Method and apparatus for calculating importance degrees for resources

摘要

A method for calculating an importance degree for a resource according to this invention includes: receiving a first importance degree assigned to a resource node to be allocated or having been allocated to a specific business service based on an original policy in the specific business service; and converting the received first importance degree to a second importance degree in an entire system according to data concerning an importance degree re-calculation policy, which is set for the specific business service independently of the original policy. Because the second importance degree in the entire system is re-calculated according to the importance degree re-calculation policy, it is possible for an operation administrator of the entire system to flexibly and appropriately set the importance degree re-calculation policy so as to optimize the resource allocation of the entire system.
