Detailed Description

The embodiment of the application provides a method, equipment and a system for service offline based on a micro-service architecture, which effectively improve the updating efficiency and performance of an application system, effectively avoid the loss of external data requests and reduce the calling failure of the external data requests.

Referring to fig. 2, a schematic diagram of a service offline system based on a microservice architecture provided in the embodiment of the present application is shown. The service offline system includes a service control device 800, a service registration device 1000, a Gateway device Gateway1200, each service node 101, 102, 201, 202, 301, 302, and the like.

It should be noted that, in the micro service architecture provided in the embodiment of the present application, the whole application program is generally split into a plurality of sub-services, that is, micro services. Different micro services are independent and do not interfere with each other, can be independently compiled, upgraded and deployed, and expose the services to the outside through an interface API (application program interface), and provide the services to the outside as a whole. For example, the first application may be split into multiple sub-services, e.g., the first service, the second service, the third service … … may each be deployed on a different service node. As shown in fig. 2, the service nodes 101 and 102 correspond to a first service, the service nodes 201 and 202 correspond to a second service, and the service nodes 301 and 302 correspond to a third service … …, however, more service nodes may be included, for example, each service includes more than 3 service nodes, or the application may be split into more sub-services. Because the application program is divided into a plurality of sub-services, when the application program is updated, offline processing can be performed only on one or more service nodes corresponding to one of the sub-services, other service nodes still provide services to the outside, and calling of an external client to the services is not influenced. According to the method and the device, the service of the whole application program is not required to be downloaded, but only the service node of one sub-service can be downloaded, the calling requirement of an external client is not influenced, and the upgrading and updating of the application program are realized.

Specifically, the service control device shown in fig. 2 is capable of implementing communication connection with the service registration device, the gateway device, and each service node. The service control equipment is used for determining a first service node and sending an offline instruction to the first service node; the first service node corresponds to a first service, and the first service is one of a plurality of services included in a first application program.

The first service node is used for receiving an offline instruction sent by the service control device and sending an offline request to the service registration device.

The service registration device is used for deleting the address information of the first service node from the registration list after receiving an offline request sent by the first service node.

The gateway device is used for updating the information of the cache list according to the information of the registration list.

The service control device is further configured to confirm whether the service registration device deletes the address information of the first service node from the registration list; if the service registration equipment is confirmed to delete the address information of the first service node from the registration list, the service control equipment confirms whether the cache list of the gateway equipment contains the address information of the first service node; if the cache list of the gateway device does not contain the address information of the first service node, the service control device sends an instruction for closing the first service node after confirming that the data request of the first service node is processed.

Referring to fig. 3, an exemplary application scenario of the embodiment of the present application is shown. Of course, the embodiments of the present application may also be applied to other scenarios, and are not limited herein. In fig. 3, after receiving an external data request sent by a client, a load balancing server may select a gateway device to process the external data request according to a load balancing policy. And the selected gateway equipment receives the external data request, and selects a service node to process the external data request according to the address information of each service node in the stored cache list. It should be noted that the cache list stored by the gateway device and the registration list stored by the service registration device are kept updated synchronously. In the application, the service control device closes the first service node when determining that neither the registration device nor the gateway device contains the registration information of the first service node, so that a new external data request is not distributed to the first service node by the gateway, and the calling failure of the external data request is avoided. In addition, the first service node is closed after the data request of the first service node is confirmed to be processed, the data request being processed by the first service node is not lost, the calling failure of the external data request is avoided, and the user experience is improved.

It should be noted that the above application scenarios are only shown for the convenience of understanding the present application, and the embodiments of the present application are not limited in any way in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.

The service offline method according to the exemplary embodiment of the present application will be described below with reference to fig. 4 to 7.

Referring to fig. 4, a flowchart of a service offline method provided in an embodiment of the present application is shown. The method shown in fig. 4 is applied to a service control device, which is in communication connection with a service registration device, a gateway device, and service nodes, and may include:

s401, the service control device determines a first service node and sends an offline instruction to the first service node.

