VIRTUAL COMPUTING INFRASTRUCTURE

摘要

A system has a virtual overlay infrastructure mapped onto physical resources for processing, storage and network communications, the virtual infrastructure having virtual entities for processing, storage and network communications. The system has a mapping manager to dynamically alter the mapping for balancing, performance, and redundancy. There can be more independence from the underlying physical configuration, compared to known methods of virtualising only some of the entities. The mapping manager can be distributed across a number of entities on different physical servers arranged to cooperate with each other.
