DirectAdmin 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.

DirectAdmin is a popular commercial web hosting control panel used to manage Linux servers. It provides an intuitive graphical interface that allows users to manage server services without needing to use complex command lines.

• Reseller: The intermediate level, allowing hosting resellers to create and manage their own resource packages and the User accounts under their ownership.
• User: The basic level, designed for website owners to manage the resources within their hosting package, such as files, emails, databases, etc.

Key Benefits of DirectAdmin

Compared to other alternatives, DirectAdmin is often favored by users who prioritize performance and simplicity:

• High Performance & Resource Efficiency: DirectAdmin is designed to be extremely lightweight, consuming less CPU and RAM, which frees up server resources to handle other tasks.
• Minimalist Interface & Superior Speed: The interface is focused on core features without unnecessary clutter, helping users perform administrative tasks quickly and easily.
• Cost-Effective Licensing: With a significantly lower license fee than its competitors, DirectAdmin helps reduce the cost of hosting packages, providing economic benefits to the end-user.

The KVM VPS and Dedicated Servers at VietHosting support the installation of all the popular operating systems mentioned above, giving you the flexibility to choose the most suitable platform for DirectAdmin.

Both cPanel and DirectAdmin are leading control panels, but recent changes in pricing policies have made the comparison more critical than ever. The choice is no longer based on habit, but on your actual priorities regarding performance, cost, and ecosystem.

To help you make the best choice, let's analyze the core differences in the comparison table below.

Criteria	cPanel	DirectAdmin
Performance & Resources	Consumes more resources due to its extensive features and background services.	Superior. Lightweight and consumes less RAM/CPU, helping the server run faster.

Interface & Experience	Very friendly, familiar, and extremely easy to use for beginners.	The modern Evolution skin is clean and highly customizable, favored by experienced users.
Ecosystem & Extensibility	Massive ecosystem with countless third-party plugins and apps (Softaculous, JetBackup, etc.).	A smaller ecosystem, but still includes all popular and necessary plugins.

Conclusion: When to Choose Which Type?

• You SHOULD choose cPanel when: You are a beginner, prioritize ease of use and familiarity, need a vast plugin ecosystem for extensibility, and budget is not a major concern.
• You SHOULD choose DirectAdmin when: You prioritize high performance and server resource savings, want to maximize cost control, or need to host a large number of websites on a single server.

LiteSpeed Web Server (LSWS) is a high-performance web server software, renowned for its ability to accelerate websites and efficiently handle a large number of concurrent connections. Designed as a direct replacement for Apache, LSWS uses a unique event-driven architecture that minimizes system resource consumption (CPU, RAM), delivering superior performance and stability.

With its built-in LSCache engine, LiteSpeed has become the top choice for WordPress websites and other open-source platforms, significantly improving user experience and SEO scores.

Technical Working Principle

The power of LiteSpeed comes from its modern and distinct architectural principles:

• Event-Driven Architecture: Unlike Apache, which creates a new process for each connection, LiteSpeed uses a few processes to handle thousands of connections simultaneously. This saves resources and eliminates bottlenecks during high-traffic periods.
• Deeply Integrated LSCache: LiteSpeed comes with an extremely powerful server-level cache engine built-in. LSCache can communicate directly with popular applications (WordPress, Magento, Joomla, etc.) to store and serve pre-built pages, minimizing processing time.
• Full Apache Compatibility: LiteSpeed is designed to read and work with Apache's configuration files (like .htaccess). This makes migrating from Apache to LiteSpeed seamless, without requiring any configuration changes on the website's end.

Key Benefits of LiteSpeed Web Server

Upgrading to LiteSpeed provides outstanding and measurable benefits:

• Superior Page Load Speed: Thanks to its extremely fast PHP and static content processing, LiteSpeed significantly reduces page load times, directly improving user experience.
• High Concurrency Capacity: The event-driven architecture allows the server to handle a large number of concurrent users without becoming overloaded, ideal for websites with fluctuating traffic.
• Web Application Acceleration (LSCache): With the LSCache plugin, WordPress websites can achieve incredible speeds, optimize Core Web Vitals scores, and improve Google rankings.
• Advanced Integrated Security: LiteSpeed has built-in security rules to defend against common DDoS attacks and is fully compatible with mod_security, creating a robust defense layer for your website.

