The resource that second business occupies is recycled.The concrete mode of the recycling can be that the partial virtual machine for making the second business occupy is stopped
Sleep or close etc..Wherein, virtual machine is the main body that resource is occupied in system, and a virtual machine can occupy a certain number of resources.
Wherein, the second business can be that resource allocation device is randomly selected in the business of multiple the allocated resources,
Can also be that selection, such as the priority etc. of business are carried out according to certain selection rule.
In the resource that second business that recycles occupies, recovery section resource, rather than the whole for recycling the second business accounts for
It with resource, at least needs to ensure after recycling the part resource, the resource that the second business occupies is not less than preset the
The reserved resource of two business.Reserved resource is the configuration parameter for each business of resource allocation device configuration, the reserved resource
It is the minimum of resources for being each delineation of activities in advance, may include that CPU reservation resource and memory reserve resource, which can be with
For the normal operation of business, which is indicated with R.
Above-mentioned " first ", " second " are only to distinguish different business, not refer in particular to or limit.
Step 104, the part resource of the second business of recycling is distributed into first business.
After Resource recovery, resource allocation device by the resource part of recycling or can be fully allocated to the first business, have
The stock number needs of body distribution are determined according to the resource and the required resource of the first business of recycling.Each business specifically may be used
To be realized by virtual machine.It can be specifically the virtual machine for starting or waking up certain specification for the first traffic assignments resource.
In the embodiment of the present invention, after receiving resource allocation request, if surplus resources are inadequate, business occupancy is adjusted
Resource, and according to service request distribute resource service quality has been ensured by the linkage of above-mentioned business demand and resource pool,
Improve the utilization rate of resource.
For example, the second business is related to one or more specific services, for example web services, database service, storage takes
Business etc., resource allocation device are second traffic assignments, 30 virtual machines, wherein 10 for handling web services, 10 with
In processing data bank service, 10 for handling data storage service.It is the to receive Client-initiated in resource allocation device
After the request of one traffic assignments resource, when find the surplus resources in resource pool be less than threshold value when, the resource allocation device according to
The resource that second business occupies is adjusted to 15 by multiplex strategy, wherein 5 are used to handle web services, and 5 for handling number
According to library business, 5 are used to handle data storage service, at least to ensure the reserved resource in multiplex strategy for the second business configuration
(as at least ensured 2 virtual machine processing web services, 2 are used to handle data bank service, and 2 for handling data storage clothes
Business).Then, which can be by the part resource recycled from the second business namely 15 virtual machine parts or complete
Part is assigned to the first business.
In another embodiment of the invention, following parameter can be configured in resource allocation device：
For the configuration parameter of entire resource pool：
Buffer resource, the resource bid for distributing to certain burst services, the burst service such as Client-initiated are virtual
Machine（Virtual Machine, VM）It wakes up.When unappropriated resource is less than pre-set buffer resource threshold B in buffer resource, meeting
Trigger the reclaimer operation of resource.
For business configuration parameter, such as reserved resource of aforementioned each business.
In this embodiment, whether the surplus resources for judging resource pool are less than threshold value, can specifically include：
Whether the total resources for judging resource pool and the difference of resource occupation total amount are less than threshold value, wherein resource occupation is total
Amount is the sum of the resource occupation amount of buffer resource and each service resources occupancy.If being less than threshold value, then execute in an embodiment
Step 103.
In another embodiment of the invention, the configuration parameter for business being arranged in resource allocation device can also wrap
It includes：
The resource maximum usage amount of business, hereinafter abbreviation M.It cannot exceed the limitation for the resource of each traffic assignments, it should
Resource maximum usage amount can specifically include the resource maximum usage amount of memory and the resource maximum usage amount of CPU, and two resources are most
The default value of big usage amount is ∞, but be not restricted to that the resource maximum usage amount of the resource maximum usage amount of memory and CPU.
The priority of each business, hereinafter abbreviation P.Priority can be divided into high, medium and low three grades.When occur resource not
When sufficient, under the premise of ensureing the reserved resource of each business, the higher business of priority can unconditional preempting priority compared with
The resource beyond reserved resource part of low business.
The weight of resource occupation in grade business that All factors being equal, preference will be give to, hereinafter abbreviation W.The resource that the bigger expression of W values can occupy
It is more.When inadequate resource occurs, business is selected to carry out resource reclaim according to weight.
Constraint：The sum of R of all business is less than the total available resources quantity of resource pool.
Resource allocation policy in resource allocation device can be：
The business of first-come first-served basis, first to file first obtains resource from resource pool；
The resource of each traffic assignments is no more than the resource maximum usage amount M of business；
Each business is arranged and reserves resource, for ensureing that the R values of business can be met under any circumstance.
When starting resource reclaim, P, W, R selection business can be considered and carry out resource reclaim；
Between the business of different priorities, high-priority service is other than ensureing the reserved resource R of low priority traffice, energy
Unconditionally seize other resources；Share available resources in proportion between same priority business.
Buffering section when buffer resource is as burst service application resource, when unappropriated resource is few in buffer resource
Resource reclaim is triggered when threshold value B, resource reclaim can be specifically carried out from each business.
