Over the last few months, DigitalFlare has rolled out CloudLinux on most of our cPanel web servers.
CloudLinux is a Linux-based operating system designed to give shared hosting providers a more stable and secure OS. Essentially a set of kernel modifications to the Linux distribution, CloudLinux implements features to enable system administrators to take fine-grained control of their server’s resource usage. By isolating users, CloudLinux helps ensure that problems with one account don’t degrade the service for others.
CloudLinux virtualises user accounts using a feature called LVE (Lightweight Virtual Environment). Each LVE is allotted a certain amount of resources (memory, CPU, etc.) separated from the server’s total resources.
In addition to CloudLinux OS, we also run Imunify360 for hardened security.
CloudLinux, and Imunify360 (as well as a customised version of CFS), help us reduce the risk associated with vulnerabilities and collaborate with cPanel security settings.