Applications and Use Cases

LiteSpeed Web Server is the ideal performance upgrade for most types of websites, especially:

• WordPress & WooCommerce Websites: This is the most popular and effective use case, where the LSCache plugin unleashes its full power.
• High-Traffic Websites: News sites, forums, or large e-commerce stores that need to handle many concurrent connections stably.
• Hosting Service Providers: Using LiteSpeed to offer a faster, more stable hosting service that can serve more customers on the same server.
• All Websites Using Apache: Anyone currently using Apache who wants to improve performance without having to reconfigure their entire system.

Why purchase a LiteSpeed License from VietHosting?

Choosing VietHosting to equip your server with LiteSpeed is a smart investment decision:

• Official & Trusted Partner: As an authorized partner of LiteSpeed in Vietnam, we guarantee valid licenses with the best support.
• Competitive Pricing & Fast Activation: We offer cheap LiteSpeed licenses with flexible plans and a fast, automated activation system.
• Pre-integrated in Hosting Services: All Hosting packages at VietHosting come equipped with LiteSpeed Web Server, delivering maximum performance and speed.
• Installation & Optimization Support: With over 16 years of experience, our technical team is ready to help you install, configure, and optimize LiteSpeed to achieve the highest performance.

Upgrading to LiteSpeed is the most effective solution to accelerate your website and outperform competitors. Purchase a LiteSpeed license from VietHosting today to deliver a brand-new speed experience to your users.

To experience the power of LiteSpeed immediately without managing a server yourself, you can explore our cPanel Hosting and DirectAdmin Hosting packages. All are built on a platform that combines leading technologies: LiteSpeed Web Server (for speed), CloudLinux OS (for stability), and Imunify360 (for security), offering you a comprehensive solution.

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.

Why purchase a CloudLinux OS License from VietHosting?

Choosing VietHosting to equip your server with CloudLinux OS is a smart decision:

• Official & Trusted Partner: As an authorized partner of CloudLinux in Vietnam, we guarantee valid licenses with the best support.
• Competitive Pricing & Fast Activation: We offer cheap CloudLinux OS licenses and a fast, automated activation system.
• Pre-integrated in Hosting Services: All cPanel Hosting and DirectAdmin Hosting packages at VietHosting come equipped with CloudLinux OS at no extra cost.

Imunify360 is a comprehensive security solution designed specifically for web servers running the Linux operating system. It combines a multi-layered defense system—including a Web Application Firewall (WAF), malware scanning, and an intrusion detection system—with Artificial Intelligence (AI) and Machine Learning. This combination allows Imunify360 to proactively and automatically detect, prevent, and handle cybersecurity threats.

In the context of increasingly sophisticated cyber attacks, Imunify360 acts as an intelligent bodyguard, working tirelessly 24/7 to protect your digital assets, even while you sleep.

Technical Working Principle: Multi-layered Defense

Imunify360 protects your server through a sophisticated, multi-layered defense system that operates concurrently:

• 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:

• Comprehensive 360-degree Protection: Instead of installing multiple separate tools, Imunify360 offers an "all-in-one" solution, protecting your server from most of today's common attack types.
• Proactive & Automated Defense: Thanks to AI and Machine Learning, Imunify360 can automatically detect and neutralize new threats without human intervention, protecting your system 24/7.
• Minimizes Risks & Damages: Timely prevention of attacks helps protect sensitive data, maintain brand reputation, and avoid financial losses from website downtime or information theft.
• Peace of Mind & Time Savings: The automated system saves server administrators time and effort in monitoring and responding to security issues.

Applications and Use Cases

Imunify360 is the ideal security solution for any web server based on the Linux platform, especially:

• Hosting Service Providers: Helps protect all customers on a shared hosting server, minimizing the risk of cross-contamination and improving service quality.
• Corporate & Personal Web Servers: Protects critical websites and e-commerce stores from data theft and sabotage attacks.
• WordPress & Open-Source Websites: These platforms are often targets of automated attacks. Imunify360 provides a robust layer of protection against common vulnerabilities.
• Any Linux Server Needing Security: Anyone operating a Linux server who wants a powerful, automated, and easy-to-manage security solution.

Why choose Imunify360 from VietHosting?

Choosing VietHosting to protect your server with Imunify360 is a wise decision:

To be comprehensively protected from the start without worrying about installation or management, consider our cPanel Hosting and DirectAdmin Hosting services. These are comprehensive hosting solutions where we combine leading technologies to deliver the best experience: Imunify360 (for security), LiteSpeed Web Server (for speed), and CloudLinux OS (for stability).

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, DirectAdmin, for the entire cycle. This fee is non-refundable from DirectAdmin 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.
