"Do you have experience in microservice architecture?"
Some time ago, a friend went for an interview, and Ali’s interviewer overwhelmed him with one sentence. In fact, if you don't work in a big company like BAT, it is difficult to get in touch with microservice architecture projects that support hundreds of billions of traffic. But it is also this kind of rarity that makes every big factory scramble for such talents!
The following ten questions were asked by him when he met Ali three times, and they basically went deep into the Spring Cloud Alibaba source code level of Alibaba’s microservice architecture. It seems that the annual salary of P7 million is really not so easy to get. I have seen it!
- How can the registry of the microservice registry better prevent read-write concurrency conflicts?
- Have you ever understood the multi-level cache architecture of the Eureka registry?
- How does Nacos support access to millions of service instances within Alibaba?
- Do you know how to design the Nacos high-concurrency asynchronous registration architecture?
- How does the underlying sliding time window current limiting algorithm of Sentinel come true?
- How does the bottom layer of Sentinel calculate the real-time QPS of the online system?
- How is Seata's distributed transaction rollback mechanism implemented?
- How is the underlying Raft-like protocol of the Nacos cluster CP architecture implemented?
- Does the Nacos&Eureka&Zookeeper cluster architecture have a split-brain problem?
- How to design a microservice cloud architecture that can support companies all over the world?
How many questions can you answer after reading it? As far as I know, if you can answer 2-3 of them, you can barely pass. If you can answer all ten questions, then you should be a proper technical expert! You can safely submit your resume to Dachang! At the same time, in order to help friends in need learn, this Spring Cloud Alibaba study notes are here, it is super clear and detailed!

Summarize
Spring Cloud Alibaba is committed to providing a one-stop solution for distributed application service development. This project contains the necessary components to develop distributed application services, so that developers can 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's distributed application solutions, and quickly build distributed application systems through Alibaba middleware. The study notes above are enough to help many friends learn Spring Cloud Alibaba!
