In Dynamic Host Configuration Protocol server 34, can, in advance by MAC Address and the pairing of IP address, as long as the MAC Address of virtual machine instance is definite, just be defined as the IP address that its distributes like this;
Step 407: Virtual Machine Manager server 30 sends and adds instruction to load-balanced server 31, instruction load-balanced server 31 adds the IP address of the virtual machine instance newly creating in the list of load-balanced server 31 to.
The user of application system just can access the virtual machine instance of new establishment like this, and load-balanced server 31 can arrange certain distribution policy, the new user of application system is pointed to the virtual machine instance of new establishment.
Step 408: Virtual Machine Manager server 30 is determined the virtual machine instance that will close;
The general minimum virtual machine instance of number of users of selecting of Virtual Machine Manager server 30 is as the virtual machine instance that will close, because just this virtual machine instance can be closed after will waiting until the complete off-line of these users or they being switched to other virtual machine instance;
Step 409: Virtual Machine Manager server 30 sends the first out code to load-balanced server 31, the virtual machine instance that instruction will be closed;
Step 410: load-balanced server 31 no longer points to by new user the virtual machine instance that will close, and the user of the virtual machine instance that will close is switched to other virtual machine instance;
Load-balanced server 31 can be deleted the IP address of this virtual machine instance from list, and user will not visit again this virtual machine instance like this;
Step 411: in the time that the number of users of this virtual machine instance of access reduces to 0 gradually, load-balanced server 31 notifies Virtual Machine Manager server 30 these virtual machine instance to close;
Load-balanced server 31 is deleted this virtual machine instance from application, and notifies Virtual Machine Manager server 30 these virtual machine instance to close;
Step 412: Virtual Machine Manager server 30 sends the second out code to Virtual Machine Manager client 33 corresponding to this virtual machine instance, instruction Virtual Machine Manager client 33 is closed this virtual machine instance.
So just can discharge in time the physical resource that this virtual machine instance takies, improve the utilization factor of physical machine
In the present embodiment, Virtual Machine Manager server is every the online user number of an application system of predetermined time interval acquiring, and according to the automatic virtual machine instance that increases or reduce application system of the online user number of application system, the present embodiment can be adjusted automatically according to application system load the quantity of virtual machine instance, response user's request fast, the utilization factor of raising physical machine.
