In some embodiments of the present invention, a resource refers to a computing resource, a storage resource, a network resource, and the like inside a cloud resource pool, such as a CPU resource, a vCPU resource, a disk resource, a memory resource, and the like.
Resource requirements refer to the allocation requirements or change requirements of users to these resources. For example, a user needs 10 virtual machines allocated to a cloud resource pool, and each virtual machine allocates 4 vcpus, 8G memories, 2T storage spaces, and the like; or the user needs to add 10 virtual machines due to the increase of the traffic, and the like.
Fig. 1B is a block diagram of a data disaster recovery system according to some embodiments of the present invention. As shown in fig. 1B, the data disaster recovery system 10 of this embodiment includes a policy arbitration device 101, and cloud management platforms 102, 103, and 104.
In some embodiments, a cloud resource pool may also be included in the system, and the cloud management platforms 102, 103, and 104 may take over the cloud resource pools 1021 and 1022, 1031 and 1032, 1041, and 1042, respectively. An adaptation layer may be disposed between the cloud management platform and the cloud resource pool, and the adaptation layer and the cloud management platform may be connected and communicate through an Application Programming Interface (API).
More cloud management platforms and cloud resource pools can be arranged in the system as required, and fig. 1 does not play any limiting role on the number of the cloud management platforms and the cloud resource pools.
In the system according to some embodiments of the present invention, both the policy arbitration device and the cloud management platform store all resource information in the system, that is, the resource topology in the system. Therefore, when a certain cloud management platform fails, other cloud management platforms can take over quickly.
When the resource requirement is issued to the home cloud management platform, it is also issued to the policy arbitration device 101 for backup. After the home cloud management platform changes resources according to resource requirements, the policy arbitration device updates the resource information in time to keep the latest and most accurate resource information, and instructs other cloud management platforms to update the resource information. The data replication process adopts an asynchronous replication mode.
A data disaster recovery method according to an embodiment of the present invention is described below with reference to fig. 2.
Fig. 2 is a flow diagram of a data disaster recovery method according to some embodiments of the invention. As shown in fig. 2, the data disaster recovery method of the embodiment includes: steps S202 to S208.
In step S202, the policy arbitration device receives a resource requirement, where the resource requirement is further issued to the home cloud management platform, so that the home cloud management platform performs resource change according to the resource requirement.
The home cloud management platform is a cloud management platform for directly providing cloud services for users, that is, a cloud management platform for directly receiving and processing resource requirements of one or more users. Thus, the home cloud management platform may be a relative concept, that is, a certain cloud management platform may be the home cloud management platform of the user a, but may not be the home cloud management platform of the user B; the same user may also correspond to one or more home cloud management platforms, as desired.
In step S204, the policy arbitration device receives a resource change message asynchronously copied by the home cloud management platform, where the resource change message is generated by the home cloud management platform by changing resources according to the resource requirement.
When the home cloud management platform changes resources according to resource requirements, resource information in the system, namely information such as resource topology and resource description, is changed. In addition to the home cloud management platform knowing the change, the home cloud management platform also informs the policy arbitration device of the resource change information, so that the policy arbitration device can update the resource information change condition in the system in time.
In some embodiments, the home cloud management platform may copy the resource change Message to the policy arbitration device using AMQP (Advanced Message Queuing Protocol).
In step S206, the policy arbitration device changes the resource information according to the resource change message.
In step S208, the policy arbitration device asynchronously copies the resource change message to another cloud management platform, so that the other cloud management platform changes the resource information according to the resource change message.
The other cloud management platforms may be all the cloud management platforms in the system except the home cloud management platform, or may be a backup cloud management platform that is pre-designated for a certain home cloud management platform.
In some embodiments, the other cloud management platforms may feed back a response of successful replication to the policy arbitration device after successful replication, and the policy arbitration device deletes the resource requirement after receiving the response of successful replication, so as to prevent some cloud management platforms from being unsuccessfully replicated. The policy arbitration means may send the resource requirement again in response to a request of the other cloud management platform.
Those skilled in the art may also choose not to delete the resource requirement stored in the policy arbitration module, or adopt a mode of periodic deletion, etc., which will not be described herein again.
By the method of the embodiment, the policy arbitration device can respond to the new resource requirement received in the system to update the resource information of the system in time, and synchronously asynchronously copy the change to other cloud management platforms in the system, so that the other cloud management platforms can update the resource information of the system in time, and therefore when the home cloud management platform fails, the other cloud management platforms can take over quickly, quick service switching under the failure condition is realized, and the switching efficiency and the success rate are both improved.