In the embodiment of the application, each application program may include a plurality of services, and each service may correspond to one or more service nodes. For example, the first service node corresponds to a first service, and the first service is one of a plurality of services included in a first application.

The service control equipment can control one or more service nodes to be offline and online, can ensure that no external data request is issued to the micro service node needing to be issued in a shutdown mode, can ensure that the micro service node is closed after the data request currently processed by the micro service node is processed, and achieves service gray level issuing without perception of an external client.

In specific implementation, the service control device may select one or more service nodes from a plurality of service nodes corresponding to the service that needs to be offline, and send the offline request. The number of the selected first service nodes is smaller than the number of the service nodes corresponding to the first service. That is to say, generally, at least one service node needs to be guaranteed to be available, the service can be provided to the outside, and the list of the service registration device and the gateway device at least includes at least one service node of the service that needs to be offline, for example, the first service.

In some embodiments, the service control apparatus determining the first service node comprises: when the first service corresponds to a plurality of service nodes, one or more service nodes with low resource occupancy rates are selected from the plurality of service nodes as the first service node. For example, when it is determined that the first service of the first application program needs to be issued by shutdown, the resource occupancy rates of the service nodes of the first service may be obtained, and the service node whose resource occupancy rate is smaller than the second set threshold may be used as the first service node. Or, according to the resource occupancy rate, sequencing from low to high, and determining the service node with the top N bits as the first service node. N is more than or equal to 1 and is less than the total number M of the service nodes contained in the first service node.

In some embodiments, the service control apparatus determining the first service node comprises: when the first service corresponds to the plurality of service nodes, one or more service nodes are randomly selected from the plurality of service nodes to serve as the first service node. In this implementation, one or more nodes may be randomly selected as the first serving node regardless of the state of each serving node.

After determining the first service node, the service control device may send a logoff instruction to the first service node. And after receiving the offline instruction, the first service node sends an offline request to the service registration device, so as to request offline. Generally, after receiving an offline request sent by a first service node and sent by the first service node, a service registration device deletes address information of the first service node from a registration list. Typically, the registration list of the service registration device contains an identification of the available service and address information of the service node contained by the available service.

S402, the service control device determines whether the service registration device deletes the address information of the first service node from the registration list.

In some embodiments, the service control device may send a list request to the service registration device, which sends the registration list to the service control device in response to the list request. The service control equipment receives a registration list sent by service registration equipment, and matches the address information of the first service node with the address information of each service node contained in the registration list; and if the matching result does not exist, determining that the service registration equipment deletes the address information of the first service node from the registration list.

In some embodiments, the service control device may send a confirmation request containing an identification of the first service node to the service registration device for confirming whether the service registration device deletes the address information of the first service node from the registration list. The first serving node identification may be address information of the first serving node or other information that may identify the first serving node. The service registration apparatus may determine whether the first service node information exists in the registration list according to the identifier of the first service node, and send a confirmation message to the service control apparatus to instruct the service registration apparatus to delete the address information of the first service node from the registration list. The service control device is used for receiving the confirmation information sent by the service registration device and determining that the service registration device deletes the address information of the first service node from the registration list according to the confirmation information.

Of course, in some embodiments, after receiving the offline request sent by the first service node and deleting the address information of the first service node from the registration list, the service registration apparatus may actively send a message to the service control apparatus, where the message is used to indicate that the service control apparatus has deleted the address information of the first service node from the registration list. The message may be a message including a registration list, and the service control apparatus determines, according to the registration list and the address information of the first service node, whether the service registration apparatus deletes the address information of the first service node from the registration list. The message may also be a confirmation message containing the identifier of the first service node, and the service control device confirms, according to the message, that the service registration device has deleted the address information of the first service node from the registration list.

The address information of the first service node may include, but is not limited to, an IP address, a MAC address, or a port number of the first service node, which is not limited herein.

