Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a schematic flowchart of a service port switching method according to an embodiment of the present invention, and as shown in fig. 1, the service port switching method according to the embodiment of the present invention includes:
step S1: and carrying out fault monitoring on the grid instances of the service grid ports of the service priority calling.
Step S2: if the grid instance of the service grid port fails, the micro-service port is switched to be in an available state, and the service grid port is in an unavailable state.
In the above step S1, the device performs fault monitoring on the grid instance of the service grid port to which the service is preferentially invoked. The apparatus may be a computer device for executing the method, and may include, for example, a central server, as shown in fig. 2, including a configuration center and a registration center therein; wherein:
the configuration center is used for carrying out centralized configuration on the information of the client managed by the central server.
The registry performs registration management on the services of the client managed by the central server.
The client managed by the central server can be a plurality of clients, and each client internally comprises a service grid architecture and a micro-service architecture.
A Service Mesh refers to a configurable infrastructure layer (configurable infrastructure layer) for microservice applications. It makes communication between each service instance more fluid, reliable and rapid. The service grid provides a range of functions such as service discovery, load balancing, encryption, authentication, authorization, fuse mode (Circuit Breaker Pattern) support, and others.
The implementation of the service grid is usually to provide an instance of a proxy, which we call "sidecar". The sidecar is included in each service. The sidecar handles mainly inter-service communication, monitoring, and some security related considerations, i.e. any part of the security aspects that can be abstracted from the service ontology. In this way, developers can focus on development, support, and maintenance in the service; the operation and maintenance personnel can maintain the service grid and run apps. Service grid architectures may include Dubbo, Spring Cloud, APP, SDK, and sidecar.
Wherein Spring Cloud is an ordered set of a series of frames. The development convenience of the Spring Boot is utilized to skillfully simplify the development of infrastructure of a distributed system, such as service discovery registration, configuration center, message bus, load balancing, circuit breaker, data monitoring and the like, and the Spring Boot can be used for one-key starting and deployment in a development style.
Sidecar, which is a process that splits the functionality that would otherwise belong to an application into separate processes, can be understood as Sidecar. In a micro-service system, micro-service functions integrated in an application are separated into a sidecar, and the sidecar provides functions of micro-service discovery, registration, service calling, application authentication, speed limitation and the like.
Dubbo is a service framework that enables applications to implement the output and input functions of a service through high performance RPC, which can be seamlessly integrated with the Spring framework.
A service grid port may be understood as a communication interface of a service grid.
Micro-services, a variant of the software development technology, Service Oriented Architecture (SOA) architectural style, advocates dividing a single application into a set of small services, which are coordinated and coordinated to provide the final value to the user. Each service runs in its own independent process, and the services communicate with each other by adopting a lightweight communication mechanism (usually, HTTP-based RESTful API). Each service is built around a specific business and can be deployed independently to a production environment, a production-like environment, and the like. In addition, a unified and centralized service management mechanism should be avoided as much as possible, and for a specific service, a suitable language and tool should be selected and constructed according to the context.
Microservice architectures may include Dubbo, Spring Cloud, APP, and SDK.
Dubbo and Spring Cloud can be referred to above, with APP and SDK being generic terms in the art.
A microservice port may be understood as a communication interface to a microservice.
Since the service grid architecture is a new distributed service architecture and is superior to the micro-service architecture as a whole, the service calls the service grid port preferentially.
The service instance calling the service grid port is called a grid instance; similarly, a service instance that calls a microservice port is referred to as a microservice instance.
The fault monitoring of the grid instances of the service grid ports, which are called by service priority in each client, can be realized through the existing mature technology, and the client corresponding to the network instance with the fault is taken as the target client.
In step S2, if the device detects that the mesh instance of the serving mesh port fails, the device switches the micro-service port to the available state and the serving mesh port to the unavailable state. Referring to the above description, the micro service port in the target client may be switched to an available state, and the service mesh port may be switched to an unavailable state.
