About CloudLinux

What is a CloudLinux license?

CloudLinux is a CentOS / AlmaLinux derivative built specifically for shared hosting. It adds Lightweight Virtual Environments (LVE) for per-account CPU/RAM/I/O caps, CageFS for filesystem isolation, PHP Selector for per-account PHP versions, and MySQL Governor for query isolation. KernelCare adds rebootless kernel patching. Licenses are server-count tiered.

Who it's for

Who buys a CloudLinux license from us

Shared and reseller hosts who need per-account isolation, hosts moving off CentOS who want a long-term LTS replacement, and datacenter operators looking for KernelCare live patching across large fleets.

FAQ

CloudLinux license questions

Is CloudLinux a replacement for CentOS?
Yes — CloudLinux is binary-compatible with RHEL/CentOS/AlmaLinux and adds the hosting-specific features (LVE, CageFS, PHP Selector). Migration from CentOS is in-place.
Do I need KernelCare?
If you can't afford to reboot for kernel CVEs — yes. It's included on Pro and Enterprise. Solo and Standard ship without it; you can add it as an upgrade at any time.
Is Imunify360 included?
On the Enterprise tier, yes. On other tiers it's available as a separate license — talk to sales for bundle pricing.
How does CloudLinux license server-count work?
Each tier caps the number of physical or virtual servers you can install on. Solo is 1, Standard is 5, Pro is 20, Enterprise is unlimited. You can move a license between servers from the dashboard.
