Understand based on foregoing description, the technical scheme of the application, it is necessary first to definition extension point, this expansion
Machine plotting defines:
(1) extended mode (extending up or extension downwards), the application applied extend automatically
Time required calculating resource, extension time the instance number etc. adding or reduce.
Wherein it is possible to occur that the scene calculating inadequate resource is analyzed for application.Such as, currently
Application system during operation is at best able to carry the concurrent of 100 people, and when peak period, this application is also
The number of sending out may arrive the scale of 150 people, then estimate according to the calculating resource needed for current application system
Calculating resource required for application system when calculating peak, and define to corresponding extension point.With
Time, it is also possible to bind the virtual machine image template that this application system is corresponding, thus extend up at needs
Time, it is possible to it is quickly created virtual machine, to add example.
(2) extension point also define: the index of monitoring, including system index (as cpu load,
Memory usage etc.), application indexes (such as concurrent quantity, number of requests per second etc.).
Wherein it is desired to understand: this application is how to consume resource；Application disappears in high load situations
Consume any part resource；In high load situations, in order to maintain intended performance, potential for system
Extension point for can what happened etc..Then, based on above-mentioned understanding, in high load situations
Find the position of extension point, and increase more resource at these extension points, and observe the property of application
Energy.By the way, i.e. can determine that monitor control index clear and definite, effective.
Such as Web applies, the most typically application monitor control index includes:
1) concurrent user's quantity；
2) active connection quantity；
3) number of requests per second；
4) average delay time of each request.
(3) extension point also defines: the threshold values that every kind of index is corresponding.It is determined by the numerical value of index
Whether exceeding standard, if exceeding standard, then performing extended operation.
It is such as concurrent user's quantity of above-mentioned web application, active connection quantity, number of request per second
Amount, the average delay time etc. of each request, it is respectively provided with the threshold value of correspondence, to determine this index
The most normal.
As it is shown on figure 3, based on foregoing description, according to an embodiment of the invention cloud computing system is held
The idiographic flow of row application extension includes:
Step 302, application monitoring.I.e. the These parameters of application system is carried out real-time monitoring.Root
According to the threshold values set for These parameters, use any one or more monitor control index therein, adopt in real time
The sample that collection is corresponding, to determine whether to exceed standard.
Step 304, it is determined whether trigger extension point.Wherein, threshold value can be one, then more than or
During equal to this threshold value, determine and extend up, during less than this threshold value, determine extension downwards；Threshold value also may be used
Think two, then, when being more than or equal to bigger threshold value, determine and extend up, less than less threshold value
Time, determine extension downwards.
Meanwhile, directly judging except threshold value, it is also possible to periodically add up.Based on monitoring number
According to historical trend and actuarial prediction, it is possible to trigger extension point, be used for expanded application up or down
The number of example.
Ratio as shown in Figure 4, for certain monitor control index, arranges " extending up a little " and " expands downwards
Machine plotting " it is two corresponding threshold values.When this monitor control index is for the first time more than " extending up a little ",
Assuming that the time is t1, owing to t1 is less than the time threshold preset so that system can't perform extension
Operation；When monitor control index second time is more than " extending up a little ", it is assumed that the time is t2, due to t2
More than the time threshold preset so that system performs to extend up operation；When monitor control index less than " to
Lower extension point " time, it is assumed that the time is t3, owing to t3 is more than the time threshold preset so that system
Perform downward extended operation.
As it is shown on figure 3, when determine extend downwards time, i.e. enter step 306A: reduce example.When
Determine when extending up, i.e. enter step 306B: according to the calculating resource of application extension point definition,
Carry out calculating the application of resource, from mirror image management server, obtain the virtual machine image of correspondence, and create
Build virtual machine.After virtual machine creating completes, cloud computing system will carry out the extension behaviour applied automatically
Making, the mode using automatization is completed by whole expansion process.
Technical scheme being described in detail above in association with accompanying drawing, the present invention expands by introducing application
Machine plotting, defines the threshold values that monitor control index is corresponding, by the statistical analysis to monitoring data, triggers and expands
Machine plotting, reaches the dynamic expansion of application.Whole process need not manual intervention, and can active response answer
Run time behaviour.
Compare the extended mode of tradition application, need artificial application is monitored, and manual complete
The extension of application in pairs.Method provided herein achieves and automatically monitors application state, and being automatically performed should
Extension, meet the demand of applied business disposal ability, reduce business risk.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for
For those skilled in the art, the present invention can have various modifications and variations.All essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included in the present invention
Protection domain within.
