Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Please refer to fig. 1, which shows a schematic diagram of a resource allocation system according to a resource allocation method provided in some embodiments of the present application. The resource allocation system may include: at least one terminal 110, a DNS server 120, at least one proxy server 130, at least one application server 140, at least one cache server 150, and at least one database server 160. Each proxy server establishes a connection relationship with at least one of the cache server, the database server, and the application server.

The DNS server 120, the proxy server 130, the application server 140, the cache server 150, and the database server 160 may be a single server, or a server cluster composed of several servers, or a cloud computing service center. The terminal 110 may be a smartphone, a computer, a multimedia player, an e-reader, a wearable device, etc.

The connection between the terminal 110 and the DNS server 120 may be established through a wired network or a wireless network, the connection between the DNS server 120 and the proxy server 130 may be established through a wired network or a wireless network, and the connection between the proxy server 130 and at least one of the application server 140, the cache server 150, and the database server 160 may be established through a wired network or a wireless network.

In another implementation environment, the DNS server 120 and the proxy server 130 may be replaced by load balancers, that is, the load balancers may implement the functions of the DNS server 120 and the proxy server 130. Each load balancer is connected with at least one of the application server, the cache server and the database server.

In the related art, the proxy server is configured to receive a service request sent by the terminal through the DNS server, where the service request may indicate an internet service to be processed, and the application server is configured to process the internet service by using a plurality of services. Each of the plurality of services is for performing an operation. After the application server completes the processing of the internet service by adopting a plurality of services, the resources occupied by the services are released, so that the total time for the resources occupied by the services is longer, and the resource utilization rate is lower.

For example, the internet service is an online shopping service, when the online shopping service is processed, a user needs to log in to a corresponding shopping website through a terminal, in the process, a service request received by the terminal is a login request, the login request is used for indicating the online shopping service to be processed, a proxy server receives the login request sent by the terminal through a DNS server, and an application server processes the online shopping service by adopting a login service, a verification service and an authority service, wherein the login service, the verification service and the authority service are all application programs. In the process, a user needs to input a user name, a password and a check code on a login page of a terminal and click a login button, the terminal sends a login request to a DNS (domain name server) after receiving a login instruction triggered by the user, the DNS sends the login request to a proxy server, the proxy server sends the login request to a corresponding application server, the login request carries the user name, the password and the check code, and the application server verifies the user name, the password and the check code after receiving the login request sent by the proxy server. The application server adopts the login service to execute the verification operation on the user name and the password, adopts the verification service to execute the verification operation on the verification code, and adopts the authority service to execute the authority acquisition operation.

However, after the application server completes the processing of the online shopping service by using the login service, the verification service and the permission service, the resources occupied by the login service, the verification service and the permission service are released, so that the total time for the login service, the verification service and the permission service to occupy the resources is longer, and the resource utilization rate is low.

The embodiment of the application provides a resource allocation method, which can be used for an application server of a resource allocation system. The resource allocation system further includes a target device, which may include a proxy server or may include a load balancer, as shown in fig. 2, and the method includes:

step 101, receiving a service indication message sent by a target device, where the service indication message carries a first service request, and the first service request is used to indicate a first service to be processed.

Step 102, in the process of processing the first service by adopting a plurality of services, releasing the resources occupied by at least one service which has executed the operation corresponding to the first service.

To sum up, in the resource allocation method provided in this embodiment of the present application, the application server receives the service indication message sent by the target device, and in the process of processing the first service by using multiple services, the resource occupied by at least one service that has executed the operation corresponding to the first service may be released, and the resource may be reused. The application server releases the resources occupied by at least one service which has executed the operation corresponding to the first service in the process of processing the first service, so that the resources do not need to be released after all the operations are executed, the available resources are released in advance, and the resource utilization rate is improved.

For example, when processing online shopping service, the application server receives a service indication message sent by the proxy server, where the service indication message carries a login request, and the login request is used to indicate the online shopping service to be processed. The application server can release the resources occupied by the login service which has executed the verification operation of the user name and the password in the process of processing the online shopping service by adopting the login service, the verification service and the authority service, the resources can be utilized again, and the application server does not need to release the resources after the verification operation of the user name and the password, the verification operation of the verification code and the authority acquisition operation are executed, so that the early release of the available resources is realized, and the resource utilization rate is improved.

