Are you considering switching to a hosting provider that offers cloudlinux? I've heard that such hosting boasts fast performance, immunity to the effects of other servers, and exceptional stability. Is my understanding accurate?
Do you think it's a worthwhile move, and if so, which provider do you recommend?


CloudLinux and Cloud hosting are not the same thing.

CloudLinux is an operating system that is based on CentOS but has a different kernel and utilities. Although the name may suggest otherwise, it is not related to cloud infrastructure. It was designed specifically for shared hosting and allows the resources of a physical machine to be thinly divided between multiple server users. Large projects that require virtualization or hypervisors are not supported.

On the other hand, Cloud hosting offers a range of features including hypervisors, containers, guest OS, and more. Hosting providers typically offer a variety of plans and options to choose from.

It's important to note that heavy scripts on CloudLinux can consume significant resources which will impact website performance. In this case, migrating to a VPS may be a better solution. Popular control panels often have graphical interfaces that display resource consumption such as CPU usage, allocated bandwidth, memory usage, process count, and more.


When hosting multiple websites on a single server, it's common to encounter situations where an increase in load on one site drastically slows down or even blocks the performance of others. CloudLinux addresses this challenge by isolating each user from one another and limiting consumption of system resources. This results in increased stability and security, higher density of user placement on servers, and lower maintenance costs.

CloudLinux relies on LVE (Lightweight Virtual Environment) technology to differentiate resource allocation between users. It provides complete separation of each user from others, and allows for setting limits on CPU power consumption, number of processor cores used, physical and virtual memory usage, disk I/O speed, number of simultaneous processes, and ability to create new processes. Additionally, CloudLinux features MySQL Governor tool that restricts use of a database server by all MySQL users, and CageFS tool that creates a virtual file system for each user, isolating them from other users and the root FS.

To check whether your hosting provider uses CloudLinux, run the command "uname -a". If the kernel name and version contain "LVE", it's likely that CloudLinux is in use. CloudLinux can be managed using command line interface, or integrated with hosting control panels like cPanel, Parallels Plesk, DirectAdmin, ISPmanager, Webmin, and Interworx without any additional configuration.
