This application provides a kind of disaster tolerance system, Fig. 1 is a kind of disaster tolerance system shown according to an exemplary embodiment
Structural schematic diagram, as shown in Figure 1, the system includes disaster tolerance control centre 01 and multiple application examples 02, the application be can use
Virtual machine (Virtual Machine, VM) carries application example and disaster tolerance control centre, carries the VM of each application example
Can be different, the VM and the VM of carrying disaster tolerance control centre for carrying application example can be different.Disaster tolerance control centre can with answer
With data interaction is carried out between example, for example, disaster tolerance control centre can send to application example carries junior in disaster tolerance website
The switching notice of the address of disaster tolerance application, so that application example is according to junior's disaster tolerance application in the call by location disaster tolerance website.
Present invention also provides a kind of disaster recovery method, Fig. 2 is a kind of disaster recovery method shown according to an exemplary embodiment
Flow chart, as shown in Fig. 2, this method be applied to disaster tolerance control centre 01 shown in FIG. 1 in.There is failure in production website
Junior application, and the failure junior application have corresponding disaster tolerance application in disaster tolerance website.Junior application
Higher level's application needs that junior application is called to carry out finishing service request.For the application example of the higher level application in production website
Disaster tolerance switching is completed, when processing service requests, junior application of the meeting into disaster tolerance website is called, finishing service
Request.But producing new online higher level's application example in website can still call in production website due to being not carried out disaster tolerance notice
Failed junior's application, therefore it is unable to complete service request.
This approach includes the following steps.
In step s101, disaster tolerance control centre, which determines, has new online higher level's application example in production website;
In this application, when needing a new online application example in producing website, the platform produced in website is
Service (Platform as a Service, PaaS) layer can be used virtual machine image and create VM in production website, and new
An application example is disposed on the VM of creation, then starts the application example of deployment, to realize new online in production website
One application example.
When needing an offline application example in producing website, PaaS layers can unload the offline application of needs in fact
Example, to realize an offline application example in production website;Further, it can also unload for carrying offline application
The VM of example.
Disaster tolerance control centre has subscribed PaaS layers topology (TOPO) information change notifying in production website, whenever producing
In website when new online higher level's application example, PaaS layers can send TOPO information change notifying to disaster tolerance control centre,
There is new online higher level's application example in TOPO information change notifying instruction production website.Each application example can be periodically to appearance
Calamity control centre sends heartbeat message, and when higher level's application example offline in producing website, disaster tolerance control centre is not
The heartbeat message of offline higher level's application example can be received again, therefore disaster tolerance control centre can determine higher level's application example
It is offline.
In step s 102, disaster tolerance control centre obtains disaster tolerance operation object belonging to new online higher level's application example;
In this application, application example can be classified in advance, for example, according to its function classification.Such as calculate the application of class
Example, the application example of image processing class and the application example for obtaining web data class etc..
For example, being illustrated by taking the application example for calculating class as an example, online calculating class is answered in production website
Calculating service can be externally provided with example, for example, processing computation requests, required junior is answered when handling computation requests
It is produced in website with being stored in.
When user, which needs to produce website, to be calculated some data, user can send to calculate to production website and ask
It asks, calculative data is carried in computation requests, production website receives the computation requests, and the computation requests are distributed to
The application example of calculating class online in website is produced, the application example for calculating class receives the computation requests, from the computation requests
In extract calculative data, and call junior to apply from production website and calculative data calculated, thus complete
The processing of the pairs of computation requests.
For example, production website provides the service for calculating Individual Income Tax, user can be submitted to production website for calculating
The computation requests of Individual Income Tax, the computation requests carry the pre-tax salary of user, pay the amount of money of social security and pay public product
The amount of money of gold, the required junior's application used can provide the calculating public affairs for calculating Individual Income Tax when calculating Individual Income Tax
The computation requests can be distributed to the application for calculating class when production website receives the computation requests of user's submission by formula
Example can be mentioned when the application example for calculating class gets the computation requests of production website distribution from the computation requests
The pre-tax salary of user is taken out, the amount of money of social security is paid and pays the amount of money of common reserve fund, and calling from production website should
Junior's application of calculation formula is provided, to the pre-tax salary of user, pay the amount of money of social security and pay the amount of money of common reserve fund into
The Individual Income Tax of user is calculated in row.
However, production website often receives a large amount of computation requests in a short time as portfolio is gradually increased,
Such as needing to calculate respective Individual Income Tax in a large amount of user's short time, the application example for calculating class due to one is primary only
A computation requests are capable of handling, in order to improve the efficiency for handling these computation requests, are produced often online multiple in website
The application example of class is calculated, multiple application examples for calculating class belong to same type of application example.Same type of application is real
Example needs to produce the junior's application called in website can be identical, for example, it is desired to which the junior's application called is to calculate personal institute
Obtain junior's application etc. of tax.
