Foreword

How to improve system performance and design a reliable system is a problem that every architect or colleagues who are advancing to the direction of architect needs to consider.The industry the company is in, and the business scenarios determine the evolution of the system you design, but the same thing remains the same. The ideas of system design and optimization are the same (of course, if you have just entered the industry for a while, you definitely don’t need to worry about this.This kind of question, but it is not used for the job, does not mean that the interview will not be asked).

How to design a high concurrency system?This question must have been asked by some good brothers who went out for interviews. Now the company's recruitment needs are mostly: Experience in high concurrent systems is preferred.If you don't, he asks you and hangs up.If you do work in a high-concurrency system in an Internet company, and you are a "big guy" or a "pseudo-big guy", then you only need to show the interviewer on this question, system splitting, caching, MQ, reading and writingSeparation, distribution and sub-table, ES expansion, a set of tricks to hit the past Is your Offer still in hand?

Of course, I'm talking a lot here, but I don't have an example to show you that it's equivalent to fp, and it's not nutritious.No, I take this opportunity to share the internal high-concurrency system design record I got from Ali's retired big brother some time ago. Whether you are new to the industry or have many years of experience, this record will definitely be able toHelp you!

Don't be long-winded, let's see the dry goods
