OpenVZ Philosophy 14

Resource Management

OpenVZ Resource Management controls the amount of resources available to Virtual Private

Servers. The controlled resources include such parameters as CPU power, disk space, a set of

memory-related parameters. Resource management allows OpenVZ to:

 Effectively share available Hardware Node resources among VPSs;

 Guarantee Quality-of-Service (QoS) in accordance with a service level agreement (SLA);

 Provide performance and resource isolation and protect from denial-of-service attacks;

 Simultaneously assign and control resources for a number of Virtual Private Servers, etc.

Resource Management is much more important for OpenVZ than for a standalone computer

since computer resource utilization in an OpenVZ-based system is considerably higher than that

in a typical system.
