[0002] Currently, a service needs to be migrated from a private cloud to a public cloud for deployment. The API code is already deployed on the public cloud, but the storage middleware is deployed on the private cloud. Therefore, data operations require cross-network calls to the storage middleware on the private cloud.

[0003] To avoid cross-network calls to the storage middleware within the service, during the grayscale period of migrating the service from the private cloud to the public cloud for deployment, apply for the public cloud's storage middleware, and synchronize the private cloud and hybrid cloud data to the public cloud through the public cloud's storage middleware.

[0004] Because the storage middleware used in private clouds differs from that used in public clouds, bidirectional data synchronization between the private and public clouds is not possible. If the public cloud storage middleware becomes unstable or even fails, and service is switched back to the private cloud, user data written to the public cloud storage during the grayscale rollout will become inaccessible, resulting in data loss. Summary of the Invention

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0050] In an embodiment of the present invention, it is intended to solve the above-mentioned technical problem that due to the difference between the storage middleware of the private cloud and the storage middleware of the public cloud, it is impossible to achieve two-way synchronization of data between the private cloud and the public cloud. If the storage middleware of the public cloud becomes unstable or even fails, the service will be switched back to the private cloud. Then, the user data written to the public cloud storage during the grayscale period will not be accessible, resulting in user data loss. In fact, during the grayscale period, the user data on the public cloud should also be stored on the private cloud. In this way, the data between different clouds is consistent, and when problems occur in the public cloud, it can be switched back to the private cloud at any time.

[0051] However, due to the involvement of multiple storage middleware, such as MySQL, MongoDB, Redis, and Couchbase, bidirectional synchronization cannot be achieved by relying on the storage middleware's own functions, so it can only be achieved through programs. There are two options for achieving data synchronization through programs. One is to directly perform storage dual writes on the public cloud service. This approach is simple and direct, but its disadvantages are excessive dependencies and a lengthy operation process, which increases interface time and affects interface stability. The second option is to send asynchronous messages from the public cloud service, and deploy separate consumers in the private cloud to consume the messages and write the data to the private cloud for storage. Although this approach is complex, it can achieve data dual writes without affecting normal online business, so the second option was chosen.

[0052] Based on the above invention concept, Figure 1FIG. 1 is a schematic diagram of an implementation process of a hybrid cloud data synchronization method provided by an embodiment of the present invention. The method is applied to a public cloud and may specifically include the following steps:

[0053] S101: Determine a switch status field corresponding to a target service, where the target service is a service that is migrated from a private cloud to a public cloud for deployment.

[0054] In an embodiment of the present invention, a service needs to be migrated from a private cloud to a public cloud for deployment. To control the entire process of migrating from a private cloud to a public cloud, a related switch status field is designed for the service. Different switch status field values ​​correspond to different processing.

[0055] Based on this, the switch status field corresponding to the target service is determined, where the target service is a service being deployed from a private cloud to a public cloud. For example, the switch status field corresponding to service A is determined. This switch status field is stored in the cloud platform configuration center, where service A is a service being deployed from a private cloud to a public cloud.

[0056] S102: Obtain a switch status field value corresponding to the switch status field, and determine whether the switch status field value meets a preset requirement.

[0057] In an embodiment of the present invention, the switch status field is stored in the cloud platform configuration center, and the switch status field value corresponding to the switch status field can be obtained from the cloud platform configuration center. The relationship between the switch status field and the switch status field value is similar to the key-value relationship.

[0058] It should be noted that the switch status field value is determined by the status of the target service being migrated from the private cloud to the public cloud for deployment, such as before grayscale deployment, completion of formal launch, data switching back, etc. The switch status field value is 0, and the embodiment of the present invention does not limit this.

[0059] In addition, for the switch status field value corresponding to the switch status field, it is necessary to determine whether the switch status field value meets the preset requirements, and then decide whether to trigger the synchronization message of the public cloud incremental data to the private cloud based on the judgment result.