If the grid instance of the service grid port fails, switching the micro service port to be in an available state, and switching the service grid port to be in an unavailable state, wherein the switching comprises the following steps:
if the grid instance of the service grid port fails, the dynamic switch preset on the target client is controlled to be switched to the micro service port through the configuration center. A control message may be sent to the target client, such that the target client switches the dynamic switch of the target client to the micro service port in response to the control message. The switching target carried by the control message is a micro service port.
The dynamic switches may be set in each client in advance, and a corresponding relationship with the configuration center in the central server may be established, where the corresponding relationship may include a client number, a dynamic switch number, and a corresponding configuration center number, and it may be understood that the client numbers and the dynamic switch numbers correspond to one another, and the client numbers and the dynamic switch numbers of multiple clients may correspond to the same configuration center number.
The service port switching method further comprises the following steps:
if the grid instance of the service grid port is monitored to be free from the fault, the service grid port is switched to be in the available state, and the micro-service port is in the unavailable state.
The client corresponding to the network instance with the resolved failure may be used as the target client.
If the grid instance of the service grid port is monitored to be free from the fault, switching the service grid port to be in an available state, and switching the micro-service port to be in an unavailable state, wherein the switching comprises the following steps:
and if the grid instance of the service grid port is monitored to be free from the fault, controlling a dynamic switch preset on the target client to be switched to the service grid port through a configuration center. A control message may be sent to the target client to cause the target client to switch the dynamic switch of the target client to the service grid port in response to the control message. The handover target carried by the control message is a serving mesh port.
The description of the dynamic switch is set in each client in advance, and is not described in detail.
The service port switching method provided by the embodiment of the invention carries out fault monitoring on the grid instance of the service grid port which is called by service priority; if the grid instance of the service grid port is monitored to be in fault, the micro-service port is switched to be in an available state, the service grid port is in an unavailable state, hot switching is realized, the service mirror image does not need to be rolled back, the time required by the work of maintaining the mirror image and the time required by rolling back and restarting the service mirror image is reduced, the labor cost is reduced, and the switching efficiency is improved.
Further, the service port switching method further includes:
if the grid instance of the service grid port is monitored to be free from the fault, the service grid port is switched to be in the available state, and the micro-service port is in the unavailable state. Reference is made to the above description and no further description is made.
The service port switching method provided by the embodiment of the invention ensures that the service calls the service grid port preferentially.
Further, if it is monitored that a grid instance of a service grid port fails, switching the micro service port to an available state and the service grid port to an unavailable state includes:
if the grid instance of the service grid port fails, controlling a dynamic switch preset on a target client to be switched to the micro-service port through a configuration center; reference is made to the above description and no further description is made.
If the grid instance of the service grid port is monitored to be free from the fault, switching the service grid port to be in an available state, and switching the micro-service port to be in an unavailable state, wherein the switching comprises the following steps:
and if the grid instance of the service grid port is monitored to be free from the fault, controlling a dynamic switch preset on the target client to be switched to the service grid port through a configuration center. Reference is made to the above description and no further description is made.
The service port switching method provided by the embodiment of the invention completes the switching action by controlling the dynamic switch, thereby further improving the switching efficiency.
Further, the service port switching method further includes:
acquiring a metadata identification bit of a service in a registry, and displaying the metadata identification bit; the metadata identification bits mark service mesh ports or microservice ports. The microservice port may be labeled with a 0 and the service mesh port may be labeled with a 1.
By displaying the metadata identification bits, the target client can be conveniently instructed to switch the dynamic switch to the service grid port or the micro-service port.
The service port switching method provided by the embodiment of the invention is convenient for indicating the target client to switch the dynamic switch to the service grid port or the micro-service port.
Further, the service port switching method further includes:
carrying out fault monitoring on a grid instance of a service grid port for service priority calling to obtain historical fault monitoring data; the time limit of the historical fault monitoring data can be set independently according to actual conditions, and can be selected as historical fault monitoring data half year ago or historical fault monitoring data 1 year ago.
