This embodiment is applicable to the situation where a local server is migrated to a cloud computing platform in order to meet business needs. Figure 1 As shown, the server migration system may specifically include: a migration scheduling server 101, at least two local servers 102 to be migrated, a target cloud host 103 corresponding to each of the local servers 102 to be migrated, a migration client application 104 running in each of the local servers 102 to be migrated, and a migration server application 105 running in the target cloud host 103 corresponding to each of the local servers 102 to be migrated. The structure and function thereof are described below.

[0053] Among them, the migration scheduling server 101 is used to create a target cloud host 103 corresponding to each local server 102 to be migrated in the target cloud computing platform according to the migration image corresponding to each local server 102 to be migrated after receiving the migration request corresponding to each local server 102 to be migrated; and send the migration start instruction corresponding to each local server 102 to the migration client application 104 running in each local server 102 to be migrated.

[0054] Each of the migration client applications 104 is used to, after receiving a migration start instruction, determine, according to the migration start instruction, a target cloud host 103 corresponding to the local server 102 to be migrated; determine each data block to be migrated in the local server 102 to be migrated; send each data block to be migrated to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated; and after all the data blocks to be migrated are sent to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated, send a data migration completion prompt message to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated.

[0055] Each of the migration server applications 105 is used to store each data block to be migrated in the disk of the target cloud host 103 after receiving each data block to be migrated; after all the data blocks to be migrated are stored in the disk of the target cloud host 103, install the driver in the target cloud host 103; and control the restart of the target cloud host 103.

[0056] Optionally, a local server cluster is provided in the enterprise. The local server cluster is composed of multiple local servers. The target cloud computing platform is a cloud computing platform that can process the business data of the enterprise. In order to meet the business needs of the enterprise, each local server in the local server cluster can be migrated to the target cloud computing platform, and the business data of the enterprise can be processed by the target cloud computing platform. The migration scheduling server 101 is a server set in the target cloud computing platform for managing the server migration process of migrating local servers to the target cloud computing platform. The cloud hosts of the target cloud computing platform can be virtual machines created on the target cloud computing platform. The local servers 102 to be migrated are the local servers in the local server cluster that need to be migrated to the target cloud computing platform at the current moment. The target cloud host 103 corresponding to the local server 102 to be migrated is the cloud host of the target cloud computing platform to which the business data in the local server 102 to be migrated needs to be migrated.

[0057] Optionally, the migration client application is an application program for sending each data block to be migrated in the local server where the migration client application is located to the migration server application running in the target cloud host corresponding to the local server. The target user installs the written migration client application in advance on the local server 102 to be migrated, and triggers the migration client application to run. The target user may be a technician responsible for managing the local server 102 to be migrated. The migration client application 104 running in the local server 102 to be migrated can be used to send each data block to be migrated in the local server 102 to be migrated to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated.

[0058] Optionally, the migration server application is an application for storing all the data blocks to be migrated received from the local server corresponding to the cloud host in the disk of the cloud host, installing the driver in the cloud host, and controlling the restart of the cloud host. The migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated can be used to store all the data blocks to be migrated received from the local server 102 to be migrated in the disk of the target cloud host 103, and then install the driver in the target cloud host 103 to control the restart of the target cloud host 103. The migration server application can be written by the target user.

[0059] Optionally, for each local server 102 to be migrated, the migration request corresponding to the local server 102 to be migrated is a request for requesting to migrate the local server 102 to be migrated to the target cloud computing platform. The migration request corresponding to the local server 102 to be migrated carries the identification information of the local server 102 to be migrated. The identification information of the local server 102 to be migrated may be a digital number or a string used to uniquely identify the local server 102 to be migrated. The target user may send the migration request corresponding to each local server 102 to be migrated to the migration scheduling server 101 through a terminal device. After receiving the migration request corresponding to each local server 102 to be migrated, the migration scheduling server 101 creates a target cloud host 103 corresponding to each local server 102 to be migrated in the target cloud computing platform according to the migration image corresponding to each local server 102 to be migrated, and then sends the migration start instruction corresponding to each local server 102 to be migrated to the migration client application 104 running in each local server 102 to be migrated.

