CloudLinux – is the OS optimized for shared hosting or server providers which helps to provide stability, security and performance of customer web hosting environment. It is based on the CentOS (and now AlmaLinux) distro and unites many technologies and features to enhance the hosting process for providers and end clients. 

 The following are fundamental features of CloudLinux along with its benefits; 

 LVE (Lightweight Virtual Environment) 

 Resource Allocation: LVE enables the administrators to distribute a particular resource, say CPU, RAM, or I/O, to clients, or a user, or a website if they are acting as a tenant on a shared server. 

 Stability: Ensures that one tenant does not take up a lot of facility and end up compromising on other tenants’ business. 

 CageFS 

 Isolation: Having a user space virtualized file system also each tenant has complete isolation. 

 Security: Restricts each user to his or her own files and does not display other users on the server, which increases security. 

 MySQL Governor 

 Database Management: Detect and manages MySQL usage on a per-tenancy basis. 

 Performance: Aids in controlling woes that may plague databases by not permitting one user to inundate the database server. 

 PHP Selector 

 Multiple PHP Versions: This permits the selection of the required PHP version, may it be the current versions or the past ones. 

 Customizable: Another importance of PHP is that users can make settings on PHP to be as per their application needs. 

 Node. A list of selectors which includes Js, Python, and Ruby. 

 Versatility: This way, the possibility of further support for various application scenarios can be provided, which would allow to run Node. JS, Python, and Ruby applications, will be able to perform distributed computing in formation of clusters and conduct P2P exchanges in complex networks based on a working decentralised P2P application layer. 

 Hardened Kernel

 Security: Strengthen security of the server as well as prevent different types of attacks as well as various other threats. 

 Stability: Which in turn helps avoid the chances of kernel panic or even a crash. 

 Imunify360 

 Security Suite: Over is a good package of protection that includes Malware scan, Firewall, Intrusion detection/Prevention and Active protection. 

 Web Application Firewall (WAF): Safeguards the website against already identified risks and threats. 

 Automated Updates and Patching 

 Maintenance: This allows all the package and also the kernel to receive update security patches without having to reboot the network. 

 Resource Usage Statistics 

 Monitoring: The detailed statistics and the graphs as the indication of the resource usage per tenant. 

 Optimization: Assists in detection of programs that consume a lot of resources and general enhancement of the servers. 

 Benefits for Hosting Providers 

 Improved Stability: It is designed in a manner that will control tendencies that see tenants isolated from other users or limit resources to the extent that a particular user will not affect the entire shelf, hence offering an environment that is relatively stable. 

 Enhanced Security: There is anti-virus software called CageFS and Imunify360 that ensures server and its users safety from potential dangers. 

 Better Resource Management: Based on the examples of LVE and MySQL Governor, it is now possible to adjust the resources in a proper way. 

 Flexibility for Users: Some of these are PHP Selector and Multiple Language Support that enable users to host different types and varieties of applications. 

 Reduced Support Costs: CloudLinux, as a result, creates a more stable and secure platform on which the preverbal administration occurs, thus fewer support tickets are being opened and much less administrative work is being done. 

 Use Cases 

 Shared Hosting: CloudLinux is suitable especially with the shared hosting geo where a lot of customers are hosted within the same server. 

 Reseller Hosting: Currently, CloudLinux is beneficial for hosting providers that offer reseller hosting, because of the resource management and isolation options. 

 Web Hosting Companies: Any web hosting company wishing to take its server stability, security, and performance to another level can benefit from CloudLinux.
