CloudLinux OS License

A Server License is a legal permit to install and use specialized software on a server (including a VPS or a Dedicated Server - this license can be for an operating system, management software, or security application...). This not only ensures the legal right to use the software but is also a key factor in ensuring it performs optimally, receives security updates, and gets direct technical support from the developer.

Using licensed software is the fundamental difference between a professional, secure system and one that is unstable and fraught with risks. It is a necessary investment to protect your data and ensure business continuity.

Technical Working Principle

A server license typically operates on automated and continuous authentication mechanisms:

• IP Address Authentication: The license is activated and tied to the main IP address of the server. Any changes to the IP must be updated for the license to remain active.
• Communication with Licensing Servers: The software periodically connects to the developer's servers to verify and confirm the valid status of the license.
• Automatic Updates: With a valid license, the system automatically receives software updates, including bug fixes and security patches, directly from the developer.

Key Benefits of Using a Server License

Using licensed software is not just about legal compliance; it also provides critical technical benefits that help your system run stably and securely:

• Direct Technical Support from the Vendor: When issues arise, you receive the most in-depth and prompt support directly from the experts who developed the software.
• Latest Security Updates & Features: Stay protected from the newest security vulnerabilities and experience enhanced features as soon as they are released.
• Unlock All Premium Features: Activate and use all the powerful functionalities of the software that are restricted in free or non-licensed versions.
• Guaranteed Performance & Stability: The software is guaranteed to operate at the performance and stability levels committed by the developer, free from malware or unauthorized modifications.

Applications and Common Types of Server Licenses

A Server License is typically applied to foundational software that plays a core role in server operation and management:

• Optimized Server Operating Systems: For example, a CloudLinux OS license  enhances stability and isolates resources in a web hosting environment.
• Control Panels: Software like cPanel and DirectAdmin simplifies server and hosting management.
• High-Performance Web Servers: A LiteSpeed Web Server license helps accelerate page load times and improve website capacity.
• Comprehensive Security Software: Solutions such as an Imunify360 license proactively scan for and remove malware, protecting the server from attacks.

CloudLinux OS is a commercial Linux-based operating system designed specifically for shared hosting environments. Its core technology is LVE (Lightweight Virtual Environment), which creates isolated virtual "containers" to partition and limit resources (like CPU, RAM, and I/O) for each account, significantly enhancing the stability and security of the entire server.

By isolating each account, CloudLinux OS has revolutionized the shared hosting industry, transforming a traditionally unstable environment into one that is as secure and reliable as a virtual private server (VPS), while providing maximum flexibility for end-users.

Technical Working Principle

CloudLinux OS operates on three core technologies working in concert:

• LVE (Lightweight Virtual Environment): The "heart" of CloudLinux, this technology creates separate containers to limit resources (CPU, RAM, I/O, Processes) for each account. If one account experiences a surge in usage, it will be throttled rather than crashing the entire server.
• CageFS (Virtualized File System): This creates a virtualized file system ("cage") for each user, completely isolating their data and preventing them from seeing sensitive information or the files of other users on the same server.
• PHP Selector: This allows each hosting account to freely choose its required PHP version (from legacy 5.x to the latest 8.x) and necessary extensions without affecting the server's global configuration.

Key Benefits of CloudLinux OS

Implementing CloudLinux OS on a server provides strategic benefits for both providers and end-users:

• Enhanced Stability & "Noisy Neighbor" Prevention: LVE completely solves the issue of one website using too many resources and impacting others. Each account is guaranteed its share of resources, ensuring consistent website performance.
• Superior Security & Absolute Isolation: CageFS effectively prevents privilege escalation and local attacks, two of the most common forms of attacks in shared hosting environments.
• Flexible PHP Version Selection: Users have full control to choose the most suitable PHP version for their website's source code, ensuring compatibility and allowing the use of the latest technologies.
• Optimized Performance & Server Density: Allows hosting providers to serve more customers on a single server safely and reliably, which in turn helps reduce the cost of the service.

