Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a control method, device, equipment and system for an application example. Background Art

[0002] The serverless platform is the latest emerging business software platform. In Serverless, application developers no longer need to pay attention to server-related matters, such as server selection, application operating environment configuration, load balancing, log collection, system monitoring, etc. These matters can all be handed over to the Serverless platform. The only thing application developers need to do is to write application code and implement business logic.

[0003] Typically, a cloud service consumer device (Cloud Service Consumer, CSC) can send a network request for an application to the cloud platform, and the cloud platform can respond to the network request through the application instance of the application to provide services to the cloud server consumer device. In addition, the cloud platform can increase the number of application instances when the network requests of the application increase, and can reduce the number of application instances when the network requests of the application decrease, thereby realizing automatic expansion and contraction of application instances. In addition, when no network requests for the application are received for a period of time, the cloud platform will release all application instances of the application in order to reduce costs.

[0004] However, in the above method, after all application instances of the application are released, when a network request of the application is received, the application instance needs to be re-created, thereby resulting in a problem of slow response to the network request.

[0013] In a third aspect, an embodiment of the present application provides a control device of an application example, including:

[0014] A determination module, used for determining that all application instances of a target application need to be released, wherein the current application instance of the target application is a first application instance;

[0015] A control module is used to create a second application instance of the target application, control the second application instance to respond to the network request of the target application, and release the first application instance, wherein the resource specification of the second application instance is different from the resource specification of the first application instance.

[0016] In a fourth aspect, an embodiment of the present application provides a control device of an application example, including:

[0017] A generation module, used to generate a network request for the target application when the cloud platform needs to provide services for the target application;

[0018] A sending module, used for sending the network request of the target application to the cloud platform;

[0019] Among them, the sending of the target application network request can trigger the cloud platform to determine that all application instances of the target application need to be released, and the current application instance of the target application is the first application instance, so that the cloud platform controls the creation of a second application instance of the target application and releases the first application instance to control the second application instance to respond to the network request of the target application, and the resource specifications of the second application instance are different from the resource specifications of the first application instance.

[0020] In a fifth aspect, an embodiment of the present application provides a control device of an application example, comprising: a memory, a processor; wherein the memory is used to store one or more computer instructions, wherein the one or more computer instructions, when executed by the processor, implement the method described in any one of the first aspects above.

In addition, since the resource specification of the second application instance is different from the resource specification of the first application instance, compared with the first application instance with the minimum number of reserved ones, the flexibility of the application instance for waiting to respond to the network request can be improved.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "said", and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two, but does not exclude the inclusion of at least one.

[0041] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0042] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0043] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0044] In addition, the step sequence in the following method embodiments is only an example and not a strict limitation.

[0045] The control method of the application example provided in the embodiment of the present application can be applied to Figure 1 In the application scenario shown, Figure 1 As shown, the application scenario may include a cloud platform 11 implemented based on serverless and a cloud service consumption device 12, and the cloud platform 11 and the cloud service consumption device 12 are connected via network communication.

[0046] Among them, the cloud service consumption device 12 can be a user of the cloud platform 11 and needs to use the cloud platform 11 to provide services for it. A cloud service consumption device 12 can use the services of one or more applications provided by the cloud platform 11. When the cloud service consumption device 12 uses the service of an application provided by the cloud platform 11, the cloud service consumption device 12 can send a network request of the application to the cloud platform 11 according to demand. After receiving the network request of the application, the cloud platform 11 can respond to the network request through the application instance of the application, thereby enabling the cloud platform 11 to provide the service of the application to the cloud service consumption device. It should be noted that this application does not limit the specific type of network request, for example, it can be a data storage request, an identity authentication request, etc.

[0047] like Figure 2 As shown, the cloud platform 11 may include a request forwarding device 11A and an application instance control device 11B. The request forwarding device 11A is used to receive a network request sent by the cloud service consumption device 12 through the network, determine the application corresponding to the network request, and forward the network request to the application instance of the corresponding application for response. The application instance control device 11B is used to control the creation and release of the application instance. Specifically, the application instance control device can control the increase in the number of application instances when the network requests of the application increase, and can control the decrease in the number of application instances when the network requests of the application decrease. The request forwarding device can be, for example, a gateway, and the application instance control device can be included in the host machine where the application instance is located, or can be included in other devices other than the host machine where the application instance is located.

[0048] It should be noted that, for the sake of distinction, in the embodiments of the present application, Figure 2 The application instance in the normal scaling scenario shown in is called the first application instance. It is understandable that there can be multiple first application instances of an application, and the multiple first application instances are completely identical, specifically, have the same functions, and have the same instance specifications, for example, the instance specifications are all 2 processor cores (core) + 4g memory.

