摘要：A method, in a virtualised system, for balancing a load across multiple virtual

machines instantiated over physical hardware of the system, comprising vertically scalingthe capacity of respective ones of the VMs up to a physical capacity limit, L, from aninitially allocated physical capacity, L, by providing access to additional resources of thephysical hardware in response to an increased load causing the or each VM to reach orexceed a threshold capacity L, and horizontally scaling the capacity of the system bysupplementing the multiple VMs with an additional VM instantiated using a hypervisor ofthe system when a predefined proportion, U, of the VMs have a capacity L.
