CloudLinux is a specialised operating system designed for shared web hosting servers. It helps improve the stability, security, and performance of shared hosting environments by isolating individual hosting accounts and controlling the resources available to each account.
At SIRSTEVEHQ, CloudLinux powers our Shared Hosting services, including:
- cPanel Hosting.
- DirectAdmin Hosting.
- Plesk Hosting.
By isolating hosting accounts and managing resource usage, CloudLinux helps provide a more stable and reliable hosting environment for customers sharing the same server.
How Does CloudLinux Work?
CloudLinux isolates individual hosting accounts using Lightweight Virtual Environment (LVE) technology.
Each hosting account operates within its own resource limits, which can include:
- CPU.
- Memory (RAM).
- Entry Processes.
- I/O (Disk Input/Output).
- Number of Processes.
This resource isolation helps prevent a single website from consuming excessive server resources and negatively affecting other websites hosted on the same server.
What Are the Benefits of CloudLinux?
CloudLinux provides several benefits for shared hosting environments, including:
- Improved server stability.
- Better account isolation.
- More consistent resource allocation.
- Reduced impact from resource-intensive websites.
- Improved hosting reliability.
- Greater control over resource usage.
- Enhanced security between hosting accounts.
These features make CloudLinux a popular choice for managing shared hosting environments where multiple customers and websites operate on the same server.
PHP Selector
One of CloudLinux's useful features is the PHP Selector.
It allows customers to manage supported PHP versions and settings directly from their hosting control panel.
Depending on the hosting environment, customers can:
- Select from available PHP versions.
- Change their PHP version without contacting support.
- Enable or disable supported PHP extensions.
- Adjust available PHP settings for their hosting account.
This provides greater flexibility while maintaining appropriate controls over the shared server environment.
Does CloudLinux Improve Security?
CloudLinux provides account isolation and security features that help separate hosting accounts from one another.
If one website experiences a security issue or is compromised, account isolation can help reduce the potential impact on other websites hosted on the same server.
CloudLinux can also operate alongside additional security technologies, such as Imunify360, to provide additional protection for the hosting environment.
However, CloudLinux is not a replacement for website security practices. Keeping your CMS, plugins, themes, applications, and passwords up to date remains important.
Can I Install Custom PHP Extensions?
No.
The PHP Selector allows you to enable or disable supported PHP extensions that are already available on the server. It does not allow customers to install custom server-level PHP extensions.
If your application requires custom PHP extensions, server-level software, or greater control over the server environment, you may need a Cloud Server solution such as:
- Unmanaged VPS.
- SIRSTEVEHQ Cloud.
- AWS Hosting.
- Google Cloud Hosting.
These solutions provide greater control over the server environment compared with shared hosting.
Does CloudLinux Make My Website Faster?
CloudLinux can contribute to a more stable and consistent hosting environment by controlling how server resources are distributed between hosting accounts.
However, CloudLinux does not automatically make every website faster. Website performance also depends on factors such as:
- Website optimisation.
- PHP version.
- Image and media sizes.
- Themes and plugins.
- Database performance.
- Caching.
- Website code.
- Available hosting resources.
A well-optimised website combined with an appropriate hosting environment can provide better overall performance.
Who Should Choose CloudLinux Hosting?
CloudLinux-based shared hosting can be suitable for:
- Business websites.
- WordPress websites.
- Blogs.
- Company websites.
- Portfolio websites.
- Small and medium-sized businesses.
- Developers hosting multiple websites.
It is particularly useful for customers who want the convenience of shared hosting while benefiting from resource isolation and improved server stability.
