Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

The embodiment of the application firstly provides an application software disaster recovery method and device, an electronic device and a storage device. The embodiment of the application also provides another application disaster recovery method and device, electronic equipment and storage equipment. The following are specific examples.

In the prior art, software applications running on a local terminal device often have software failures during running, for example, a software crash failure occurs on a client, a communication link between the client and a software server providing services for the software fails to be connected, and the like. For the software fault, a software version is generally upgraded, and a communication link is waited to recover normal communication, or a maintenance mode such as maintenance by a professional is adopted.

In the method, the client is upgraded, and the communication link is waited to recover normal communication, or the communication link is maintained by professional personnel, so that the data transmission between the client and the network server is delayed, and the normal use of the application service by a user is influenced.

In order to solve the above technical problem, the present application provides a disaster recovery method for application software. In order to more clearly show the application software disaster recovery method provided by the present application, an application scenario of the application software disaster recovery method provided by the present application is introduced first.

Referring to fig. 1, fig. 1 is a first application scenario diagram of an application disaster recovery method according to an embodiment of the present application. In this scenario embodiment, the first application 101 is an application running on a client, and the second application 102 is a cloud version of the first application running on a cloud through application virtualization. The cloud version refers to a mode of realizing the application of the version of the client to the cloud. In general, the application of the client is realized mainly by a first application arranged on the local client, and when the running speed of the first application of the local client cannot reach a preset condition or an abnormal condition occurs, the cloud version is pulled up at the cloud to replace the first application version execution program of the local client.

The application virtualization is to decouple an application program from an operating system and provide a virtual operating environment for the application program. The technical principle is that based on an Application/server computing A/S architecture (Application Serving A/S architecture), a technology similar to a virtual terminal is adopted to isolate the human-computer interaction logic (operation of an Application program interface, a keyboard and a mouse, audio input and output, a card reader, printout and the like) of an Application program from the computing logic. When a user accesses an application virtualized by a server, the user computer only needs to transmit the human-computer interaction logic to the server side, the server side sets an independent session space for the user, the computing logic of the application program runs in the session space, the changed human-computer interaction logic is transmitted to the client side and is displayed on corresponding equipment of the client side, and therefore the user can obtain the same access feeling as that of running a local application program.

In the embodiment of the application, the second application is a cloud version of the first application running in a cloud based on application virtualization, the computing logic of the second application is in a cloud server, and the second application and the human-computer interaction logic of the user are in a local client. When the user uses the application program at the local client and the running application program is the second application program to replace the first application program, the content of the second application program is transmitted to the local client terminal, and the display content is displayed on the display interface of the local client terminal. When the fact that the user carries out trigger operation on the display content of the display interface is detected, the local client transmits the trigger operation information of the user to a second application; and the second application calculates and processes the feedback content by adopting the calculation logic of the cloud server in the virtual running environment based on the received trigger operation information, transmits the feedback content to the local client, and displays the feedback content through the display page by the local client so as to enable the user to perform subsequent trigger operation. Therefore, the man-machine interaction logic between the second application and the user is realized through the local client, and the calculation logic of the second application is realized in the cloud server.

For the user, the interface presented to the user through the first application and the interface presented to the user through the second application at the local client are consistent, and the user is unaware of changes in the first application and the second application. The first application and the second application are changed in that the computing logic of the first application is based on the local server, and the computing logic of the second application is based on the cloud server.

The software server 103 provides remote services to the first application 101 of the client via a first communication connection. When the first application 101 reaches a preset switching condition, the client establishes a second communication connection with the cloud server 104, and accesses the second application 102 to the client through the second communication connection; and, a third communication connection is established between the software server 103 and the cloud server 104, and through the third communication connection, the software server 103 provides the software service required by the second application 102.

The work allocation of each part in the application software disaster recovery system is described as follows.

Typically, the first application 101 performs local information processing work on the client for facilitating the processing of the client, and the software server 103 obtains information provided by the client through the first communication connection, and performs more complex data processing tasks or provides a database to which the first application 101 needs to access.

