The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.
Example one
Referring to fig. 2, an embodiment of the present invention provides a method for modifying a load balancing weight value, applied to a load balancing weight processing system, including:
step 101: obtaining M appointed virtual servers input by a first user, wherein M is an integer greater than or equal to 1;
the specified virtual server can be understood as: the user needs a virtual server that modifies the weight values. During the execution of this step, the user may input the M designated virtual servers through various input devices. For example: the mode of keyboard input, the mode of touch panel input, the mode of voice input and the mode of remote wireless signal input can be adopted. In the prior art, there are various means and methods for inputting the above data, which are not described herein for the sake of brevity,
for example, the user may enter the following data in this step: the virtual server is designated as: a server and b server.
Step 102: sending the M designated virtual servers to a preset cloud system, so as to determine that the load balance using the M designated virtual servers is a first load balance through query of the preset cloud system, and determine that the N load virtual servers used in the first load balance and a current weight value corresponding to each load virtual server respectively, wherein N is an integer greater than or equal to M;
the number of the first load balances can be one or more, and each first load balance can respectively and correspondingly use different virtual server groups. That is, the N load virtual servers may serve as all the virtual servers used by the first load balancing. When the first load balance is Z, the number of the N load virtual servers may be Z × N.
In the execution process of this step, the load balancing weight processing system may forward the M designated virtual servers to a cloud control system. And then, the cloud control system queries and obtains first load balances using the M specified virtual servers, each virtual server group (namely the N load virtual servers) used by the first load balance respectively and a current weight value corresponding to each virtual server group respectively, and feeds back the information data to the load balance weight processing system.
It should be noted that the virtual server group obtained by querying in this step is all the virtual servers used by each first load balancing, and there is no case where a part of the virtual servers used by each first load balancing is obtained by querying.
The implementation example of this step is as follows: bearing the above example, when the load balancing weight processing system assigns "the virtual server is: after the server a and the server b are sent to a preset cloud system (which may be an ali cloud system), the preset cloud system may first obtain: the load balancing using the server a and the server b simultaneously comprises a first load balancing and a second load balancing (both the first load balancing are performed), and the load virtual server used by the first load balancing comprises: the server A comprises a server A, a server B and a server C, wherein the current weight value corresponding to the server A is 10%, the current weight value corresponding to the server B is 40%, and the current weight value corresponding to the server C is 50%; the load virtual server used by the load balancing comprises: the system comprises a server a, a server b, a server d and a server e, wherein the current weight value corresponding to the server a is 20%, the current weight value corresponding to the server b is 10%, the current weight value corresponding to the server d is 40%, and the current weight value corresponding to the server e is 30%; and then feeding the data information back to the load balancing weight processing system.

when the step is executed, the user can input N modified weighted values corresponding to each first load balance according to the requirement; or the system can automatically determine the rest modified weight values according to a preset method on the basis that the user only inputs part of the modified weight values. The preset method complies with the following principle: the sum of the weighted values of the load virtual servers used by each first load balance does not exceed 1. Based on the principle, the technical scheme in the embodiment of the application can adjust the weight values of other load virtual servers correspondingly involved in each first load balance on the basis of modifying and adjusting the modified weight values input by the user, so that the N modified weight values which accord with a natural rule and meet the user requirement are obtained.
It should be noted that, in this step, not only the N modified weight values but also a one-to-one correspondence relationship between each load virtual server and each modified weight value is determined.
The step is executed as follows: after receiving the above example, after the load balancing weight processing system receives the relevant query information fed back by the preset cloud system, the user may input the corresponding N modified weight values for the first load balancing by: the modified weight value corresponding to the server a is 20%, the modified weight value corresponding to the server b is 30%, and the modified weight value corresponding to the server c is 50%; the N modified weighted values corresponding to the load balancing input of the second node are as follows: the modified weight value corresponding to the server a is 40%, the modified weight value corresponding to the server b is 20%, the modified weight value corresponding to the server d is 30%, and the modified weight value corresponding to the server e is 10%. Certainly, in the process, the user can also input the modified weight values of the server a and the server b corresponding to the load balancing a and the load balancing b respectively, and the system can automatically adjust the modified weight values of other servers on the basis that the sum of the N modified weight values corresponding to each load balancing does not exceed 1. Therefore, N modified weight values corresponding to the first load balance and N modified weight values corresponding to the second load balance are obtained.
Step 104: and sending the N load virtual servers, the N modified weight values and the corresponding relation between each load virtual server and each modified weight value to the preset cloud system, so that the preset cloud system modifies the weight value of each load virtual server corresponding to the first load balance into the corresponding modified weight value.
The step is executed as follows: in the above example, after the preset cloud system receives the data items obtained by the load balancing weight processing system in step 103, the weight values of the relevant servers may be modified in batch in the following manner: aiming at first load balance, the weight value of the server a is modified to be 20%, the weight value of the server b is modified to be 30%, and the weight value of the server c is modified to be 50%; for load balancing, the weight value of the server a is modified to be 40%, the weight value of the server b is modified to be 20%, the weight value of the server d is modified to be 30%, and the weight value of the server e is modified to be 10%.

10%, the weight value of the server B after the modification is 60%; two modified weight values corresponding to load balancing inputs
Comprises the following steps: the modified weight value corresponding to the server A is 30%, and the modified weight value corresponding to the server B is 10%; thereby obtaining C
