It is said that the design of high concurrency system is not difficult at all!

High concurrency

mention “ High concurrency ” I believe you will not feel strange ！ At this time, you should have a lot of high concurrency in your mind ： Business is growing rapidly 、 E-commerce shopping 、 E-commerce is killing in seconds 、12306 Grab tickets 、 Various activities of Taobao tmall

etc. ; All need to use high concurrency , So how to design a high concurrency system to withstand these shocks ？

In fact, this is also a very common interview question , But most candidates don't know how to answer , Where to start . For one Java For programmers ,, It's more about

System architecture level

What about ？

From the original timing seconds , Up to now, the warm-up of various activities 、 Assemble 、 Deposit inflation 、 Ten billion subsidies 、 Cross store full reduction and more complex combination offers

, It's confusing for users , Although these all disturb the rhythm of the user's purchase , But it's still heating up .

Today's Internet Age , High concurrency is a common problem . that , What kind of system is a high concurrency system ？ I'll talk to you today LZ Decrypt the architecture of a typical seckill system in a high concurrency scenario , See how well you know ？

today LZ To answer questions , Prepare a design manual about high concurrency system , It is divided into seven chapters ： The basic chapter 、 Database section 、 Cache 、 Message queuing 、 Distributed services 、 Maintenance 、 Actual combat ; Take you from the foundation to the actual combat ： Little friends who need information , A little zanga collection , Follow me and add a little assistant vx：1426687161  You can get free downloads