S403, if it is determined that the service registration device has deleted the address information of the first service node from the registration list, the service control device determines whether the cache list of the gateway device contains the address information of the first service node.

It should be noted that, after receiving the offline request sent by the first service node and deleting the address information of the first service node from the registration list, the service registration device may send an updated registration list to the gateway device actively or in response to the request of the gateway device, and the gateway device updates the information of the cache list stored in the gateway device according to the information of the registration list. The cache list stored by the gateway device and the registration list of the service registration device are kept updated synchronously. In some cases, there may be some delay in the synchronization process such that the cache list maintained by the gateway device is inconsistent with the registration list maintained by the service registration device. And the gateway device determines the address of the available service node according to the cache list and distributes the external data request to the available service node. Therefore, it is necessary to determine that the address information of the first service node requiring offline is no longer stored in the gateway device, that is, it is necessary to determine that the first service node is not in the available service list, so as to avoid sending a new external request to the first service node requiring offline.

In some embodiments, upon determining whether the cache list of the gateway device contains address information of the first service node, the service control device may send a request to the gateway device; the method comprises the steps that service control equipment receives a cache list sent by gateway equipment, and address information of a first service node is matched with address information of each service node contained in the cache list; and if the matching result does not exist, determining that the cache list does not contain the address information of the first service node.

In some embodiments, when determining whether the cache list of the gateway device contains the address information of the first service node, the service control device may send a confirmation request containing an identification of the first service node to the gateway device for confirming whether the cache list of the gateway device contains the address information of the first service node. The first serving node identification may be address information of the first serving node or other information that may identify the first serving node. The gateway device may determine whether the first service node information exists in the cache list according to the identifier of the first service node, and send a confirmation message to the service control device to indicate that the cache list of the gateway device does not include the address information of the first service node. The service control device is used for receiving confirmation information sent by the gateway device, and determining that the cache list of the gateway device does not contain the address information of the first service node according to the confirmation information.

Of course, in some embodiments, after updating the address information of the service node in the cache list, the gateway device may actively send a message to the service control device, where the message is used to indicate that the service control device has updated the cache list, and the cache list does not include the address information of the first service node. The message may be a message including a cache list, and the service control device determines, according to the registration list and the address information of the first service node, whether the cache list of the gateway device includes the address information of the first service node. The message may also be a confirmation message containing the identifier of the first service node, and the service control device confirms that the cache list of the gateway device does not contain the address information of the first service node according to the message.

It should be noted that, after the first service node sends the offline request, each gateway device may further store the address information of the first service node, and at this time, the first service node continues to provide the service to the outside. Therefore, the service control device needs to confirm that the address information of the first service node is not stored on all gateway devices gateway.

S404, if it is determined that the cache list of the gateway device does not include the address information of the first service node, the service control device sends an instruction to close the first service node after determining that the data request of the first service node is processed.

In order to avoid the loss of the external data request being processed by the first service node, in the embodiment of the application, after the data request of the first service node is confirmed to be processed, an instruction for closing the first service node is sent, so that the call of the external client to the application program is not failed, and the unaware halt issue of the external client is realized.

In some embodiments, the service control device confirming that the data request of the first service node is processed comprises: the service control equipment determines first preset time according to the historical processing time of each data request, and after the first preset time, the service control equipment confirms that the first service node finishes processing the data processing request. For example, historical processing data of each data request may be acquired, an average processing time or a longest processing time may be determined, and a first preset time may be determined according to the determined average processing time or the determined longest processing time, so that the first preset time is greater than the average processing time or the longest processing time. For example, the average processing time period of the data request is 90S, and the first preset time period may be set to 120S. Thus, after 120S, the data request is generally processed, and a close command may be sent to the first serving node.

