Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the embodiment of the invention, the technical problem that user data is lost because user data written into public cloud storage cannot be accessed during gray scale is solved if the public cloud storage middleware is unstable or even fails and services are switched back to the private cloud, and the user data on the public cloud is stored into the private cloud during gray scale.
However, since a plurality of storage middleware, for example MySQL, mongoDB, redis, couchbase, are involved, bidirectional synchronization cannot be achieved depending on the own functions of the storage middleware, and therefore, the bidirectional synchronization can be achieved only by a program. Two schemes exist for realizing data synchronization through programs, and the method is simple and direct in storage double-writing in public cloud service, and has the defects of too much dependence and too long operation flow, so that interface time consumption is increased, and interface stability is also influenced. The second scheme is that asynchronous messages are sent out by public cloud service, and individual consumers are deployed by private cloud, so that the messages are consumed, and data are written into the private cloud for storage. The method is complex, but can realize double writing of data without affecting normal on-line service, so that the second scheme is selected.
Based on the above-mentioned inventive concept, as shown in fig. 1, a schematic implementation flow diagram of a hybrid cloud data synchronization method provided by an embodiment of the present invention is applied to public clouds, and the method specifically may include the following steps:
s101, determining a switch state field corresponding to a target service, wherein the target service is a service which is migrated from a private cloud to a public cloud for deployment.
In the embodiment of the invention, for a certain service, the service needs to be migrated from a private cloud to a public cloud for deployment. In order to control the whole process of transferring from private cloud to public cloud for deployment, for service, relevant switch state fields are designed, corresponding switch state field values are different, and corresponding processes are different.
Based on the switch state field, the switch state field corresponding to the target service is determined, wherein the target service is a service which is migrated from the private cloud to the public cloud for deployment. For example, a switch state field corresponding to the service a is determined, and the switch state field is stored in a cloud platform configuration center, wherein the service a is a service that is deployed by migrating from a private cloud to a public cloud.
S102, acquiring a switch state field value corresponding to the switch state field, and judging whether the switch state field value meets the preset requirement.
In the embodiment of the invention, the switch state field is stored in the cloud platform configuration center, so that the switch state field value corresponding to the switch state field can be obtained from the cloud platform configuration center. Wherein the relationship of the switch state field to the switch state field Value is similar to the relationship of Key-Value.
It should be noted that, for the switch state field value, the switch state field value is 0, which is determined by the state that the target service is migrated from the private cloud to the public cloud for deployment, for example, the state before gray scale deployment, the formally online completion, the data back cut, etc., which is not limited in the embodiment of the present invention.
In addition, for the switch state field value corresponding to the switch state field, whether the switch state field value meets the preset requirement needs to be judged, so that whether the synchronization message of the public cloud incremental data to the private cloud is triggered is determined according to the judging result.
It should be noted that, for the switch state field value corresponding to the switch state field, whether the switch state field value meets the preset requirement is determined, which is essentially whether the switch state field value is a certain preset value, which is not limited in the embodiment of the present invention.
And S103, triggering a synchronization message for synchronizing the public cloud incremental data to the private cloud under the condition that the switch state field value meets the preset requirement.
In the embodiment of the invention, for the switch state field value, whether the switch state field value meets the preset requirement is judged, and the synchronous message is sent and consumed at the same time under the condition that the switch state field value meets the preset requirement, so that the synchronous message of the public cloud incremental data to the private cloud can be triggered.
It should be noted that, for the synchronization message, the public cloud incremental data (for example, user incremental data) is corresponding to the public cloud incremental data, and the public cloud incremental data needs to be calculated in real time, which is not limited by the embodiment of the present invention.
S104, sending the synchronous message to the message cluster, notifying the private cloud consumer to consume the synchronous message in the message cluster, and synchronizing the incremental data in the public cloud to the private cloud.
In the embodiment of the invention, the synchronous message is sent to the message cluster, and the private cloud consumer is informed to consume the synchronous message in the message cluster, so that the incremental data in the public cloud can be synchronized to the private cloud, the bidirectional synchronization of the data between the private cloud and the public cloud can be realized, and the consistency of the data is ensured.
It should be noted that, when the private cloud sets up the consumer of the synchronization message in advance, the public cloud sends the synchronization message to the message cluster, and then the public cloud sends a notification, after the private cloud consumer receives the notification, the private cloud consumes the synchronization message in the message cluster, and synchronizes the incremental data in the public cloud to the private cloud.
Through the description of the technical scheme provided by the embodiment of the invention, the switch state field corresponding to the target service is determined, the switch state field value corresponding to the switch state field is obtained, and under the condition that the switch state field value meets the preset requirement, the synchronization message of the public cloud incremental data to the private cloud is triggered, the synchronization message is sent to the message cluster, and the private cloud consumer is informed to consume the synchronization message in the message cluster, so that the public cloud incremental data is synchronized to the private cloud.
