Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1, the present disclosure provides a fault handling method of a micro-service architecture, which may include the steps of:
S101: determining a fault component which causes the abnormality of the operation parameter under the condition that the abnormality of the operation parameter is detected;
s102: determining a target replacement component having the same function as the failed component;
s103: and disconnecting the downstream component of the fault component from the fault component, and establishing connection between the downstream component of the fault component and the target replacement component.
The execution subject of the above embodiment may be a control end in a micro-service architecture. The micro-service architecture may include at least one service grid system component, each of which may be deployed at an internet data center (IDC, internet Data Center).
The internet data center may be located in different geographical areas (geographic locations). For example, it may be located in different cities or even different countries; or may be located in different areas of the same city, etc.
At least the control plane component and the data plane component with upstream and downstream communication logic may be included in the service grid system component.
The data plane component is used for taking over all the flow entering and exiting the micro service program, and realizing the service management capability of the core.
For example, the service governance capabilities of the core may include several categories of connectivity, security, control, and observation.
Under each category, it may be subdivided into different subcategories.
For example, the connection categories may include sub-categories of load balancing, fusing, fault injection, and retry.
Security categories may include subcategories of authentication, authorization, and encryption.
The control categories may include subcategories of access, rate, and quota.
The observation categories may include sub-categories such as dynamic acquisition, call chain tracking, and monitoring.
In one example, the data plane components may include a sidecar (Sidecar) component, which may be deployed in correspondence with the microservice program.
The control plane is used for pushing contents such as service policy information and the like to the data plane. Taking service management as an example for executing load balancing, the control plane may send random policy information, minimum connection policy information or polling policy information to the boundary car component according to a user instruction.
The control plane may include a Pilot (Pilot) component.
In addition, the service grid system component may further comprise a storage system component for storing service policy information for control plane-oriented pushing. When the control plane pushes service policy information to the data plane, corresponding service policy information needs to be acquired from the storage system component. Wherein each service grid system component may share a storage system component. Or each service grid system component may be provided with a storage system component in its own complement.
Under the condition that each service grid system component is respectively provided with a storage system component in a matched mode, the content stored by each storage system component can be guaranteed by consistency, and the storage contents are identical to each other.
The interaction of the control plane component and the data plane component may include the following two types. The control surface pushes service strategy information to the data surface; and secondly, the data plane component sends a request to the control plane to acquire service policy information. In the case where a large number of data plane components send a large number of requests to a control plane component, it is easy to form a large number of requests to impact the control plane component, which ultimately results in a failure of the control plane component. Once the control plane fails, the failed control plane component can no longer process the requests sent by the data plane component, resulting in failure propagation.
In addition, the interaction between the control plane component and the storage system component also comprises two types, and the control plane component sends a policy request to the storage system component and is issued by the storage system component. Similarly, when the number of requests is large or the amount of data to be issued is large, a failure is likely to occur. The foregoing merely exemplifies one failure forming reason of the micro service architecture, and the actual failure forming reason includes various types, which are not described herein in detail.
The monitoring of the operating parameters of the service grid system components may be performed using service discovery techniques to enable real-time discovery of faults. For example, in the event that a port of the control plane component is detected as being unavailable or the CPU load exceeds a threshold, an abnormality in the operating parameters may be determined. And analyzing the abnormal parameters to determine the fault components causing the abnormal operation parameters.
For example, storage system component failures, pilot component failures, and/or side car component failures may be determined. For example, in a case where it is determined that an operation parameter abnormality occurs in a control plane component in a service grid system component of the a zone, the control plane component in the service grid system component of the a zone may be determined as a failure component.
Second, service grid system components in other territories query for replacement components that have the same function as the failed component. In the embodiment of the application, the service grid system components arranged in different regions can be set to be disaster tolerant. That is, each service grid system component has consistency with each other so that when any one of the service grid system components fails, a replacement node can be quickly determined from the other service grid system components.
For example, in the case where the control plane component in the service grid system component of the a zone is determined to be a failure component, the control plane component in the service grid system component of the B zone may be taken as a substitute node. Based on this, the connection between the downstream component of the faulty component (the data plane component in the service grid system component of the a domain) and the faulty component (the control plane component in the service grid system component of the a domain) can be disconnected, and the connection between the downstream component of the faulty component can be switched to the control plane component in the service grid system component of the B domain.
For single failed components, fail-safe (FailSafe) fault-tolerant mechanisms may be implemented, for multiple failed components or cluster faults, fast fail-over (FailFast) fault-tolerant mechanisms may be implemented, as well as fail-over (failo ver) fault-tolerant mechanisms. Additionally, for failed components, a failure automatic recovery (FailBack) fault tolerance mechanism is included.
Through the scheme, under the condition that the abnormal operation parameters in the micro-service architecture occur, the rapid positioning and connection conversion of faults can be realized, and the functions of multiple activities in different places are realized. The normal operation of the micro-service architecture is satisfied.
