Shield your servers from performance spikes and prevent slowdowns and downtimes by limiting and partitioning resources per user, thus reducing resource spikes and support costs.
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.
CageFS uniquely encapsulates each customer, preventing users from seeing each other and viewing sensitive information. It prevents a large number of attacks, including most of the privilege escalation and information disclosure attacks.
In old PHP versions, including widely used 5.2, 5.3, and 5.4, vulnerabilities, even if discovered, are not patched by the PHP.net community. HardenedPHP fixes those vulnerabilities and secures old and unsupported versions.
SecureLinks is a kernel-level technology that prevents all known symbolic link attacks, which further enhances the security level of the servers.
Host more customers on one server by allocating server resources to allow for the highest density of tenants, with up to 80% of server utilization.
With PHP Selector your customers will have the flexibility to choose any PHP version they need, including 4.4, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, and 7.0. CloudLinux OS also ensures that PHP is updated fast, making sites more secure and customers happy.
The Ruby Selector allows your customers to choose a Ruby version for applications and install additional modules (gems) to the application environment.