[0049] It should be noted that Figure 2 In the example, the number of applications is 2. It can be understood that the number of applications can be greater than 2.

[0050] Usually, when the cloud platform 11 determines that it has not received a network request for an application for a period of time, in order to reduce costs, the cloud platform 11 will release all application instances of the application. Later, when the cloud platform 12 receives a network request for the application, it needs to recreate the application instance of the application in order to respond to the network request of the application and provide services to the cloud service consumer device 12. However, since it takes a certain amount of time from creating an application instance to the application instance being able to respond to a network request, there is a certain delay in processing the network request, so there is a problem of slow response to network requests. Figure 2 Based on the above, when no network request of application 1 is received for a period of time, the cloud platform 11 releases all implementations of the application. The result can be as follows: Figure 3A shown.

[0051] Alternatively, in order to solve the problem of slow response to network requests, when the cloud platform 11 determines that it has not received a network request for an application for a period of time, it does not release all application instances of the application, but retains a minimum number of application instances so that when the cloud platform receives a network request for the application again, it can respond in time. However, this method has the problem of high cost. Figure 2 Based on the above, when no network request of application 2 is received for a period of time, the cloud platform 11 retains one application instance of application 2. Figure 3B shown.

[0052] The control method for application instances provided in the embodiments of the present application determines that all application instances of the target application need to be released, the current application instance of the target application is the first application instance, controls the creation of a second application instance of the target application and releases the first application instance, so as to control the second application instance to respond to the network request of the target application. The resource specifications of the second application instance are different from those of the first application instance. When it is determined that all application instances of the target application need to be released, a second application instance with different resource specifications can be created to wait for the network request of the response application, thereby enabling timely response to the application network request. Moreover, since the resource specifications of the second application instance are different from those of the first application instance, the flexibility of the application instance waiting for the response network request can be improved. Figure 2 Based on the above, when no network request of application 2 is received for a period of time, the cloud platform 11 releases all application instances of application 2 and creates a second application instance. Figure 3C shown.

[0053] It should be noted that Figure 2-3C The medium-thin solid line represents the data surface, and the thick solid line represents the control surface.

[0054] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0055] Figure 4 This is a flow chart of a control method for an application example provided by an embodiment of the present application. The execution subject of this embodiment may be Figure 1 The cloud platform 11 in the embodiment may be specifically executed by the control device of the application instance in the cloud platform 11. Figure 4 As shown, the method of this embodiment may include:

[0056] Step 401: determine that all application instances of a target application need to be released, wherein the current application instance of the target application is a first application instance.

[0057] In this step, the specific algorithm for determining whether it is necessary to release all application instances of the target application can be flexibly implemented. Exemplarily, step 401 may specifically include: determining whether a network request for the target application is received within the most recent preset time length; if a network request for the target application is not received within the most recent preset time length, determining that all application instances of the target application need to be released. Further, if a network request for the target application is received within the most recent preset time length, determining that all embodiments of the target application do not need to be released. For example, when the number of network requests for the target application received within the most recent 1 minute is 0, it can be determined that all application instances of the target application need to be released. When the number of network requests for the target application received within the most recent 1 minute is greater than 0, it can be determined that all application instances of the target application do not need to be released.

[0058] Assuming that when it is determined that all application instances of the target application need to be released, the target application currently has three application instances, then the three application instances can be understood as the first application instance of the target application, which is different from the second application instance described below.

[0059] It should be noted that the embodiment of the present application is directed to the specific processing when it is determined that all application instances of the target application need to be released. When it is determined that all application instances of the target application do not need to be released, step 402 does not need to be performed and the process can be terminated.

[0060] Step 402, controlling the creation of a second application instance of the target application and releasing the first application instance to control the second application instance to respond to a network request of the target application, wherein the resource specification of the second application instance is different from the resource specification of the first application instance.

[0061] In this step, there may be no order restriction between controlling the release of the first application instance of the application and controlling the creation of the second application instance of the application. By controlling the creation of the second application instance first and controlling the release of the first application instance later, it is beneficial to achieve timely response to network requests to the greatest extent. By controlling the release of the first application instance first and controlling the creation of the second application instance later, it is beneficial to complete the recovery of resources deployed in the first application instance as soon as possible.

[0062] It should be noted that controlling the second application instance to respond to the network request of the application can be executed by the control device that provides the application instance, or can be executed by other devices or equipment other than the control device of the application instance, and this application does not limit this.