When the first application 101 cannot normally run, the second application of the cloud server 104 is started and replaces the first application 101 of the client; at this time, on one hand, the second application 102 transmits, to the client 105, the content that needs to be displayed on the interface during the execution of the second application through the second communication connection, and the information input by the input device of the client 105 is also transmitted to the second application running on the cloud server 104 through the second communication connection; the information processing work originally performed at the first application 101 of the client, in this scenario, is performed entirely by the second application 102, the client merely acting as a display and input device; moreover, a third communication connection is established between the software server 103 and the cloud server 104, and the software server 103 continues to execute the service originally provided by the first application 101, except that the communication transmission object is changed into the cloud server 104.

Meanwhile, in the normal working process of the client, the client establishes a monitoring process for monitoring the running state of the first application in real time in the first application 101. The monitoring process can be implemented by using a Hook mechanism. Hook is a system mechanism provided in Windows to replace "interrupts" under DOS, with chinese translated as a "Hook" or "Hook". After a hook event has occurred for a particular system event, the program that made the hook event will be notified by the system upon the occurrence of the hook event, and can then respond to the event at a first time.

Therefore, the process of the monitoring mechanism detecting the running state of the first application is as follows:

if it is detected that the first application 101 reaches the preset switching condition, the first application 101 cannot normally execute the program or the speed of executing the program cannot meet the preset running speed threshold, and data cannot be normally transmitted between the first application 101 and the software server 103. In order to avoid that the current running state of the first application 101 affects data transmission between the first application 101 and the software server 103, the second application 102 arranged in the cloud replaces the first application 101, and the second application 102 is accessed to the client through the second communication connection. Specifically, the client establishes a second communication connection with the cloud server, through the second communication connection, the second application displays the display content obtained by the cloud execution program on the display interface of the client, and meanwhile, the input information of the input interface of the client is also transmitted to the second application of the cloud.

That is, after the second application establishes a communication connection with the client through the second communication connection, the data processing capability of the cloud server where the second application is located is adopted to process the data that needs to be processed originally by the first application between the local client and the software server. Therefore, the current running state of the first application is prevented from influencing data processing and transmission efficiency, and meanwhile the second application processes data at the cloud end to improve data processing efficiency.

Wherein, the first application running on the client terminal reaches the preset switching condition, which comprises: detecting that the first application is in an abnormal state; or detecting that the running state of the first application does not meet a preset application running state.

Wherein detecting that the first application is in an abnormal state comprises one or more of:

(1.1) detecting that a first communication connection state between the first application and a software server providing services for the first application is in an abnormal connection state, as shown in fig. 1. In fig. 1, the case where the first application is caused to have an abnormal state is that the first communication connection state between the first application and the software server is in an abnormal connection state.

The method for determining that the first communication connection state between the first application and the software server is in the abnormal connection state may refer to the following description:

for example, monitoring a feedback situation of the software server for a request message of the first application according to preset time, and if it is detected that the first application receives feedback information of the software server within the preset time, determining that a first communication connection between the first application and the software server is in a normal state; and if the first application is not detected to receive the feedback message of the software server within the preset time, determining that the first communication connection between the first application and the software server belongs to an offline state.

The detecting that the first application does not receive the feedback information of the software server within the preset time may be that the first application does not receive the feedback information of the software server for a preset number of times continuously within a preset time period.

The first case described above is a case where the first application running on the client terminal reaches a preset switching condition due to the first communication connection between the first application and the software server being in an abnormal connection state.

In addition, the first application running on the client side reaching the preset switching condition may further include that the first application itself has an abnormal condition:

please refer to fig. 2, which is a second application scenario diagram of an application disaster recovery method according to an embodiment of the present application.

(1.2) detecting that the first application cannot be started normally. For example, if the first application cannot normally run after being started within the preset number of times, it is determined that the local application cannot be normally started.