The embodiment of the application provides a resource allocation method, which is used for a target device of a resource allocation system, wherein the target device may include a proxy server or a load balancer. As shown in fig. 3, the method includes:

step 201, receiving a first service request, where the first service request is used to indicate a first service to be processed.

Step 202, sending a service indication message to the application server, where the service indication message carries the first service request, and the service indication message is used to indicate the application server to release resources occupied by at least one service that has executed the operation corresponding to the first service in the process of processing the first service by using multiple services.

To sum up, in the resource allocation method provided in this embodiment of the present application, after receiving the first service request, the proxy server sends a service indication message to the application server, where the service indication message is used to indicate that, in a process of processing the first service by using multiple services, the application server can release a resource occupied by at least one service that has performed the operation corresponding to the first service, and the resource can be reused.

The target device in the resource allocation system related to the resource allocation method provided by the embodiment of the present application may include a proxy server, or may include a load balancer. In the following embodiments, the target device includes a proxy server as an example to describe the resource allocation method, and when the target device includes a load balancer, the resource allocation method performed by the load balancer is the same as the resource allocation method performed by the proxy server, and therefore, this is not described again in this embodiment. As shown in fig. 4, the resource allocation method may include:

step 301, the proxy server receives a first service request.

The first service request is used for indicating a first service to be processed.

In the embodiment of the application, after receiving a first service request, a terminal sends the first service request to a DNS server, where the first service request carries domain name information of the terminal, and the DNS server is configured to obtain an Internet Protocol (IP) address of a corresponding proxy server from a preset corresponding relationship according to the domain name information of the terminal, and send the first service request to the proxy server indicated by the IP address, where the preset corresponding relationship stores a corresponding relationship between the domain name information of the terminal and the IP address of the proxy server.

Table 1 exemplarily shows the correspondence between the domain name information of 2 terminals and the IP addresses of 2 proxy servers, referring to table 1, when the domain name information of a terminal is aa.com, the IP address of the corresponding proxy server is 10.15.36.18; cn, when the domain name information of the terminal is abc, the IP address of the corresponding proxy server is 10.15.36.19.

TABLE 1

Domain name information of terminal	IP address of proxy server
		aa.com	10.15.36.18
abc.cn	10.15.36.19

Step 302, the proxy server sends a service indication message to the application server.

The service indication message carries a first service request.

Correspondingly, the application server receives a service indication message sent by the proxy server, wherein the service indication message carries a first service request, and the first service request is used for indicating a first service to be processed. For example, the first service request may be a login request, and the first service to be processed is an online shopping service.

In an implementation manner, the proxy server may store a corresponding relationship between the service request identifier and the application server identifier, when the proxy server receives the first service request, the first service request carries the identifier of the first service request, the proxy server queries the corresponding relationship, obtains the application server identifier corresponding to the identifier of the first service request from the corresponding relationship, and then, when step 302 is executed, the proxy server may send the service indication message to the corresponding application server according to the obtained application server identifier.

Step 303, the application server obtains the configuration file.

In this embodiment of the present application, the configuration file may be stored in a designated location of the application server in advance, and the configuration file may be acquired from the designated location before the application server starts the service.

The configuration file obtained may be multiple. Each profile is used to initiate a service. Each configuration file includes configuration information that may be generated from a tomcat application used to launch services in the related art.

Step 304, the application server starts a plurality of services through the configuration information in the configuration file.

The configuration information includes initiation information for initiating any of a plurality of services.

In the related art, a tomcat application is used to start a service. Each service corresponds to a tomcat application, which includes, in addition to the start information for starting the service, other information, such as control information and management information. Typically, the size of a tomcat application is about 200 megabits. Since the configuration information of the configuration file in the embodiment of the present application only includes the start information for starting the service, the configuration information of the configuration file is less and the storage space of the application server occupied is smaller compared with the tomcat application.

In the related art, before starting a plurality of services, a corresponding tomcat application program needs to be configured for each service. In the process of starting the service, a plurality of services need to be started by starting a plurality of tomcat applications, and since the size of each tomcat application is about more than 200 megabytes, the plurality of tomcat applications occupy a large amount of storage space of the application server, and in the process of starting the plurality of services, the plurality of tomcat applications occupy a large running memory of the application server.

The configuration file provided by the embodiment of the application only comprises the starting information for starting the service, and the configuration file is about tens of megabytes, so that the storage space occupied by the plurality of configuration files by the application server is small, and meanwhile, in the process of starting the plurality of services, the running memory occupied by the plurality of configuration files by the application server is small, so that the application server can process more services.