[0063] The specific manner in which the resource specification of the second application instance is different from the resource specification of the first application instance can be flexibly implemented according to demand. The resource specification of the application instance can refer to the amount of resources that the application instance needs to use. Among them, the resources can be, for example, software resources such as memory and processor cores, or, for example, hardware resources such as processor chips, or, for example, electrical energy resources, etc.

[0064] In this embodiment, by controlling the release of the current application instance of the target application (i.e., the first application instance) when it is determined that all application instances of the target application need to be released, and controlling the creation of a second application instance of the target application with a resource specification different from that of the first application instance, the resource specification of the second application instance is different from that of the first application instance, so that when it is determined that all implementations of the target application need to be released, a second application instance with a different resource specification is created to respond to the network request of the target application, so that when the network request of the target application is received again, the second application instance can directly respond to the network request, avoiding the problem of slow response to the network request caused by re-creating the application instance when the network request of the target application is received, shortening the response time of the network request, and realizing timely response to the network request. In addition, since the resource specification of the second application instance is different from that of the first application instance, compared with retaining the minimum number of first application instances, the flexibility of the application instance used to wait for the response to the network request can be improved.

[0065] In the above Figure 4 On the basis of the illustrated embodiment, illustratively, the resource specifications of the second application instance are different from the resource specifications of the first application instance, including one or more of the following: the instance specifications of the second application instance are lower than the instance specifications of the first application instance, the power of the processor chip for deploying the second application instance is lower than the power of the processor chip for deploying the first application instance, or the resources for deploying the first application instance are exclusive resources that do not need to be preempted with other application instances and the resources for deploying the second application instance are oversold resources that need to be preempted with other application instances. Based on this, it is possible to achieve that the resource specifications of the second application instance are lower than the resource specifications of the first application instance, which is beneficial to saving the cost of the cloud platform compared to retaining a minimum number of first application instances in the related art.

[0066] Exemplarily, the instance specifications may include the number of processor cores, memory size, etc. For example, the instance specification of the first application instance may be 2 processor cores + 4 GB memory, and the instance specification of the second application instance may be 0.5 processor cores + 4 GB memory. For example, the instance specification of the first application instance may be 2 processor cores + 4 GB memory, and the instance specification of the second application instance may be 1 processor core + 2 GB memory.

[0067] The specific method of making the instance specification of the second application instance lower than that of the first application instance can be implemented flexibly. By making the number of processor cores of the second application instance lower than that of the first application instance, the processor core resources can be reduced. By making the memory size of the second application instance lower than that of the first application instance, the memory resources can be reduced.

[0068] The method for determining the instance specifications of the second application instance can be implemented flexibly. Exemplarily, the instance specifications of the second application instance can be set by the user, or the instance specifications of the second application instance can be automatically determined by the cloud platform based on the instance specifications of the first application instance in accordance with a preset downgrading strategy. The instance specifications of the second application instance are automatically determined by the control device of the application instance according to the instance specifications of the first application instance and the preset downgrading strategy, which is conducive to improving the flexibility of the cloud platform in determining the instance specifications of the second application instance. Among them, the downgrading strategy can, for example, reduce the number of processor cores, or reduce the processor cores by a few percent. It should be noted that this application does not limit the method for determining the instance specifications of the first application instance, for example, it can be configured by the user.

[0069] Since the power of processor chips is different, the power consumption of processor chips will be different. Therefore, by deploying the processor chip of the second application instance with a power lower than the power of deploying the processor chip of the first application instance, it is possible to deploy the second application instances on processor chips with lower power, which is beneficial to saving power consumption and thus reducing costs.

[0070] Exemplarily, the instruction systems of the first application instance and the second application instance are different. By having the instruction system of the second application instance be different from the instruction system of the first application instance, the scope of selecting a processor chip with lower power for the second application instance can be expanded, which is conducive to improving the flexibility of hardware implementation of deploying the first application instance and the second application instance on processing chips with different power. Among them, the instruction system of the first application instance can be, for example, an Intel instruction set, and the instruction system of the second application instance can be, for example, an Advanced RISC Machine (ARM) instruction set, so that unlike deploying the processor chip of the first application instance as an Intel chip, deploying the second application instance can select an ARM chip.

[0071] It should be noted that, in a scenario where the resources of the first application instance are exclusive resources and the resources of the second application instance are oversold resources, the instance specifications of the second application instance may be the same as those of the first application instance.

