Found this but need to know what it means in English : LVE ... the CloudLinux team. The technology has common roots with container based virtualization. Yet, it is lightweight, and transparent. Today, a single site can consume all CPU resources, IO resources or apache processes -- and bring the server to a halt. LVE prevents that. It is done via collaboration of apache modules and kernel. mod_hostinglimits is apache module that: 1. Detects VirtualHost from which the request came. 2. Detects if it was meant for cgi or PHP script. 3. Switches apache process used to serve that request into LVE for the user determined via UserGroup for that virtual host. 4. Lets apache to serve the request. 5. Removes apache process from user's LVE. The kernel makes sure that all LVEs get fair share of the server's resources. This means, for example, that 20 apache processes serving a heavy site will use the same amount of CPU as one apache process serving a smaller site. Each LVE limits amount of entry processes (Apache processes entering into LVE) to prevent single site exhausting all apache processes. If the limit is reached -- mod_hostinglimits will not be able to place apache process into LVE, and will return error code 503 (server busy). This way a very heavy site would slow down and start returning 503 errors, without affecting other users. Sounds good, it's installed on a badass server, but it's still shared hosting. Priced between shared and a vps. Discuss please.
