[0052] Figure 1 The illustration shows an application scenario of a memory adjustment method provided in an embodiment of this application, such as... Figure 1 As shown, the scenario includes multiple virtual terminals 110, such as virtual terminal 1 111, virtual terminal 2 112, virtual terminal 3 113, ..., virtual terminal n, and server 100, wherein multiple virtual terminals 110 are created by server 100.

[0053] Multiple virtual terminals 110 can be configured on multiple terminal devices. These terminal devices can access the network and communicate with the server 100 via cellular mobile communication technology, which may include 5th Generation Mobile Networks (5G) technology. Alternatively, multiple terminals can access the network and communicate with the server 100 via short-range wireless communication, which may include Wireless Fidelity (Wi-Fi) technology. A terminal device is a device that can provide voice and / or data connectivity to a user, including handheld terminal devices with wireless connectivity, vehicle-mounted terminal devices, etc.

[0054] Furthermore, multiple terminals include, but are not limited to: mobile phones, tablets, laptops, handheld computers, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminal devices in industrial control, wireless terminal devices in autonomous driving, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, or wireless terminal devices in smart homes, etc.

[0055] Server 100 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0056] In one possible implementation, when the server allocates memory to multiple virtual terminals, it typically allocates the same amount of memory to each virtual terminal. However, in some scenarios or for some users, the memory resources required are far less than the memory allocated to the virtual terminals by the server, resulting in low memory resource utilization in the virtual terminals and wasting memory resources.

[0057] Therefore, in order to solve the above problems, embodiments of this application provide a memory adjustment method. Figure 2 A flowchart of a memory adjustment method provided in an embodiment of this application is shown, as follows: Figure 2 As shown, the method may include the following steps:

[0058] Step S201: Obtain memory statistics information of the first virtual terminal.

[0059] In one possible embodiment, the first virtual terminal can be any one of multiple virtual terminals created by the server. Therefore, the server can access each created virtual terminal, including the first virtual terminal. The server can determine the memory statistics of the first virtual terminal in various ways. For example, the server can send an information retrieval command to the first virtual terminal after a set time interval. After receiving the information retrieval command, the first virtual terminal can send memory statistics to the server, and the server can receive the memory statistics sent by the first virtual terminal. The server can also view the performance and memory usage of the virtual terminal through VMware's vSphere Client or vCenter Server. The server can also use PowerCLI scripts to obtain detailed memory statistics. The server can also use API interfaces provided by various platforms to obtain the memory statistics of the virtual terminal. In Windows systems, the server can use PowerShell to view memory statistics, and in Linux systems, the `free -m` command can be used to view memory statistics. This application does not limit the specific method by which the server obtains memory statistics.

[0060] In one possible embodiment, the memory statistics obtained by the server may include the size of multiple types of memory space. These multiple types of memory include at least free memory and first-class memory. The priority of first-class memory is lower than that of free memory. That is, in determining elastic memory, we can first consider how much free memory can be used as elastic memory, and then consider how much first-class memory can be used as elastic memory. For example, when the size of free memory and first-class memory is the same, the elastic memory that can be converted from free memory is greater than the elastic memory that can be converted from first-class memory. Therefore, we can prioritize considering how much free memory can be used as elastic memory, and then consider how much first-class memory can be used as elastic memory. Here, the first-class memory may be the memory occupied by processes. Multiple types of memory can also include a second type of memory, where the priority of the second type of memory is lower than that of the first type of memory. That is, in determining the elastic memory, we can first consider how much of the first type of memory can be used as elastic memory, and then consider how much of the second type of memory can be used as elastic memory. For example, when the size of the second type of memory and the first type of memory are the same, the elastic memory that the first type of memory can be converted into is greater than the elastic memory that the second type of memory can be converted into. Therefore, we can first consider how much of the first type of memory can be used as elastic memory, and then consider how much of the second type of memory can be used as elastic memory. The second type of memory can be the memory occupied by file cache.

[0061] Specifically, process memory usage refers to the amount of memory used by a running process in the system. This can include dynamic data during program execution, memory used to store local variables during program calls, etc. File cache memory usage refers to the memory used by the operating system to cache frequently used data in the file system (such as file content, directory structure, etc.). When a process requests to read a file, the operating system can directly provide the data from the cache instead of reading it from the disk every time. Caching can significantly improve file access speed. Therefore, compared to the other two types of memory, the proportion of file cache memory usage can be reduced by compressing it.

