Over the last few months, DigitalFlare has rolled out the use of 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 virtualizes user accounts using a feature called LVE (Lightweight Virtual Environment). Each LVE is allotted a certain amount of resources (memory, CPU, etc.) which are separated from the server’s total resources.
In addition to CloudLinux OS we are also running Imunify360 for hardened security.
CloudLinux along with Imunify360 (as well as a customised version of CFS) helps us to reduces much of the risk associated with vulnerabilities and works in collaboration with cPanel security settings.
