CloudLinux is a Linux-based operating system, essentially a set of Linux kernel deployment modifications that perform functions to allow system administrators to control the use of their server resources in detail, isolating users from account problems that do not result in service degradation For others. CloudLinux virtualizes user accounts such as LVEs (LightWeight Virtual Environment). Each LVE is assigned a certain amount of resources (memory, CPU, etc.).
If a specific site account receives a large amount of traffic or starts using a large amount of CPU or memory due to a malicious attack, weak attack, or denial of service, it will slow the speed of the LVE (Site Account). Therefore, you still have the entire server with other accounts for websites that work without any potential problems, such as slow sites, inactivity problems, and so on.