Wherein, above-mentioned strategy can configure execution condition, such as come into force, periodically come into force（When entry-into-force time, failure
Between）, the period comes into force（Entry-into-force time, out-of-service time）Deng, support using day be the period periodically.
Resource allocation device can be defaulted as coming into force, and the out-of-service time can also be arranged, and can start simultaneously multiple multiple
With the timed task of strategy, but the multiplex strategy that comes into force of a moment can only there are one.In the execution of configuration multiplex strategy
When the time, which can detect each multiplex strategy and execute whether the time repeats, and need to change executing the time when repeating,
Or stop the multiplex strategy being currently running.Multiplex strategy enters IN_TIMING (in timing) state after starting, when multiplex strategy arrives
Up to after the entry-into-force time, strategy comes into force migration for EFFECTIVE（Effectively）State.When being configured to immediately or when timing, multiplex strategy
It is automatically stopped after reaching the out-of-service time, multiplex strategy state empties.It is executed if it is the period, after multiplex strategy reaches the out-of-service time
IN_TIMING (in timing) state is returned in state transition.
In another embodiment of the invention, based on the parameter configuration in above-mentioned resource allocation device, as shown in Fig. 2,
Before the part resource that the second business of the recycling occupies, this method can also include the process for selecting above-mentioned second business, should
Process may include：
Step 201, it is determined whether there are the business that priority is less than first service priority.
According to the priority of preset each business, it is low to determine whether that there are priority first for resource allocation device
In the business of the priority of first business, if it is present step 202 is executed, if it does not exist, then executing step 203.
Step 202, select the priority less than the business of first service priority as second business.
If there are the business of low priority, select at least one business as above-mentioned second in the business of low priority
Business that is, when inadequate resource occurs, is ensureing each priority service according to the preset priority rule of resource allocation device
Resource using resource is reserved under the premise of, priority it is higher can the unconditional relatively low business of preempting priority beyond reserved
The resource of resource part recycles the part resource that the second business of selection occupies.
Step 203, select at least one business as second business, the ad eundem business in ad eundem business
In each business priority it is identical as the priority of the first business.
If low priority traffice is not present, with randomly choosed in the business of the first business All factors being equal, preference will be give to grade it is at least one
Business selects at least one business to make as above-mentioned second business, or according to the weight of resource occupation in All factors being equal, preference will be give to grade business
For above-mentioned second business, for example, selecting the highest business of resource occupation weight as above-mentioned second in All factors being equal, preference will be give to grade business
Then business recycles the part resource that the second business selected occupies.
In another embodiment, as shown in figure 3, should select at least one business as the second business in ad eundem business
Method can specifically include：
Step 301, the difference of the first ratio and the second ratio of each business in the ad eundem business is calculated.
First ratio is the resource amount of overflowing of each business in the ad eundem business in the ad eundem business
Shared ratio in the resource amount of the overflowing summation of all business.The resource amount of overflowing is each business in the ad eundem business
The practical difference occupied between resource and reserved resource.
Assuming that the practical occupancy resource of business i is N in the ad eundem businessi, then resource out of range value is Ni-Ri, business i
The first ratio beWherein, i=1,2 ... n, n are natural number.
Second ratio is the resource occupation of resource occupation weight all business in the ad eundem business of business
Shared ratio in weight summation, wherein the resource occupation weight is preset value.
The second ratio of business i isWherein, i=1,2 ... n, n are natural number.
Step 302, select the business corresponding to the maximum value of the difference of first ratio and the second ratio as described in
Second business.
If first ratio of each business and the difference of the second ratio are identical in ad eundem business, in ad eundem industry
It is randomly choosed in business at least one as above-mentioned second business.
Such as：1 P of business1=low W1=30 R1=10；
2 P of business2=low W2=70 R2=50
It is practical to occupy resources measurement：Business 1 is practical to occupy resource N1=20
Business 2 is practical to occupy resource N2=90
Service resources out of range value：Business 1 is (N1-R1The business of)=10 2 is (N2-R2)=40
Wherein, i=1,2 ... n, n are natural number.
The latter is more than the former, therefore business 2 is selected to carry out resource reclaim as above-mentioned second business.
In an alternative embodiment of the invention, when computationally stating the first ratio of each business in ad eundem business, wherein
It is practical to occupy the linear weighted function value that resource be the practical occupancy resource of CPU and the practical occupancy resource of memory, it is denoted as first
Weighted value；Reserved resource can be the linear weighted function value between the reserved resource of memory and the reserved resource of CPU, be denoted as second and add
Weights.The resource amount of overflowing is the difference between above-mentioned first weighted value and the second weighted value.
Wherein, Ni=x*Ni(cpu)+y*Ni(MEM), Ri=x*Ri(cpu)+y*Ri(MEM), x and y are respectively the weighting of CPU and memory
Coefficient, default situations can be disposed as 1, Ni(cpu)For the practical occupancy resource of the CPU of business i, Ni(MEM)For the memory of business i
It is practical to occupy resource, Ri(cpu)For the reserved resource of the CPU of business i, Ri(MEM)For the reserved resource of the memory of business i；Each business
The unit of CPU be unified into MHz, it is natural number that the unit of memory, which is unified into MB, i=1,2 ... n, n,.
