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
- Dedicated resources per customer: each account gets its own guaranteed CPU and memory.
- Stable hosting: traffic spikes on other sites don't take yours down.
- Hardened kernel: helps stop malicious users from attacking other accounts on the server.
- Multiple PHP versions: the PHP Selector lets each customer choose their PHP version and extensions and adjust PHP settings.
- 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.