Therefore, bidirectional synchronization of data between the private cloud and the public cloud can be realized, consistency of the data is guaranteed, if unstable conditions or even faults occur in the storage middleware of the public cloud, services are switched back to the private cloud, user data written into the public cloud storage during gray scale can still be accessed, and user data loss is avoided.
As shown in fig. 2, a schematic implementation flow chart of another hybrid cloud data synchronization method provided by the embodiment of the present invention is applied to public clouds, and may specifically include the following steps:
s201, determining a switch state field corresponding to a target service, wherein the target service is a service which is migrated from a private cloud to a public cloud for deployment.
In the embodiment of the present invention, the step is similar to the step S101, and the embodiment of the present invention is not described here again.
S202, a switch state field value corresponding to the switch state field is obtained, whether the switch state field value is a preset first value is judged, and the preset first value represents that the synchronous message is not sent and is not consumed.
S203, acquiring a state corresponding to the target service under the condition that the switch state field value is a preset first value.
S204, according to the state corresponding to the target service, the incremental data are stored to the public cloud or the private cloud.
In the embodiment of the invention, for the switch state field, the switch state field is stored in the cloud platform configuration center, so that the switch state field value corresponding to the switch state field can be obtained from the cloud platform configuration center, and whether the switch state field value is a preset first value is judged, wherein the preset first value characterizes that the synchronization message is not sent and is not consumed, which means that the public cloud to private cloud data synchronization is not performed at the moment.
Under the condition that the switch state field value is a preset first value, acquiring a state corresponding to the target service, and storing the incremental data to the public cloud or the private cloud according to the state corresponding to the target service, wherein the state corresponding to the target service determines to store the incremental data to the public cloud or the private cloud.
For example, a switch state field value corresponding to the switch state field is obtained from the cloud platform configuration center, and whether the switch state field value is 0 is determined, wherein the switch state field value is equal to 0, which means that no synchronization message is sent and no synchronization message is consumed, meaning that no public cloud to private cloud data synchronization is performed at this time.
And under the condition that the switch state field value is 0, acquiring a state corresponding to the target service, wherein the state is a state before gray level deployment, when formally online completion or data back-cut, and accordingly storing the incremental data to the public cloud or the private cloud according to the state corresponding to the target service, wherein the state of the target service is a state before gray level deployment or when data back-cut, the incremental data is required to be stored to the private cloud, and the state of the target service is a state after formally online completion, and the incremental data is required to be stored to the public cloud.
It should be noted that, for the state corresponding to the target service, the state is a state before gray level deployment, when the formally online is completed or the data is switched back, so that the switch state field value can be set to a preset first value, for example, the preset first value is set to 0, so that the data synchronization from public cloud to private cloud is not performed afterwards.
S205, judging whether the switch state field value is a preset second value, wherein the preset second value represents that the synchronous message is sent and the synchronous message is not consumed.
S206, triggering the synchronization message of the public cloud incremental data to the private cloud under the condition that the switch state field value is a preset second value, and sending the synchronization message to the message cluster.
In the embodiment of the invention, for the switch state field value corresponding to the switch state field, whether the switch state field value is a preset second value can be judged, the preset second value represents that the synchronous message is sent and the synchronous message is not consumed, and under the condition that the switch state field value is the preset second value, the synchronous message of the public cloud incremental data to the private cloud is triggered and the synchronous message is sent to the message cluster.
For example, for a switch state field value corresponding to the switch state field, determining whether the switch state field value is 1, where a switch state field value equal to 1 represents sending a synchronization message but not consuming the synchronization message, triggering synchronization of public cloud incremental data to a synchronization message of a private cloud and sending the synchronization message to a message cluster under the condition that the switch state field value is 1.
In addition, when the switch status field value is a preset second value (for example, 1), the status of the target service is in the state of gray scale deployment, and unidirectional data synchronization from the private cloud to the public cloud is performed. Because the private cloud is stored to the public cloud to store the unidirectional data synchronization at the moment, the message synchronization message cannot be started, and the message synchronization message is stored only in the message cluster, otherwise, the public cloud data is repeatedly written.
For example, the user completes the check-in action, the API service stores a check-in record to the public cloud, then triggers the public cloud delta data to synchronize to the synchronization message of the private cloud, and sends the synchronization message to the message cluster. If the value of the switch state field corresponding to the switch state field is 2, the private cloud consumer can consume the synchronous message and store a check-in record to the private cloud, and if the unidirectional data stored by the private cloud to the public cloud is not synchronous, the check-in record can be synchronized to the public cloud, two check-in records of the user can exist in the public cloud, and data is rewritten.
