Embodiment
Please refer to Fig. 1.Fig. 1 is in one embodiment of the invention, a kind of schematic diagram of virtual system 1.Virtual system 1 can comprise load balancer 10, at least one virtual machine 12 and share service assembly 14 in the present embodiment.The share service assembly is as sharing storage space, shared data bank etc.
Please be simultaneously with reference to Fig. 2.Fig. 2 is in one embodiment of the invention, the calcspar of virtual resource adjusting gear 2.Virtual resource adjusting gear 2 comprises: acquisition module 20, judge module 22 and adjusting module 24.In an embodiment, virtual resource adjusting gear 2 can be arranged in aforesaid load balancer 10, adjusts with number and unit resource amount to virtual machine 12.In other embodiment, virtual resource adjusting gear 2 also can only be arranged at the part assembly in load balancer 10 or be independent of the outer running of load balancer 10.
Please be simultaneously with reference to Fig. 3.Fig. 3 is in one embodiment of the invention, the process flow diagram of virtual resource method of adjustment 300.Virtual resource method of adjustment 300 can be applicable in as shown in Figure 2 virtual resource adjusting gear 2.Virtual resource method of adjustment 300 comprises the following step (should be appreciated that, mentioned step, except chatting especially bright its order person, all can adjust its front and back order according to actual needs in the present embodiment, even can carry out simultaneously simultaneously or partly).
In step 301, as shown in Figure 1, provide virtual machine 12 in virtual system 1.These virtual machines 12 will have that maximum reads the load critical value and minimum reads load critical value and maximum computing load critical value and minimum computing load critical value.
Then in step 302, the acquisition module 20 in Fig. 2 will capture read-write charge capacity and the computing load amount in the sum data charge capacity 21 of virtual system 1.Sum data charge capacity 21 is the handled data volume of virtual machine 12.Wherein, sum data charge capacity 21 can be divided into read-write type and arithmetic type by processing mode.Read-write type comprises network access amount and the disk access amount of data being read and write via the mode of disk, network etc.Arithmetic type comprises central processing unit operand and the memory access amount of the access of the computing of central processing unit or internal memory.
In general, the data of read-write type are processed the number be subject to virtual machine 12 and are limit.Therefore less virtual machine 12 can't accelerate the processing of read-write type data due to the number that is subject to FPDP.The data of the arithmetic type unit resource amount to virtual machine 12 are relevant, and when virtual machine 12 has than the central processing unit of multinuclear or larger internal memory, the speed of computing will be accelerated thereupon.
In an embodiment, judge module 22 can be obtained its relevant critical value 23 or be set and can get via the user by virtual machine 12.Therefore, in step 303, judge module 22 will judge that the read-write charge capacity reads load critical value and the minimum relation that reads the load critical value with maximum, and the relation of judgement computing load amount and maximum computing load critical value and minimum computing load critical value.Wherein, the maximum of virtual machine 12 reads the load critical value and the minimum load critical value that reads is the load upper limit and the lower limit that it processes the data of read-write type.If the read-write charge capacity reads the load critical value greater than maximum, represent to read and write this moment charge capacity and can load over 12 of virtual machines.And read the load critical value when reading and writing charge capacity less than minimum, and representing that read and write charge capacity this moment less, the resource of virtual machine 12 is superfluous.Similarly, if the computing load amount greater than maximum computing load critical value, represents that this moment, the computing load amount can be loaded over 12 of virtual machines.And work as the computing load amount less than minimum computing load critical value, and expression computing load amount this moment is less, and the resource of virtual machine 12 is superfluous.
In step 304, adjusting module 24 reads the load critical value according to read-write charge capacity and maximum and the minimum relation that reads the load critical value is adjusted the number of the virtual machine 12 of virtual system 1.And adjusting module 24 is adjusted the unit resource amount of the virtual machine 12 of virtual system according to the relation of computing load amount and maximum computing load critical value and minimum computing load critical value according to the computing load amount.
