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.
How it works-
CloudLinux in a cPanel web hosting environment creates an individual virtual container for each website. System administrators can then set hard limits for individual websites so that the performance and security of one website can’t impact on the performance of its neighbors. Parameters that can be set include the amount of CPU power that a single website can use and disk IOPS; these are beyond what a regular cPanel installation can facilitate, which is often limited to specific account features like MySQL databases and FTP accounts. With each virtual container having a pre-determined hard limit, you can make much more accurate predictions about potential server load, enabling you to retain adequate spare capacity.
The virtual container can act as a buffer against any websites that are targeted. So if a website using a cPanel hosting package is compromised, only that particular website and environment is affected hackers will have no way of breaking out of that environment to attack other websites and data.
Users will now know when it’s time to upgrade to a new type of hosting. CloudLinux helps to keep shared hosting a fair business with which all clients get access to their full entitlement of resources. When a user hits their limits, then they know it’s time to start optimizing their website to make better use of their available resources, or alternatively to upgrade to a more powerful form of web hosting, i.e. a VPS or dedicated server.
Its Importance in cPanel Web Hosting–
As a summary, CloudLinux enhances cPanel hosting by isolating each website in a secure container, preventing threats from spreading. It limits resources per site, ensuring fair usage and reducing server strain. Gotmyhost utilizes CloudLinux for optimized security and performance in shared hosting.