As shown in fig. 2, when the first application 101 is in a state that the first application cannot be normally started, the monitoring mechanism monitors the running state of the first application, and if it is detected that the first application cannot be started within a preset number of times, it is determined that the first application is in an abnormal state, alarm information that the first application is in the abnormal state is sent to the software server, and a request for starting the cloud application is sent to the software server.

(1.3), detecting that the first application is damaged, for example, detecting that an important SDK in the first application is deleted, and the like. SDK is a software tool development kit, which is generally a collection of development tools used by some software engineers to build application software for a particular software package, software framework, hardware platform, operating system, and the like. For example, if a face recognition SDK software toolkit provided for certain instant messaging software is deleted by mistake, the communication software cannot perform face recognition login, and a second application may need to be started.

(1.4) detecting that the first application is a software version with a serious problem, for example, the current software version of the first application belongs to a version with a security vulnerability, and notifying.

(1.5) receiving the abnormal alarm information of the first application version, for example, obtaining the current version of the first application sent by the cloud server has a serious problem.

In addition, detecting that the running state of the first application does not meet a preset application running state includes one or more of the following cases:

(2.1) detecting that the running speed of the first application does not meet a preset running speed threshold value.

(2.2) detecting that the running state of the first application can not meet the standard user experience of the user.

And (2.3) detecting abnormal information of an operating system operated by the first application.

And (2.4) detecting that abnormal communication connection exists between the first application and the geographical area where the first application is located.

The monitoring process detects the running state of the first application in real time, if the first application does not reach the preset switching condition, the first application runs normally, and in the running process, data required by normal running are transmitted between the first application and the software server according to function distribution through first communication connection.

When the first application reaches a preset switching condition, the monitoring process sends alarm information that the first application is in an abnormal state to the software server, and the alarm information can be processed by a local abnormal processing process of the client side or the software server by providing a switching link instruction.

The processing procedure of the local switching first application processing process of the client side is as follows: after receiving alarm information for switching the first application, calling a first application switching processing process located locally at the client, sending a first request for establishing communication connection to a cloud server by the first application switching processing process, starting the second application 102 by the cloud server according to the first request, and establishing a second communication connection between the second application 102 and the client after the second application 102 runs so as to transmit display data and input data between the client and the second application.

The processing process of the exception handling process of the software server comprises the following steps: after receiving the anomaly alarm information, the cloud server 104 sends a switching link instruction to the client, where the switching link instruction may include a switching suggestion prompt at the client, and a user may trigger switching according to the switching suggestion prompt, so that the client sends a first request to the cloud server 104, where the cloud server is expected to take over the first application 101, and a subsequent processing process is completely consistent with a processing process of a local anomaly processing process of the client. Of course, the client may be directly instructed to perform the switching process according to the switching link instruction without the step of prompting the user.

Here, the second application accesses the client and may be implemented through a dedicated application program interface API. An API (Application Programming Interface) is a predefined Interface (e.g. function, HTTP Interface) or a convention for linking different components of a software system. An application program interface to provide applications and a set of routines that developers have access to based on certain software or hardware without accessing source code or understanding details of internal workings. In the technical solution, the API only needs to display the content that needs to be displayed after the second application 102 is run on the client through the API interface, that is, the display interface of the client is utilized; in addition, the input of the client needs to be transmitted to the second application 102, and therefore, it is also possible to use the input interface of the client.

The second application is accessed to the client through a second communication connection, specifically, the client establishes a second communication connection with the second application 102 in the cloud server, through the second communication connection, display content obtained by the second application executing a program at the cloud is sent to the client, and the content is displayed on a display page of the client; and simultaneously, the input information provided by the input interface of the client is also sent to the second application through the second communication connection. The input information of the input interface of the client may be edit information of the input interface of the client by a user, or input information obtained by a selection operation of the user for a plurality of candidate information of the input interface of the client.

In addition, the process that the second application accesses the client further comprises the following steps: the second application performs data synchronization with the client in relation to the first application. That is, the relevant data of the first application is synchronized to the second application. For example, if the first application is a picture processing software and needs to process an image captured locally by the client, the picture to be processed may need to be transmitted to the cloud server through a data synchronization mechanism for processing by the second application 102. The data synchronization may be a transaction that needs to be performed during the second application 102 takes over the first application 101, or a transaction that needs to be performed after taking over according to the operation needs.

