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.