[0060] It should be noted that, for the switch status field value corresponding to the switch status field, determining whether the switch status field value meets the preset requirements is essentially determining whether the switch status field value is a preset value, and the embodiment of the present invention does not limit this.

[0061] S103, when the switch status field value meets the preset requirements, trigger the synchronization message of the public cloud incremental data to the private cloud.

[0062] In an embodiment of the present invention, for the switch status field value, it is determined whether it meets the preset requirements, and if it meets the preset requirements, it indicates that a synchronization message is sent and a synchronization message is consumed at the same time, thereby triggering a synchronization message for synchronizing incremental data from the public cloud to the private cloud.

[0063] It should be noted that the synchronization message corresponds to the public cloud incremental data (such as user incremental data), and the public cloud incremental data needs to be calculated in real time, which is not limited in the embodiment of the present invention.

[0064] S104: Send the synchronization message to the message cluster and notify the private cloud consumer to consume the synchronization message in the message cluster, and synchronize the incremental data in the public cloud to the private cloud.

[0065] In an embodiment of the present invention, a synchronization message is sent to a message cluster, and private cloud consumers are notified to consume the synchronization message in the message cluster, so that incremental data in the public cloud can be synchronized to the private cloud. In this way, two-way synchronization of data between the private cloud and the public cloud can be achieved to ensure data consistency.

[0066] It should be noted that the consumer of synchronization messages is pre-set in the private cloud, the public cloud sends the synchronization message to the message cluster, and then the public cloud issues a notification. After the private cloud consumer receives the notification, it consumes the synchronization message in the message cluster and synchronizes the incremental data in the public cloud to the private cloud.

[0067] Through the above description of the technical solution provided by the embodiment of the present invention, by determining the switch status field corresponding to the target service and obtaining the switch status field value corresponding to the switch status field, when the switch status field value meets the preset requirements, 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 notified to consume the synchronization message in the message cluster, and the incremental data in the public cloud is synchronized to the private cloud.

[0068] This allows for two-way synchronization of data between the private cloud and the public cloud, ensuring data consistency. If the public cloud's storage middleware becomes unstable or even fails, the service will be switched back to the private cloud. User data written to the public cloud storage during the grayscale period can still be accessed, preventing user data loss.

[0069] like Figure 2 FIG. 1 is a schematic diagram of an implementation flow of another hybrid cloud data synchronization method provided by an embodiment of the present invention. The method is applied to a public cloud and may specifically include the following steps:

[0070] S201: Determine a switch status field corresponding to a target service, where the target service is a service that is migrated from a private cloud to a public cloud for deployment.

[0071] In the embodiment of the present invention, this step is similar to the above-mentioned step S101, and the embodiment of the present invention will not be described in detail here.

[0072] S202: Obtain a switch status field value corresponding to the switch status field, and determine whether the switch status field value is a preset first value, where the preset first value indicates that a synchronization message is not sent and a synchronization message is not consumed.

[0073] S203: When the value of the switch status field is a preset first value, obtain the status corresponding to the target service.

[0074] S204: Store the incremental data in a public cloud or a private cloud according to the status corresponding to the target service.

[0075] In an embodiment of the present invention, the switch status field is stored in the cloud platform configuration center, so that the switch status field value corresponding to the switch status field can be obtained from the cloud platform configuration center, and it is determined whether the switch status field value is a preset first value, wherein the preset first value indicates that no synchronization message is sent and no synchronization message is consumed, which means that data synchronization from the public cloud to the private cloud is not performed at this time.

[0076] When the switch status field value is the preset first value, the status corresponding to the target service is obtained, and the incremental data is stored in the public cloud or private cloud according to the status corresponding to the target service, which means that the status corresponding to the target service determines whether the incremental data is stored in the public cloud or private cloud.

[0077] For example, obtain the switch status field value corresponding to the switch status field from the cloud platform configuration center, and determine whether the switch status field value is 0. The switch status field value is equal to 0, which means that no synchronization message is sent and no synchronization message is consumed, which means that data synchronization from the public cloud to the private cloud is not performed at this time.

