The embodiment of the invention provides one kind to carry out stretch-processing method to virtual application server 130 in cloud computing, This method can be total to by the management equipment 110 of virtual application server 130, load balancer 120 and virtual application server 130 With realization.The solution of the present invention can be applied in some service groups, and virtual application service explained below belongs to same Service groups, the present embodiment are illustrated for handling some service groups, by the invention it is possible to service groups into The flexible processing of row.As shown in Figure 1, being the system framework figure of the present embodiment.
As shown in figure 5, the process flow of this method can be such that
Step 501, management equipment 110 receives the load condition message that at least one virtual application server 130 is sent.
In an implementation, flexible proxy module can be set in each virtual application server 130 in service groups, this is flexible The current load condition of affiliated virtual application server 130 can be periodically obtained in proxy module 131, then can be incited somebody to action The load condition got is compared with pre-stored load status threshold, determines corresponding load condition message.Wherein, Load condition can be CPU usage, user's access number in the unit time and memory usage etc..Load condition disappears Breath may include overload message, light condition disappears and normal condition message.It can be carried in load condition message above-mentioned Load condition can also carry characterization overload, underloading or normal status indicator.It is identified as with load condition message carrier state , the status indicator in overload message can be grow, and the status indicator in light condition message can be shrink, just Status indicator in normal status message can be none.In addition, virtual application server can also be carried in load condition message 130 mark.
Status indicator (such as voting tag) can be stored in advance in virtual application server 130, it is at the beginning, each virtual The status indicator that application server 130 stores is none.Flexible proxy module 131 may determine that whether current loading condition surpasses The overload state upper limit, or whether it is lower than load condition lower limit.It can store load condition threshold in flexible proxy module 131 Value, which may include the load condition upper limit and load condition lower limit.Flexible proxy module 131 determines that load condition is more than negative When the load state upper limit, it is determined that corresponding load condition message is overload message, then can be by local status indicator It is revised as grow, and overload status message can be sent to flexible engine 111, overload message can be identified with carrier state grow.When flexible proxy module 131 determines that load condition is lower than load condition lower limit, it is determined that corresponding load condition message is Then local status indicator can be revised as shrink, and can send and be lightly loaded to flexible engine 111 by light condition message Status message, light condition message can identify shrink with carrier state.Flexible proxy module 131 determines that load condition is loading When between the state upper limit and load condition lower limit, it is determined that corresponding load condition message is normal status message, then can be with Without processing.
It can also be stored in advance in service groups in flexible engine 111, the status indicator of each virtual application server 130, When initial, the status indicator of each virtual application server 130 is none.Flexible engine 111 receives some virtual application clothes The load condition message that business device 130 is sent, then can repair the corresponding status indicator of virtual application server 130 Change, so as to it is subsequent in step 505, stretch engine 111 it is available into service groups, in addition to the first virtual application server Other virtual application servers load condition message.
Step 502, management equipment 110 determines that the quantity of the overload message in the load condition message received meets Default report condition, or determine that the quantity of the light condition message in the load condition message received meets default report condition When, notice is reported to the transmission of the second virtual application server of not sent load condition message.
Wherein, the second virtual application server refers to that flexible engine 111 determines the quantity of the overload message received When the quantity of the default report condition of satisfaction or light condition message meets default report condition, not sent load condition in service groups The virtual application server of message.
In an implementation, report condition can be preset in flexible engine 111, flexible engine 111 receives load condition After message, the quantity or the underloading in load condition message that can judge the overload message in load condition message respectively Whether the quantity of status message meets default report condition, if it is satisfied, then flexible engine 111 can be to not sent load condition The second virtual application server transmission of message reports notice.Default report condition can be diversified, and the present embodiment mentions Following several feasible modes are supplied.
As a kind of optional way of report condition, flexible engine 111 can receive a virtual application server When the overload message or light condition message of 130 transmissions, into service groups belonging to the virtual application server 130 The transmission of other virtual application servers 130 reports notice, to obtain in service groups, in addition to the virtual application server 130 The load condition message of other virtual application servers 130.
As the another alternative of report condition, flexible engine 111 determines the mistake in the load condition message received The quantity of load status message proportion in the total quantity of load condition message is greater than the first preset threshold, alternatively, flexible draw It holds up 111 and determines the quantity of light condition message in the load condition message that the receive institute in the total quantity of load condition message Accounting example is greater than the first preset threshold.
It in specific implementation, can be in computational load status message after the engine 111 that stretches receives load condition message Underloading shape of the quantity of overload message in the total quantity of load condition message in proportion and load condition message The quantity of state message proportion in the total quantity of load condition message.Wherein, the total quantity of load condition message can be The quantity for the virtual application server 130 that service groups are included.Flexible engine 111 may determine that whether light condition ratio is greater than First preset threshold can be to the of not sent load condition message if calculated ratio is greater than the first preset threshold The transmission of two virtual application servers 130 reports notice, if calculated ratio is respectively less than the first preset threshold, can not send out Serve report notice.For example, the first preset threshold can be 40%, then the quantity of overload message is shared in above-mentioned total quantity Ratio be more than 40% or light condition message quantity in above-mentioned total quantity proportion be more than 40%, then can Xiang Weifa It send the second virtual application server 130 of load condition message to send and reports notice.