When the home cloud management platform has abnormal conditions such as failure, loss of connection and disconnection, or the home cloud management platform needs to be updated, expanded and the like, or the home cloud management platform cannot continue to work in response to a specific instruction, the policy arbitration device may instruct other cloud management platforms to take over the home cloud management platform. The cloud management platform can take over one or more than one cloud management platform.
The policy arbitration module can schedule other cloud management platforms to take over in various ways such as random take-over, average division take-over, policy distribution take-over, active take-over, fixed sequence take-over, load balancing take-over and the like. The random takeover refers to a cloud management platform which is randomly appointed to take over; the average division of takeover refers to that the administration resources of the taken over cloud management platform are averagely distributed to the cloud management platforms of a plurality of takeover; the policy allocation takeover means that each resource pool governed by the cloud management platform to be taken over is allocated to a different cloud management platform for taking over; the active takeover means that the taken over cloud management platform has no fault, but a takeover strategy during operation such as upgrading and capacity expansion; the fixed sequence takeover refers to that other cloud management platforms are appointed to take over according to a certain sequence; the load balancing takeover refers to selecting a cloud management platform which is idle at present to take over.
Two takeover methods and the corresponding operations after takeover are exemplarily described below.
First, a processing method when a home cloud management platform fails in a resource demand issuing process is described with reference to fig. 3.
Fig. 3 is a flowchart of a data disaster recovery method according to further embodiments of the present invention. As shown in fig. 3, the data disaster recovery method of this embodiment includes steps S302 to S308.
In step S302, the policy arbitration device and the home cloud management platform receive a resource requirement.
In step S304, the policy arbitration module does not receive the resource change message sent by the home cloud management platform, and instructs other cloud management platforms to take over the home cloud management platform.
For example, the wait time of the policy arbitration module may be preset. When the policy arbitration device does not receive the resource change message sent by the home cloud management platform within the waiting time, the policy arbitration device may instruct other cloud management platforms to take over the home cloud management platform.
In step S306, the policy arbitration device actively forwards the resource requirement to the cloud management platform taking over.
In step S308, the cloud management platform taking over performs resource change according to the resource requirement.
Similar to the normal process flow, the method of this embodiment may further include: the method comprises the steps that a policy arbitration device receives a resource change message which is taken over and asynchronously copied by a cloud management platform, and changes resource information according to the resource change message; and then, the strategy arbitration device asynchronously copies the resource change message to other cloud management platforms except the takeover cloud management platform, so that the other cloud management platforms change the resource information according to the resource change message.
By the method of the embodiment, in the resource requirement issuing process, the policy arbitration device can instruct other cloud management platforms to take over under the condition that the attribution cloud management platform does not respond, and forward the resource requirement consistent with the resource requirement obtained by the attribution cloud management platform to the cloud management platform taking over for resource change, so that service switching can be rapidly realized.
The strategy arbitration module can passively acquire the abnormal condition of the cloud management platform and can actively monitor the cloud management platform. The policy arbitration device may instruct other cloud management platforms to take over the home cloud management platform in response to monitoring that the home cloud management platform is abnormal. In one embodiment, the policy arbitration module may be connected to each cloud management platform through a heartbeat line, so that abnormal conditions of cloud management can be monitored in time. The following describes a processing method when the policy arbitration module monitors that the home cloud management platform has a fault, with reference to fig. 4.
Fig. 4 is a flowchart of a data disaster recovery method according to other embodiments of the present invention. As shown in fig. 4, the data disaster recovery method of this embodiment includes steps S402 to S408.
In step S402, the policy arbitration device instructs other cloud management platforms to take over the home cloud management platform in response to monitoring that the home cloud management platform is abnormal.
In step S404, the cloud management platform taking over receives an operation on the abnormal resource by the user.
In the process of asynchronous replication, there may be a replication error, a replication interruption, and the like, which may cause that the cloud management platform that is taken over may not have the latest resource information, so that when a user operates a resource that the cloud management platform that is taken over does not have, that is, an abnormal resource, an operation failure may occur.
In step S406, the cloud management platform that takes over sends an inquiry request to the policy arbitration device in response to that the resource corresponding to the user operation cannot be inquired.
In step S408, the policy arbitration device copies the data saved by the policy arbitration device to the cloud management platform taking over.
If the policy arbitration device still stores the resource requirement corresponding to the abnormal resource, the resource requirement can be sent to the takeover cloud management platform, so that the takeover cloud management platform can change the resource. Or the policy arbitration device may also send the resource information related to the abnormal resource to the cloud management platform taking over. Therefore, the strategy arbitration device can carry out data consistency check and ensure the operation requirements of users.
By the method of the embodiment, the policy arbitration device can actively monitor the abnormal condition of the home cloud management platform, and quickly check the data consistency when the taken-over cloud management platform cannot find the resource requirement corresponding to the user operation, so that the stability of the cloud service and the user experience are improved.