[0078] When the switch status field value is 0, the status corresponding to the target service is obtained. This status is the status before grayscale deployment, the official launch is completed, or the data is switched back. Therefore, according to the status corresponding to the target service, the incremental data is stored in the public cloud or private cloud. Among them, the status of the target service is the status before grayscale deployment or the data is switched back, and the incremental data needs to be stored in the private cloud. The status of the target service is the status of the official launch is completed, and the incremental data needs to be stored in the public cloud.

[0079] It should be noted that for the status corresponding to the target service, this status is the status before grayscale deployment, formal online completion or data switching back. Therefore, the switch status field value can be set to a preset first value, for example, the preset first value is 0, so that data synchronization from the public cloud to the private cloud will not be performed subsequently. The embodiment of the present invention does not limit this.

[0080] S205 , determining whether the switch status field value is a preset second value, where the preset second value indicates that a synchronization message is sent but not consumed.

[0081] S206: When the switch status field value is a preset second value, trigger a synchronization message for synchronizing the public cloud incremental data to the private cloud, and send the synchronization message to the message cluster.

[0082] In an embodiment of the present invention, for the switch status field value corresponding to the switch status field, it is also possible to determine whether the switch status field value is a preset second value. The preset second value represents sending a synchronization message and not consuming the synchronization message. When the switch status field value is the preset second value, a synchronization message is triggered to synchronize the public cloud incremental data to the private cloud, and the synchronization message is sent to the message cluster.

[0083] For example, for the switch status field value corresponding to the switch status field, determine whether the switch status field value is 1, where the switch status field value equal to 1 represents sending a synchronization message but not consuming the synchronization message. When the switch status field value is 1, the synchronization message of the public cloud incremental data to the private cloud is triggered, and the synchronization message is sent to the message cluster.

[0084] It should be noted that when the Switch Status field value is the preset second value (e.g., 1), the target service is in grayscale deployment and is also performing one-way data synchronization from the private cloud to the public cloud. Because of this one-way data synchronization from the private cloud to the public cloud, message synchronization cannot be enabled. Messages are only stored in the message cluster, otherwise data will be duplicated in the public cloud.

[0085] For example, when a user completes a check-in, the API service stores a check-in record in the public cloud. This triggers a synchronization message to synchronize incremental data from the public cloud to the private cloud, and sends the synchronization message to the message cluster. If the corresponding switch status field value is 2, the private cloud consumer consumes the synchronization message and stores a check-in record in the private cloud. If the one-way data synchronization from the private cloud to the public cloud is not disconnected, this check-in record will be synchronized to the public cloud. Consequently, two check-in records for the user will exist in the public cloud, causing data duplication.

[0086] In addition, it should be noted that for the state corresponding to the target service, this state is the state in grayscale deployment, so the switch status field value can be set to a preset second value (for example, 1), and synchronization messages can be sent subsequently but not consumed. The embodiment of the present invention does not limit this.

[0087] S207 , determining whether the switch status field value is a preset third value, where the preset third value indicates sending and consuming synchronization messages.

[0088] S208: When the switch status field value is a preset third value, trigger a synchronization message for synchronizing the public cloud incremental data to the private cloud.

[0089] S209: Send the synchronization message to the message cluster and notify the private cloud consumer to consume the synchronization message in the message cluster, and synchronize the incremental data in the public cloud to the private cloud.

[0090] In an embodiment of the present invention, for the switch status field value corresponding to the switch status field, it is also possible to determine whether the switch status field value is a preset third value. The preset third value represents the sending of synchronization messages and the consumption of synchronization messages. When the switch status field value is the preset third value, a synchronization message is triggered to synchronize the incremental data of the public cloud to the private cloud, and the synchronization message is sent to the message cluster, and the private cloud consumer is notified to consume the synchronization message in the message cluster, and the incremental data in the public cloud is synchronized to the private cloud.