In an embodiment, adjusting module 24 can be read and write respectively the judgement of charge capacity and computing load amount relevant critical value with it and adjust.For instance, transfer the number that increases virtual machine 12 when adjusting module 24 judgement read-write charge capacity read the load critical value greater than maximum, and increase the unit resource amount of virtual machine 12 when judging the computing load amount greater than maximum computing load critical value.That is to say, when the read-write charge capacity reads the load critical value greater than maximum, the number of virtual machine 12 is increased, when virtual machine 12 may have multiple different unit resource amount, for example different CPU or memory size may be arranged, increasing the mode of virtual machine 12, can be that the virtual machine of selecting to have the least unit stock number in virtual machine 12 carries out the number increase.Yet in another embodiment, adjusting module 24 can comprehensively be read and write charge capacity and carry out more efficient adjustment to the comparative result of computing load amount relevant critical value with it.
Please refer to Fig. 4 A and Fig. 4 B.Fig. 4 A and Fig. 4 B are in one embodiment of the invention, and the virtual resource method of adjustment is to read-write charge capacity more detailed process flow diagram when relevant critical value judges with it to the computing load amount.
In step 401, judge module 22 first reads sum data charge capacity 21, and whether judgement read-write charge capacity reads the load critical value greater than maximum in step 402.When the read-write charge capacity reads the load critical value greater than maximum, judge module 22 will increase flag at step 403 pair number and set.Do not read the load critical value greater than maximum when reading and writing charge capacity, whether judge module 22 further reads the load critical value less than minimum in step 404 judgement read-write charge capacity.When the read-write charge capacity reads the load critical value less than minimum, judge module 22 will downgrade flag at step 405 pair number and set.And do not read the load critical value less than minimum when reading and writing charge capacity, judge module 22 will not set any flag, proceeds directly to step 406.And when aforesaid step 403 and step 405 are completed, also will carry out step 406, again to be written into sum data charge capacity 21.Judge as the aforementioned in flow process, judge module 22 has judged that the number of virtual machine 12 needs to adjust, and the virtual machine 12 after the sum data charge capacity 21 that again is written into namely can change number is taken into account, and proceeds to the A point, with the judgement flow process of hookup 4B.
The flow process of Fig. 4 B is by the beginning of A point, with the flow process of hookup 4A.In step 407, judge module 22 will judge that whether the computing load amount is greater than maximum computing load critical value.Judge as the aforementioned in flow process, judge module 22 has judged that the number of virtual machine 12 needs to adjust, and the maximum computing load critical value of this moment has been the value of 12 the maximum operands that can load of virtual machine after number changes.For instance, be two as original virtual machine 12 numbers, and judge module 22 judged in the flow process of Fig. 4 A that the read-write charge capacity surpasses that 12 of virtual machines can loads and needs to transfer and increased, in step 407 be that virtual machine 12 numbers are the maximum computing load amount of 3 o'clock in order to the maximum computing load critical value that judges.Therefore, the virtual resource method of adjustment can be avoided adjusting simultaneously the wasting of resources that number and unit resource amount cause on the contrary when read-write charge capacity and computing load amount all rise.
Judge module 22 judgement computing load amounts are greater than maximum computing load critical value in step 407, and judge module 22 will increase flag in step 408 pair stock number and set.Not greater than maximum computing load critical value, judge module 22 further judges that in step 409 whether the computing load amount is less than minimum computing load critical value when the computing load amount.Less than minimum computing load critical value, judge module 22 will downgrade flag in step 410 pair stock number and set when the computing load amount.And work as the computing load amount not less than minimum computing load critical value, judge module 22 will not set any flag, and proceeds directly to step 411.When aforesaid step 408 and step 410 are completed, also will carry out step 411, to produce judged result.