Therefore, when need by the junior of a certain higher level's application example using call address from production website switch to disaster tolerance station
When point, generally require the junior for belonging to same type of all application examples with higher level's application example is equal using call address
Disaster tolerance website is switched to from production website.
Correspondingly, in this application, (hold as sent when needing to execute disaster tolerance handover operation to a certain higher level's application example
Calamity switching notice), generally require to the application example belong to same type of all application examples be performed both by disaster tolerance switching grasp
Make.
In order to facilitate handover operation is executed, in this application, can by production website it is online belong to it is same type of
Application example forms a disaster tolerance operation object, and the instance identification for belonging to same type of application example is formed application example
Identification list.
In this application, VM is created in production website using virtual machine image when PaaS layers, and on newly created VM
It disposes after an application example and the application example of starting deployment, PaaS layers also need to create the application example in VM
Configuration information, and store in the configuration information of the application example object mark of disaster tolerance operation object belonging to the application example
Know.In this way, later when determining that needing to be implemented disaster tolerance switches, the disaster tolerance operation object according to belonging to the application example
Object identity is determined to belong to same type of all application examples, and executes appearance to same type of all application examples are belonged to
Calamity handover operation.
Therefore, in this step, the configuration information of the available new online higher level's application example of disaster tolerance control centre, should
Configuration information includes the object identity of disaster tolerance operation object belonging to new online higher level's application example, and confidence should be matched by then obtaining
Object identity in breath, and disaster tolerance operation object corresponding to the object identity is determined as new online higher level's application example institute
The disaster tolerance operation object of category.
In this application, it is also possible to which there is no disaster tolerance operation objects belonging to new online higher level's application example, if not
In the presence of disaster tolerance operation object belonging to new online higher level's application example, it is determined that new online higher level's application example is not related to holding
Calamity demand, so as to terminate process.
In step s 103, the instance identification of new online higher level's application example is stored in disaster tolerance behaviour by disaster tolerance control centre
Make in the application example identification list of object;
In step S104, disaster tolerance control centre obtains application example identity column when determining that needing to be implemented disaster tolerance switches
The instance identification of new online higher level's application example in table;
In this application, when normal service can not be provided by producing junior's application in website, disaster tolerance control centre is determined
Need to be implemented disaster tolerance switching.
Such as, it is generally the case that when higher level's application example calls junior's application to complete a service request in production website
Later, junior's application can return to a feedback information, and feedback information is to indicate that the service request has been handled.However, working as
After junior's application is broken down, new online higher level's application may can not call junior application to complete to service request
Processing, junior's application can not Normal Feedback information, such as return to error message or not return information, and then can determine in production website
Junior application is broken down, thus may determine that needing to be implemented disaster tolerance switching.
Alternatively, disaster tolerance control centre, which determines, to need to hold when disaster tolerance control centre receives the switching request of user's submission
The switching of row disaster tolerance.For example, user can determine the need for executing disaster tolerance switching according to actual needs, when needing to be implemented disaster tolerance
When switching, switching request can be submitted to disaster tolerance control centre, after disaster tolerance control centre receives the switching request, determined
Need to be implemented disaster tolerance switching.
There is also the scene that other need to be implemented disaster tolerance switching, herein a different citings in the application.
In step s105, disaster tolerance control centre is according to the instance identification of new online higher level's application example to new online
Higher level's application example sends disaster tolerance switching notice, and the new online higher level's application example of instruction calls the junior to apply in disaster tolerance website
In corresponding disaster tolerance application, disaster tolerance switching notice at least carries the address that the disaster tolerance in disaster tolerance website is applied.
In step s 106, new online higher level's application example receives the disaster tolerance switching notice that disaster tolerance control centre sends;
In step s 107, new online higher level's application example applies the corresponding disaster tolerance in disaster tolerance website to answer according to junior
Address executes disaster tolerance handover operation.
After new online higher level's application example receives disaster tolerance switching notice, no longer the junior is applied from production website
It is called, but the junior is called using corresponding disaster tolerance application from disaster tolerance website, complete to service request
Processing.
Further, in the another embodiment of the application, disaster tolerance control centre can also apply to new online higher level
Other higher level's application examples that example belongs to same disaster tolerance operation object send disaster tolerance switching notice, so that with new online higher level
Other higher level's application examples that application example belongs to same disaster tolerance operation object execute disaster tolerance according to the disaster tolerance switching notice respectively
Handover operation.