In addition, the second application is accessed to the client instead of the first application execution program, wherein the software server may further need to establish a third communication connection with the cloud server, and through the third communication connection, the software server provides the second application with the software service required by the second application.

For example, the software server stores data related to the first application, and when the second application is accessed to the client, data transmission is performed between the client and the second application through the second communication connection. If the relevant data of the first application is related, the data of the first application is synchronized into the second application through a data synchronization unit, and specifically, the software server provides the data relevant to the first application for the second application; at this time, the data synchronization process is performed between the software server and the cloud server through the third communication connection.

When the first application running on the client reaches the preset switching condition, the second application of the cloud is accessed to the client to replace the specific description of the first application execution program.

According to the application software disaster recovery method provided by the embodiment of the application software disaster recovery method, when the first application running on the client side reaches the preset switching condition, the second application running on the cloud side is accessed to the client side through the second communication connection to replace the first application, and the second application is a cloud side version of the first application running on the cloud side. At this time, the generated display content obtained by the cloud execution program of the second application is displayed on the display interface of the client through the second communication connection, and meanwhile, the input information in the input interface of the client is also transmitted to the second application through the second communication connection. Therefore, according to the method, the second application of the cloud is accessed to the client to replace the first application to continue executing the program under the condition that the first application running on the client reaches the preset switching condition, and the fault maintenance time of the first application is saved. In addition, through the second communication connection, the display content generated by the cloud execution program is displayed on the display interface of the client by the second application, and the input information of the input interface of the client is also transmitted to the second application at the cloud, so that the problem that data transmission between the first application and the server is blocked when the first application breaks down is avoided.

First embodiment

Fig. 3 is a flowchart of an application disaster recovery method according to a first embodiment of the present application, where the method includes the following steps.

Step S301: responding to that a first application running on a client reaches a preset switching condition, and accessing a second application arranged at a cloud end to the client through a second communication connection so as to replace the first application; the second application is a cloud version of the first application running in a cloud through application virtualization.

The step is used for establishing a second communication connection when detecting that the first application reaches a preset switching condition, and accessing the second application to the client to replace the first application execution program. Specifically, after the second application establishes communication connection with the client through the second communication connection, the data processing capability of the cloud server where the second application is located is adopted to process the items which need to be processed originally by the first application at the local client.

In the embodiment of the application, the second application is a cloud version of the first application running in a cloud based on application virtualization, the computing logic of the second application is in a cloud server, and the second application and the human-computer interaction logic of the user are in a local client. When the user uses the application program at the local client and the running application program is the second application program to replace the first application program, the content of the second application program is transmitted to the local client terminal, and the display content is displayed on the display interface of the local client terminal. When the fact that the user carries out trigger operation on the display content of the display interface is detected, the local client transmits the trigger operation information of the user to a second application; and the second application calculates and processes the feedback content by adopting the calculation logic of the cloud server in the virtual running environment based on the received trigger operation information, transmits the feedback content to the local client, and displays the feedback content through the display page by the local client so as to enable the user to perform subsequent trigger operation. Therefore, the human-computer interaction logic between the second application and the user is realized through the local client, and the computing logic of the second application is realized through the cloud server.

And the data obtained by the second application execution program is transmitted between the second application and the client through the second communication connection. The display content obtained by the second application execution program is displayed on the display interface of the client, and the input information of the input interface of the client is transmitted to the second application.

The running state of the first application is detected in real time through a monitoring process, and the monitoring process is established in the local application. The monitoring process is realized by adopting a Hook mechanism. Hook is a system mechanism provided in Windows to replace "interrupts" under DOS, with chinese translated as a "Hook" or "Hook". After a hook event has occurred for a particular system event, the program that made the hook event will be notified by the system upon the occurrence of the hook event, and can then respond to the event at a first time.

Typically, data is transmitted between the first application and the software server over a first communication connection.
