Physical resource allocation method, device and system

Abstract

The embodiments of the invention provide a physical resource allocation method, a physical resource allocation device and a physical resource allocation system. The method comprises the following steps: receiving a virtual machine request sent by a user through a terminal, and judging whether the target ratio of hard disk capacity to memory capacity carried by the virtual machine request is higher than a predetermined ratio; if the target ratio is higher than the predetermined ratio, allocating a cloud virtual machine to the user according to the hard disk capacity and the memory capacity carried by the virtual machine request and based on a physical machine associated; if target ratio is not higher than the predetermined ratio, feeding notification information about changing the hard disk capacity and the memory capacity according to the predetermined ratio back to the terminal; when a change request is received, judging whether the ratio of the hard disk capacity after change to the memory capacity after change is higher than the predetermined ratio; and if the ratio of the hard disk capacity after change to the memory capacity after change is higher than the predetermined ratio, allocating a cloud virtual machine to the user according to the hard disk capacity after change and the memory capacity after change and based on a physical machine associated. The scheme provides a more optimized configuration of physical resources, and can improve the utilization rate of hard disk resources and memory resources of a physical machine associated with a cloud server.

Description

technical field [0001] The invention relates to the technical field of resource allocation, in particular to a computer hardware physical resource allocation method, device and system. Background technique [0002] Nowadays, instead of purchasing a physical machine, a user can obtain computer resources by requesting a cloud server to purchase a cloud virtual machine. Physical resources, namely: the physical machine in the cloud is the physical resource provider of the cloud virtual machine requested by the user. [0003] In the prior art, after receiving the virtual machine request sent by the user through the terminal, the cloud server allocates a virtual machine to the user according to the hard disk capacity and memory capacity carried in the virtual machine request, and because the hard disk capacity and memory capacity carried in the virtual machine request There are various capacities, and users have relatively high demands on the memory capacity used to ensure the ru...

Problems solved by technology

[0003] In the prior art, after receiving the virtual machine request sent by the user through the terminal, the cloud server allocates a virtual machine to the user according to the hard disk capacity and memory capacity carried in the virtual machine request, and because the hard disk capacity and memory capacity carried in the virtual machine request There are various capacities, and users have relatively high demands on the memory capacity used to ensure the running speed, which will cause the following problems: the memory of the physical machine has been allocated, but there is still a lot of capacity left on the hard disk, and due to the The physical resources of the physical machine are used independently of other physical resources, which undoubtedly wastes more hard disk resources of the physical machine

For example: the hard disk capacity of physical machine A is 500G, and the memory capacity is 8G. Assume that the cloud virtual machine requested by user a is: the hard disk capacity is 50G, and the memory capacity is 2G. The cloud virtual machine requested by user b is: hard disk The capacity is 100G, the memory capacity is 2G, and the cloud virtual machine requested by user c is: the hard disk capacity is 200G, and the memory capacity is 4G. At this time, the memory of the physical machine A is fully allocated, but there is still 150G hard disk left. Make the physical machine unable to serve as the physical resource provider of the cloud virtual machine requested by other users

[0004] It can be seen that in the prior art, the physical machine as the physical resource provider of the cloud virtual machine cannot be effectively utilized, and there is a waste of resources, which seriously affects the income of the physical machine
