Description

Technical Field

[0001] This article relates to service governance technologies, and more particularly to a service governance method and apparatus. Background Technology

[0002] In some scenarios, a large number of application services are deployed on thousands of servers. To achieve service governance, Java applications can generally use Dubbo or Spring Cloud to easily implement service governance functions. However, it is often more difficult for non-Java programs or some introduced services that do not support secondary development to achieve service governance.

[0003] In related technologies, when using Docker containers on a large scale, the sidecar pattern can be used to solve service governance problems by implementing a pattern similar to service mesh.

[0004] However, when using virtual machines as servers, this approach requires a sidecar component for each virtual machine to address service governance issues. Therefore, when using virtual machines as servers on a large scale, a large number of sidecar components need to be introduced, which greatly increases the workload of deployment and maintenance. Summary of the Invention

[0005] This application provides a service governance method and apparatus that can achieve service governance without introducing sidecar components, thereby saving deployment and maintenance workload.

[0006] On the one hand, this application provides a service governance method, including: Use the process management tool Supervisor to manage the services provided by the target system; When the state of at least one of the services managed by the supervisor is adjusted, the current state information of the target service whose state has been adjusted is sent to the pre-set event listener. The event listener is used to perform operations in the registry center that are adapted to the current state information of the target service.

[0007] On the other hand, this application provides a service governance apparatus, including: a memory and a processor, wherein the memory is used to store an executable program; The processor is used to read and execute the executable program to implement the service governance method described above.

[0008] Compared with related technologies, this application includes using a supervisor to manage the services provided by the target system; when the state of at least one target service among the services managed by the supervisor is adjusted, the current state information of the target service is sent to a pre-set event listener; the event listener is used to process the current state information of the target service in the registry center. Therefore, through the event mechanism of the supervisor, the purpose of dynamically performing corresponding operations to the registry center is achieved, and service governance is realized without introducing sidecar components, thereby saving the workload of deployment and operation and maintenance.

[0015] This application provides a service governance method, such as... Figure 1 As shown, it includes: Step 101: Use the process management tool Supervisor to manage the services provided by the target system; Step 102: When the state of at least one of the services managed by the supervisor is adjusted, the current state information of the target service whose state has been adjusted is sent to the pre-set event listener. Step 103: Use the event listener to perform operations in the registry center that are appropriate for the current state information of the target service.

[0016] Supervisor is a process management tool written in Python that can easily implement process startup, restart, and shutdown functions on Unix-like systems. However, the native Supervisor can only perform simple management of service processes and cannot directly provide the more information needed for service governance. Therefore, this embodiment of the application utilizes the event mechanism of the Supervisor process management program to set up a custom event listener, EventListener, and works in conjunction with the registry center generally used for service governance to achieve service governance through interaction.

[0017] For example, a flowchart illustrating the specific implementation of a service governance method can be shown as follows: Figure 2 As shown, assuming the supervisor manages services A, B, C, and D, when the state of service A, B, C, or D is adjusted, the supervisor sends the current state information of the target service whose state has been adjusted to a pre-set event listener, so that the event listener can perform an operation in the registry center that is adapted to the current state information of the target service.

[0018] The service governance method provided in this application uses a supervisor to manage the services provided by the target system. When the state of at least one target service managed by the supervisor is adjusted, the current state information of the target service is sent to a pre-set event listener. The event listener is used to process the service in the registry center in accordance with the current state information of the target service. Therefore, through the event mechanism of the supervisor, the purpose of dynamically performing corresponding operations to the registry center is achieved. Service governance is achieved without introducing a sidecar component, thereby saving the workload of deployment and maintenance.

[0019] In one exemplary instance, the adjustment of the state of the target service includes one of the following: the target service is adjusted from an unstarted state to a started state, the target service is adjusted from a running state to a stopped state, and the target service is adjusted from a running state to an error-reporting state.

[0020] For example, the supervisor manages the services provided by the target system. When the supervisor uses a subroutine to start a service that was not originally started, the service's state is changed from not started to started. When the supervisor uses a subroutine to stop a service that was originally running, the service's state is changed from running to stopped. When the supervisor receives a subroutine exit or uses a subroutine to detect error events such as a port being unavailable, the service's state is changed from running to error state.

[0021] In one exemplary instance, when sending the current state information of the target service whose state has been adjusted to a pre-set event listener, the method further includes: The identification information of the target service is sent to the event listener.

[0022] In one exemplary instance, the operation of utilizing the event listener in the registry center, adapted to the current state information of the target service, includes: The event listener is used to obtain the configuration information of the target service from the supervisor's configuration file based on the identification information of the target service, and the event listener is used to perform operations in the registry center that are appropriate for the current state information of the target service based on the obtained configuration information.

[0023] In one exemplary instance, the configuration information of the target service includes: the name information of the target service and the service provision information of the target service.

[0024] In one exemplary instance, the service provision information of the target service includes: the IP address of the node server on which the target service is deployed, and the port number on the node server on which the target service is deployed for providing the target service.

