SYSTEM AND METHOD FOR DYNAMICALLY ALLOCATING RESOURCES OF VIRTUAL MACHINES BASED ON SERVICE-LEVEL AGREEMENTS (SLA) AND PRIVILEGE LEVELS OF USERS

摘要

Systems and methods for dynamically allocating resources of virtual machines (VMs) using service level agreements (SLAs) and privilege levels of users. The system includes VM servers for executing the VMs. When a software application is to be executed on one executed VM on a VM server, a management device determines, from a first table, the privilege level of each executed VM based on the SLA, and then retrieves, from a second table, the resource allocation information for the software application to be executed using the privilege level of the executed VM. If, based on the resource allocation information, the resource of the VM server is determined to be unavailable for execution of the software application, one or more executed VMs having a lower privilege level on the VM server may be migrated to other VM servers to free up the resources.