For example, it is assumed that there are two business in resource pool：Business 1 and business 2, four parameter such as tables of two business configurations
Shown in 1：
1 multiplex strategy parameter configuration (one) of table
By resource allocation principle, since the priority of business 1 is higher than the priority of business 2, except guarantee business 2
For reserved resource R outside, surplus resources are all preferential to ensure that business 1 uses.The resource that business 1 does not use can distribute to business
2 use, but when business 1 needs, it is necessary to recycle.
Assuming that resource pool, there are business 1,2 and 3, four parameters of each business configuration are as shown in table 2：
2 multiplex strategy parameter configuration (two) of table
1 preemption of resources of business of high priority, but the resource that business 1 does not use can distribute to business 2, business 3
It uses, business 2 and business 3 distribute surplus resources by weight proportion.
When business 1 triggers resource reclaim, aforementioned first ratio is preferentially selected to the resource reclaim of ad eundem business 2, business 3
Business Resource recovery corresponding with the maximum value of the second proportional difference, until respectively reaching reserved resource R.
If business 2 is practical to occupy resource N2=x*400MHz+y*1000MB；Reserved resource R2=x*200MHz+y*500MB
Business 3 is practical to occupy resource N3=x*150MHz+y*450MB reserves resource R3=x*100MHz+y*300MB
Wherein, x=1, y=1
Wherein, i=1,2 ... n, n are natural number.
The former is more than the latter, therefore, the former is preferentially selected business 2 to carry out resource reclaim.
The embodiment of the present invention supports different business shared resource pond within the same period, realizes part to different business
Volume controls, and in resource contention, realizes coordination, the recycling of resource between different business, can be full by being flexibly arranged
The resource requirement of sufficient different business.
The resource allocation device is divided by the priority and resource occupation weight of setting business in the resource of prerequisite variable
With under principle, ensure that particular service weighs the Special use of resource.The resource allocation device, which uses, is based on priority and resource
Two kinds of strategies for occupying weight, can meet different business demands, also, can be to different priority in resource reclaim
Different degrees of Resource Guarantee is carried out with the business of weight.
In another embodiment of the invention, when carrying out resource reclaim to the second business, it is reserved that each business can be met
The limitation of resource cannot continue resource reclaim when business occupancy resource reaches reserved resource.
Can also carry out expanding volume reduction automatically inside each business, for example, when some business occupancy a certain virtual machine CPU or
Memory usage is more than some threshold value, which can submit the request of dilatation, i.e. request distributes new resource, when less than some threshold
When value, the request of volume reduction, such as suspend mode or the certain virtual machines of closing can be submitted, to discharge resource.Resource reclaim between business
It will be prior to the automatic dilatation inside business, that is to say, that when device carries out resource reclaim between certain business, temporarily stop
The only automatic dilatation inside these business, until resource reclaim terminates, and continuous three periods judge resource abundance, can just put
The dilatation operation for opening the business, to avoid concussion.Under extreme case, low priority traffice can be constantly in dilatation final state,
More resources can not be obtained.
When carrying out resource reclaim, the resource recycled every time can be as unit of virtual machine, wherein virtual machine selects at random
It selects, business oneself is needed to ensure the reliability of business.
In another embodiment of the invention, the part resource of recycling is distributed into the first business in resource allocation device
Afterwards, it can further include：
When the resource occupation time of first business reaches preset time, executing reduces the reserved of first business
Resource.
The embodiment of the present invention also supports different business to use time-sharing multiplex mode, and section is respectively started not in different times
With the virtual machine of business, achieve the purpose that efficiently to utilize resource.
Such as there are business 1 and business 2 in resource pool, the priority of business 1 is higher than the priority of business 2, therefore presses
The principle of resource allocation will preferentially meet the resource request of business 1 under the premise of ensureing the reserved resource of two business.
Assuming that some user group, it to be significantly more than the use to business 2 to the use of business 1 on daytime, and to evening
The fact that upper, is mitigated, no longer so much to the use of business 1.Can be business 1 and business according to this actual conditions
2 configure different reserved resources in different time sections, for example, when the resource occupation time of business 1 reaches preset time, reduce
The reserved resource of business 1.
Specifically, a multiplex strategy 1 can be created, upper two business are associated with, are business 1 and business 2 respectively, setting is multiple
It it is daytime 9 with the execution time in the period of strategy 1:00-18:00, concrete configuration parameter is as shown in table 3：
It creates a multiplex strategy 2 and is associated with two business 1 and business 2, equally correspond to business 1 and business 2 respectively, set
The period of multiplex strategy 2 executes the time as at night 18:00-9:00, concrete configuration parameter is as shown in table 4, due at night by industry
The reserved resource R of business 1 is turned down, and such business 2 can share more resource, to improve whole resource multiplex
Rate.
