The high concurrency system is easy to play, and Alibaba's new 100 million level concurrent design quick notes are really fragrant

Preface

How to improve system performance , Designing a reliable system is a problem that every architect or colleagues who are advancing in the direction of architects need to consider . The company's industry , The business scenario determines the evolution process of the system you design , But nothing changes , The ideas of system design and optimization are interlinked （ Of course, if you haven't been in the industry for a long time , There is certainly no need to worry about this kind of problem at present , But work doesn't use , It doesn't mean you don't ask during the interview ）.

How to design a high concurrency system ？ This question must have been asked by some good brothers who went out for an interview , Now the company's recruitment needs are mostly ： High concurrency system experience is preferred . If you don't , He asked you and hung up . If you do work in an Internet company , It's a “ bosses ” perhaps “ Fake big man ”, Then you just show the interviewer on this question , System split , cache ,MQ, Read / write separation , Distribution sub table ,ES Expand the capacity and fight through a series of moves Yours Offer It's not easy to catch ？

Of course , I'm here chattering about a bunch of , No example for you is equivalent to fp, No nutrition . see , Take this opportunity to ,LZ Let's share the record of internal high concurrency system design obtained from Ali's retired brother some time ago , Whether you are new to the industry or have many years of experience , This record will certainly help you ！

No verbosity , Look at the dry goods

Ali high concurrency advanced notes
