main microservices: Gateway, Eureka and Open Feign. |
| It is used to solve Linkis's service discovery and registration, unified gateway, request forwarding, inter-service communication, load balancing and other issues. |
| At the same time, Linkis 1.0 will also provide the supporting for Nacos; the entire Linkis is a complete microservice architecture and each business progress requires multiple microservices to complete.</p><h2><a aria-hidden="true" tabindex="-1" class="anchor anchor__h2 anchorWithStickyNavbar_y2LR" id="architecture-diagram"></a><strong>Architecture diagram</strong><a class="hash-link" href="#architecture-diagram" title="Direct link to heading">#</a></h2><p><img src="/assets/images/linkis-microservice-gov-01-c677653c7ded2c8b47cd3a4b48f3eee8.png"></p><h2><a aria-hidden="true" tabindex="-1" class="anchor anchor__h2 anchorWithStickyNavbar_y2LR" id="architecture-introduction"></a><strong>Architecture Introduction</strong><a class="hash-link" href="#architecture-introduction" title="Direct link to heading">#</a></h2><ol><li><p>Linkis Gateway<br> |
| <!-- -->As the gateway entrance of Linkis, Linkis Gateway is mainly responsible for request forwarding, user access authentication and WebSocket communication. |
| The Gateway of Linkis 1.0 also added Label-based routing and forwarding capabilities. |
| A WebSocket routing and forwarder is implemented by Spring Cloud Gateway in Linkis, it is used to establish a WebSocket connection with the client. |
| After the connection is established, it will automatically analyze the client's WebSocket request and determine which backend microservice the request should be forward to through the rules, |
| then the request is forwarded to the corresponding backend microservice instance.<br> |
| <!-- --> <!-- --> <!-- --> <!-- --> <a href="/docs/1.1.3/architecture/microservice_governance_services/gateway">Linkis Gateway</a></p></li><li><p>Linkis Eureka<br> |
| <!-- -->Mainly responsible for service registration and discovery. Eureka consists of multiple instances(service instances). These service instances can be divided into two types: Eureka Server and Eureka Client. |
| For ease of understanding, we divide Eureka Client into Service Provider and Service Consumer. Eureka Server provides service registration and discovery. |
| The Service Provider registers its own service with Eureka, so that service consumers can find it. |
| The Service Consumer obtains a listed of registered services from Eureka, so that they can consume services.</p></li><li><p>Linkis has implemented a set of its own underlying RPC communication schema based on Feign. As the underlying communication solution, Linkis RPC integrates the SDK into the microservices in need. |
| A microservice can be both the request caller and the request receiver. |
| As the request caller, the Receiver of the target microservice will be requested through the Sender. |
| As the request receiver, the Receiver will be provided to process the request sent by the Sender in order to complete the synchronous response or asynchronous response. |

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</p><p></p> |