As the another alternative of report condition, flexible engine 111 determines the mistake in the load condition message received The quantity for carrying status message is greater than the second preset threshold, alternatively, flexible engine 111 determines in the load condition message received The quantity of light condition message is greater than the second preset threshold.
It in specific implementation, can be by the mistake in load condition message after the engine 111 that stretches receives load condition message The quantity for carrying status message is compared with the second preset threshold, can also be by the light condition message in load condition message Quantity is compared with the second preset threshold, if flexible engine 111 determines that the quantity of the overload message received is greater than Second preset threshold, alternatively, flexible engine 111 determines that the quantity of the light condition message received is greater than the second preset threshold, It can then be sent to the second virtual application server 130 of not sent load condition message and report notice.If flexible engine 111 The quantity of the quantity and light condition message that determine overload message can not then be sent no more than the second preset threshold Report notice.For example, sharing 8 virtual application servers 130 in service groups, the second preset threshold can be 3, overload message Quantity be more than 3 or the quantity of light condition message be more than 3, then can be sent to the second virtual application server 130 report it is logical Know.
Step 503, management equipment 110 obtain send report notice after not sent load condition message in preset duration The last load sent of load balancing weight and the first virtual application server 130 of first virtual application server 130 Status message.
Wherein, the first virtual application server can be in above-mentioned second virtual application server, after transmission reports notice The virtual application server of interior not sent load condition message when preset duration.
In an implementation, after the engine 111 that stretches reports notice to the transmission of the second virtual server, timing can be started, stretched Engine 111 can receive the load condition message of the transmission of virtual application server 130, and can recorde and sent load condition and disappear The virtual application server 130 of breath.When reaching preset duration, flexible engine 111 can determine not sent load condition message The first virtual application server 130.The load balancing power of the flexible available first virtual application server 130 of engine 111 Value and the last load condition message sent of the first virtual application server 130 may comprise steps of:
Step 1: flexible engine 111 sends request of data to load balancer 120, the first void is carried in request of data The mark of quasi- application server 130.
In an implementation, when reaching preset duration, the engine 111 that stretches determines that the first virtual application server 130 is not sent Then load condition message can send request of data to load balancer 120, carry first in the request of data and virtually answer With the mark of server 130.
Step 2: the flexible engine 111 that load balancer 120 receives the management equipment 110 of virtual application server 130 is sent out The request of data sent.
Step 3: load balancer 120 obtains load balancing power corresponding with the mark of the first virtual application server 130 Value and the last load condition message sent of the first virtual application server 130, to 110 transmission load balancing of management equipment Weight and load condition message.
In an implementation, virtual application server 130 periodically can send load condition to load balancer 120 and disappear Breath, so that load balancer 120 is the distribution load balancing weight of virtual application server 130 in service groups.Load balancer 120 can store the mark of each virtual application server 130 in service groups, and each virtual application server 130 is corresponding to be loaded The load condition message that weighing apparatus weight and each virtual application server 130 are sent.It can be carried in the load condition message above-mentioned Load condition, load condition can be CPU usage, user's access number in the unit time and memory usage etc..It is negative After load balanced device 120 receives request of data, the mark of the first virtual application server 130 in available request of data, Then the corresponding load balancing weight of the first virtual application server 130 and the first void can be obtained in the data of storage The last load condition message sent of quasi- application server 130, then sends the load balancing weight to flexible engine 111 With the load condition message.
Step 4: flexible engine 111 receive the first virtual application server 130 the corresponding load balancing weight of mark and The last load condition message sent of first virtual application server 130.
Step 504, management equipment 110 is virtual according to the load balancing weight of the first virtual application server 130 and first The last load condition message sent of application server 130, determines the current load shape of the first virtual application server 130 State.
In an implementation, it can be sent in flexible engine 111 with load balancing weight according to the pre-stored data, the last time negative The corresponding relationship of status message and current load condition message is carried, which can be configured by technical staff, skill Can also the threshold value of load balancing weight be arranged in the above correspondence relationship in art personnel, to divide the grade of load balancing weight, For example, the range of load balancing weight is 0~5, the threshold value of load balancing weight is 2 and 4, then load balancing weight (0,2] In range, it is believed that be it is low, load balancing weight is in (2,4) range, it is believed that in being, load balancing weight is in [4,5] model In enclosing, it is believed that it is height, by the setting of threshold value, can be convenient flexible engine 111 and judged.Flexible engine 111 can root It is sent according to the load balancing weight and 130 the last time of the first virtual application server of the first virtual application server 130 negative Status message is carried, corresponding load condition is searched in the corresponding relationship, obtains current negative of the first virtual application server 130 Load state.Wherein, the last load condition message sent can be obtained from load balancer 120, and the last time sends Load condition message in can carry load condition,
The load condition in load condition message sent using the last time is CPU usage, the range of load balancing power For 0~5, which can be as shown in Table 1:
Table one
For example, the load balancing weight of the first virtual application server 130 is 4, the load condition that the last time sends disappears In breath, CPU usage 70% can then determine the current load condition message of the first virtual application server 130, to carry The load condition message of grow.
