This article is to share with you about how to understand Skywalking, SpringCloudGateway and SpringWebFlux. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

SkyWalking is an open source APM system, including monitoring, tracking, and diagnosing functions for distributed systems in the Cloud Native architecture. The core functions are as follows:

-Analysis of service, service instance and endpoint metrics

Root cause analysis, analyzing the code at run time.

-Analysis of service topology diagram

-Service, service instance and endpoint dependency analysis

-slow services and endpoints detected

-performance optimization

-distributed tracking and context propagation

-Database access metrics. Detect slow database access statements (including SQL statements).

-call the police

SpringCloudGateway provides a library for building API gateways on top of Spring MVC. Spring Cloud Gateway aims to provide a simple and efficient way to route to API and provide them with cross-domain concerns such as security, monitoring / metrics, and resilience.

Features

Spring Cloud Gateway function:

Based on Spring Framework 5 and Spring Boot 2. 0

Can match the route on any request attribute.

Predicates and filters are specific to routes.

Hystrix circuit breaker integration.

Spring Cloud DiscoveryClient integration

Predicates and filters that are easy to write

Request rate limit

Path rewriting

The original Web framework Spring Web MVC included in the Spring framework was built specifically for Servlet API and Servlet containers. The reactive stack Web framework Spring WebFlux was added in a later version 5. 0. It is completely non-blocking, supports Reactive Streams, and runs on servers such as Netty,Undertow and Servlet 3.1 + containers.

Both Web frameworks reflect the names of their source modules (spring-webmvc and spring-webflux) and co-exist in Spring Framework. Each module is optional. An application can use one module, or two modules, or, in some cases, two modules, such as the Spring MVC controller WebClient with react.

The above is how to understand Skywalking, SpringCloudGateway and SpringWebFlux. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