[0072] Among them, the resources for deploying application instances are exclusive resources and are explained as follows: assuming that the resources of application instance a are exclusive resources, the instance specification of application instance a is 2 processor cores, and the number of processor cores of a server is 32, then the server can deploy a maximum of 16 application instances a, each application instance a exclusively uses 2 processor cores, and the 16 application instances a do not compete for resources with each other.

[0073] During the actual operation of application instances, the resource usage of application instances often does not reach the number of resources agreed upon in their instance specifications, resulting in resource waste. In order to improve resource utilization, the concept of overselling is introduced, that is, the sum of the resources agreed upon in the instance specifications of all application instances on the server exceeds the amount of resources owned by the server itself. In the process of overselling, different application instances will compete for resources, which is also caused by the nature of overselling. The maximum resources that an application instance can occupy are the number of resources agreed upon in its instance specifications.

[0074] Among them, the resource for deploying application instances is oversold resource as explained below: assuming that the resource of application instance b is oversold resource, the instance specification of application instance b is 2 processor cores, and the number of processor cores of a server is 32, then the server can deploy more than 16 application instances b at most, for example, 32 application instances b can be deployed, the 32 application instances b compete for resources with each other, and one application instance b can occupy 2 processor cores at most.

[0075] It can be seen that the resources of the second application instance are oversold resources, which can improve resource utilization compared to the first application instance, which is an exclusive resource, thereby reducing the resource specifications of the application instance.

[0076] In the above Figure 4 Based on the illustrated embodiment, illustratively, the controlling the creation of the second application instance of the target application may specifically include: allocating resources to the second application instance of the target application, and controlling the running of the second application instance in the resources allocated to the second application instance. Specifically, the resources allocated to the second application instance may be selected from the resource pool according to the resource allocation information of the second application instance, and the resource allocation information includes relevant information for allocating resources to the second application instance, such as the instance specification of the second application instance, the processor chip of the second application instance, etc.

[0077] In the above Figure 4 On the basis of the illustrated embodiment, illustratively, the controlling the second application instance to respond to the network request of the target application may specifically include: when determining that the second application instance can process the network request of the target application, adding the second application instance to the instance list of the target application, so that the request forwarding device can forward the network request of the target application to the second application instance according to the instance list. The instance list of the target application is used to request the forwarding device to forward the received network request of the target application, so that the application instance of the target application can receive the network request of the target application and respond. It is understandable that when the first application instance is released, the first application instance can be deleted from the instance list of the target application.

[0078] In the above Figure 4 Based on the illustrated embodiment, illustratively, the number of the second application instance is 1. By setting the number of the second application instance to 1, the cost can be reduced to the greatest extent.

[0079] Figure 5 This is a flow chart of a control method for an application instance provided by another embodiment of the present application. Based on the above embodiment, this embodiment mainly describes an optional implementation method after releasing the first application instance and creating the second application instance. Figure 5 As shown, the method of this embodiment may include:

[0080] Step 501: determine that all application instances of a target application need to be released, wherein the current application instance of the target application is a first application instance.

[0081] It should be noted that step 501 is similar to step 401 and will not be described in detail here.

[0082] Step 502, controlling the creation of a second application instance of the target application and releasing the first application instance to control the second application instance to respond to a network request of the target application, wherein the resource specification of the second application instance is different from the resource specification of the first application instance.

[0083] It should be noted that step 502 is similar to step 402 and will not be described in detail here.

[0084] Step 503, determining whether a preset condition is met.

[0085] In this step, the resource specifications of the second application instance are different from those of the first application instance, and its processing capacity is different from that of the first application instance. In order to ensure that the processing capacity of the application instance of the target application can meet the demand as much as possible, it can be indicated that the first application instance needs to be recreated when the preset conditions are met. If the preset conditions are not met, it means that the first application instance does not need to be recreated.

[0086] Among them, the preset condition is used to predict whether there will be a large number of network requests of the target application that need to be responded to in the future. If the preset condition is met, it can be characterized by the prediction that a large number of network requests of the target application will need to be responded to in the future; if the preset condition is not met, it can be characterized by the prediction that there will not be a large number of network requests of the target application that need to be responded to in the future. The preset condition can be flexibly implemented according to specific needs. Exemplarily, the preset condition may include any one of the following: receiving a network request of the target application, the number of network requests of the target application received is greater than the number threshold, the network request of the target application is received and the time from the receiving time is greater than the time threshold, or the load of the second application instance is greater than the load threshold, etc.

[0087] Step 504: If the preset condition is met, control the creation of the first application instance to control the first application instance to respond to the network request of the target application.

