# What Is CloudLinux?

**In short:** **CloudLinux** is an operating system for shared hosting servers that puts every account in its own lightweight virtual environment (**LVE**) with fixed limits on CPU, RAM, disk I/O, processes and files. If one site overloads, only that site slows down; the others keep running. All Hyyat Host hosting servers run CloudLinux.

## What is CloudLinux?

CloudLinux is a Linux-based operating system with kernel changes that give server administrators precise control over resource usage and isolate users, so problems in one account don't degrade service for others.

## The problem in traditional shared hosting

On a shared server, hundreds of websites share the same resources. Without limits, one site using an unfair share (because of a DDoS attack, a badly written script or a traffic spike) can slow down or crash the whole server and every site on it. Finding the culprit takes time and often means suspending accounts.

## How CloudLinux solves it

CloudLinux places each account in its own LVE (LightWeight Virtual Environment) with a set amount of resources. If a site reaches its limits, only that site is affected, and the other sites on the same server keep working normally.

## What CloudLinux limits

- **CPU** usage
- **RAM** (physical memory)
- **I/O**: disk read and write speed
- **Entry processes**: simultaneous connections to PHP
- **Inodes**: the number of files

## Security with CageFS

CageFS isolates each user so they can't see or access other users' files, and system files are read-only, which makes shared hosting much safer.

## CloudLinux features

1. **Dedicated resources per customer:** each account gets its own guaranteed CPU and memory.

2. **Stable hosting:** traffic spikes on other sites don't take yours down.
3. **Hardened kernel:** helps stop malicious users from attacking other accounts on the server.
4. **Multiple PHP versions:** the PHP Selector lets each customer choose their PHP version and extensions and adjust PHP settings.

5. **Stable MySQL:** MySQL Governor tracks each account's database usage in real time and throttles heavy queries within its limits.

**Note:** CloudLinux is a paid system, and all Hyyat Host hosting servers run it.
