[0002] With the growth of business volume and the expansion of business scope, a single computer room often cannot provide stable and reliable services. In this case, deploying multiple computer rooms is a common choice, where each computer room can provide several services to the outside world, and each service usually relies on one or more components to implement. At the same time, in practice, there is often a need to switch the services provided by one computer room to another. For example, if the access pressure of a computer room is high, service switching is required. Only by switching services can stable services continue to be provided to the business side.

[0003] In the prior art, service switching can usually only be performed manually, which has low switching efficiency and causes long-term service failures. Therefore, a solution that can efficiently perform service switching is urgently needed. Summary of the invention

[0028] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0029] Figure 1 The flowchart of the control method for multi-computer room service switching provided by an embodiment of the present invention is shown. The method controls the state of at least one component that the service depends on by the switching control platform, completes the switching of the service from the source computer room to the target computer room, and realizes the rapid switching of the service. Figure 1 As shown, the method comprises the following steps:

[0030] Step S110: Based on a cross-machine-room switching request from a source machine room to a target machine room of any service, determine at least one component that the service depends on; and send a first linkage control command to at least one component of the source machine room.

[0031] The switching request may be initiated by an administrator, or may be automatically initiated after the switching control platform detects that the switching conditions are met. In addition, the source computer room is the computer room currently providing the service, and the target computer room is the computer room that provides the service after the service switching is completed. The target computer room may be determined by designation, or may be determined by the switching control platform matching the service requirements with the configurations of each computer room.

[0032] Specifically, after receiving the switching request, the switching control platform determines at least one component that the service depends on, for example, a storage database that the service depends on. It should be noted that multiple computer rooms are deployed with at least one component of each service. Even if the computer room does not currently provide a certain service, the component of the service will be deployed for use after the service is switched.

[0033] Then, the switching control platform sends a first linkage control command to the at least one component of the source computer room to prepare the at least one component of the source computer room for service switching, wherein, when there are multiple at least one component, the first linkage control command is a command for controlling the multiple components at the same time to achieve parallel control of the multiple components.

[0034] In addition, it should be noted that in the embodiments of the present invention, only the switching of any one service is used for illustration. In practice, if there are multiple services with switching requirements, each of the multiple services can be switched in the manner of the embodiments of the present invention, and the switching process of the multiple services can be completed by the parallel control of the switching control platform, thereby improving the efficiency of switching multiple services.

[0035] Step S120: at least one component of the source computer room prohibits data writing and / or stops consumption according to the first linkage control command.

[0036] When the service is provided by the source computer room, at least one component on which the service depends and deployed in the source computer room provides read and write functions, and / or provides production and consumption functions, while at least one component on which the service depends and deployed in the remaining computer rooms (including the target computer room) does not provide write functions, and / or does not provide production and consumption functions.

[0037] The at least one component of the source computer room turns off the data writing function and / or consumption function according to the first linkage control command to avoid adding new service data in the at least one component. Among the at least one component of the source computer room, different components may provide different functions. For example, the MySQL component provides data reading and writing functions, while the Redis QueueProxy component provides production and consumption functions.

[0038] Step S130: at least one component of the source computer room synchronizes data with at least one component of the target computer room; after data synchronization is completed, a second linkage control command is sent to at least one component of the target computer room.

[0039] In practice, components deployed in peer-to-peer fashion between the source computer room and other computer rooms will maintain data synchronization. However, due to latency, it is not possible to ensure that the data is always strictly consistent. In addition, since synchronization is performed from the source computer room to other computer rooms, the data in the source computer room is the most complete.

[0040] Specifically, after at least one component in the source computer room turns off the write function and / or the consumption function, data synchronization is performed from at least one component in the source computer room to at least one component in the target computer room until the data in at least one component in the target computer room is synchronized to be the same as the data in at least one component in the source computer room, and then the data synchronization is completed. Then, the switching control platform sends a second linkage control command to at least one component in the target computer room to control at least one component in the target computer room to prepare to provide services.

