Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Currently, the micro service automatic degradation method generally configures a service degradation policy in a service development stage, when the service is readjusted, a code needs to be modified and the service needs to be reissued for reconfiguration, and service interruption is caused in the reissuing process. Although the dynamic update can be realized based on the components such as the existing configuration center, the updating process needs manual adjustment and triggering, so that the real automatic operation can not be realized, and the degree of automation is low.
Based on the above, the embodiment of the invention provides a method, a device and a computing device for automatically degrading micro-services, which can still realize automatic service degradation when the services are readjusted, and can achieve the effect of higher automation degree.
In particular, embodiments of the present invention are further described below with reference to the accompanying drawings.
It should be understood, however, that the following examples provided herein may be combined with one another to form new embodiments, so long as they do not conflict.
Fig. 1 shows a schematic structural diagram of an automatic micro-service degradation device according to an embodiment of the present invention. The micro-service automatic downgrading apparatus 10 includes: an interface module 11, a first micro-service module 12, a second micro-service module 13 and a call chain tracking module 14.
The interface module 11 may include, among other things, an application program interface (Application Programming Interface, API) gateway. The API gateway can be a server and is used for providing a unique access entry for the outside so as to realize the effects of high cohesion in the system and loose coupling between the systems through the gateway. The API gateway may provide different API gateways for different clients.
In this embodiment, the interface module 11 is configured to receive an external call request. The external call request may be an external internet request or a request of an internal other system, for example, may be a request from a WEB side and an APP side.
The interface module 11 is further configured to generate a first call request carrying a call identifier according to the external call request, and send the first call request to the first micro service module 11. The call identifier is a globally unique identifier generated according to an external call request, and the identifier can be specifically a code. For example, if an external call request is received, the external call request is numbered according to a preset encoding mode, so as to obtain a call identifier. According to the external call request, a first call request carrying a call identifier is generated, which may specifically be: and generating a call identifier according to the external call request, generating a first call request according to service call information in the external call request, and binding the first call request with the call identifier. For example, according to the external call request, the call identifier 100xxxx is generated, and according to the service call information (specifying the call of the first micro service module 12) in the external call request, the first call request directed to the first micro service module 12 is generated, and the first call request is bound to the call identifier 100 xxxx.
It should be noted that, when the interface module 11 receives a new external call request, the interface module 11 generates a new call identifier according to the new external call request.
The first micro service module 12 is one of several distributed micro service modules. The first micro-service module 12 communicates with the interface module 11, and the first micro-service module 12 also communicates with the second micro-service module 13 and the call chain tracking module 14.
In this embodiment, the first micro service module 12 is configured to receive the first call request, generate a second call request carrying a call identifier according to the first call request, and send the second call request to the second micro service module 13. The method comprises the steps of receiving a first call request, specifically: a first call request carrying a call identifier sent by the interface module 11 is received. According to the first call request, a second call request carrying a call identifier is generated, which may specifically be: and generating a second call request according to the call task information in the first call request, and acquiring a call identifier carried by the first call request to enable the second call request to be bound with the call identifier. For example, assuming that the call identifier carried by the first request is 100xxxx, according to the call task information (specifying to call the second micro service module 13) in the first call request, a second call request directed to the second micro service module 13 is generated, and the second call request is bound to the call identifier 100 xxxx.
The second micro service module 13 is one of several distributed micro service modules. The second micro-service module 13 may communicate with the interface module 11, and the second micro-service module 13 may also communicate with the first micro-service module 12 and the call chain tracking module 14.
In this embodiment, the second micro service module 13 is configured to receive a second call request. The second call request is received, specifically: a second call request carrying a call identifier sent by the first micro service module 12 is received.
The call chain tracking module 14 is respectively in communication connection with a plurality of micro-service modules in the distributed micro-service modules. In this embodiment, the call chain tracking module 14 is configured to determine a call relationship between the first micro service module and the second micro service module according to the call identifier. The method specifically comprises the following steps: when the first micro service module 12 receives a first call request carrying a call identifier, the call chain tracking module 14 acquires the call identifier carried by the first call request from the first micro service module 12 and acquires the direction of the call identifier, if the call identifier is determined to be directed to the second micro service module 13, when the second micro service module 13 receives a second call request carrying the call identifier, the call chain tracking module 14 acquires the call identifier carried by the second call request from the second micro service module 13 and acquires the direction of the call identifier, the call chain tracking module 14 judges whether the call identifier carried by the first call request is identical to the call identifier carried by the second call request, and if so, the call relationship between the first micro service module 12 and the second micro service module 13 is determined to be that the first micro service module 12 calls the second micro service module 13. For example, as shown in fig. 2, assuming that the service a is a first micro-service module, the service C is a second micro-service module, when the service a receives a first call request carrying a call identifier 10aabb, the call chain tracking module 14 obtains the call identifier 10aabb from the service a and obtains the direction of the call identifier, if it is determined that the call identifier points to the service C, when the service C receives a second call request carrying the call identifier 10aabb, the call identifier 10aabb is obtained from the service C, and after comparison, it is determined that the call identifier carried by the first call request is the same as the call identifier carried by the second call request, it is determined that the call relationship is that the service a calls the service C; similarly, if the call identifier of the service C points to the service E and the service E also receives the call identifier 10aabb, it is determined that the call relationship calls the service E for the service C.