In some embodiments, the service control device confirming that the data request of the first service node is processed comprises: the method comprises the steps that service control equipment obtains resource occupancy rate of a first service node, and when the resource occupancy rate is smaller than a first preset threshold value, it is determined that data requests of the first service node are processed. For example, the resource occupancy rate is different when the service node has a data request to process and when there is no data processing request. When the resource occupancy rate is less than a first preset threshold, it may be determined that the service node has no data request processing. The determination of the first preset threshold may be empirically or statistically derived.

In some embodiments, the service control device confirming that the data request of the first service node is processed comprises: and the service control equipment receives the confirmation information sent by the first service node after the data processing request is processed, and determines that the data processing request of the first service node is processed. In this implementation, it may be arranged that the service node may actively send an acknowledgement message to the service control device for indicating that the data request has been processed.

In this embodiment of the application, the service control device may implement offline control of a child node of one of the services included in the application program, without having to offline the service corresponding to the entire application program, so that the application program can still provide the service to the outside when the service node is updated, and an external client invoking the application program is unaware of this, thereby implementing gray-scale publishing of the application program service, improving processing performance and updating efficiency of the application program, and improving user experience. In addition, the service control device in the embodiment of the application closes the first service node when it is determined that neither the registration device nor the gateway device includes the registration information of the first service node, so that a new external data request is not distributed to the first service node by the gateway, and the call failure of the external data request is avoided. In addition, the first service node is closed after the data request of the first service node is confirmed to be processed, the data request being processed by the first service node is not lost, the calling failure of the external data request is avoided, and the user experience is improved.

Referring to fig. 5, a flowchart of a service offline method according to another embodiment of the present application is provided. The method shown in fig. 5 is applied to a service registration device, where the service registration device is communicatively connected to a service control device, a gateway device, and service nodes, and the method may include:

s501, the service registration device receives an offline request sent by the first service node, and deletes the address information of the first service node from the registration list.

S502, the service registration device sends the updated registration list to the gateway device, and the updated registration list is used for indicating the gateway device to update the cache list stored in the gateway device according to the updated registration list.

S503, the service registration apparatus sends a message to the service control apparatus, where the message is used to indicate that the service control apparatus has deleted the address information of the first service node from the registration list.

In some embodiments, the service registration device sending the message to the service control device comprises: the service registration device sends a message containing a registration list to a service control device; the message is sent by the service registration device after receiving a list request sent by the service control device, or the message is sent by the service registration device after receiving an offline request sent by a first service node and deleting address information of the first service node from a registration list.

In some embodiments, the service registration device sending the message to the service control device comprises: the service registration device sends a confirmation message containing a first service node identifier to a service control device, wherein the confirmation message is used for indicating that the service control device deletes the address information of the first service node from a registration list.

Referring to fig. 6, a flowchart of a service offline method according to still another embodiment of the present application is provided. The method shown in fig. 6 is applied to a gateway device, which is in communication connection with a service control device, a service registration device and service nodes, and may include:

s601, the gateway device receives the updated registration list sent by the service registration device, and updates the cache list stored by the gateway device according to the updated registration list.

S602, the gateway device sends a message to the service control device, where the message is used to indicate whether the cache list of the gateway device contains address information of the first service node.

In some embodiments, the gateway device sending the message to the service control device comprises: the gateway equipment sends a message containing a cache list to service control equipment; the message is sent by the gateway device after receiving a list request sent by the service control device, or the message is sent by the gateway device after updating address information of the service node in the cache list.

In some embodiments, the gateway device may further receive an external data request for the first application, and select an available service node for processing the external data request according to the updated cache list. It should be noted that the gateway device determines the address of the available service node according to the cache list, and assigns the external data request to the available service node. Since the service control device confirms that the cache list of the gateway device does not store the address information of the first service node needing to be offline, a new external request can be effectively prevented from being sent to the first service node needing to be offline. And other service nodes corresponding to the first application program can still provide services and process external data requests. After the first service node is stopped, the external client can still call the first application program without stopping sending the request, and the grey scale release without perception of the external client is realized.