[0091] For example, for the switch status field value corresponding to the switch status field, it is also possible to determine whether the switch status field value is 2. The switch status field value equal to 2 represents sending a synchronization message and consuming a synchronization message. When the switch status field value is 2, the synchronization message of the public cloud incremental data to the private cloud is triggered, and the synchronization message is sent to the message cluster. The private cloud consumer is notified to consume the synchronization message in the message cluster, and the incremental data in the public cloud is synchronized to the private cloud.

[0092] It should be noted that for the status corresponding to the target service, this status is the status of grayscale deployment completion, so the switch status field value can be set to a preset third value, for example, the preset third value is 2, so that synchronization messages will be sent and consumed subsequently. The embodiment of the present invention does not limit this.

[0093] In addition, in an embodiment of the present invention, during the period of sending and consuming synchronization messages, it is necessary to ensure that the one-way data synchronization from the private cloud to the public cloud has been interrupted. Therefore, when the value of the switch status field is a preset third value, it is detected whether the one-way data synchronization from the private cloud to the public cloud has been interrupted. If the one-way data synchronization from the private cloud to the public cloud has been interrupted, a synchronization message for synchronizing incremental data from the public cloud to the private cloud is triggered. If the one-way data synchronization from the private cloud to the public cloud has not been interrupted, the one-way data synchronization from the private cloud to the public cloud is interrupted, and a synchronization message for synchronizing incremental data from the public cloud to the private cloud is triggered.

[0094] For example, when the switch status field value is 2, it detects whether the one-way data synchronization from the private cloud to the public cloud has been interrupted. If the one-way data synchronization from the private cloud to the public cloud has been interrupted, it triggers the synchronization message of the public cloud incremental data to the private cloud, sends the synchronization message to the message cluster, and notifies the private cloud consumer to consume the synchronization message in the message cluster, and synchronizes the incremental data in the public cloud to the private cloud.

[0095] When the one-way data synchronization from the private cloud to the public cloud is not interrupted, the DBA interrupts the one-way data synchronization from the private cloud to the public cloud, and then triggers the synchronization message for synchronizing the incremental data of the public cloud to the private cloud, sends the synchronization message to the message cluster, and notifies the private cloud consumer to consume the synchronization message in the message cluster, and synchronizes the incremental data in the public cloud to the private cloud.

[0096] In addition, synchronization messages have corresponding triggering times. When consuming synchronization messages, private cloud consumers can follow these triggering times, perhaps on a priority-first-consumption basis. Therefore, in this embodiment of the present invention, the public cloud can notify private cloud consumers to consume synchronization messages in the message cluster according to the synchronization message triggering times, synchronizing incremental data from the public cloud to the private cloud.

[0097] It should be noted that for the above steps S202 to S204, S205 to S206, and S207 to S209, that is, the processing steps for determining whether the switch status field value is the preset first value, the preset second value, or the preset third value, the execution order may be, for example, first executing S202 to S204, then executing S205 to S206, and finally executing S207 to S209. The embodiment of the present invention does not limit this.

[0098] Through the above description of the technical solution provided by the embodiment of the present invention, by determining the switch status field corresponding to the target service and obtaining the switch status field value corresponding to the switch status field, when the switch status field value is a preset first value, data synchronization from the public cloud to the private cloud is not performed, and when the switch status field value is a preset second value, data synchronization from the public cloud to the private cloud is performed, and synchronization messages are sent but not consumed. When the switch status field value is a preset third value, data synchronization from the public cloud to the private cloud is performed, and synchronization messages are sent and consumed. In this way, the entire process of migrating from the private cloud to the public cloud for deployment is controlled according to the switch status field value, and when the switch status field value is the preset second value, two-way synchronization of data between the private cloud and the public cloud can be achieved to ensure data consistency. If the storage middleware of the public cloud becomes unstable or even fails, the service is switched back to the private cloud, and the user data written to the public cloud storage during the grayscale period can still be accessed, avoiding user data loss.

[0099] Corresponding to the above method embodiment, the embodiment of the present invention also provides a hybrid cloud data synchronization device, such as Figure 3 As shown, the device may include: a field determination module 310, a field value acquisition module 320, a field value judgment module 330, a message triggering module 340, a message sending module 350, and a data synchronization module 360.