[0041] Step S140: at least one component of the target computer room allows data writing and / or allows production and consumption according to the second linkage control command, thereby completing service switching.

[0042] At least one component of the target computer room opens the data writing function and / or consumption function according to the second linkage control command. After the above processing, at least one component of the target computer room has both the data reading and writing function and / or both the production and consumption functions, and can provide services to the outside world.

[0043] According to the control method for multi-computer room service switching provided by the present embodiment, for a switching request of any service, at least one component on which the service depends is determined; a first linkage control command is sent to at least one component in the source computer room, and at least one component in the source computer room is controlled in parallel to prohibit data writing and / or stop consumption processing, so as to prepare for data synchronization and avoid generating new data during the synchronization process; after responding to the first linkage control command, at least one component in the source computer room synchronizes data with at least one component in the target computer room, so that the data in at least one component in the target computer room remains completely consistent with that in the source computer room, so as to avoid data omission; after the data synchronization is completed, a second linkage control command is sent to at least one component in the target computer room, and at least one component in the target computer room is controlled in parallel to allow data writing and / or allow production and consumption. After that, at least one component in the target computer room has data reading and writing functions, and / or production and consumption functions, and can provide the service externally. It can be seen that the scheme of this embodiment, under the premise of controlling that no new service data is generated, synchronizes data from the source computer room to the target computer room, thereby avoiding data omissions and ensuring that the target computer room can provide the service consistent with the source computer room; and, through linkage control commands, controls the functions provided by at least one component in the source computer room and the target computer room in parallel, thereby achieving rapid switching of services.

[0044] Figure 2 FIG. 2 is a flow chart showing a control method for multi-machine room service switching provided by another embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0045] Step S210: Based on a cross-machine-room switching request from a source machine room to a target machine room of any service, determine at least one component that the service depends on; and send a first linkage control command to at least one component of the source machine room.

[0046] In this embodiment, at least one component is mainly used as a storage component for explanation, which includes but is not limited to at least one of the following components: MySQL component, MongoDB component, Codis component, Redis Queue Proxy component and RabbitMQ Proxy component, wherein MySQL, MongoDB, Codis, Redis Queue Proxy and RabbitMQProxy are all structures for storage; and MySQL (a relational database management system) component, MongoDB (a database based on distributed file storage) component and Codis (a distributed Redis solution) use DRC (Data Replicate Center) to achieve real-time data synchronization in two computer rooms; RedisQueue (redis queue) and RabbitMQ (a message queue service) have developed corresponding Proxy middleware to realize production and consumption in the two computer rooms.

[0047] Specifically, the initiator initiates a switching request to switch any service from the source computer room to the target computer room to the switching control platform. After receiving the switching request, the switching control platform determines at least one component that the service depends on, and the at least one component is deployed in each computer room. The switching control platform sends a first linkage control command to the at least one component in the source computer room to control the at least one component in the source computer room to prepare for service switching.

[0048] Step S220: at least one component of the source computer room prohibits data writing and / or stops consumption according to the first linkage control command.

[0049] Specifically, the at least one component in the source computer room can be controlled by the first linkage control command to prohibit data writing and / or stop consumption at the same time, wherein each component provides its own corresponding function, and under the control of the first linkage control command, each component will perform different processing. Optionally, the MySQL component, MongoDB component and / or Codis component of the source computer room prohibit data writing according to the first linkage control command; and / or, the Redis Queue Proxy component and / or the RabbitMQ Proxy component stop consumption according to the first linkage control command. After the at least one component in the source computer room prohibits data writing and / or stops consumption, the at least one component in the source computer room will no longer generate new service data.

[0050] Figure 3 FIG. 1 shows a diagram of the function switch of at least one component before responding to the first linkage control command in a specific example. Figure 3 As shown, a service of the business APP depends on components 1 to 5, which can be MySQL component, MongoDB component, Codis component, Redis Queue Proxy component and RabbitMQ Proxy component respectively. Before the response, components 1, 2 and 3 of the source computer room are readable and writable, and components 4 and 5 can produce and consume, while components 1, 2 and 3 of the target computer room are readable but not writable, and components 4 and 5 cannot produce or consume.