In this application, disaster tolerance control centre, which determines, has new online higher level's application example in production website;Disaster tolerance control
Center processed obtains disaster tolerance operation object belonging to new online higher level's application example;New online higher level answers in disaster tolerance control centre
It is stored in the application example identification list of disaster tolerance operation object with the instance identification of example;Disaster tolerance control centre is determining needs
When executing disaster tolerance switching, the instance identification of new online higher level's application example in application example identification list is obtained;Disaster tolerance control
Center processed sends disaster tolerance switching to new online higher level's application example according to the instance identification of new online higher level's application example and leads to
Know, the new online higher level's application example of instruction calls the junior to apply the corresponding disaster tolerance application in disaster tolerance website, disaster tolerance switching
Notice at least carries the address of disaster tolerance application in disaster tolerance website.New online higher level's application example receives disaster tolerance control centre hair
The disaster tolerance switching notice sent;New online higher level's application example applies the corresponding disaster tolerance application in disaster tolerance website according to junior
Address execute disaster tolerance handover operation.So that new online higher level's application example can be just after breaking down for production stations point
True processing business request.
In this application, the quantity for the service request that production website receives in section in different times may be different,
When the quantity of the service request received gradually increases, in order to improve the efficiency of processing business request, need in production website
In new online application example, in order to save system resource, needed in life when the quantity of the service request received gradually decreases
Produce offline certain applications example in website.
After offline some application examples in producing website, it is assumed that production stations point breaks down, if disaster tolerance operates
There is also the instance identifications of offline application example in the application example identification list of object, then are sending disaster tolerance switching notice
When, disaster tolerance control centre, which can also send according to the application example identification list of disaster tolerance operation object to offline application example, to be held
Calamity switching notice, but in fact, be not necessarily to send disaster tolerance switching notice to offline application example at this time, to offline
Application example send disaster tolerance switching notice can waste system resource.
Therefore, in order to save system resource, disaster tolerance control centre need to only send to currently not offline application example to be switched
Notice, without sending switching notice to offline application example again.
In order to no longer send switching notice to offline application example, in this application, disaster tolerance control centre also needs
Determining in production website whether there is offline application example, if there is offline application example in production website,
Disaster tolerance control centre is then it needs to be determined that disaster tolerance operation object belonging to offline application example, and in offline application example
The instance identification of offline application example is deleted in the application example identification list of affiliated disaster tolerance operation object.In S101
It has been be illustrated that, after producing an offline application example in website, disaster tolerance control centre will not receive the application example again
Heartbeat message, therefore can determine that the application example is offline, disaster tolerance of the instance identification of the application example belonging to it grasped
Make to delete in the application example identification list of object.
In this way, later when sending disaster tolerance switching notice, the disaster tolerance operation object as belonging to offline application example
Application example identification list in the instance identification of offline application example, therefore, disaster tolerance control centre root has been not present
It would not be again to offline application according to the application example identification list of disaster tolerance operation object belonging to offline application example
Example sends disaster tolerance switching notice, so as to save system resource.
In this application, application example online in production website periodically can send heartbeat letter to disaster tolerance control centre
Breath, after disaster tolerance control centre receives the heartbeat message that a certain application example is sent, so that it may determine that the application example is
Online application example.Wherein, if not receiving a certain application example in preset duration sends heartbeat message, it is determined that this is answered
It is offline with example.
In this application, multiple application examples without type may be carried in a VM simultaneously, it is different types of to answer
May be different with the communication interface of example, disaster tolerance control centre needs while supporting the communication interface of each application example,
It so could and be interacted between each application example online in production website, but will increase disaster tolerance control in this way
The system complexity at center and the close coupling between application example.
In this application, on a kind of basis of disaster tolerance system shown in Fig. 1, with reference to Fig. 3, present invention also provides another
A kind of disaster tolerance system, Fig. 3 are a kind of structural schematic diagrams of disaster tolerance system shown according to an exemplary embodiment, as shown in figure 4,
The system includes that disaster tolerance control centre 01, multiple application examples 02 and multiple Disaster Recovery Agent further include within the system multiple
VM, one of VM carry disaster tolerance control centre, carry one or more application in each of other VM VM
Example, each carrying application example VM in be also deployed with Disaster Recovery Agent.Disaster tolerance control centre can be between Disaster Recovery Agent
It interacts, for example, disaster tolerance control centre can send disaster tolerance switching notice to Disaster Recovery Agent, so that Disaster Recovery Agent is according to the appearance
The corresponding application example of calamity switching notice executes disaster tolerance handover operation.
In this application, disaster tolerance control centre only needs to interact between Disaster Recovery Agent, without real with each application
Example interacts respectively, for example, disaster tolerance control centre sends disaster tolerance switching notice to Disaster Recovery Agent, Disaster Recovery Agent receives the disaster tolerance
Switching notice, and the address pair that corresponding disaster tolerance is applied in disaster tolerance website is applied according to the junior that the disaster tolerance switching notice carries