[0025] In one exemplary instance, when the current state of the target service is the "started" state, the step of using the event listener to perform operations in the registry center adapted to the current state information of the target service based on the obtained configuration information includes: First, the event listener is used to search for the registration information of the target service in the registry center based on the name information of the target service; When the registration information of the target service is found, the registration information of the target service is updated according to the service provision information of the target service. If no registration information for the target service is found, the registration information for the target service is created based on the name information and service provision information of the target service.

[0026] For example, if the registration information of the target service is found in the registry, it means that the target service has already been registered in the registry and a node server is already providing the target service. Therefore, the service provision information of the target service is the IP address and port number information of the other node servers providing the target service. It is only necessary to add the IP address and port number information of the new node server providing the target service to the registration information field of the target service in the registry. Conversely, if the registration information of the target service is not found in the registry, it means that the target service has not been registered in the registry and no node server has previously provided the target service. Therefore, it is necessary to register the name information of the target service along with the IP address and port number information of the node server providing the target service in the registry.

[0027] In one exemplary instance, when the current state of the target service is the stopped state or the error state, the step of using the event listener to perform an operation in the registry center adapted to the current state information of the target service based on the obtained configuration information includes: First, the event listener is used to search for the registration information of the target service in the registry center based on the name information of the target service; Secondly, the parts of the registration information of the target service that are identical to the service provision information of the target service are removed.

[0028] In one exemplary instance, prior to managing the services provided by the target system using a supervisor, the process further includes: For each service provided by the target system, the startup command and parameters for that service are configured in the supervisor's configuration file.

[0029] In one exemplary instance, the method further includes: First, obtain the registration information query request from the service requester; Secondly, the registration information corresponding to the registration information query request is obtained from the registration center, and the obtained registration information is returned to the service requester.

[0030] For example, the service requester (i.e. the service user) can implement the corresponding client according to actual needs, which can achieve both high availability and decoupling from the server.

[0031] This application also provides a service governance device, such as... Figure 3 As shown, it includes: a memory 31 and a processor 32, wherein the memory 31 is used to store executable programs; The processor 32 is used to read and execute the executable program to perform the following steps: Use the process management tool Supervisor to manage the services provided by the target system; When the state of at least one of the services managed by the supervisor is adjusted, the current state information of the target service whose state has been adjusted is sent to the pre-set event listener. The event listener is used to perform operations in the registry center that are adapted to the current state information of the target service.

[0032] In one exemplary instance, the adjustment of the state of the target service includes one of the following: the target service is adjusted from an unstarted state to a started state, the target service is adjusted from a running state to a stopped state, and the target service is adjusted from a running state to an error-reporting state.

[0033] In one exemplary instance, when the current state information of the target service whose state has been adjusted is sent to a pre-set event listener, the processor 32 is used to read and execute the executable program to achieve the following steps: The identification information of the target service is sent to the event listener.

[0034] In one exemplary instance, the processor 32 is configured to read and execute the executable program to perform the following steps: The event listener is used to obtain the configuration information of the target service from the supervisor's configuration file based on the identification information of the target service, and the event listener is used to perform operations in the registry center that are appropriate for the current state information of the target service based on the obtained configuration information.

[0035] In one exemplary instance, the configuration information of the target service includes: the name information of the target service and the service provision information of the target service.

[0036] In one exemplary instance, when the current state of the target service is the startup state, the processor 32 is configured to read and execute the executable program to perform the following steps: The event listener is used to search for the registration information of the target service in the registry center based on the name information of the target service. When the registration information of the target service is found, the registration information of the target service is updated according to the service provision information of the target service. If no registration information for the target service is found, the registration information for the target service is created based on the name information and service provision information of the target service.

[0037] In one exemplary instance, when the current state of the target service is the stopped state or the error state, the processor 32 is used to read and execute the executable program to achieve the following steps: The event listener is used to search for the registration information of the target service in the registry center based on the name information of the target service. Remove the portion of the registration information of the target service that is identical to the service provision information of the target service.

[0038] In one exemplary instance, the processor 32 is configured to read and execute the executable program to perform the following steps: For each service provided by the target system, the startup command and parameters for that service are configured in the supervisor's configuration file.

[0039] In one exemplary instance, the processor 32 is configured to read and execute the executable program to perform the following steps: Obtain the registration information query request from the service requester; The system retrieves the registration information corresponding to the registration information query request from the registration center and returns the obtained registration information to the service requester.

[0040] In one exemplary instance, the service provision information of the target service includes: the IP address of the node server on which the target service is deployed, and the port number on the node server on which the target service is deployed for providing the target service.

[0041] The service governance device provided in this application embodiment utilizes a supervisor to manage services provided by a target system. When the state of at least one target service managed by the supervisor is adjusted, the current state information of the target service is sent to a pre-set event listener. The event listener is used to process the current state information of the target service in the registry center. Therefore, through the event mechanism of the supervisor, the purpose of dynamically performing corresponding operations to the registry center is achieved. Service governance is realized without introducing a sidecar component, thereby saving the workload of deployment and maintenance.
