Security
CloudLinux OS improves server stability, density, and security by isolating each tenant and giving them allocated server resources.
CloudLinux keeps your servers up and your server administrator happy even under extreme stress. That’s because each tenant is isolated in their own lightweight virtualised environments (LVE) and given a predetermined amount of resources. If one customer suddenly gets a huge amount of traffic any ill effects will be contained to only that customer. CloudLinux is a fantastic inclusion for all cPanel-enabled servers, both Virtual and Dedicated. With ClouxLinux, per-tenant resource allocation and limits for CPU, IO, and memory reduce server loads and when paired with our performance-enhancing features, this guarantees you the fastest servers.
Traditional shared hosting environments have no control over individual tenants in the event of a resource spike. If one tenant suddenly experiences a big resource spike from a large amount of traffic, poorly written script, or a Denial of Service attack, all the other tenants on the server are slowed or brought down. CloudLinux isolates each tenant so that no matter what, the tenant can never exceed the resources allocated to them. During a sudden resource spike all other tenants are left unaffected.
All of our shared web hosting plans come with cloud linux enabled on them. CloudLinux is capable of isolating each website on a server and create resource limits at the OS level. It works by inserting a custom kernel into the server. By doing this it is able to limit the amount of resources any one site can use, so no single account can slow down the server or take it offline completely.
MySQL Governors monitor MySQL users restricting their connectivity if they start using more than their allocated resources, significantly diminishing the number of server issues caused by MySQL abuse. This translates to greater efficiency, security, stability, and density. Digital Pacific are one of very few companies that currently run Cloud Linux and this is another reason why we do it better. We are also a partner of CloudLinux which means we have access to their developers and support.

CloudLinux OS is the leading platform for multi-tenancy. It improves server stability, density, and security by isolating each tenant and giving them allocated server resources. This creates an environment that feels more like a virtual server than a shared hosting account. All of our cPanel Managed servers include CloudLinux for improved reliability.
Stability is the key to success in shared hosting – stable servers make both you and your customers happy. Stable servers reduce churn and allow you to increase density, and therefore magnify your profit. The CloudLinux OS stability features prevent resource spikes and make your servers rock-solid stable, even in the most stressful situations.
The CloudLinux OS Lightweight Virtualized Environment is a kernel-level technology that isolates each tenant into their own environment and provides them with the amount of resources (CPU, IO, memory, processes, etc.) that can be used – specific to each individual customer. If the tenant hits the limit, other users will not notice anything, because the offender is immediately throttled. This eliminates resource spikes, server overloads, and angry phone calls from customers.
The high level of stability, which CloudLinux OS provides, makes every server more efficient, and that allows you to multiply the number of customers on each server without any stress. By preventing resource spikes, you can drastically improve the utilisation of your servers.
Before CloudLinux OS, you couldn’t utilise 20–30% of your server without affecting stability, but now you can have up to 80% of your server utilised at any given time. Profitability is also increased by the high level of security CloudLinux OS provides.
CloudLinux OS offers a set of powerful features that greatly optimize performance of your servers. For example, mod_lsapi is faster than any other way to serve PHP with Apache.