[0060] Optionally, according to the migration image corresponding to each local server 102 to be migrated, a target cloud host 103 corresponding to each local server 102 to be migrated is created in the target cloud computing platform, including: performing the following operations for each local server 102 to be migrated: uploading the migration image corresponding to the local server 102 to be migrated to the target cloud computing platform; creating a target cloud host 103 corresponding to the local server 102 to be migrated in the target cloud computing platform according to the migration image uploaded to the target cloud computing platform; wherein the operating system of the target cloud host 103 is the same as the operating system of the local server 102 to be migrated, the disk information of the target cloud host 103 is the same as the disk information of the local server 102 to be migrated, the disk information includes the number of disks and the size of the disks, and a migration server application is running in the target cloud host 103. The number of disks may be the total number of disks included. The disk size may be the capacity of each disk included.

[0061] Optionally, the migration image corresponding to the local server 102 to be migrated may be a file used to create a cloud host in the target cloud computing platform, which has an operating system identical to that of the local server 102 to be migrated, disk information identical to that of the local server 102 to be migrated, and runs a migration server application. The migration image corresponding to the local server 102 to be migrated is stored in the migration scheduling server 101. The migration image corresponding to the local server 102 to be migrated includes a creation script corresponding to the local server 102 to be migrated. The creation script corresponding to the local server 102 to be migrated is a script that can be used to create a cloud host in the target cloud computing platform, which has an operating system identical to that of the local server 102 to be migrated, disk information identical to that of the local server 102 to be migrated, and runs a migration server application. The creation script corresponding to the local server 102 to be migrated will perform the following operations after running: create a cloud host in the target cloud computing platform; configure the operating system of the cloud host so that the operating system of the cloud host is the same as the operating system of the local server 102 to be migrated; configure the disk of the cloud host so that each disk in the cloud host corresponds to each disk in the local server 102 to be migrated, and each disk of the local server 102 to be migrated has a unique corresponding disk in the cloud host, and the identification information and capacity of the corresponding two disks are the same, so that the disk information of the cloud host is the same as the disk information of the local server 102 to be migrated; install the migration server application in the cloud host, and trigger the migration server application to run. The identification information of the disk can be a digital number used to uniquely identify the disk. Thus, a cloud host with the same operating system as the operating system of the local server 102 to be migrated, the same disk information as the disk information of the local server 102 to be migrated, and running the migration server application is created in the target cloud computing platform.

[0062] Optionally, the migration scheduling server 101 may upload the migration image corresponding to the local server 102 to be migrated to the target cloud computing platform, and then create a target cloud host 103 corresponding to the local server 102 to be migrated in the target cloud computing platform according to the migration image uploaded to the target cloud computing platform. Creating a target cloud host 103 corresponding to the local server 102 to be migrated in the target cloud computing platform according to the migration image uploaded to the target cloud computing platform includes: running a creation script in the migration image corresponding to the local server 102 to be migrated uploaded to the target cloud computing platform, thereby creating a cloud host in the target cloud computing platform with an operating system identical to that of the local server 102 to be migrated, disk information identical to that of the local server 102 to be migrated, and running a migration server application; and determining the created cloud host as the target cloud host 103 corresponding to the local server 102 to be migrated.

[0063] Optionally, the migration scheduling server 101 may run the creation script in the migration image corresponding to the local server 102 to be migrated uploaded to the target cloud computing platform through a preset interface in the target cloud computing platform. The preset interface in the target cloud computing platform may be an interface set in the target cloud computing platform for triggering the execution of the creation script in the migration image corresponding to the local server 102 to be migrated uploaded to the target cloud computing platform.

[0064] Optionally, the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated establishes a communication connection with the migration scheduling server 101 after running, and information exchange can be performed based on the established communication connection. The migration server application 105 can send the address of the data interface of the migration server application 105 to the migration scheduling server 101. The data interface of the migration server application 105 is an interface set in the migration server application 105 for receiving data or sending data. Other applications or electronic devices can send data to the data interface of the migration server application 105 according to the address of the data interface, thereby sending data to the migration server application 105.

[0065] Optionally, after creating the target cloud host 103 corresponding to the local server 102 to be migrated, the migration scheduling server 101 sends the migration start instruction corresponding to the local server 102 to be migrated to the migration client application 104 running in the local server 102 to be migrated. The migration start instruction corresponding to the local server 102 to be migrated is an instruction for instructing the migration client application 104 to send each to-be-migrated data block in the local server 102 to be migrated to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated, thereby starting the server migration process of the local server 102 to be migrated. The migration start instruction corresponding to the local server 102 to be migrated may carry the identification information of the target cloud host 103 corresponding to the local server 102 to be migrated, and the address of the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated. The identification information of the target cloud host 103 may be a digital number or a character string used to uniquely identify the target cloud host 103.