Applications and Use Cases

CloudLinux OS is an essential solution for multi-user server environments, especially:

• Shared Hosting Providers: This is the primary audience. CloudLinux helps increase customer density per server, reduce support tickets, and improve service quality.
• Developers & Hosting Resellers: It provides a flexible and secure environment for their clients, allowing for easy customization of the PHP environment.
• Schools & Educational Organizations: Creates secure and isolated hosting environments for students or different departments on the same infrastructure.
• Any Server with Multiple Websites: Any server hosting multiple websites from different users should use CloudLinux to ensure stability and security.

• Advanced Web Application Firewall (WAF): Uses AI to analyze and block common attacks like SQL injection, XSS, and brute-force right at the initial access layer.
• Intrusion Detection & Prevention System (IDS/IPS): Monitors and analyzes server logs in real-time to detect suspicious behavior and automatically block violating IP addresses.
• Malware Scanner: Automatically scans the system to find and remove malicious files. With a continuously updated database, it can even identify previously unknown "zero-day" threats.
• Proactive Defense: Prevents malicious PHP scripts from executing by analyzing their behavior, even if the malware is not yet in any identification database.
• Reputation Management: Proactively blocks access from IP addresses that are globally identified as sources of attacks, stopping threats before they even reach the server.

Key Benefits of Imunify360

Equipping your server with Imunify360 provides security and numerous outstanding benefits:

If you are managing a VPS or a Dedicated Server, especially for hosting reselling or hosting multiple websites, installing CloudLinux OS is one of the most worthwhile upgrades. It transforms your server into a professional, more stable, and secure hosting platform.

Turn Your Server into a Professional Shared Hosting Platform

LVE (Lightweight Virtual Environment) technology is the "heart" of CloudLinux OS. It allows you to precisely partition and limit resources (CPU, RAM, I/O, Processes) for each hosting account. This ensures that a single user cannot monopolize resources and affect other users, providing absolute stability for your service.

Isolate Users & Completely Prevent Local Attacks

On standard operating systems, if one website on the server is compromised, an attacker can escalate privileges to attack other websites (a local attack). CloudLinux OS completely solves this with CageFS, a virtualized file system that "cages" each user in their own environment, making it impossible for them to see or access other users' data.

Increase Revenue and Business Efficiency

• Increase Client Density: Thanks to the stability, you can confidently place more hosting accounts on a single server without fear of overload, optimizing hardware costs.
• Reduce Support Tickets: When the server is stable and users do not affect each other, the number of performance-related support tickets decreases significantly.
• Enhance Customer Satisfaction: A stable and secure service is key to retaining customers and building a reputable brand.

In summary, CloudLinux OS is a necessary investment to elevate your hosting service. As an official CloudLinux partner in Vietnam, VietHosting provides CloudLinux OS licenses at the best prices, along with free initial installation support, to help you deploy this technology quickly and effectively.

Yes, please send an email or ticket, and we will assist you with installing CloudLinux OS completely free of charge.

However, the server must first have a compatible operating system installed and configured according to CloudLinux OS requirements.

Unfortunately, VietHosting does not apply a refund policy for server software license fees, including cPanel, DirectAdmin, CloudLinux OS, Imunify360, and LiteSpeed, once the service has been activated.

Why is this the policy?

This policy is based on the operating principles of third-party software vendors. When you register, VietHosting pays the license fee on your behalf to the provider, CloudLinux, for the entire cycle. This fee is non-refundable from CloudLinux once the license is activated. Therefore, we cannot issue a refund for this cost.

How do I stop the service renewal?

Although a refund is not possible for an activated cycle, you have the full right to cancel the service renewal for the next cycle. To avoid unwanted charges, you must submit a cancellation request with the 'End of Billing Cycle' option through the client area at least 7 days before the service's expiration date.

For more details, please refer to our full Refund Policy.

cPanel is a leading commercial web hosting control panel for Linux servers. It provides an intuitive graphical interface combined with powerful automation tools to simplify the comprehensive administration of a hosting account, including the management of files, databases, emails, domains, and security settings.

With its user-friendly interface and rich feature ecosystem, cPanel has become the "gold standard" in the hosting industry, making server management easier than ever for all types of users.

Technical Working Principle
