CloudLinux is a proven solution for web hosting servers that drastically improves server stability and security, increases density, decreases support costs, and prevents churn. CloudLinux delivers these benefits by introducing the latest technologies specifically crafted for web hosting into its kernel.

What is CloudLinux?
CloudLinux is a linux based operating system designed to give shared hosting providers a more stable and secure OS. Essentially a set of kernel modifications to the Linux distribution, CloudLinux implements features to enable system administrators to take fine-grained control of their server’s resource usage. By isolating users, CloudLinux helps ensure that problems with one account don’t degrade the service for others.
CloudLinux virtualizes user accounts using a feature called LVE (LightWeight Virtual Environment). Each LVE is allotted a certain amount of resources (memory, CPU, etc.) which are separated from the server’s total resources.
If a particular account receives a sudden increase in traffic or begins to use a lot of CPU or memory, rather than slowing the entire server and possibly causing a failure, only that particular LVE will slow down.
CloudLinux Features
-
A Personal Set of Server Resources for Each Customer –With the LVE technology in CloudLinux, each customer’s website account has a separate set of allocated resources. LVE ensures that these resources are not shared with any other website accounts.
-
Stable Hosting Environments – Sudden traffic spikes from one website account will never mean downtime for any other website account or the server as a whole. Since every website account has its own allocated resources they remain protected. This keeps websites running even if a sudden spike in resource usage comes from other websites hosted on the server.
-
Secured & Hardened Kernel –CloudLinux’s hardened kernel helps prevent malicious users from attacking other website accounts hosted on the same server.
-
Multiple Versions of PHP –CloudLinux has a built-in feature called PHP selector. It allows end-users to select the specific version of PHP they need. This allows ultimate flexibility by offering all popular versions of PHP, including more than 120 PHP extensions to choose from.CloudLinux packages PHP versions 4.4, 5.1, 5.2, 5.3, 5.4, 5.5, and 5.6. The convenient UI lets customers switch between versions, select extensions, and adjust PHP settings as needed.
