CloudLinux is a favourite among web hosting providers who focus on providing customers with uninterrupted excellent performance. So…
What is CloudLinux OS?
CloudLinux is a Linux distribution prominent among the hosting providers. As mentioned earlier, it is based on CentOS bt uses a modified kernel which is based on OpenVZ kernel. On top of that, it includes kernel-level technology called LVE (Lightweight Virtual Environment) that allows you to control CPU and memory per-tenant basis.
CloudLinux is a basis for application-level virtualization. It delivers advanced resource management, better security and performance optimizations targeted explicitly for multi-tenant hosting environments.
Since it’s built to handle multitenancy, it improves server stability, density and security by isolating each tenant and giving then the allocated server resources. Instead of having a traditional shared hosting platform, CloudLinux makes it possible to create an environment similar to a virtual server.
This reduces operating costs and churn rates which results in a better service and a more significant profit. With the help of LVE, CloudLinux makes it possible to isolate each tenant by partitioning, allocating and limiting server resources (RAM, CPU, memory) for each tenant.
This ensures that the tenants will not jeopardize the stability of the servers. Another noteworthy mention is that CloudLinux can “cage” each tenant to avoid any malicious breaches. This means that if one tenant is infected with malware, it will be contaminated in his cage and not affecting the others on the server.
Key tools used in CLoudLinux
CloudLinux allows administrators to get the best out of their hosting environments. The following tools are the major players in CloudLinux:
This allows the server admins to limit the server resource usages for each cPanel account. The LVE manager prevents one cPanel account (or one tenant) from using up all the available resources, which is a common occurrence on servers with multiple tenants.
CageFS creates a virtualized user environment that prevents users from seeing other users on the same server. This keeps each user in their respective cages where the user will have full functionality to the system files, tools etc. The key benefits of CageFS are:
- Only safe binaries are available for the user
- The user will not see any other users on the server
- The server configuration files are hidden from the user
- The user will have a limited view of the /proc file system and will not see other user’s processes
- Any executable malware opened by one user will not reach other cages and will be contained
PHP Selector is a tool that can change the PHP settings and set limitations within a user account. This is very beneficial if you run numerous CMS style websites on the same server where each requires different PHP modules. This allows the users to select the PHP versions that they prefer from PHP 5.2 -7.4
Difference between CloudLinux and CentOS
Both CentOS and CloudLinux are Linux distributions, but CloudLinux is often used as a replacement for CentOS operating system. CentOS is still an extremely reliable choice for web hosting solutions, but CloudLinux’s specific features make the administration part smoother.
As mentioned earlier, it separates customers into tenants on a shared server. This secures the server from experiencing slower speeds due to the activities of other customers.
Both systems share many key features, but CloudLinux stands out from the other due to the:
- Greater stability
- Increased efficiency
- Advanced security
- Greater compatibility
- Lower operating costs
This is a list of all the major CloudLinux features:
1. A VPS like environment for your clients
With the use of LVE, CloudLinux can deliver a unique set of server resources to each tenant on the server. This means that each website on the server has its dedicated resources that are not shared among other accounts.
CloudLinux allows monitoring and controlling limits such as CPU, RAM and I/O usages. It isolates the users from each other to avoid neighbour effects and prevents users from seeing configuration files or any additional private information.
2. Greater stability
Due to its lightweight structure, CloudLinux is able to deliver greater stability to the users. Due to the structure, it ensures the users from overloading the server. The combination of stability and separate virtual environments results in a decreased risk of server downtime and keeping the site up and running 24/7.
3. Secured and hardened Kernel
CloudLinux’s increased security measures prevent malicious users from attacking other website accounts hosted on the same server. This is due to the isolated environments given to each user by LVE. CloudLinux also uses HardenedPHP, which address the security vulnerabilities of old and outdated versions of the programming language.
The hardened Kernel also protects against trace exploits and symlink attacks while limiting the filesystem’s visibility to only the files that the users need to access.
4. Compatible with all major control panels
CloudLinux is compatible with almost all the control panels, including cPanel. Depending on the hosting plan that you will get, you can have the option to control your website resources directly from cPanel, which is not always available with other operating systems.
Due to its higher level of compatibility between interfaces, it gives users the option to choose their favourite control panel.
5. Monitors and operates MySQL usage
In a shared hosting environment, keeping MySQL stable can be quite tricky, and customer queries can easily slow down your site. CloudLinux’s MySQL Governor Tool helps system administrators to pinpoint abusers and throttle them in real-time.
It tracks CPU and disk IP usage for every website account in real-time and reduces MySQL queries. With the support of MySQL and MariaDB, it is a must-have for any shared hosting provider.
6. Lower operating costs
The operating system makes it easier for hosting providers to allocate resources, leaving room to add more tenants to the server. The simplicity of the administrator interface also gives hosting providers a more comfortable platform to manage. This results in fewer hours spent configuring and monitoring the servers, helping to decrease the overall costs of the hosting plans.
The final verdict is that there are a lot of advantages and benefits of using CloudLinux for your hosting needs. It caters specifically to hosting administrators to have a smoother experience when carrying out their service.
If you are a hosting provider looking to invest in a dedicated server, we provide the best in the market. You can get your dedicated server powered by CloudLinux and make the necessary configurations to start your very own shared hosting platform with ease.
