Preface
Spring Cloud Alibaba has been open source for some time, I believe many young people have used it. So now, the question is, do you think your knowledge system is complete? Let's take a look at a picture:
Generally speaking, Spring Cloud includes the following components, which are mainly open sourced by Netflix:
Like Spring Cloud, Spring Cloud Alibaba is also a set of microservice solutions, including the necessary components for developing distributed application microservices, so that developers can use Spring Cloud The programming model easily uses these components to develop distributed application services.
Relying on Spring Cloud Alibaba, you only need to add some annotations and a small amount of configuration to connect Spring Cloud applications to Ali microservice solutions, and quickly build a distributed application system through Ali middleware.
Spring Cloud Alibaba feature comparison
As a new implementation under the Spring Cloud system, Spring Cloud Alibaba has more features compared with official components or other third-party implementations such as Netflix, Consul, Zookeeper, etc.:
What components does SpringCloud Alibaba include
Ali open source components
Nacos: A dynamic service discovery, configuration management and service management platform that makes it easier to build cloud-native applications.
Sentinel: Regarding the flow as an entry point, it protects the stability of services from multiple dimensions such as flow control, fuse degradation, and system load protection.
RocketMQ: an open source distributed messaging system, based on high-availability distributed cluster technology, to provide low-latency, highly reliable message publishing and subscription services.

Arthas: Open source Java dynamic tracking tool, based on bytecode enhancement technology, very powerful.
Ali commercial components
As a commercial company, Alibaba launched Spring Cloud Alibaba. To a large extent, the city hopes to help promote its own cloud products by seizing the developer ecosystem. So in the open source community, there are a lot of private goods. I have used this part of the component when I was working in Ali. The overall ease of use and stability are still very high.
Alibaba Cloud ACM: An application configuration center product that centrally manages and pushes application configuration in a distributed architecture environment.
Alibaba Cloud OSS: Alibaba Cloud Object Storage Service (OSS) is a cloud storage service provided by Alibaba Cloud.
Alibaba Cloud SchedulerX: A distributed task scheduling product developed by the Alibaba middleware team, which provides second-level and accurate timing (based on Cron expressions) task scheduling services.
Integrate Spring Cloud components
Spring Cloud Alibaba is a complete set of microservice solution components. It is not enough to rely on Ali's open source components. It is more integrated with current community components. Therefore, Spring Cloud Alibaba can integrate Zuul, OpenFeign and other gateways, and also supports Spring Cloud Stream messages Components.