[0088] It should be noted that the specific method of controlling the creation of the first application instance and controlling the first application instance to respond to the network request is similar to the specific method of controlling the creation of the second application instance and controlling the second application instance to respond to the network request, and will not be repeated here.

[0089] Optionally, after step 504, the method may further include: when the first application instance is able to respond to the network request of the target application, controlling the second application instance to no longer respond to the network request of the target application. Exemplarily, the second application instance may be deleted from the instance list so that the second application instance no longer responds to the network request of the target application. It should be noted that the second application instance may continue to respond to the network request that the second application instance is responding to until the response is completed.

[0090] By controlling the second application instance to no longer respond to the network request of the target application, the first application instance is used to respond to the network request of the target application in normal expansion and contraction scenarios. Since the processing capability of the second application instance is different from that of the first application instance, by controlling the second application instance to no longer respond to the network request when the first application instance can respond to the network request, the special scenario where application instances with different processing capabilities respond to the network request can be avoided, thereby avoiding special implementation for the special scenario, which is conducive to simplifying the implementation.

[0091] Exemplarily, controlling the second application instance to no longer respond to the network request of the target application may specifically include: controlling the release of the second application instance. By controlling the release of the second application instance, resources used to deploy the second application instance can be recycled, which is conducive to improving resource utilization.

[0092] In this embodiment, by determining whether a preset condition is met, if the preset condition is met, the creation of the first application instance is controlled to control the first application instance to respond to the network request of the target application. This achieves that, on the basis of the second application instance being able to respond to the network request of the target application, when it is predicted that a large number of network requests of the target application will need to be responded to, the first application instance whose processing capacity can meet the demand is controlled to respond to the network request, thereby avoiding the problem of the cloud platform being unable to respond to network requests in a timely manner due to the limited processing capacity of the second application instance and the large number of network requests.

[0093] Specifically, the specific process of the cloud platform processing network requests can be as follows: Figure 6 Reference Figure 6In a normal scaling scenario, the request forwarding device forwards the network request of the target application to the first application instance, and the first application instance responds to the network request. The control device of the application instance can automatically scale the first application instance according to demand, where a small square represents an application instance of the target application, and those numbered 1, 2, 3, 4, 5, ... are first application instances, and those not numbered are second application instances. When it is determined that all application instances of the target application need to be released, the control device of the application instance controls the release of the first application instance and controls the creation of the second application instance. The request forwarding device forwards the network request of the target application to the second application instance, and the second application instance responds to the network request. It should be noted that Figure 6 The solid line indicates the flow direction in normal scaling scenarios, the dotted line indicates the flow direction in special scenarios of abnormal scaling, the thin solid line and the thin dotted line indicate the data plane, and the thick solid line and the thick dotted line indicate the control plane.

[0094] Figure 7 This is a flow chart of a control method of an application example provided by another embodiment of the present application. The execution subject of this embodiment may be Figure 1 The cloud service consumption device 12 in the embodiment. Figure 7 As shown, the method of this embodiment may include:

[0095] Step 701, generating a network request for the target application when the cloud platform is required to provide services for the target application;

[0096] Step 702, sending the network request of the target application to the cloud platform;

[0097] Among them, the sending of the target application network request can trigger the cloud platform to determine that all application instances of the target application need to be released, and the current application instance of the target application is the first application instance, so that the cloud platform controls the creation of a second application instance of the target application and releases the first application instance to control the second application instance to respond to the network request of the target application, and the resource specifications of the second application instance are different from the resource specifications of the first application instance.

[0098] It should be noted that for the specific method of the cloud platform determining that all application instances of the target application need to be released, and controlling the creation of the second application instance of the target application and releasing the first application instance, please refer to the relevant description of the aforementioned embodiment, which will not be repeated here.

[0099] In this embodiment, when the cloud platform is required to provide services for the target application, the cloud service consumption device generates a network request for the target application and sends the network request for the target application to the cloud platform; wherein the sending of the network request for the target application can trigger the cloud platform to determine that all application instances of the target application need to be released, so that the cloud platform can control the release of the current application instance of the target application (i.e., the first application instance) and control the creation of a second application instance with different resource specifications from the first application instance when it is determined that all application instances of the target application are released, so as to control the second application instance to respond to the network request of the target application, so that when the network request of the target application is received again, the second application instance can directly respond to the network request, thereby avoiding the problem of slow response to the network request caused by re-creating the application instance when the network request of the target application is received, shortening the response time of the network request, and achieving timely response to the network request.
