If the load balancing of each first server, then calculate the number of servers of dilatation according to every load value of each first server, and using the number of servers of dilatation as server expansion strategy.
The method that the embodiment of the present invention provides, when determining the load balancing of each first server, allows automatic dilatation, namely performs and determines server expansion strategy.Wherein, the automatic dilatation of server also can be arranged according to different traffic performances.
As a kind of embodiment, determine that whether the load of each first server is balanced, include but not limited to:
Calculate load mean value corresponding to every load value according to every load value of all first servers, and the load mean value that every load value is corresponding with every load value is compared;
If the difference of the load mean value that all load values are corresponding with every load value is all not more than default value, then determine the load balancing of each first server.
Wherein, the numerical value that default value can be different according to different business settings, the present embodiment does not limit the size of default value.Such as, default value can be 30% of load mean value.
In addition, the flow chart of load-balancing algorithm shown in Figure 4, determines that whether balanced the load of each first server process correspond to the load-balancing algorithm in Fig. 4.Wherein, the corresponding load mean value of average avg, avg is multiplied by business load fluctuation percentage f can obtain default value.When determining the load imbalance of arbitrary first server, not allowing the automatic dilatation carrying out server, namely terminating the dilatation of server.
For the ease of understanding, take first server as server 1, server 2 and server 3, loading index is A, B, C is that example is described.Wherein, the load value that server 1 corresponds to loading index A, B, C is respectively 1A, 1B and 1C, the load value that server 2 corresponds to loading index A, B, C is respectively 2A, 2B and 2C, the load value that server 3 corresponds to loading index A, B, C is respectively 3A, 3B and 3C, and default value is 30% of load mean value.Load mean value=(1A+2A+3A)/3 corresponding according to every load value computational load index A of all first servers, the load mean value that loading index B is corresponding=(1B+2B+3B)/3, the load mean value that loading index C is corresponding=(1C+2C+3C)/3, namely the load mean value that load value 1A, 2A and 3A is corresponding is (1A+2A+3A)/3, the load mean value that load value 1B, 2B and 3B are corresponding is (1B+2B+3B)/3, and the load mean value that load value 1C, 2C and 3C are corresponding is (1C+2C+3C)/3; Load value 1A, 2A and 3A are compared with load mean value (1A+2A+3A)/3 respectively, load value 1B, 2B and 3B are compared with load mean value (1B+2B+3B)/3 respectively, load value 1C, 2C and 3C are compared with load mean value (1C+2C+3C)/3 respectively; If the difference of load value 1A, 2A and 3A and load mean value (1A+2A+3A)/3 is not more than 30% of load mean value (1A+2A+3A)/3, and the difference of load value 1B, 2B and 3B and load mean value (1B+2B+3B)/3 is not more than 30% of load mean value (1B+2B+2B)/3, and the difference of load value 1C, 2C and 3C and load mean value (1C+2C+3C)/3 is not more than 30% of load mean value (1C+2C+3C)/3, then determine the load balancing of each first server.
In above-mentioned steps 203 when arbitrary load value of arbitrary first server is greater than load threshold corresponding to arbitrary load value, determine that this arbitrary load value is high capacity value; When the load balancing of each first server, can according to the number of servers of following formulae discovery dilatation:
Wherein, n represents the quantity of the server that there is high capacity value.
In addition, the relation of the relation of dilatation number of servers and idle server quantity, dilatation number of servers and runtime server quantity also may affect dilatation number of servers.Therefore, the quantity of dilatation server can be set according to the situation of reality.
Using the number of servers of dilatation after server expansion strategy, the second server of at least one dilatation and the running environment of second server can be configured according to server expansion strategy.
