High concurrency

I believe you will not be unfamiliar with the mention of "high concurrency"!At this point, there should be a lot of high concurrency in your mind: rapid business growth, e-commerce shopping, e-commerce seckill, 12306 ticket grabbing, Taobao Tmall various activities, etc.; all need to be usedHigh concurrency, so how to design a high concurrency system to resist these shocks?
In fact, this is a very common interview question, but most candidates don't know how to answer it, and where to start.For a Java programmer, is he more concerned about the
system architecture level
?
From the original timed spike, to the preheating of various activities, group grouping, deposit expansion, tens of billions of subsidies, cross-store full reduction and more complex combination discounts
,Making users confused, although these have disrupted the rhythm of user purchases, they have also maintained a state of continuous warming.
In today's Internet age, high concurrency is a very common problem.So, what kind of system is considered a high-concurrency system?Today, let's decipher the architecture of a typical spike system in high concurrency scenarios with LZ, and see how well you understand it?
Today, in order to answer questions, LZ prepared a manual on high concurrency system design, which is divided into seven chapters: basic articles, database articles, cache articles, message queue articles, distributed service articles,Maintenance articles, actual combat articles; take you from the basics to actual combat: friends in need can click in to find out, click
——[Portal]——
and that's it!