[0062] In addition to the size of various types of memory space, the memory statistics obtained by the server can also include statistics on the used memory and the initial memory configured by the server for the first virtual terminal when it is created.

[0063] Step S202: Determine the elastic memory of the first virtual terminal based on the space size of multiple types of memory.

[0064] In one possible embodiment, the memory usage ratio of the first virtual terminal can be determined first based on the memory statistics of the first virtual terminal. For example, if the memory statistics include 6G of used memory and the server configures 8G of initial memory for the first virtual terminal when creating it, then the memory usage ratio of the first virtual terminal can be determined to be 6G / 8G = 75%.

[0065] After determining the memory usage ratio of the first virtual terminal, the elastic memory allocation strategy can be further determined. Typically, two thresholds can be set: a first threshold and a second threshold, to detect whether there is memory pressure in the first virtual terminal. If the memory usage ratio is less than or equal to the first threshold, the elastic memory allocation strategy can be determined as the first strategy, which is Mi_qos = (free*A + anon*B + file*C), where Mi_qos is the size of elastic memory, free is the size of free memory, A is the first weight corresponding to free memory, anon is the size of memory occupied by processes in the first virtual terminal, B is the second weight corresponding to memory occupied by processes, file is the size of memory occupied by file cache in the first virtual terminal, and C is the size of memory occupied by file cache. The corresponding third weight is stored. Since the memory usage ratio is relatively small, the first strategy, which has a greater impact on the use of the first virtual terminal, can be selected. If the memory usage ratio is greater than the first threshold but less than the second threshold, the elastic memory determination strategy can be determined as the second strategy, which is Mi_qos = (free * A + anon * B), where Mi_qos, free, anon, A, and B are the same as those represented in the first strategy. The second strategy has a smaller impact on the use of the first virtual terminal. If the memory usage ratio is greater than or equal to the second threshold, the elastic memory determination strategy can be determined as the third strategy, which is Mi_qos = free * A, where Mi_qos, free, and A are the same as those represented in the first strategy. The third strategy has no impact on the use of the first virtual terminal.

[0066] It should be noted that A, B, and C can be any numbers from 0% to 100%. Generally, A>B>C, but this application does not limit the specific values ​​of A, B, and C. Furthermore, this application currently classifies memory types into three categories, and can classify memory types into more categories as well. Moreover, the memory usage ratio of the first virtual terminal can be divided into more levels, thereby generating more flexible memory determination strategies.

[0067] For example, if the first threshold is 30% and the second threshold is 60%, and a virtual terminal has a memory usage ratio of 25%, where the size of free memory is 5G (the first weight of free memory is 80%), the size of memory used by processes is 2G (the second weight of process memory usage is 50%), and the size of memory used by file cache is 1G (the third weight of file cache memory usage is 30%), then the elastic memory in this virtual terminal can be determined to be (5G*80%+2G*50%+1G*30%) = 5.3G. It should be noted that the values ​​of the first and second thresholds are not limited. The first threshold can be 35%, 25%, or other values, and the second threshold can be 55%, 65%, or other values. However, the first threshold must be less than the second threshold to ensure the determination of the memory usage ratio.

[0068] Step S203: Determine the adjusted memory of the first virtual terminal based on the elastic memory and the initial memory.

[0069] In one possible implementation, after determining the elastic memory, the difference between the initial memory and the elastic memory can be used as the adjusted memory for the first virtual terminal. For example, if the server allocates 16GB of memory to the first virtual terminal when it is created (meaning the initial memory of the first virtual terminal is 16GB), and the elastic memory is determined to be 5.3GB, then the memory of the first virtual terminal can be adjusted to 16GB - 5.3GB = 10.7GB. It should be noted that if the elastic memory of the first virtual terminal is negative or close to zero, certain memory resources can be added to the first virtual terminal to ensure a good user experience.

[0070] In another possible implementation, the server can determine the fluctuation coefficient β based on the elastic memory, initial memory, and memory reservation buffer. The memory reservation buffer can be used to meet the user's memory needs for a future period; that is, with the memory reservation buffer, even if the user opens other files, there will be no lag or other issues. The memory reservation buffer can be used to cache other file pages. If the memory reservation buffer is represented as m, the elastic memory as Mi_qos, and the initial memory as Mi, then the fluctuation coefficient β can be determined as (Mi_qos - m) / Mi. After determining the fluctuation coefficient of the first virtual terminal, the fluctuation coefficient can be sent to the cloud platform's memory elasticity service, which can adjust the memory of the first virtual terminal based on the fluctuation coefficient.

