Advanced Microservices Cloud Alibaba

Advanced Microservices

Earlier we learned about a set of solutions for microservices, but it is a Netflix-based solution. In fact, we found that many frameworks have stoppedMaintenance, let's take a look at the maintenance of the major components of SpringCloud we have recognized:

Registration center: Eureka (belongs to Netflix, version 2.x is no longer open source, version 1.x is still being updated)
●Service call: Ribbon (belonging to Netflix, stop updating, has been completely removed), SpringCloud Loadbalancer (belonging to SpringCloud official, the current default solution)
●Service downgrade: Hystrix (belonging to Netflix, stop updating,It has been completely removed)
●Routing gateway: Zuul (belongs to Netflix, stopped updating, has been completely removed), Gateway (belongs to SpringCloud official, recommended solution)
●Configuration center: Config (belongs to SpringCloud official)

It can be seen that in the whole set of solutions we used before, more than half of the components are already unavailable, and some components are solved by the official framework provided by SpringCloud. Therefore, we need to find a better solution.The solution is imperative, which leads us to the protagonist of this chapter: SpringCloud Alibaba

Alibaba, as a major Internet company in the industry, has provided a new set of solutions, the official website (Chinese): Spring Cloud Alibaba Reference Documentation

Spring Cloud Alibaba is committed to providing a one-stop solution for microservice development.This project contains the necessary components to develop distributed application services, and it is convenient for developers to easily use these components to develop distributed application services through the Spring Cloud programming model.

Relying on Spring Cloud Alibaba, you only need to add some annotations and a small amount of configuration to connect Spring Cloud applications to Alibaba distributed application solutions, and quickly build distributed application systems through Alibaba middleware.

Currently, Spring Cloud Alibaba provides the following functions:

1 Service current limiting and downgrading: Supports access to the current limiting and downgrading functions of WebServlet, WebFlux, OpenFeign, RestTemplate, and Dubbo, which can be accessed at runtime throughThe console modifies the current limiting and degrading rules in real time, and also supports viewing the current limiting and degrading Metrics monitoring.
2 Service registration and discovery: Adapt to Spring Cloud service registration and discovery standards, and integrate Ribbon support by default.
3 Distributed configuration management: support externalized configuration in distributed systems, and automatically refresh when configuration changes.
4Rpc service: Extend Spring Cloud client RestTemplate and OpenFeign to support calling Dubbo RPC service
5 Message-driven capability: Build message-driven capability for microservice applications based on Spring Cloud Stream.
6 Distributed transactions: Use @GlobalTransactional annotations to solve distribution efficiently and with zero intrusion to businessbusiness issues.
7Alibaba Cloud Object Storage: Alibaba Cloud provides massive, secure, low-cost, and highly reliable cloud storage services.Store and access any type of data in any application, anytime, anywhere.
8 Distributed task scheduling: Provides second-level, accurate, highly reliable, and highly available timing (based on Cron expression) task scheduling services.It also provides distributed task execution models, such as grid tasks.Grid tasks support the even distribution of sea quantum tasks to all Workers (schedulerx-client) for execution.
9Alibaba Cloud SMS service: SMS service covering the whole world, friendly, efficient and intelligent interconnected communication capabilities, help enterprises to quickly build customer contact channels.

As you can see, SpringCloudAlibaba is actually an enhancement to our SpringCloud components, an enhancement framework for SpringCloud, which is compatible with SpringCloud native components and SpringCloudAlibaba components.