Optionally, service provider can preset the operating mode of service groups, accordingly.Step 504 processes Journey can be such that the operating mode information for obtaining current setting, operating mode information include that resource utilization is preferential or processing is fast Degree is preferential；Load balancing weight according to the pre-stored data, the last load condition message sent, operating mode information and work as The load balancing weight of the corresponding relationship of preceding load condition message and the first virtual application server 130, first virtually answer With the operating mode information of server 130 the last the load condition message sent and current setting, determine that first virtually answers With the current load condition message of server 130.
In an implementation, for service provider to preset the operating modes of service groups, flexible engine 111 is available and deposits Operating mode information is stored up, operating mode information can be preferential for resource utilization or processing speed is preferential.It can in flexible engine 111 With pre-stored load balancing weight, the last load condition message, operating mode information and the current load sent The corresponding relationship of status message.Wherein, the last load condition message sent can be obtained from load balancer 120, Load condition can be carried in the load condition message that the last time sends, in the load condition message sent with the last time Load condition be CPU usage for, which can be as shown in Table 2:
Table two
For example, the load balancing weight of the first virtual application server 130 is 3, the load condition that the last time sends disappears In breath, CPU usage 70%, if flexible engine 111 determines that the current operating mode information of service groups is resource utilization Preferentially, then it can determine the current load condition message of the first virtual application server 130, disappear to carry the load condition of none Breath can determine the first void if flexible engine 111 determines that the current operating mode information of service groups is that processing speed is preferential The current load condition message of quasi- application server 130, for the load condition message for carrying grow.
Step 505, the load condition message current according to the first virtual application server 130 of management equipment 110, Yi Jiqi The current load condition message of its virtual application server 130 carries out flexible processing.
In an implementation, it is based on above-mentioned processing, the available all virtual application services into service groups of engine 111 of stretching The current load condition message of device 130.Flexible engine 111 determines that the current load condition of the first virtual application server 130 disappears It, can be according to the current load condition message of the first virtual application server 130 and other virtual application servers after breath 130 current load condition message, determine whether service groups meet default flexible condition.Wherein, other virtual application servers 130 refer in service groups, other virtual application servers 130 in addition to the first virtual application server 130.If service groups Meet preset flexible condition, then the engine 111 that stretches can be sent to virtual application server manager 112 increases or decreases void Intend the request message of application server 130, the number for increasing or decreasing virtual application server 130 can be carried in the request message Amount, and need to increase or decrease the mark of the service groups of virtual application server 130.Virtual application server manager 112 In can store corresponding 130 list of virtual application server of each service groups and multiple not used virtual application servers 130 mark, if receiving the request message for increasing the quantity of virtual application server, virtual application server manager The mark of these virtual application servers, is added to the void of service groups by the new virtual application server of 112 starting corresponding numbers In quasi- application server list；If receiving the request message for reducing the quantity of virtual application server 130, virtual application 130 list of virtual application server of the available service groups of server manager 112 therefrom selects virtually answering for corresponding number With server 130 and these virtual application servers 130 are terminated, by the mark of these virtual application servers 130 from the business It is deleted in application 130 list of virtual application server of group.Virtual application server manager 112 can will increase or decrease The mark of virtual application server 130 is sent to flexible engine 111, and the engine 111 that stretches updates corresponding to the service groups virtual 130 list of application server is updated.Then, stretching engine 111 can be to each virtual application in updated service groups Server 130 sends state and changes message, so that each virtual application server 130 in service groups is by the voting tag of itself It is revised as none.
Optionally, presetting flexible condition may include default increase condition and default reduction condition, correspondingly, step 505 Treatment process can be such that determine the current load condition message of the first virtual application server 130 and other virtually answer With in the current load condition message of server 130, the quantity of overload message meets default increase condition, then increases virtual The quantity of application server 130；Alternatively, determine the current load condition message of the first virtual application server 130 and other In the current load condition message of virtual application server 130, the quantity of light condition message meets default reduction condition, then subtracts The quantity of few virtual application server 130.
In an implementation, flexible measurement can be stored in advance in flexible engine 111, the engine 111 that stretches can be virtual first The current load condition message of application server 130 and the current load condition message of other virtual application servers 130 In, determine the quantity of overload message, and then judge whether the quantity of overload message meets default increase condition, if Meet, is then accelerated according to pre-set virtual application server in flexible strategy, carry out increasing virtual application service The processing of the quantity of device 130 otherwise can be without the processing of the quantity of increase virtual application server 130.Flexible engine 111 can also be in the current load condition message of the first virtual application server 130 and other virtual application servers 130 In current load condition message, the quantity of light condition message is determined, and then judge whether the quantity of light condition message is full The default reduction condition of foot, if it is satisfied, then according to the reduction quantity of pre-set virtual application server in flexible strategy, into Row reduces the quantity processing of virtual application server 130, otherwise, can be without the quantity of reduction virtual application server 130 Processing.Default increase condition and default reduction condition can be diversified, and several feasible processing modes are provided below.