And if the ratio of the service grid port with the fault in the historical fault monitoring data to all the service grid ports is larger than a preset ratio, switching the service port which is called by service priority into a micro service port. The preset ratio can be set autonomously according to actual conditions, and can be in positive correlation change with the time limit of the historical fault monitoring data, namely the preset ratio corresponding to the historical fault monitoring data half year ago can be smaller than the preset ratio corresponding to the historical fault monitoring data 1 year ago.
It should be noted that if a service grid port has multiple failures, it can be marked as a failure and participate in the above calculation.
If the grid instance of the service grid port is determined to have a large-scale fault through the historical data, the service grid is not stable enough, and the service port called by the default service priority can be switched to the micro-service port.
The service port switching method provided by the embodiment of the invention further ensures that the service is normally carried out by setting the service port which is preferentially called by the default service.
Fig. 3 is a flowchart illustrating a service port switching method according to an embodiment of the present invention, and as shown in fig. 3, the service port switching method according to the embodiment of the present invention includes:
step R1: responding to the control message of the service port switched to the available state.
Step R2: executing a service port switching action for switching to the available state according to the metadata identification bit; the metadata identification bits mark service mesh ports or microservice ports.
In the above step R1, the device responds to the control message of the service port switched to the available state. The apparatus may be a computer device that performs the method, and may include, for example, a client, as shown in fig. 2, including within the client a microservice architecture and a services grid architecture. The control message may be sent by the central server to the target client, that is, the target client responds to the control message for switching to the service port in the available state, and the message carries an indication that the service port to which the terminal is switched is the service mesh port or the micro service port.
In the above step R2, the device performs a service port switching action to the available state according to the metadata flag; the metadata identification bits mark service mesh ports or microservice ports. Referring to the above description, if the metadata flag is 0, a micro service port switching action to an available state is performed; if the metadata identification bit is 1, a service mesh port switching action to an available state is performed.
The service port switching method provided by the embodiment of the invention carries out fault monitoring on the grid instance of the service grid port which is called by service priority; if the grid instance of the service grid port fails, the micro-service port is switched to the available state, the service grid port is in the unavailable state, the target terminal responds to the control message of the service port switched to the available state, the service port switched to the available state is hot switched, the service mirror image does not need to be rolled back, the work of maintaining the mirror image and the time required for rolling back and restarting the service mirror image are reduced, the labor cost is reduced, and the switching efficiency is improved.
Further, before the step of responding to the control message of the service port switched to the available state, the service port switching method further includes:
and setting a dynamic switch and establishing a corresponding relation with a configuration center in the central server. At this time, since the control message is not received, the target client having the fault is not determined, that is, the client sets the dynamic switch, and establishes the corresponding relationship with the configuration center in the central server. The corresponding relationship may include a client number, a dynamic switch number, and a corresponding configuration center number, and it may be understood that the client numbers and the dynamic switch numbers correspond to one another, and the client numbers and the dynamic switch numbers of a plurality of clients may correspond to the same configuration center number.
The service port switching method provided by the embodiment of the invention further facilitates the control of the dynamic switch through the configuration center.
Further, before the step of setting a dynamic switch and establishing a corresponding relationship with a configuration center in a central server, the service port switching method further includes:
configuring service grid adaptation information, so that when a service initiates registration, the central server displays a service grid port and a micro-service port in a registration center according to the service grid adaptation information and generates the metadata identification bit. A service grid adaptation layer can be configured in a micro-service architecture in a client to realize configuration of service grid adaptation information, when a service initiates registration, two ports, one is a micro-service port and the other is a service grid port, are exposed in a registration center by the same service instance, and the generated metadata identification bit marks the micro-service port or the service grid port.
According to the service port switching method provided by the embodiment of the invention, the service grid port and the micro service port are displayed in the registration center, the metadata identification bit is generated, and the service port is further switched through the dynamic switch.
The method of the embodiment of the invention is explained as follows:
step 1): a service grid adaptation layer is configured in a client, when a service initiates registration, two ports are exposed in a registration center by the same service instance, one is a micro-service port, and the other is a service grid port. And exposes metadata at the registry indicating whether the grid port or the microservice port is serviced, respectively.
