CloudLinux OS is a Linux distribution specifically designed for shared hosting environments. It is based on the CentOS/RHEL (Red Hat Enterprise Linux) distribution, providing a stable and secure operating system tailored for hosting service providers.
The primary feature of CloudLinux OS is its Lightweight Virtualized Environment (LVE) technology. LVE allows hosting providers to allocate specific resources such as CPU, memory, and I/O to each individual website or user account on a shared server. This ensures that no single account can monopolize server resources, preventing one user’s activities from affecting the performance and stability of others.
Why BoxFly Only Uses CloudLinux OS
Here at BoxFly, we are big fans of CloudLinux OS. Although CloudLinux OS does add a monthly cost to each web hosting server, the features are well worth the cost. Not all web hosting providers will fork up the extra cost for a CloudLinux OS license, it is something to pay attention to when selecting a web host that fits your needs.
Here are the key features that CloudLinux OS includes that make it unique to the web hosting industry:
- LVE Technology: Segregates server resources to ensure fair and stable hosting for multiple users on a single server.
- CageFS: A virtualized file system that encapsulates each user’s files and processes, enhancing security by preventing users from accessing each other’s data.
- Resource Limits: Allows hosting providers to set limits on CPU, memory, and other resources for each user, preventing resource abuse and ensuring consistent performance.
- KernelCare: Provides automated kernel updates without requiring reboots, thus enhancing server security and uptime.
- PHP Selector: Allows users to select their preferred PHP version and modules, enabling compatibility with a wide range of web applications.
- Hardened Kernel: CloudLinux OS includes a hardened kernel with security enhancements to protect against various types of attacks and vulnerabilities.
Overall, CloudLinux OS aims to address the challenges of hosting multiple websites on a single server by offering improved stability, security, and resource allocation, making it a popular choice among web hosting providers.
Bottom Line
CloudLinux OS offers features that free Linux operating systems can’t offer. A lot of web hosting companies will opt for a free operating system to install on their web hosting servers. If the web hosting company is not monitoring their servers like a hawk, they could have one bad customer take down the entire server making your website inoperable. CloudLinux OS offers advanced security features that make it stand out from the rest when selecting an operating system for web hosting servers. While it does come with a monthly cost per server, we think it’s well worth it.
