Dubbo five years ago, spring cloud two years ago, all lost to this architecture!

5 One of the most frequently asked skills in an interview two years ago and can get a high salary is Dubbo,2 Interview years ago , As long as you have Spring Cloud Project related experience , It's sure to impress the interviewer , Now? ? I'm afraid it's on my resume Dubbo And simple Spring Cloud Technology and experience can't make the interviewer look up to you .

Spring Cloud Alibaba In recent years, it has been widely concerned by many domestic developers , It has also become a popular skill point in the interview , If you even Spring Cloud Alibaba Micro service ecology has never been used , Then you may be out of date .

Take a look at the following dozen questions that I was asked when Ali met three times , Basically, they go deep into Alibaba's Micro Service Architecture  Spring Cloud Alibaba Source level , It seems P7 It's not that easy to get a million dollars a year , See !

Ali P7 Interview questions

1、 How can the registry of microservice registry better prevent concurrent read-write conflicts ?

2、Nacos How to support access to millions of service instances within Alibaba ?

3、Nacos Do you know how to design a high concurrency asynchronous registration architecture ?

4、Eureka Do you know about the multi-level cache architecture of the registry ?

5、Sentinel How to realize the current limiting algorithm of bottom sliding time window ?

6、Sentinel The bottom layer is how to calculate the real-time of online system QPS Of ?

7、Seata How the distributed transaction coordination manager is implemented ?

8、Seata How to design the distributed transaction consistency locking mechanism ?

9、Seata How to implement the distributed transaction rollback mechanism ?

10、Nacos colony CP Architecture underlying class Raft How did the agreement come true ?

11、Nacos&Eureka&Zookeeper Does cluster architecture have brain cleft problem ?

12、 How to design a microservice cloud architecture that can support the use of companies around the world ?

13、RocketMQ How is the architecture designed to support trillions of messages per day ?

14、RocketMQ How to achieve zero message loss in transaction payment scenario ?

After reading, you can answer a few questions ?

as far as I am concerned , If you can answer one of them 2-3 strip , Even if I barely passed .

If you can answer all of these , Then you should be a good technical bull ! You can rest assured to invest in the resume of a large factory !

But if you can't fully answer these questions , I suggest you listen to this 3 lesson , To improve their core competitiveness , This course is specially created by my technical friends , Exclusive decryption topic :
