OS Shared – improves the stability, density and security of a shared server by isolating each client and giving it distributed server resources.
    • - CloudLinux OS Shared Pro – is an enhanced version of CloudLinux OS Shared that includes in-depth performance analysis and centralized monitoring tools.
    • - CloudLinux OS Solo – for small businesses and each individual with only one hosting account. It includes website monitoring, performance detection and performance optimization tools to make sure a website is up and running, help investigate WordPress, PHP, database issues and speed up a website.
    • - CloudLinux OS Admin is a specialized version of CloudLinux OS designed for hosting providers with VPS or dedicated servers. It allows easy migration from shared hosting, supports up to 5 users and offers enhanced security through technologies such as LVE, CageFS, HardenedPHP and SecureLinks. In addition, CloudLinux OS Admin simplifies server management and increases performance with tools such as PHP Selector, Mod_lsapi PRO, PHP X-Ray and AccelerateWP, but does not include NodeJS, Python and Ruby selectors and DB Governor.

KernelCare included in CloudLinux is a tool to automatically update the Linux kernel without the need to restart the server. This has several key benefits:

1. Business Continuity: Allows security patches and kernel updates to be deployed live without causing server downtime or requiring reboot.

2. Improved security: Rapid application of security patches significantly reduces the time a system is vulnerable to known kernel vulnerabilities.

3. Saving time and resources: Automatic updating reduces the need for manual patch management and scheduling server restarts, which saves time and effort for IT teams.

KernelCare provides significant benefits in security and server management, which is essential for businesses using CloudLinux.


No, you do not need to restart your server for kernel updates if you are using CloudLinux with KernelCare. KernelCare allows Linux kernel updates to be performed "live" without the need to reboot the server. This means you can apply security patches and update the kernel while keeping your server up and running without service interruptions.
