[0013] Cloud computer is a special cloud host that relies on network transmission and virtualization technology to present computing, storage and network capabilities in the cloud to the terminal in the form of a computer desktop. The main difference between it and cloud host is the use scenario. Cloud host is generally used for information technology (IT) production and continuous operation of business. Cloud computer is generally used for office, home, education and entertainment, and is accessed through a dedicated client, with obvious use / idle period.

[0014] Because cloud computer business has obvious idle scenarios, large cloud service providers can utilize the computing resources of idle cloud computers through reasonable scheduling. The current commonly used solution is to directly shut down the cloud computer virtual machine after the user exits the access for a certain time, and create a cloud computer virtual machine again when the user accesses again. This method is equivalent to shutting down and restarting the traditional computer, and the memory data is lost after starting up. The user can perceive the shutdown.

[0015] Based on this, the embodiments of the present application provide a data processing method, Figure 1 A flowchart of a data processing method provided by the embodiments of the present application is shown in FIG. Figure 1 As shown in the figure, the method comprises: S101, in the case of detecting a first hibernation request of a cloud computer, creating a first hibernation volume and storing the memory data of the first virtual machine to the first hibernation volume to obtain a second hibernation volume; deleting the first virtual machine.

[0016] It should be noted that the first hibernation request is initiated by the user. Detecting the first hibernation request of the cloud computer can be understood as that the cloud management platform receives the first hibernation request initiated by the user.

[0017] In the embodiments of the present application, the first hibernation volume can be understood as an empty volume used for storing the memory file of the cloud computer. The size information of the first hibernation volume is the same as the memory specification of the cloud computer, which can be understood as that the size of the first hibernation volume is consistent with the memory specification of the cloud computer. Creating the first hibernation volume can be understood as that the cloud management platform invokes a storage management service application programming interface (API) to create the first hibernation volume.

[0018] It should be noted that the first virtual machine can be understood as the virtual machine before the hibernation of the cloud computer, and the memory data of the first virtual machine can be understood as the memory data of the cloud computer. The memory data can also be understood as the memory file. Storing the memory data of the first virtual machine into the first hibernation volume to obtain the second hibernation volume can be understood as uploading the memory data into the first hibernation volume to generate the second hibernation volume.

[0019] In the embodiments of the present application, the process of deleting the first virtual machine specifically includes: invoking a virtual machine management program to delete the first virtual machine to release the central processing unit (CPU) and the memory occupied by the first virtual machine.

[0020] It should be noted that invoking the virtual machine management program to delete the first virtual machine to release the CPU and the memory occupied by the first virtual machine can be understood as that the computing management service invokes the virtual machine management program to initiate hibernation, and the virtual machine management program deletes the first virtual machine to release the CPU and the memory occupied by the first virtual machine. After the first virtual machine is deleted, the hibernation of the cloud computer is completed.

[0021] In the embodiments of the present application, the shared storage component can be understood as a block storage. Storing the second hibernation volume into the shared storage component can be understood as storing the second hibernation volume into the block storage.

[0022] S102, in the case that the first wake-up request of the cloud computer is detected, the second hibernation volume is obtained, the second virtual machine is re-created, and the memory data in the second hibernation volume is imported into the second virtual machine, so that the state of the second virtual machine is the same as the state before the first virtual machine is deleted.

[0023] It should be noted that the second wake-up request is initiated by the user. The first wake-up request of the cloud computer is detected, which can be understood as that the cloud management platform receives the first wake-up request of the cloud computer. The second hibernate volume is obtained, which can be understood as that the memory data is obtained from the shared storage component (downloaded from the second hibernate volume stored in the shared memory component). The second virtual machine can be understood as a virtual machine re-created after the first wake-up request of the cloud computer is detected. The memory data in the second hibernate volume is imported into the second virtual machine, which can be understood as that the memory data is obtained from the second hibernate volume and imported into the second virtual machine. The state of the second virtual machine is the same as the state before the first virtual machine is deleted, which can also be understood as that the cloud computer is restored to the state before hibernation.

[0024] The scheme of the embodiment of the application can store the memory data of the first virtual machine into the created first hibernate volume to obtain the second hibernate volume and delete the first virtual machine in the case that the first hibernate request of the cloud computer is detected, which can save resources when the cloud computer hibernates. The second virtual machine is re-created, and the memory data in the second hibernate volume is imported into the second virtual machine in the case that the first wake-up request of the cloud computer is detected, so that the state of the second virtual machine is the same as the state before the first virtual machine is deleted, that is, the cloud computer can be restored to the working state before hibernation, which avoids the user from perceiving shutdown and thus improves user experience.