Please refer to Fig. 5 A and Fig. 5 B.Fig. 5 A and Fig. 5 B are in one embodiment of the invention, the process flow diagram that the virtual resource method of adjustment is adjusted virtual machine.In step 501, adjusting module 24 will read judged result.In step 502, whether adjusting module 24 will judge that number is transferred and increase flag or stock number and transfer and increase flag and be set.As be set, will judge in step 503 adjusting module 24 whether the resource of whole virtual system is enough.As deficiency, in step 504, adjusting module 24 will not carry out any adjustment.As enough, adjusting module 24 will judge in step 505 whether the virtual machine number is enough again.Needing when the virtual machine number deficiency increases, and adjusting module 24 will copy existing one of them virtual machine in step 506, producing a new virtual machine, and proceeds to the B point, with the flow process of hookup 5B.And as sufficient in step 505 judgement virtual machine number in adjusting module 24, proceed directly to the B point, with the flow process of hookup 5B.
Adjusting module 24 judgement numbers are transferred and are increased flag or stock number and transfer and increase flag and be not set in step 502, will judge in step 507 that number downgrades flag or stock number and downgrades flag and whether be set.As be not set, flow process is with execution in step 504, and adjusting module 24 does not carry out any adjustment.As be set, will judge in step 508 adjusting module 24 whether virtual machine 12 has reached minimal amount.As reaching minimal amount, flow process is with execution in step 504, and adjusting module 24 does not carry out any adjustment.As do not reach minimal amount, proceed to the B point, with the flow process of hookup 5B.
The flow process of Fig. 5 B is by the beginning of B point, with the flow process of hookup 5A.In step 509, adjusting module 24 will be adjusted according to flag the unit resource amount of virtual machine 12, and select entity apparatus in step 510, to be provided in the needed actual resource of virtual machine 12 newly-increased in step 511.Then in step 512, virtual machine 12 will upgrade its existing critical value parameter, so that the maximum that acquisition module 20 can obtain to upgrade reads the load critical value and minimum reads load critical value and maximum computing load critical value and minimum computing load critical value.
Therefore, virtual resource adjusting gear of the present invention and virtual resource method of adjustment except can be for different data types, be carried out outside the adjustment of the number of virtual machine and/or stock number, and also reference is the most effectively adjusted mutually, to avoid the waste of resource.

Therefore, as shown in Figure 6, the horizontal number that is adjusted into for virtual machine carries out, and carries out and be adjusted into longitudinally for the unit resource amount of virtual machine.In an embodiment, when virtual system 1 has plural virtual machine 12, and when the read-write charge capacity of virtual system 1 reads the load critical value greater than the maximum of virtual machine 12 integral body, the port that means read-write due to the read-write charge capacity is not enough, therefore number is transferred to increase to get final product, do not need the calculation resources amount is promoted too much.Therefore adjusting module 24 can preferentially make the number that has minimum unit resource amount person in virtual machine 12 increase.
In an embodiment, when virtual system 1 has plural virtual machine 12, and the computing load amount of virtual system 1 is during greater than the maximum computing load critical value of virtual machine 12 integral body, and adjusting module 24 can make the unit resource amount that has maximum unit resource amount person in virtual machine 12 increase again.Therefore, preferentially increase the unit resource amount of unit resource amount the greater, can guarantee that the resource that increases newly is enough to deal with required charge capacity.
In an embodiment, has the virtual machine 12 that has different unit resource amounts more than two when virtual system 1, and when the read-write charge capacity of virtual system 1 reads the load critical value less than the minimum of virtual machine 12 integral body, be the inadequate resource of avoiding causing when larger unit resource amount person closes having in virtual machine 12, so adjusting module 24 can make preferentially the number that has minimum unit resource amount person in virtual machine 12 reduce.
In an embodiment, has the virtual machine 12 that has different unit resource amounts more than two when virtual system 1, and the computing load amount of virtual system 1 is during less than the minimum computing load critical value of virtual machine 12 integral body, be the inadequate resource of avoiding causing when larger unit resource amount person closes having in virtual machine 12, adjusting module 24 can preferentially make the unit resource amount that has minimum unit resource amount person in virtual machine 12 reduce.
Therefore, virtual resource adjusting gear of the present invention and virtual resource method of adjustment except can be for different data types, be carried out outside the adjustment of the number of virtual machine and/or stock number, also can provide according to the characteristic of stock number different adjustment trend, to avoid the waste of resource.