[0051] Figure 4 Shows the corresponding Figure 3 Example of a functional switch status diagram of at least one component after responding to the first linkage control command. Figure 3 The difference is that Figure 4 After responding to the first linkage control command, components 1, 2 and 3 in the source computer room change from readable and writable to readable and non-writable, and components 4 and 5 change from producible and consumable to producible and non-consumable. Then, the five components in the source computer room will not generate new storage data.

[0052] Step S230: at least one component of the source computer room synchronizes data with at least one component of the target computer room; after data synchronization is completed, a second linkage control command is sent to at least one component of the target computer room.

[0053] When at least one component in the source computer room no longer generates new service data, the at least one component in the source computer room synchronizes data with the at least one component in the target computer room, and completes synchronization of data in the at least one component in the target computer room that has not been fully synchronized due to delay, so that the data in the at least one component in the source computer room and the target computer room remain completely consistent. Figure 4 For example, in the Figure 4 In the state shown, components 1 to 5 in the source computer room synchronize data with corresponding components 1 to 5 in the target computer room respectively. And, after completing data synchronization, a second linkage control command is sent to at least one component in the target computer room to control at least one component in the target computer room to prepare to provide the service.

[0054] In some optional embodiments of the present invention, after data synchronization is started (that is, after at least one component of the source computer room prohibits data writing and / or stops consumption according to the first linkage control command), the following method is used to detect whether data synchronization from the source computer room to the target computer room is completed: marking data is written to at least one component of the source computer room, specifically as the latest data written to each computer room in at least one component of the source computer room, and the marking data only serves as a mark and is not used as service data; the marking data is queried in at least one component of the target computer room, and if the marking data is queried, it is determined that data synchronization is completed, wherein, if the latest written marking data is queried in at least one component of the target computer room, it indicates that the stored data before the marking data has been synchronized, and then the switching control platform can be triggered to send a second linkage control command. For example, if at least one component includes MySQL component, MongoDB component and Codis, a piece of marking data is written to the MySQL component, MongoDB component and Codis component of the source computer room at the same time, and then the MySQL component, MongoDB component and Codis component are checked in the target computer room to see if the data can be found. If so, it means that the data of the two computer rooms have been synchronized and reached consistency. This optional implementation method can accurately detect whether the data synchronization is completed by writing marking data, and then can timely trigger the sending of the second linkage control command after the data synchronization is completed, so as to achieve seamless connection between the previous and next processes, which is conducive to speeding up the entire switching process.

[0055] In some other optional embodiments of the present invention, after data synchronization is completed, the synchronization direction of the target component in at least one component is switched between the source computer room and the target computer room. For some target components, which do not support bidirectional synchronization themselves, after data synchronization is completed, data synchronization from the target computer room to the source computer room is achieved by modifying the synchronization direction, that is, the synchronization direction of the target component in the source computer room is switched from copying out to syncing in, and the synchronization direction of the target component in the target computer room is switched from syncing in to copying out, so that the newly generated service data in the target computer room can be synchronized to the source computer room. In addition, if there are other computer rooms besides the source computer room and the target computer room, the synchronization direction of the target component in the other computer room remains unchanged. Specifically, the target component may include a MySQL component and / or a MongoDB component, and the switching of the synchronization direction of the DRC of the MySQL component and / or the MongoDB component between the source computer room and the target computer room is achieved by switching the synchronization direction of the DRC of the MySQL component and / or the MongoDB component. Among them, MySQL component, MongoDB component and Codis component all use DRC to achieve real-time data synchronization. Among them, MySQL component and MongoDB component do not support two-way synchronization, so the synchronization direction of DRC needs to be modified. On the contrary, Codis component itself supports two-way synchronization and does not need to be modified. The above optional implementation method, after the data synchronization is completed, can ensure that the newly generated service data in the subsequent target computer room during the process of providing the service can be synchronized to the source computer room in a timely manner by modifying the synchronization direction of some target components.

