It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of a method for generating a disaster recovery handover scheme according to one or more embodiments of the present disclosure. The process may be performed by computing devices in the respective domains, with certain input parameters or intermediate results in the process allowing for manual intervention adjustments to help improve accuracy. The analysis method according to the embodiment of the present application may be implemented by a terminal device or a server, and the present application is not limited to this. For convenience of understanding and description, the following embodiments are described in detail by taking a server as an example.
It should be noted that the server may be a single device, or may be a system composed of multiple devices, that is, a distributed server, which is not specifically limited in this application.
As shown in fig. 1, an embodiment of the present application provides a method, including:
s101: confirming a target disaster recovery system corresponding to a target generation task, and acquiring basic data of the target disaster recovery system; the basic data at least comprises system data and application data of the target disaster recovery system.
Firstly, a target disaster recovery system needing to generate a disaster recovery switching scheme is determined, wherein the target disaster recovery system refers to a system formed by a plurality of disaster recovery centers. Basic data of the target disaster-backup system is then obtained, wherein the basic data at least comprises system data and application data of the target disaster-backup system. The system data and the application data are data that can be directly acquired.
The basic data may be stored in a storage device of the computer device in advance, and when the disaster recovery switching scheme needs to be generated, the computer device may select the basic data from the storage device. Of course, the computer device may also obtain the underlying data from other external devices. For example, the basic data is stored in the cloud, and when a disaster recovery switching scheme needs to be generated, the computer device may obtain the basic data from the cloud.
S102: and determining a deployment mode and a switching strategy of the target disaster recovery system according to the basic data.
After the basic data of the target disaster recovery system is acquired, the deployment mode and the switching strategy of the target disaster recovery system need to be determined. The deployment mode refers to the deployment mode of different disaster backup centers in a disaster backup system, taking a traditional main backup mode as an example, in the deployment mode, a service is operated only in one disaster backup center, an enterprise deploys a large number of backup servers in the backup center by combining disaster backup level requirements and service requirements, but the backup center only provides disaster backup services for the service, and only when a disaster occurs and a production data center is paralyzed, the service system of the disaster backup center starts the servers, so that the resource waste of the servers of the backup center is caused, and a wide area network link cannot be fully utilized. The distributed dual-active data center can simultaneously run the same type of service distributed in a plurality of data centers, and can also distribute one service to run in different data centers in a layering manner. If one data center is interrupted, other data centers can still independently respond to the service, and the service switching is not perceived by users. The switching strategy refers to the connection relation between the disaster recovery center and other disaster recovery centers in the process of executing disaster recovery switching.
In one embodiment, when determining the deployment mode and the switching policy of the target disaster recovery system according to the basic data, firstly, the running application type of the target disaster recovery system needs to be determined according to the application data corresponding to the target disaster recovery system in the basic data. The running application type herein refers to the type of application that each disaster recovery center runs. Such as channel type applications, core online transaction systems, non-core big data type applications, etc. And determining a deployment standard model of the target disaster recovery system according to the operation application type and the system data. The deployment standard models are set in advance, are large in number and are respectively suitable for deployment models of different types of disaster recovery systems. And then determining the central level of each disaster recovery center in the target disaster recovery system, wherein the central level can be directly determined according to basic data of the disaster recovery center when the central level is determined. If the disaster recovery system has a disaster recovery center at the level of the main data center, and also has a disaster recovery center at the level of the standby data center. And finally, determining a switching strategy of the target disaster recovery system and a deployment mode of each disaster recovery center according to the center level and the deployment standard model.
Further, before determining a deployment standard model of the target disaster recovery system according to the running application type and the system data, a deployment standard model needs to be generated, and when the deployment standard model is generated, the deployment standard model needs to be generated according to preset thresholds corresponding to parameters such as transaction ratio, access flow, resource ratio, switching strategy and the like. After the deployment standard model is generated, clustering operation needs to be performed on the parameter configuration scheme corresponding to the model, so that a plurality of parameter configuration clusters are generated, and finally, clustering results are stored in a database.
Furthermore, when the deployment standard model of the target disaster recovery system is selected according to the operation application type and the system data, firstly, a first deployment standard model of the target disaster recovery system is determined according to the operation application type of the target disaster recovery system and the opinion application type of the deployment standard model; then, clustering the system data of the target disaster recovery system to determine a second deployment standard model corresponding to the clustering of the system data of the target disaster recovery system; and then determining a deployment standard model of the target disaster recovery system according to the first deployment standard model, the second deployment standard model and a preset proportion.
S103: and configuring the logic node information of the target disaster recovery system according to the deployment mode and the switching strategy.
