CloudLinux OS is a Linux distribution primarily aimed at Shared Hosting providers developed by CloudLinux, Inc. CloudLinux is developed based on CentOS using the OpenVZ kernel and RPM Package Manager. CloudLinux is found. It was first released in 2009 by Igor Seletskiy and the first initial release was made in January 2010.

Since CloudLinux was launched in 2010, more than 2,000 security-conscious shared hosting companies, representing more than 20,000 servers, have chosen CloudLinux because it is optimized. Optimized for shared hosting by separating each customer with a technology called “Lightweight Virtualized Environment” (LVE), where each LVE is allocated a certain amount of resources.​

We can summarize the main points as follows.

1. Make Your Server Stable​ Stability Is the key to success in shared hosting because stable servers make both you and your customers happy. There are no unusual usability issues and it will also help you increase your number of customers and expand your profits. CloudLinux Stability protects servers from performance spikes and prevents slowdowns to the point of halt by limiting and allocating resources per user, which helps reduce abnormal server resource usage and control costs. value service
A Lightweight Virtualized Environment is a kernel-level technology that isolates each tenant into its own environment and provides a number of resources (CPU, IO, Memory,Number of Process, etc.) that can be used – unique to each client. If the tenant reaches the limit Other users won’t notice anything as the culprit is immediately throttled. This reduces the use of server resources beyond Resource.

2. Make Your Server Secure​ Because of the Shared Hosting service that has a Linux Based server system, when there are many users on the system, if any of the service users has a vulnerability in their own coding, resulting in being Hack into the system, this would have the opportunity to create problems for Shared Hosting service providers because the original system still has a channel for these ill-wishers to spread the problem to other users on the machine. ​CloudLinux can handle this problem. With CageFS and SecureLinks technology, users are virtualized in their own file system, preventing each user from seeing another user on the server.

3. Make Your Server Profitable​ The high level of stability provided by CloudLinux makes every server more efficient and allows the number of clients on each server to be cost effective. This will allow you to greatly improve the utilization of your server. In addition, a highly secure server system will help your customers to have confidence and want to use a secure service.​
This can be done by setting resource limits for each customer. This makes it possible when the user reaches the limit, you can increase your sales even higher or plan better without moving to another server. Additionally, by creating hosting packages based on resource usage and flexibility features such as support for different PHP versions, you can change your pricing policy completely.

4. Make Your Server High-Performing​ The CloudLinux system offers a powerful set of features that dramatically increase the performance of your server. For example: mod_lsapi Much faster than other methods of serving PHP to Apache.

5. Highly Compatible CloudLinux System Compatible with all major Control Panels. Currently, those Panels are based on CentOS and RHEL.