It should be noted that, the call chain tracking module 14 records the call relationship between each micro service module in real time. When the calling relation among the micro service modules is changed, the calling chain tracking module 14 updates the calling relation among the micro service modules, so that policy configuration is not required to be carried out again when the service is readjusted, and the degree of automation is improved.
The second micro service module 13 is further configured to perform degradation processing on the second micro service module if it is determined that the second micro service module is abnormal; the call chain tracking module 14 is further configured to send a degradation notification to the first micro service module 12 according to the call relationship; the first micro service module 12 is further configured to perform degradation processing on the first micro service module according to the degradation notification. The specific implementation mode can be as follows: when the second micro service module 13 determines that the second micro service module is abnormal, the second micro service module 13 automatically degrades the service, and meanwhile, the second micro service module 13 sends an abnormal message to the call chain tracking module 14; after receiving the abnormal message sent by the second micro service module 13, the calling chain tracking module 14 calls the chain tracking module 14 to determine the micro service module (i.e. the first micro service module 11) related to the second micro service module 13 according to the calling relation, and then calls the chain tracking module 14 to generate a degradation notification and sends the degradation notification to the first micro service module 11; the first micro service module 12 receives the degradation notification and automatically degrades the service according to the degradation notification.
It should be noted that, the present embodiment is not limited to only the first micro-service module and the second micro-service module, but may include more micro-service modules, the call chain tracking module 14 is connected with each micro-service module and records the call relationship of each micro-service module, and when a certain micro-service module is abnormal, the call chain tracking module 14 determines other micro-service modules related to the abnormal micro-service module according to the call relationship and sends a degradation notification to other micro-service modules related to the abnormal micro-service module. The other micro service module related to the abnormal micro service module is generally an upstream module of the abnormal micro service module, and the upstream module refers to the micro service module that sends a call request to the abnormal micro service module. The micro service module can call a basic component, wherein the basic component can comprise message middleware, cache service, database service and the like.
The embodiment of the invention receives an external call request through an interface module 11, generates a first call request carrying a call identifier according to the external call request, sends the first call request to a first micro-service module 11, a first micro-service module 12 generates a second call request carrying the call identifier according to the first call request, sends the second call request to a second micro-service module 13, the second micro-service module 13 receives the second call request, and a call chain tracking module 14 determines the call relationship between the first micro-service module 12 and the second micro-service module 12 according to the call identifier; if the second micro service module 13 is determined to be abnormal, the second micro service module 13 performs degradation processing; the call chain tracking module 14 sends a degradation notification to the second micro service module 13 according to the call relationship, so that the first micro service module 12 performs degradation processing, generates unique call identifiers of call requests each time, and records the call relationship of different call requests, thereby realizing automatic service degradation when the service is readjusted, and achieving the effect of higher automation degree.
In some embodiments, to achieve high availability, the micro service module deploys several application instances. As shown in fig. 3, the first micro service module 12 includes a first service gateway 121 and several instances, and the second micro service module 13 also includes a second service gateway 131 and several instances. Wherein the instance may be deployed on a container platform or virtual machine, etc.
The first service gateway 121 is connected to the interface module 11 and the call chain tracking module 14, and the first service gateway 121 is also connected to a plurality of instances of the first micro service module 12. The first service gateway 121 is configured to receive a first call request carrying a call identifier sent by the interface module 11, generate a second call request carrying a call identifier according to the first call request, and send the second call request to the second service gateway 131. The first service gateway 121 is further configured to implement traffic allocation between the instances based on the load balancing algorithm according to the first call request, record a call state of each instance, and upload call state information of each instance to the call chain tracking module 14.
The second service gateway 131 is respectively connected with the interface module 11 and the call chain tracking module 14, the second service gateway 131 is also connected with the first service gateway 121, and the second service gateway 131 is also connected with a plurality of instances of the second micro service module 13. The second service gateway 131 is configured to receive a second call request carrying a call identifier sent by the first service gateway 121. The second service gateway 131 is further configured to implement traffic allocation between the instances based on the load balancing algorithm according to the second call request, record a call state of each instance, and upload call state information of each instance to the call chain tracking module 14.
The second service gateway 131 is further configured to: judging whether the second micro service module 12 has an abnormal instance or not; if it is determined that the second micro service module 12 has an abnormal instance, after isolating the abnormal instance, calculating a maximum load of the second micro service module 12; determining a request load of the second micro service module 12 according to the second call request; if the request load of the second micro service module 12 is greater than the maximum load of the second micro service module 12, it is determined that the second micro service module 12 is abnormal.
The determining whether the second micro service module 12 has an abnormal instance may specifically be: the second service gateway 131 determines a preset operation duration of the instance of the second micro service module 12 according to the second call request; the second service gateway 131 obtains the current running duration of the instance of the second micro service module 12; if the current running time of the instance of the second micro service module 12 is longer than the preset running time, determining that the instance is an abnormal instance, and determining that the second micro service module 12 has an abnormal instance.