In addition, it should be noted that, for the state corresponding to the target service, the state is a state in gray scale deployment, so that the switch state field value may be set to a preset second value (for example, 1), and the synchronization message may be sent later but not consumed.
S207, judging whether the switch state field value is a preset third value, wherein the preset third value represents sending and consuming the synchronous message.
And S208, triggering a synchronization message for synchronizing the public cloud incremental data to the private cloud under the condition that the switch state field value is a preset third value.
S209, sending the synchronous message to the message cluster, notifying the private cloud consumer to consume the synchronous message in the message cluster, and synchronizing the incremental data in the public cloud to the private cloud.
In the embodiment of the invention, for the switch state field value corresponding to the switch state field, whether the switch state field value is a preset third value can be judged, the preset third value represents that the synchronous message is sent and the synchronous message is consumed, and under the condition that the switch state field value is the preset third value, the synchronous message of the public cloud incremental data to the private cloud is triggered, the synchronous message is sent to the message cluster, and the private cloud consumer is informed of consuming the synchronous message in the message cluster, and the incremental data in the public cloud is synchronized to the private cloud.
For example, for the switch state field value corresponding to the switch state field, it may also be determined whether the switch state field value is 2, where the switch state field value is equal to 2, and represents that a synchronization message is sent and a synchronization message is consumed, and when the switch state field value is 2, a synchronization message for synchronizing public cloud incremental data to a private cloud is triggered, the synchronization message is sent to a message cluster, and a private cloud consumer is notified to consume the synchronization message in the message cluster, and incremental data in the public cloud is synchronized to the private cloud.
It should be noted that, for the state corresponding to the target service, the state is a state in which the gray deployment is completed, and thus the switch state field value may be set to a preset third value, for example, the preset third value is 2, so that the synchronization message may be sent and consumed later.
Furthermore, in the embodiment of the present invention, during the period of sending and consuming the synchronization message, it is necessary to ensure that unidirectional data synchronization from the private cloud to the public cloud has been interrupted. And when the one-way data synchronization from the private cloud to the public cloud is not interrupted, interrupting the one-way data synchronization from the private cloud to the public cloud and triggering the synchronization message of the public cloud incremental data synchronization to the private cloud.
For example, if the switch state field value is 2, detecting whether unidirectional data synchronization from the private cloud to the public cloud is interrupted, if unidirectional data synchronization from the private cloud to the public cloud is interrupted, triggering a synchronization message for synchronizing the public cloud incremental data to the private cloud, sending the synchronization message to the message cluster, notifying a private cloud consumer to consume the synchronization message in the message cluster, and synchronizing the public cloud incremental data to the private cloud.
Under the condition that unidirectional data synchronization from private cloud to public cloud is not interrupted, interrupting unidirectional data synchronization from private cloud to public cloud by DBA, triggering synchronous message of public cloud incremental data synchronization to private cloud, sending synchronous message to message cluster, notifying private cloud consumer to consume synchronous message in message cluster, and synchronizing incremental data in public cloud to private cloud.
In addition, for the synchronous message, there is a corresponding trigger time, so that the private cloud consumer can follow the trigger time of the synchronous message in the process of consuming the synchronous message, and the following principle can be priority triggering and priority consumption. Therefore, in the embodiment of the invention, the public cloud can inform the private cloud consumer to consume the synchronous message in the message cluster according to the triggering time of the synchronous message, and synchronize the increment data in the public cloud to the private cloud.
It should be noted that, for the steps S202 to S204, S205 to S206, and S207 to S209, that is, the processing steps of whether the switch status field value is the preset first value, the preset second value, or the preset third value, the execution sequence may be, for example, executing S202 to S204, then executing S205 to S206, and finally executing S207 to S209.
Through the description of the technical scheme provided by the embodiment of the invention, through determining the switch state field corresponding to the target service and acquiring the switch state field value corresponding to the switch state field, under the condition that the switch state field value is a preset first value, data synchronization from public cloud to private cloud is not performed, under the condition that the switch state field value is a preset second value, data synchronization from public cloud to private cloud is performed, a synchronization message is sent but the synchronization message is not consumed, under the condition that the switch state field value is a preset third value, data synchronization from public cloud to private cloud is performed, a synchronization message is sent and the synchronization message is consumed, so that the whole process of transferring from private cloud to public cloud to perform deployment is controlled according to the switch state field value, under the condition that the switch state field value is a preset second value, bidirectional synchronization of data between private cloud and public cloud can be realized, consistency of the data is ensured, if the storage middleware of the public cloud is unstable or even fails, user data stored by switching the service back to the public cloud can still be prevented from being accessed by the user data during gray scale.