Step 305, the application server releases the resource occupied by at least one service that has executed the operation corresponding to the first service in the process of processing the first service by adopting a plurality of services.

In the embodiment of the application, the application server executes corresponding operation according to the indication information in the service indication message sent by the proxy server.

Optionally, the service indication message includes first indication information, which is used to indicate that, when the application server obtains the second service request in a process of processing the first service by using multiple services, the application server releases resources occupied by all services that have executed operations in the multiple services. Accordingly, step 305 may include: and the application server releases resources occupied by all services which have executed the operation in the plurality of services when acquiring the second service request in the process of processing the first service by adopting the plurality of services.

The second service request is used for indicating a second service to be processed. The second service request is sent to the application server by the proxy server through the service indication message.

For example, the first service request may be a login request, and the first service to be processed is an online shopping service. The second service request may be a query request, and the second service to be processed is a data download service.

Assuming that at least one service which has executed the operation corresponding to the first service includes the first service, the second service and the third service, in the process that the application server adopts a plurality of services to process the first service, when the application server acquires the second service request, the application server releases the resources occupied by the first service, the second service and the third service.

Optionally, the service indication message includes second indication information, which is used to indicate that, in a process of processing the first service by using multiple services, the application server releases resources occupied by the service executing the operation after each operation corresponding to one first service is completed. Accordingly, step 305 may include: in the process of processing the first service by adopting a plurality of services, the application server releases the resources occupied by the service executing the operation after finishing the corresponding operation of each first service.

Assume that the application server processes the first service with a first service, a second service, and a third service, the first service being used to perform operation a, the second service being used to perform operation B, and the third service being used to perform operation C. The application server releases the resources occupied by the first service executing the operation A after completing the operation A in the process of processing the first service by adopting the three services; after the operation B is finished, releasing resources occupied by a second service for executing the operation B; and after the operation C is finished, releasing the resources occupied by the third service for executing the operation C.

Optionally, the service indication message includes third indication information, which is used to indicate that the application server, after executing an operation using one service, indicates that the one service calls another service through the JMX interface of the Java management extension to execute another operation. Accordingly, the application server in step 305 processes the first service by using a plurality of services, including: after one operation is executed by one service, the application server indicates one service to call another service through the JMX interface for Java management extension so as to execute another operation.

For example, in the related art, after the application server performs the verification operation of the user name and the password by using the login service, the application server instructs the login service to call the permission service through a HyperText Transfer Protocol (http) to perform the permission acquisition operation, and then completes the login process based on the user name, the password, and the check code. The application server indicates that three handshakes are needed when the login service calls the http interface, so that the time for executing the authority obtaining operation is long.

In the embodiment of the application, after the login service is adopted to execute the verification operation of the user name and the password, the application server indicates the login service to call the authority service through the JMX interface to execute the authority acquisition operation, and three-way handshake is not needed in the process, so that the processing time of the online shopping service is shortened.

Optionally, the JMX interface may be configured by using an eXtensible Markup Language (xml) file. After one service is adopted to execute one operation, when one service has no authority to call another service through the Java management extension JMX interface, the application server can modify the xml file corresponding to the JMX interface so that the service has the authority to call another service through the Java management extension JMX interface.

In the related art, when the service does not have a right to call another service through the http interface, the application server needs to modify the code for implementing the service and the code for the another service at the same time, and the codes are implemented based on the http protocol, so that the codes are complex and the code modification time is long. In addition, it takes a long time to test the modified code.

In the embodiment of the application, the application server modifies the xml file corresponding to the JMX interface, so that the modification time is short, and the test time for the modified xml file is short.

Step 306, when receiving the data writing request, the proxy server sends the data writing request to the database server.

The data writing request is used for indicating the database server to store the target data, and the data writing request carries the target data.

The proxy server may establish a connection relationship with a plurality of database servers.

In this step, the proxy server may instruct the database server to store the target data through the data write request according to the storage space of each database server. In order to reduce the pressure of the database servers, after receiving the data writing request, the proxy server firstly determines the database server of which the current storage space is larger than the preset value, and sends the received data writing request to the database server of which the current storage space is larger than the preset value, so that the storage data amount of the plurality of database servers is equivalent, and the effect of load balancing is achieved.