[0025] In the embodiment of the application, the process of storing the memory data of the first virtual machine into the first hibernate volume to obtain the second hibernate volume specifically includes: sending a second hibernate request to the virtual machine management program; so that the virtual machine management program exports the memory data of the first virtual machine and stores the memory data of the first virtual machine into the first hibernate volume to obtain the second hibernate volume; the second hibernate request carries at least the first hibernate volume.

[0026] It should be noted that the second hibernate request can be understood as a hibernate request initiated by the computing management service to the virtual machine management program. The second hibernate request carries at least the related information of the first hibernate volume, which can be understood as that the second hibernate request carries at least the related information of the first hibernate volume; the related information at least includes an identity (ID) of the first hibernate volume. The second hibernate request is sent to the virtual machine management program, which can be understood as that the computing management service calls the virtual machine management program to initiate hibernation and carries the related information of the first hibernate volume.

[0027] It should be noted that the virtual machine management program exports the memory data of the first virtual machine, and stores the memory data of the first virtual machine to the first hibernation volume to obtain the second hibernation volume, which can be understood as that the virtual machine management program exports the memory data of the first virtual machine, and stores the memory data to the first hibernation volume to obtain the second hibernation volume. The memory data is stored in the first hibernation volume, which can be understood as that the virtual machine program uploads the exported memory data to the block storage to store the memory data in the first hibernation volume in the block storage to obtain the second hibernation volume.

[0028] In the embodiment of the present application, the process of importing the memory data in the second hibernation volume into the second virtual machine includes: sending a second wake-up request to the virtual machine management program; the second wake-up request at least includes the hibernation volume in which the memory data is stored; so that the virtual machine management program obtains the memory data from the second hibernation volume in which the memory data is stored, and imports the memory data into the second virtual machine.

[0029] It should be noted that the second wake-up request can be understood as a wake-up request initiated by the computing management service to the virtual machine management program. The second wake-up request at least carries the second hibernation volume; it can be understood that the second wake-up request at least carries the information of the second hibernation volume. Sending the second wake-up request to the virtual machine management program can be understood as that the computing management service calls the virtual machine management program to initiate a wake-up with the information of the second hibernation volume.

[0030] It should be noted that the virtual machine management program obtains the memory data from the second hibernation volume in which the memory data is stored, and imports the memory data into the second virtual machine, which can be understood as that the virtual machine management program obtains the memory data from the second hibernation volume, and imports the obtained memory data into the second virtual machine. The memory data is obtained from the second hibernation volume, which can be understood as that the virtual machine program downloads the memory data from the block storage, specifically from the second hibernation volume in the block storage.

[0031] In the embodiment of the present application, the process of re-creating the second virtual machine and importing the memory data in the second hibernation volume into the second virtual machine includes: calling the virtual machine management program to re-create the second virtual machine, and pausing the second virtual machine; importing the memory data in the second hibernation volume into the second virtual machine; and starting the second virtual machine, so that the state of the second virtual machine is the same as the state before the first virtual machine is deleted.

[0032] It should be noted that the calling of the virtual machine management program to recreate the second virtual machine and suspend the second virtual machine can be understood as that the computing management service calls the virtual machine management program to recreate the second virtual machine and suspend the second virtual machine. The memory data in the second hibernation volume is imported into the second virtual machine; and the second virtual machine is started, so that the state of the second virtual machine is the same as the state before the first virtual machine is deleted. It can be understood that the virtual machine program downloads the memory data from the block storage, specifically downloads the memory data from the second hibernation volume in the block storage, and imports the obtained memory data into the second virtual machine, so that the state of the second virtual machine is the same as the state before the first virtual machine is deleted; that is, the cloud computer is restored to the state before hibernation.

[0033] For the convenience of understanding, the above scheme is described in detail. The above data processing method can be exemplarily illustrated as a cloud computer hibernation and wake-up method. When the cloud computer is idle, the memory file of the cloud computer is exported through virtualization technology, uploaded to shared storage, and then the cloud computer is closed and deleted, releasing CPU, memory and other computing resources, and retaining cloud hard disk and cloud network. When the user accesses again, the cloud computer virtual machine is recreated, and the saved memory file is imported from the shared storage to restore the cloud computer to the state before shutdown.