[0071] The influence of elastic memory and initial memory factors is considered to make the determined amount of memory elasticity more reasonable. This makes it easier to appropriately extract memory resources from the target virtual machine in the future, while ensuring that the memory service quality of the target virtual machine running in the future (e.g., memory elasticity rate up to X GiB / s, CPU computing power consumption not exceeding η, and no lag for users) does not decrease, and also maximizes the utilization of memory resources.

[0072] It should be noted that, Figure 2 This example uses a single virtual machine for illustration. In cases where multiple virtual machines exist, the following can be referenced: Figure 2 The method shown applies memory adjustments to multiple virtual machines simultaneously to improve memory utilization for each virtual machine and prevent resource waste.

[0073] Figure 3 This application provides a specific virtual terminal structure diagram, as shown in the embodiment of the present application. Figure 3 As shown, the server allocates an initial 8GB of memory to the virtual terminal, and the virtual terminal has already used 4GB of memory. Inside the virtual terminal, a front-end driver runs, which can acquire memory statistics of the virtual terminal and send them to the corresponding components in the server. The memory statistics include the size of multiple types of memory space. In the server, a back-end device runs, which can execute a memory adjustment method provided in this embodiment. The back-end device receives the memory statistics sent by the front-end driver and determines the elastic memory of the virtual terminal based on the size of multiple types of memory space included in the acquired memory statistics. Based on the elastic memory and the initial memory, it determines the adjusted memory of the first virtual terminal. Through the cooperation of the front-end driver and the back-end device, the memory adjustment method provided in this embodiment can be applied to the server.

[0074] It should be noted that, Figure 3 This example uses a single virtual machine for illustration. In cases where multiple virtual machines exist, the following can be referenced: Figure 3 At the same time, the structure diagrams of multiple virtual machines are determined.

[0075] In one specific implementation, the flow of a memory adjustment method provided in this application embodiment can be as follows: Figure 4 As shown, it includes the following steps:

[0076] Step S401: At set intervals, send an information acquisition instruction to the first virtual terminal through the information acquisition process.

[0077] Step S402: Receive memory statistics information sent by the first virtual terminal.

[0078] Step S403: Based on the memory statistics of the first virtual terminal, determine the memory usage ratio between the memory already occupied in the first virtual terminal and the initial memory. If the memory usage ratio is less than or equal to a first threshold, proceed to step S404; if the memory usage ratio is greater than the first threshold but less than a second threshold, proceed to step S405; if the memory usage ratio is greater than or equal to the second threshold, proceed to step S406.

[0079] Step S404: Determine the elastic memory based on the size of free memory, process memory usage, and file cache memory usage. After executing step S404, proceed to step S407.

[0080] Step S405: Determine the elastic memory based on the amount of free memory and the amount of memory used by processes. After executing step S405, proceed to step S407.

[0081] Step S406: Determine the elastic memory based on the size of the free memory.

[0082] Step S407: The difference between the initial memory and the elastic memory is used as the adjusted memory for the first virtual terminal.

[0083] Based on the same inventive concept, this application also provides a memory adjustment device that can be applied in servers, such as... Figure 5 As shown, the memory adjustment device 500 may include:

[0086] The differential memory adjustment unit 503 is used to adjust the memory of the first virtual terminal to the difference between the initial memory and the elastic memory; the initial memory is configured by the server for the first virtual terminal when the first virtual terminal is created.

[0087] In one possible implementation, the elastic memory determination unit 502 is specifically used to determine the memory usage ratio between the memory already occupied in the first virtual terminal and the initial memory based on the memory statistics information of the first virtual terminal.

[0088] The elastic memory of the first virtual terminal is determined based on the memory usage ratio.

[0090] If the memory usage ratio is greater than the first threshold and less than the second threshold, then the elastic memory is determined based on the size of the free memory and the memory occupied by the process.

[0091] If the memory usage ratio is greater than or equal to the second threshold, then the elastic memory is determined based on the size of the free memory.

[0092] In one possible implementation, the elastic memory determination unit 502 is specifically used to multiply the size of the free memory by a first weight to obtain a first product;

[0093] Multiply the memory size occupied by the process by the second weight to obtain the second product;

[0094] Multiply the memory size occupied by the file cache by the third weight to obtain the third product;

[0095] The sum of the first product, the second product, and the third product is used as the elastic memory of the first virtual terminal.

Figure 6 The connections between other components are indicated by thick lines and are for illustrative purposes only, not as limiting information. The 600 bus can be divided into address bus, data bus, control bus, etc., for ease of representation.