The second call request may include call task information, where the call task information may be information of a task to be executed, and according to the information of the task to be executed, the number of required instances and the number of other micro-service modules to be called may be estimated. For example, assuming that the call task information is order settlement task information, the number of the required examples is estimated to be 2 according to the order settlement task information, and other micro-service modules do not need to be called. The preset operation time length is the operation time length of the obtained instance estimated according to the second call request. Then, according to the second call request, the predetermined operation duration of the instance of the second micro service module 12 may be determined as follows: the number of the required examples in the second micro service module 12 is estimated according to the calling task information of the second calling request, and the preset operation time length of each required example is calculated according to the historical operation speed of the required example. The current running time is the actual running time of the instance. Then, when the actual running time of a certain desired instance is longer than the preset running time, i.e. the instance call times out, the second service gateway 131 determines the instance as an abnormal instance. Different tasks can correspond to different numbers of examples, and preset running time lengths of the different tasks can be the same or different. Alternatively, the second micro service module 12 may also "determine whether an abnormal instance exists" in other manners, which is not limited by the embodiment of the present application.
The isolation exception example may specifically be: when the second service gateway 131 receives the next call request, the second service gateway 131 no longer sends the call request to the anomalous instance.
Wherein, after isolating the abnormal instance, calculating the maximum load of the second micro service module 12 further comprises: acquiring a calling state of a normal instance of the second micro service module 12; determining the residual load of the normal instance according to the calling state of the normal instance; from the remaining load of the normal instance, the maximum load of the second micro service module 12 is calculated. The call state refers to a use state of the instance, if all the instances are used, the use state of the instance is an idle-free state, and if the instances are partially used, the instance is a partial idle state. For example, assuming that the second micro service module 12 includes the unit instances a1, a2 and a3, a3 is determined to be an abnormal instance, a1 and a2 are determined to be normal instances, call states of a1 and a2 are obtained, and if it is determined that the residual loads of a1 and a2 are respectively 100% and 50%, the maximum load of the second micro service module 12 is 1.5 unit instances.
The determining, according to the second call request, the request load of the second micro service module 12 may be: and estimating the number of the required examples in the second micro service module 12 according to the calling task information of the second calling request, so as to estimate the request load of the second micro service module 12.
When the second micro service module 13 determines that the second micro service module is abnormal, the second micro service module 13 performs automatic degradation processing on the service, which may specifically be: when the second service gateway 131 determines that the second micro service module 13 is abnormal, the second service gateway 131 makes the second micro service module execute the call task of a part of the second call requests and reject the call task of another part of the second call requests, or transfers the call task of another part of the second call requests to a task queue. The calling task of a part of the second calling requests can be the calling task with the request load smaller than or equal to the maximum load, and the calling task of the other part of the second calling requests is the rest of the calling tasks except the calling task of a part of the second calling requests in the second calling requests. In such a manner that when the second micro service module 13 is abnormal, the request exceeding the load is transferred to a task queue or refused to be processed in such a manner that the second micro service module 13 is demoted.
Wherein the second service gateway 131 is further configured to: when it is determined that the second micro service module 13 is abnormal, the abnormal information is sent to the call chain tracking module 14, so that the call chain tracking module 14 sends a degradation notification to other micro service modules related to the second micro service module 13 according to the call relationship. If the call chain tracking module 14 determines that the other micro service module related to the second micro service module 13 is the first micro service module 12 according to the call relationship, a degradation notification is sent to the first service gateway 121. The first service gateway 121 is further configured to receive the degradation notification, and perform degradation processing on the first micro service module 12 according to the degradation notification. The first service gateway 121 performs degradation processing on the first micro service module 12, which may specifically be: and regenerating a second call request matched with the maximum load of the second micro service module according to the maximum load of the second micro service module. The second call request matching the maximum load of the second micro service module refers to a second call request having a request load less than or equal to the maximum load of the second micro service module. That is, when the degradation notification is received, the first service gateway 121 transmits the next second call request to the second service gateway 131, and the first service gateway 121 adjusts the task amount requested in the second call request so that the next second call request does not exceed the maximum load of the second micro service module 12, thereby completing the degradation processing of the first micro service module 12.
In some embodiments, the second service gateway 131 is further configured to: detecting an abnormal instance; judging whether the abnormal instance is recovered according to the detection result; and if the abnormal instance is determined to be recovered, performing degradation cancellation processing on the second micro-service module, and sending a degradation cancellation notification to the first micro-service module. Wherein the second service gateway 131 may detect the abnormal instance by sending a timed heartbeat mechanism. When the abnormal instance is restored to normal, the second service gateway 131 may dispatch a portion of traffic to the abnormal instance for processing and monitoring to confirm whether the abnormal instance has been restored. If it is determined that the abnormal instance is recovered, the second service gateway 131 reassigns the call request to cancel the degradation processing on the second micro service module, and sends a recovery message to the call chain tracking module 14, so that the call chain tracking module 14 sends a cancel degradation notification to other micro service modules related to the second micro service module 13 according to the call relationship.