[0066] Optionally, after receiving the migration start instruction, the migration client application 104 determines the target cloud host 103 corresponding to the local server 102 to be migrated according to the migration start instruction. The local server 102 to be migrated is the local server 102 to be migrated where the migration client application 104 is located. After receiving the migration start instruction, according to the migration start instruction, the target cloud host 103 corresponding to the local server 102 to be migrated is determined, including: after receiving the migration start instruction, extracting the identification information of the target cloud host 103 corresponding to the local server 102 to be migrated in the migration start instruction and the address of the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated; according to the identification information of the target cloud host 103 corresponding to the local server 102 to be migrated, determining the target cloud host 103 corresponding to the local server 102 to be migrated.

[0067] Optionally, the data blocks to be migrated in the local server 102 to be migrated are data blocks in the local server 102 to be migrated that need to be migrated to the target cloud host corresponding to the local server 102 to be migrated. A plurality of data blocks are stored in the local server 102 to be migrated. Each data block is composed of multiple business data. The local server 102 to be migrated stores identification information and storage information of each data block. The identification information of the data block may be a digital number used to uniquely identify the data block. The storage information of the data block may include identification information of the disk storing the data block. Each data block stored in the local server 102 to be migrated needs to be migrated to the target cloud host 103 corresponding to the local server 102 to be migrated. Each data block stored in the local server 102 to be migrated is a data block to be migrated in the local server 102 to be migrated. Determining each data block to be migrated in the local server 102 to be migrated includes: obtaining identification information and storage information of each data block in the local server 102 to be migrated from the local server 102 to be migrated; and determining each data block stored in the local server 102 to be migrated as each data block to be migrated in the local server 102 to be migrated.

[0068] Optionally, sending each data block to be migrated to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated includes: sorting the digital numbers of each data block to be migrated in ascending order to obtain a digital number sorting sequence; starting from the digital number that is first in the digital number sorting sequence, performing the following operations for each digital number: reading the data block to be migrated to which the digital number belongs from the local server 102 to be migrated, and sending the data block to be migrated, the identification information of the data block to be migrated and the storage information to the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated according to the address of the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated to the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated.

[0069] Optionally, in the process of sending each data block to be migrated to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated, when a new data block is stored in the local server 102 to be migrated, the new data block is determined as the data block to be migrated in the local server 102 to be migrated, and the digital number of the new data block is added to the end of the digital number sorting sequence.

[0070] Optionally, after the migration client application 104 reads the data block to be migrated belonging to the last digital number in the digital number sorting sequence from the local server 102 to be migrated, and sends the data block to be migrated, the identification information of the data block to be migrated, and the storage information to the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated according to the address of the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated, it can be determined that all the data blocks to be migrated are sent to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated, and sends data migration completion prompt information to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated. The data migration completion prompt information can be information set in the migration client application 104 to prompt that all the data blocks to be migrated have been sent. Sending data migration completion prompt information to the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated, including: according to the address of the data interface of the migration server application 10 running in the target cloud host 103 corresponding to the local server 102 to be migrated, sending the data migration completion prompt information to the data interface of the migration server application 105 running in the target cloud host 103 corresponding to the local server 102 to be migrated.

[0071] Optionally, the migration server application 105 receives each data block to be migrated, identification information and storage information of each data block to be migrated through a data interface. After receiving each data block to be migrated, the migration server application 105 stores each data block to be migrated in the disk of the target cloud host 103, including: the migration server application 105 performs the following operations for each data block to be migrated received through the data interface: in each disk of the target cloud host 103, determine the target disk whose identification information is the same as the identification information of the disk storing the data block in the storage information of the data block to be migrated; store the data block to be migrated in the target disk. The target cloud host 103 is the target cloud host 103 where the migration server application 105 is located.

[0072] Optionally, after the migration server application 105 stores all the received data blocks to be migrated in the disk of the target cloud host 103 and receives the data migration completion prompt information sent by the migration client application 104, it determines that all the data blocks to be migrated are stored in the disk of the target cloud host 103, and then installs the driver in the target cloud host 103. The driver can be a program for controlling the cloud host to process business data. A driver component can be set in the migration server application 105. The driver component is a component for installing the driver in the cloud host. The migration server application 105 can call the driver component, and install the driver in the cloud host where the migration server application 105 is located through the driver component, thereby installing the driver in the target cloud host 103.