As shown in fig. 2, in one embodiment, the replacement component for which the failed component is determined to have the same function in step S102 may further include the following sub-steps:
s201: determining a plurality of candidate replacement components having the same function as the failed component;
s202: the target replacement component is determined from the candidate replacement components according to a predetermined rule.
In the case where service grid system components provided at different geographical locations are set to be disaster tolerant to each other, storage system components in each service grid system component may be determined as candidate replacement components having the same function.
In addition, the control plane component in each service grid system component can be determined as a candidate replacement component with the same function; or a storage system component in each service grid system component may also be determined as a candidate replacement component having the same functionality.
The predetermined rule may be a spam rule. For example, there are A, B, C service grid system components for three zones. The candidate replacement components of the first through third orders may be determined (illustratively) sequentially in the order A, B, C based on factors such as the geographic location of each service grid system, the hardware condition of each service grid system, and the like. That is, in the event of a failure of a service grid system component in any of B, C zones, the service grid system component in zone a may be determined as a candidate replacement component. In the event of a failure of a serving grid system component of the a zone, a serving grid system component of the B zone may be determined as the target replacement component.
By the scheme, in the case that a plurality of candidate replacement components exist, the target replacement component can be directly determined in a mode of directly according to the preset rule. The time of mutual comparison may be omitted so that the target replacement component is selected in the most efficient manner.
As shown in fig. 3, in one embodiment, determining a target replacement component from candidate replacement components according to a predetermined rule includes:
s301: determining a physical distance of the failed component from each candidate replacement component;
S302: a target replacement component is determined from the plurality of candidate replacement components based on the physical distance.
Illustratively, A, B, C regions are Beijing, nanjing, guangzhou, respectively. In the case that the control plane component in the service grid system component of Beijing is determined to be faulty, the physical distance from Beijing to Nanj and the physical distance from Beijing to Guangzhou can be tested respectively.
By distance comparison, it can be obtained that the physical distance from south Beijing to Beijing is shorter than the physical distance from Guangzhou to Beijing. Based on this, the control plane component in the service grid system component of south Beijing may be determined as the target replacement component.
By the above scheme, when the component in any region fails, the target with a relatively close distance can be selected to replace the component according to the physical distance. Therefore, the time delay condition of service processing can be reduced to the maximum extent after the target replacement component is put into operation.
In one embodiment, the micro-service architecture includes service grid system components disposed in different regions;
the service grid system component includes a plurality of functional components having an upstream-downstream relationship, each functional component performing a different function.
In the current embodiment, the service grid system components may be located in different territories. For example, the different regions may be different cities or different countries. The service grid system component is used as a main body for acquiring and executing the service strategy, and a plurality of functional components with upstream and downstream relations can provide service for users in corresponding cities or countries nearby, so that the access efficiency of the users in corresponding geographic positions is improved.

The service grid system component may include a storage system component and a service policy enforcement component having an upstream-downstream relationship. And the service policy enforcement component may be further comprised of a control plane component and a data plane component.
The solid line in fig. 4 represents a schematic of upstream and downstream communication of the service grid system components in the absence of a failure. The dashed line may be a schematic of the post-adjustment upstream-downstream relationship in the event of a failure. For example, in the event of a failure of a Beijing control plane component, the Beijing data plane component may be connected downstream of the Guangzhou or Nanj control plane components.
In addition, the system also comprises a service management platform, and the user can issue a strategy information determining instruction through the service management platform, for example, the system can comprise instructions corresponding to the actions of issuing, adjusting, updating and the like of the service strategy information.
By the scheme, under the condition that any node in the service grid system component fails, quick switching can be realized. To meet the demand of multiple activities in different places.
As shown in connection with fig. 5, in one embodiment, the plurality of functional components having an upstream-downstream relationship further includes a distribution layer component;
the function of the distribution layer component comprises that the distribution layer component is used for adjusting the consistency of the storage contents under the condition that the storage system components in the service grid system components of different regions are inconsistent in the storage contents.
The corresponding micro-service architecture of fig. 5 is further refined based on the micro-service architecture shown in fig. 4. Under the condition that the user changes the strategy corresponding to the service governance capability, the distribution layer component can distribute the changed strategy according to the service strategy information change condition of the user on the service governance platform. So as to meet the requirement of adjusting consistency of storage contents of storage system components in service grid system components in different regions.
Illustratively, the user performs policy upgrade on the service governance platform of the region a. The distribution layer component acquires the updated strategy and distributes the updated strategy to the storage system components of all regions so as to meet the requirement of realizing full-scale storage of the storage system components of all regions. Firstly, the consistency of the storage system components in each region can be ensured, and secondly, the storage system components in each region can be realized to be disaster tolerant.