After the deployment mode and the switching strategy of the target disaster recovery system are obtained, data maintenance needs to be performed on the logic nodes according to the deployment mode and the switching strategy, that is, information of the logic nodes is completely supplemented, that is, the deployment mode and the switching strategy in the logic node information, interface information, access relations between the logic nodes, configuration parameters and other information need to be supplemented.
S104: and generating a disaster recovery switching scheme of the target disaster recovery system according to a disaster recovery switching algorithm, the deployment mode and the switching strategy.
After the data maintenance is completed, a disaster recovery switching algorithm needs to be called, and a disaster recovery switching scheme of the target disaster recovery system is generated according to the deployment mode and the switching strategy.
In an embodiment, when generating the disaster recovery switching scheme of the target disaster recovery system, first, a switching policy of the target disaster recovery system and a deployment mode of each disaster recovery center in the target disaster recovery system need to be determined, then, a data transmission direction of each disaster recovery center in the disaster recovery switching process is determined according to the switching policy of the target disaster recovery system, then, a deployment mode of the local terminal disaster recovery center and a deployment mode of the opposite terminal disaster recovery center in the disaster recovery switching process are determined according to the data transmission direction, and finally, a connection relationship between the local terminal interface and the opposite terminal deployment unit is determined according to the deployment mode of the local terminal disaster recovery center and the deployment mode of the opposite terminal disaster recovery center, so that the disaster recovery switching scheme of the target disaster recovery system is obtained.
In an embodiment, after the disaster recovery switching scheme is generated, in order to facilitate mutual understanding and effective connection of services, development, operation and maintenance, the disaster recovery switching scheme may be visualized, so that a disaster recovery switching view of an application may be viewed at a visualization end, and in addition, server data may be marked in the disaster recovery switching view, where the server data includes at least one of configuration parameter information and running state information of an application server in a target disaster recovery center.
When the disaster recovery switching scheme is used, firstly, a received system disaster recovery switching task triggering instruction needs to be responded, and then the disaster recovery switching task is executed in the disaster recovery system according to the disaster recovery switching scheme. In the course of the execution of the task,
according to a switching strategy in a disaster recovery switching scheme and a deployment mode of each disaster recovery center, determining an access relation between deployment units of a local disaster recovery center and other disaster recovery centers in a disaster recovery switching process, thereby completing a disaster recovery switching task. The switching policy is exemplified by a first switching policy (LO), a second switching policy (AO), and a third switching policy:
the disaster recovery center executing the first switching strategy can only access the deployment unit of the disaster recovery center, so that the method has the advantages of reducing the working content of interface switching, realizing the integral switching of the application only by controlling the external interface switching, and being beneficial to the integral switching of the application. The disadvantage is that the deployment unit needs to be switched with the visitor to realize failure recovery when the deployment unit fails.
The disaster recovery center executing the second switching strategy can access the deployment units of other disaster recovery centers according to the running application requirements, and has the advantages that the deployment units (ADUs) can be flexibly switched, for example, the DNS that the double-center WEB points to the active AP of a certain center, if the AP fails, the DNS is responsible for pointing the IP to the normal AP, so that the recovery can be realized, and the recovery speed is improved. The disadvantages are that: if overall faults occur or more units are deployed, more switching actions of the whole physical subsystem are performed.
The disaster recovery center executing the third switching strategy can simultaneously access the deployment units of a plurality of disaster recovery centers, and the model requires that the interfaces have automatic detection capability and has the advantage of automatic switching; the premise is that stateless applications are required to support the random switching capability of services.
The deployment modes are exemplified by a first deployment mode (A-Active, A mode), a second deployment mode (S-StandBy, S mode), and a third deployment mode (C-Cold, C mode): wherein the first deployment mode provides service operation to the outside. The second deployment mode carries the switching of a single application failure scene, such as emergent switching of a certain accidental application and database exception. The third deployment mode is used for simulation drilling and overall disaster recovery switching, so all configuration interfaces are Local.
On the basis of the three deployment modes, the deployment standard model can be an AAC deployment model, namely, two data centers are the first deployment mode and the other data center is the third deployment mode in the data centers of the two places and the three centers. In addition, the method can also be an ASC deployment standard model, an AS deployment standard model and the like.
On the basis of the three deployment modes and the three switching strategies, the disaster recovery switching algorithm is shown in the following table:
the above table is illustrated by way of example: when the deployment mode of the local terminal is A:
the connection relation between the home terminal interface and the deployment unit is connection; when the opposite terminal mode A is adopted, the connection between the interface and the deployment unit is none, switching and connection respectively; when the opposite terminal mode S is adopted, the connection between the interface and the deployment unit is respectively none, switching and switching; when the terminal mode C is used, the connection between the interface and the deployment unit is none.