Step 2): a dynamic switch is arranged in a micro-service framework in a client, and a configuration center of a central server is connected with the dynamic switch to set whether the micro-service framework capability is enabled or not. If the switch is set to be closed, the service grid sidecar proxies the flow to realize the service calling service grid port.
Step 3): when the client side initiates service calling, the service grid port is called preferentially by default.
And step 4): when the grid example has a fault, the state of the switch can be switched by the configuration center, so that when the target client initiates service calling, the service grid port is not allowed to be called, and only the micro-service port is allowed to be called. Therefore, the method can realize quick hot switching in the process of not restarting or changing images. The basis for judging the service grid port or the micro-service port is the metadata identification bit on the service instance of the registration center.
Step 5): when the fault is relieved, the switch of the configuration center can be switched back to the strategy of preferentially calling the grid port.
The method of the embodiment of the present invention will be described in detail.
After the traditional micro service is accessed into the grid, the original service framework is not removed, and the micro service framework is selected to be completely used or the service grid is removed through an adapter by configuring a switch. As shown in fig. 2.
After the service in the service grid is started, the micro service frame exposes and registers a port, the service grid also exposes and registers a port, and the service grid or the exposed port of the micro service frame is marked by the metadata identification bit of the registration center.
Both ports normally exposed are capable of service communication, with the difference being one through the mesh sidecar proxy and one using the microservice framework capabilities. By default, client load balancing selects the exposed ports of the grid to perform load balancing instance screening, and initiates a request, as shown in fig. 4, which is described as follows:
1. the service provider sends its instance IP port (122.52.106.253: 28080) to the service provider's grid sidecar
2. The service provider's network sidecar sends the service provider's own instance IP port (122.52.106.253: 28080) and the service provider's grid sidecar's own instance IP port (122.52.106.253: 28081) to the registry for registration.
3. The service consumer sends the subscription service to the grid sidecar of the service consumer.
4. At this point the service consumer's grid sidecar returns a notification to the service consumer carrying its own instance IP port (127.0.0.1: 28082).
5. And also sends subscription services to the registry.
6. The registry sends a notification to the service consumer's grid sidecar carrying the service provider's own instance IP port (122.52.106.253: 28081/28080) of the network sidecar.
And the grid sidecar selects one of the examples (the micro-service frame example or the grid example) through the dynamic switch according to the metadata identification bit, the port establishes service communication between the network sidecar of the service consumer and the network sidecar of the service provider, and the data is transmitted to the service provider through the grid port after the service communication is established.
When a large-scale fault occurs in the service grid architecture, a central switch can be configured, so that only a micro-service port example is selected when a client performs load balancing screening, the grid port is shielded, the capability of a micro-service framework is enabled, and the appeal of rapid disaster recovery and hot switch is achieved. As shown in fig. 5, the following is illustrated:
1. the service provider sends its instance IP port (122.52.106.253: 28080) to the service provider's grid sidecar.
2. The service provider's network sidecar sends the service provider's own instance IP port (122.52.106.253: 28080) and the service provider's grid sidecar's own instance IP port (122.52.106.253: 28081) to the registry for registration.
3. The service consumer sends a subscription service to the registry.
4. The registry sends a notification to the service consumer carrying the service provider's own instance IP port (122.52.106.253: 28080).
The service consumer establishes service communication with the service provider, and after the service communication is established, data are transmitted to the grid sidecar of the service provider through the micro service port.
It should be noted that the service port switching method provided by the embodiment of the present invention may be used in the financial field, and may also be used in any technical field other than the financial field.
The embodiment of the invention can select the service grid port or the micro service port when the routing load is balanced and selected by reserving the capacity of the original micro service framework, double registering two ports and configuring the central switch, thereby achieving the capacity of fast hot switching, and compared with the prior art, the invention has the following beneficial effects:
1. the same mirror image can be rolled back without preparing a rolled back mirror image, thereby reducing the cost
2. The container is not required to be restarted, the hot back-cutting can be quickly carried out, and the failure time is reduced
3. The process is simplified in the deployment strategy, and the same mirror image of a set of templates can support the process.