[0056] Step S240: at least one component of the target computer room allows data writing and / or allows production and consumption according to the second linkage control command.

[0057] Specifically, the at least one component in the target computer room can be controlled by the second linkage control command to allow data writing and / or consumption at the same time, wherein each component provides its own corresponding function, and under the control of the first linkage control command, each component will perform different processing. Optionally, the MySQL component, MongoDB component and / or Codis component of the target computer room allow data writing according to the second linkage control command; and / or, the Redis QueueProxy component and / or the RabbitMQ Proxy component allow consumption according to the second linkage control command. After the at least one component in the target computer room allows data writing and / or allows production and consumption, it is the same as the function switch state of at least one component in the source computer room before responding to the first linkage control command. At this time, at least one component in the target computer room is ready to provide the service.

[0058] Furthermore, after completing data synchronization, the switching control platform also sends a third linkage control command to at least one component in the source computer room to control at least one component in the source computer room to completely stop the service. At least one component in the source computer room stops production processing according to the third linkage control command, and thereafter the at least one component in the source computer room no longer has the data writing function and / or the production and consumption function, that is, the function switch state of at least one component in the target computer room is the same as that before responding to the first linkage control command.

[0059] Figure 5 Shows the corresponding Figure 3 Example of the function switch status of at least one component after responding to the second linkage control command and the third linkage control command. Figure 4 The difference is that Figure 5 After responding to the second linkage control command, components 1, 2 and 3 in the target computer room change from non-writable to readable and writable, and components 4 and 5 change from non-production and non-consumption to production and consumption; and, after responding to the third linkage control command, components 4 and 5 in the source computer room change from production and non-consumption to non-production and non-consumption.

[0060] Through the above steps S210 to S240, the function conversion of the storage components that the service depends on in the source computer room and the target computer room is completed, and the data synchronization is completed, that is, the switching of the storage layer is completed.

[0061] Step S250: Send a traffic switching notification to the initiator of the switching request to instruct the initiator to migrate the traffic for the service to the target computer room to complete the service switching.

[0062] The switching control platform sends a traffic switching notification to the initiator of the switching request. The initiator migrates the traffic of the service from the source computer room to the target computer room. At this time, the traffic of the service can be carried by the target computer room, completing the service switching.

[0063] According to the control method for multi-computer room service switching provided by this embodiment, for a switching request of any service, at least one component that the service depends on is determined; a first linkage control command is sent to at least one component in the source computer room, and at least one component in the source computer room is controlled in parallel to prohibit data writing and / or stop consumption processing, so as to avoid generating new data during the synchronization process, so as to prepare for data synchronization; after responding to the first linkage control command, at least one component in the source computer room synchronizes data with at least one component in the target computer room, so that the data in at least one component in the target computer room is kept completely consistent with that in the source computer room, so as to avoid data omission; during the synchronization process, data synchronization can be detected by writing marker data Whether it is completed, the switching control platform is triggered in time to send the second linkage control command to achieve seamless connection between the previous and next processes, which is conducive to speeding up the entire switching process; after the synchronization is completed, the synchronization direction of the target component is switched so that the newly generated service data in the target computer room can be synchronized to the source computer room; and, after the synchronization is completed, a second linkage control command is sent to at least one component of the target computer room, and at least one component of the target computer room is controlled in parallel to allow data writing and / or production and consumption. At this time, at least one component of the target computer room is ready to provide services and the switching of the storage layer is completed; then, traffic migration is performed so that the target computer room carries the service traffic and provides services. It can be seen that the scheme of this embodiment, through the switching control platform to control at least one component that the service depends on in the source computer room and the target computer room in parallel, efficiently completes the switching of the storage layer, and ensures that data is not lost.
