CloudLinux OS — Complete Isolation
The operating system that turns shared hosting into a safe, stable environment. Every account is fully isolated — your resources, files and processes are invisible to other users.
What is CloudLinux OS?
CloudLinux is a Linux operating system built specifically for shared hosting. Unlike a standard Linux server, CloudLinux adds a lightweight virtualization layer that fully isolates each account.
CageFS — Private file system
Every user operates within their own virtualized file system. Even if you share a server with other clients, they cannot see your files, processes or configurations.
LVE — Guaranteed resource limits
CPU, RAM, I/O and the number of processes are limited per account through LVE (Lightweight Virtual Environment). A neighbor consuming resources heavily cannot affect your performance.
MySQL Governor — Database control
Monitors and limits SQL queries that consume excessive CPU. Your site will not be affected by heavy queries from other users.
PHP Selector — PHP version per domain
Change the PHP version (5.6–8.5) independently per domain, directly from cPanel, without affecting other accounts on the server.
Everything that makes CloudLinux remarkable
Six integrated technologies working together to guarantee stability, security and performance on shared servers.
CageFS — Complete Isolation
Every account has its own virtualized file system. Your files, processes and configurations are invisible to any other user on the same server.
LVE — Guaranteed Resources
CPU, RAM, disk I/O and concurrent processes are guaranteed and allocated per account. No neighbor can consume your resources, regardless of their traffic or scripts.
PHP Selector (5.6–8.5)
Choose the PHP version per domain without affecting the server or other users. Upgrade instantly to PHP 8.5 or keep compatibility with an older version.
MySQL Governor
Monitors MySQL queries in real time. If a query consumes excessive CPU, it is limited automatically — without affecting the performance of your database.
Kernel Hardening
The Linux kernel modified by CloudLinux adds extra protections against security exploits and privilege escalation — an essential defense layer at the OS level.
Zero Noisy Neighbor
The classic shared-hosting problem — one site consuming all of the server's resources — is eliminated entirely through the LVE limits applied to each individual account.
How CageFS works
On every HTTP request, CloudLinux activates isolation within a few milliseconds — transparent to the user, essential for security.
Request received
The web server (Apache/Nginx) receives the HTTP request for your site and routes it to your PHP/Python process.
CageFS activated
CloudLinux places the process in an isolated CageFS environment — it sees only its own file system, not the server's real one.
LVE checks resources
The kernel verifies in real time that the process does not exceed the CPU, RAM and I/O limit allocated to your account through LVE.
Guaranteed response
The request is processed and the response returned to the user — with no interference from other accounts on the server.
LVE limits per hosting plan
Every Trustnet Solutions plan includes guaranteed CloudLinux resources. These are hard limits — unaffected by the activity of other accounts.
| LVE resource | Starter | Classic ★ | Advanced | Professional |
|---|---|---|---|---|
| CPU (virtual cores) | 1 vCPU | 1.5 vCPU | 2.5 vCPU | 3 vCPU |
| Guaranteed RAM (DDR5) | 1 GB | 1 GB | 2 GB | 3 GB |
| Disk I/O speed | 10 MB/s | 10 MB/s | 15 MB/s | 20 MB/s |
| Concurrent processes | 30 | 40 | 50 | 60 |
| Input/Output (IOPS) | 200 | 200 | 500 | 1.024 |
| CageFS isolation | Included | Included | Included | Included |
| MySQL Governor | Active | Active | Active | Active |
LVE limits are applied at the kernel level — they cannot be exceeded by any process, regardless of the volume of requests.
