Imagine a shared server with hundreds of accounts. One site starts a runaway PHP process or fills disk I/O — and every neighbor slows to a crawl. CloudLinux exists to stop that story. It adds tenant isolation and per-account resource limits on top of a normal AlmaLinux/RHEL-style base so shared hosting stays predictable.
CageFS and LVE in plain language
- CageFS isolates each user so they cannot casually read other users’ files
- LVE caps CPU, I/O, memory, and entry processes per account so noisy neighbors are throttled instead of melting the node
Who should run CloudLinux
If you sell shared hosting on cPanel-style stacks, CloudLinux is close to mandatory ops hygiene. Even reseller nodes benefit: fewer “the whole server is down” tickets, clearer per-user limits, and safer multi-tenant defaults.
Licensing without the retail shock
Retail CloudLinux adds another line item per server. A shared CloudLinux license keeps the same isolation features while lowering monthly cost — the same activation flow as other LicenseBoy products.