[0034] Figure 2 An exemplary flowchart of cloud computer hibernation provided by the embodiment of the application is shown in the figure. Figure 2 As shown in the figure, it includes a cloud management platform, a storage management service, a block storage, a computing management service and a virtual machine management program. The specific steps are as follows: 1. Create a hibernation volume.

[0035] It should be noted that the cloud management platform calls the storage management service to create a hibernation volume.

[0036] 2. Create a volume.

[0037] It should be noted that the storage management service calls the storage cluster in the block storage to create a volume.

[0038] 3. Hibernation interface call passes volume id.

[0039] It should be noted that the cloud management platform initiates a hibernation interface call to the computing management service, passing the volume id.

[0040] 4. Query volume information.

[0041] It should be noted that the computing management service queries the volume information from the storage management service.

[0042] 5. Interface call passes volume information.

[0043] It should be noted that the computing management service initiates an interface call to the virtual machine management program, passing the volume information.

[0044] 6. Exporting the virtual machine memory file.

[0045] It should be noted that the virtual machine manager exports the virtual machine memory file.

[0046] 7. Uploading the memory file to the block storage.

[0047] It should be noted that the virtual machine manager uploads the memory file to the block storage.

[0048] 8. Deleting the virtual machine.

[0049] It should be noted that the virtual machine manager deletes the virtual machine.

[0050] The above method is described in detail. The cloud management platform receives a hibernation request initiated by a user, calls a storage management service API to create an empty volume for storing the memory file of the cloud computer, and the volume size is consistent with the memory specification of the cloud computer; the storage management service calls the storage cluster to create the volume; after the volume is created successfully, the cloud management platform calls the computing management service to initiate hibernation, carrying the ID of the hibernation volume; the computing management service queries the detailed information of the volume from the storage management service using the volume ID; the computing management service calls the virtual machine manager to initiate hibernation, carrying the detailed information of the hibernation volume; the virtual machine manager suspends the virtual machine and exports the memory file; the virtual machine manager uploads the virtual machine memory file to the hibernation volume; the virtual machine manager deletes the virtual machine and releases the occupied CPU, memory, etc., and the hibernation is completed.

[0051] For a cloud computer in hibernation, when a user requests to wake up, since the virtual machine has actually been deleted, it is necessary to create a virtual machine again, import the memory file saved in the shared storage after the creation is successful, and after the import is completed, the virtual machine can be restored to the state before hibernation. Figure 3 An exemplary cloud computer wake-up flowchart is provided for the embodiments of the present application; as shown in Figure 3 The cloud management platform, storage management service, block storage, computing management service, and virtual machine manager are included; the specific steps are as follows: 1. Recovery interface call.

[0052] It should be noted that the cloud management platform initiates a recovery interface call to the computing management service.

[0053] 2. Rescheduling the virtual machine.

[0054] It should be noted that the computing management service reschedules the virtual machine.

[0055] 3. Querying volume information.

[0056] It should be noted that the computing management service queries the volume information from the storage management service.

[0057] 4. The interface call passes the volume information.

[0058] Note that the compute management service initiates an interface call to the virtual machine hypervisor, passing the volume information.

[0059] 5. The virtual machine is recreated.

[0060] Note that the virtual machine hypervisor recreates the virtual machine.

[0061] 6. The saved memory file is restored.

[0062] Note that the virtual machine hypervisor restores the saved memory file from the block storage.

[0063] For ease of understanding, the above steps are described in detail. The cloud management platform receives a user-initiated wake-up request and calls the compute management service to initiate recovery; since the CPU, memory, etc. of the virtual machine have been released during hibernation, the original physical machine where the virtual machine is located may no longer be able to meet the resource requirements, so the compute management service reschedules the virtual machine to a physical node that meets the resource requirements; the compute management service queries the storage management service for detailed information of the hibernation volume; the compute management service calls the virtual machine hypervisor to recreate the virtual machine, carrying the information of the hibernation volume; the virtual machine hypervisor creates the virtual machine and pauses it; the virtual machine hypervisor downloads the saved memory file before shutdown from the shared storage and imports it into the virtual machine, and after successful import, starts the virtual machine, completes the wake-up, and the virtual machine returns to the state before hibernation.

[0064] The scheme of the embodiment of the application actively releases resources and saves the memory file of the cloud computer to the shared storage when the cloud computer is idle, recreates the cloud computer instance when the cloud computer is used again, restores the saved memory file from the shared storage, and utilizes idle computing power without user awareness.
