CloudLinux OS is the leading platform for multitenancy. 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.
The CloudLinux OS stability features prevent resource spikes and make your servers rock-solid stable, even in the most stressful situations.
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 utilization of your servers. Before CloudLinux OS, you couldn't utilize 20–30 % of your server without affecting stability, but now you can have up to 80 % of your server utilized at any given time. Profitability is also increased by the high level of security CloudLinux OS provides. Highly secure servers allow your customers to enjoy safe shared hosting, which decreases support inquires.
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.