When there are m database servers (m is an integer greater than or equal to 2) whose storage space determined by the proxy server is greater than the preset value, the proxy server may send the target data carried in the data write request to the m database servers in the following 2 ways.

In a first implementation manner, the proxy server may send the target data carried in the data write request to m database servers according to the receiving time of the data write request, so that each database server stores the corresponding target data. For example, the proxy server may send the target data carried in the data write request received on day 1 to the first database server, and send the target data carried in the data write request received on day 2 to the second database server, and so on.

In a second implementation manner, the proxy server may send the target data carried in the data write request to the m database servers according to the data type of the target data, so that each database server stores the corresponding target data.

Assuming that m is 2, the proxy server may send the target data of the entertainment class carried in the data write request to the first database server, and send the target data of the sports class carried in the data write request to the other database server.

Step 307, when receiving the data query request, the proxy server sends the data query request to the cache server.

The data query request is used for instructing the cache server to query the specified data.

Correspondingly, the cache server receives the data query request sent by the proxy server.

Because the calculation speed stored by the cache server is high, in order to quickly acquire the designated data, the proxy server sends the data query request to the cache server, and then acquires the designated data from the cache server.

Step 308, the cache server queries the specified data based on the data query request.

Step 309, when the query operation for the specified data fails to be executed, the cache server sends a data query response to the proxy server.

When the cache server does not inquire the specified data, namely the execution of the inquiry operation aiming at the specified data fails, the cache server can send a data inquiry response to the proxy server so that the proxy server sends the data inquiry request to the database server. The data query response indicates that the query operation for the specified data failed to execute.

And step 310, when receiving the data query response sent by the cache server, the proxy server sends the data query request to the database server.

Since the database server stores all the data, when the proxy server receives the data query response sent by the cache server, the data query request can be sent to the database server, so that the database server queries the specified data based on the data query request, and sends the specified data to the proxy server and the cache server, so that the specified data can be sent to the terminal by the proxy server for display. Meanwhile, the cache server stores the specified data, and the proxy server can acquire the specified data from the cache server when the specified data is queried next time.

Step 311, the cache server receives the specified data sent by the database server, and stores the received specified data to the disk.

In the related art, the cache server stores the designated data sent by the database server into the memory, when the cache server is restarted or upgraded, the data of the cache server is emptied, and the cache server needs to acquire the data from the database server again. When the amount of acquired data is large, the calculation pressure of the cache server is increased, and the cache server cannot determine which data is acquired from the database server.

In the embodiment of the present application, the cache server stores the designated data sent by the database server to the disk, so that the data in the cache server cannot be emptied even if the cache server is restarted or upgraded. Therefore, after the cache server is restarted or upgraded, the cache server does not need to acquire data from the database server, and the computing pressure of the cache server is reduced.

Step 312, the cache server determines the locally stored preset data after a preset time period as hot data, and the cache server sets an automatic expiration mechanism for the preset data.

The preset data generally does not include data with a degree of change smaller than a specified degree threshold value within a preset time period, and the hit data refers to data with a high query frequency.

For example, the preset data may be service data, and the service data may be a name of a commodity when shopping online. For example, the data that changes to a degree less than the specified degree threshold within the preset time period may be data such as a user name.

In order to ensure that the current hot data is stored in the cache server, the cache server is provided with an automatic expiration mechanism aiming at the preset data, wherein the automatic expiration mechanism means that the preset data is automatically deleted after a specified time length. For example, the specified duration may be three minutes. The preset data is deleted through the automatic expiration mechanism, the preset data is stored in the cache server next time if the preset data is hot data, and then the preset data is deleted again through the automatic expiration mechanism, so that after the preset time, if the preset data is still stored in the cache server, the preset data is necessarily the hot data. The cache server may determine data still existing after a preset time period as hot data. The preset time period may be half an hour, or 1 hour, etc.

Step 313, when the cache server receives the query instruction for the hot data, the cache server obtains the hot data.

As shown in step 312, since the cache server is provided with the automatic expiration mechanism for the preset data, after the preset duration, only the hot data is stored in the cache server, and when the cache server receives the query instruction for the hot data, only the hot data needs to be acquired from the currently stored hot data, so that the time for acquiring the hot data is reduced.

It should be noted that the order of the steps of the resource allocation method provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be increased or decreased according to the situation, for example, step 303, step 304, and step 306 are optional steps.
