In the ever-evolving world of web hosting, web hosts and website owners must prioritize solid performance, strong security, and reliable stability. While shared environments are affordable, they often deal with resource allocation, security exploits, and performance issues.
CloudLinux OS Shared Pro is a revolutionary product designed and built for shared hosting environments that significantly improves security, stability, and density. It helps hosting providers deliver better quality of service to customers by isolating all users from each other and preventing resources from being abused, which limits vulnerabilities and strengthens security protocols.
What is CloudLinux OS Shared Pro?
CloudLinux OS Shared Pro is an advanced operating system for shared hosting environments. It is one step beyond CloudLinux OS Shared, adding new features that enhance server performance, security, and usability.
The CloudLinux OS Shared Pro has sophisticated resource management tools, such as LVE Manager, PHP X-Ray, and CageFS, which ensure that no single server user can severely harm its performance.
This is the perfect solution for web hosting providers who wish to provide a better, more secure, and high-performing shared hosting environment.
Key Features of CloudLinux OS Shared Pro
CloudLinux OS Shared Pro is a premium solution with additional functionalities for stable, secure, and efficient shared hosting. This release brings a powerful feature set for web hosting providers to improve server performance, block resource abuse, and protect customer data. Here, we discuss in more detail the top 10 features of CloudLinux OS Shared Pro and how each improves the hosting experience for you and your users.
- Lightweight Virtualized Environment (LVE) Manager
LVE Manager is the main technology behind CloudLinux OS Shared Pro. In shared hosting servers, a single website can take up a lot of CPU, memory, or disk I/O, which affects other websites’ performance. This can slow loading times and ruin the user experience for websites sharing the same server.
LVE Manager avoids such problems by:
- Assign per user CPU, memory, and I/O quotas
- Preventing any one website from hogging server resources
- Consistent performance on all hosted websites
It’s an isolation mechanism that allocates resources (memory and CPU time) fairly, so that one application’s heavy use (high CPU use) does not slow down others.
- Get PHP X-Ray – Accelerating Web-Site Performance
However, a slow-loading website hurts user experience and search engine rankings. Memcached Server leverages the benefits of cloud caching technologies to optimize shared hosting service performance. PHP X-Ray is an advanced diagnostic tool in CloudLinux OS Shared Pro that helps identify and resolve performance bottlenecks
PHP X-Ray can:
- Identify slow PHP scripts and bad database queries.
- Find badly optimized plugins, functions, and code.
- Help developers troubleshoot problems more quickly, boosting website performance.
PHP X-Ray delivers detailed performance statistics that help webmasters optimize their PHP applications and ensure visitors the best possible experience.
- Centralized Monitoring Server Insights on the Go
The shared hosting environment can be sophisticated in various aspects when multiple users are entitled to it. With Centralized Monitoring, it becomes easier to administer servers with an overview of their health in real time.
- Advantages of Centralized Monitoring:
Monitors CPU and RAM load, useful for administrators to monitor load on the server
Watches over requests to Apache & MySQL, providing for uninterrupted use of the database
Proactively detects server problems and minimizes downtime
This means hosting providers can benefit from monitoring this information before it negatively impacts users by causing related services or applications to hang, breach thresholds, etc.
- Preventing Excessive File Creation:
This means that there is an inode per file on a Linux server. Over-creating files may slow down your performance and cause the server to be unstable. CloudLinux OS Shared Pro released a new feature called Inode Limits, which limits the number of files a user can create.
Why is this important?
- Prevents any one user from uploading too many files and crippling the server
- Guarantees the spread of storage resources
- Top Server Performance Maintaining
Hosting providers can also apply inode restrictions per user to guarantee a well-balanced shared hosting environment.
- Kernel Hardening with Security Enhancements
Security is a major issue in shared hosting environments. If one website has a vulnerability, then all the websites on that server are at risk. As part of CloudLinux OS Shared Pro, we use a kernel that is hardened with many layers of protection against threats.
Key security enhancements:
- Shields generic vulnerabilities and malware
- Block root-level exploits, so attackers have a harder time taking over
- Better Data Privacy, only authorized users can access the data
Such capability makes CloudLinux OS Shared Pro one of the most secure solutions for shared hosting worldwide.

- CageFS Technology Separate Environment per User
Data exposure is one of the greatest risks in shared hosting. It can be risky if other users can view user files and configurations. In CloudLinux OS Shared Pro, CageFS technology eliminates the problem by providing each user with a virtualized view of the file system.
How does CageFS work?
- Each user is virtualized, sandboxed, separated from the others
- No access to files / sensitive data belonging to others
- Helps prevent hacking and fighting unauthorized access
With CageFS enabled, cloud hosting service providers can ensure a more secure environment by ensuring complete user independence.
- Resource Isolation, Fire And Forget To Avoid Server Slowdown
However, a single user running a resource-eating application in many shared hosting environments can slow the entire server down. CloudLinux OS Shared Pro isolates users, preventing these issues.
Pros of isolating resources:
- Guarantees no activity of one user affects another
- Stops resource abuse from slowing your server down
- Delivers seamless hosting and reliable performance
For hosting providers, this option helps ensure that users fairly consume system resources without impacting others.
- SQUAT Symlink-Based Attack Detection
This is one of the most common attacks on shared hosting, where hackers can access other users’ files on their servers. CloudLinux OS Shared Pro’s Secure Links Protection mitigates this risk with:
- Preventing access to system files without authorization
- Preventing symlink attacks by default
- Improving the security of all servers
This feature allows cloud hosting providers to close off a potential security hole that attackers frequently exploit.

- MySQL Governor Limiting Resource Usage for Databases
MySQL queries can heavily impact a database server, the backbone of many websites. However, heavy usage can lead to a slow database server. MySQL Governor in CloudLinux OS Shared Pro prevents a single user from abusing MySQL resources.
How it works:
- Per user MySQL query monitoring and limiting
- Protects Against One User Overloading the Database
- Professional performance of High Availability MySQL
MySQL Governor allows balancing database usage. This enables all hosted websites to remain operational, without crashing due to exceeding MySQL maximum limits within the database server.
- Mod_Lsapi – Fast & Stable PHP Processing
PHP is the backbone of most WordPress, Joomla, and Drupal websites. Traditional PHP handlers like CGI and FastCGI need many resources, not to mention the definition in configuration. CloudLinux OS Shared Pro Mod_Lsapi is one of the fastest PHP handlers, offering multiple performance improvements.
Why Mod_Lsapi?
- Executes PHP scripts at a high speed to minimize the load time.
- Consume less CPU and memory resources, which helps in efficiency
- Improves the speed of websites, providing a more enjoyable user experience
If you plan to host websites and provide a faster and more stable PHP, Mod_Lsapi is a requirement.
