Step 2 : Distributed and clustered Step 3 : SpringCloud Step 4 : Course schedule
Explaining Springcloud before , Let's talk about the single architecture system first . The so-called monomer architecture is all functions , All in one application .
For example, we will talk about a single product service application later , Provide data and views in one springboot in . Single architecture system has its advantages , If it is convenient for development , Test , Deployment is also convenient , Directly into a jar Or war, Just everything . However, single architecture also has its disadvantages , It is mainly reflected in high access , The upper limit of high concurrency is fixed . For example, a single architecture , Can bear 1000 Visit / second . But the number of visits reached 2000 second / Seconds , It will be very Caton , Serious impact on business , And only rely on the monomer architecture itself , It's hard to break through this bottleneck .
Since the single architecture will have performance bottlenecks , So we have to solve it . The solution is usually distributed and clustered .
But what do distributed and cluster mean respectively ？ This is not clear in a word or two .... The webmaster doesn't want to throw a lot of concepts directly to the students , Let the students who have not been in contact add more clouds and fog , So the webmaster will explain the monomer architecture first , Then gradually transform the monomer Architecture , Finally, make it a distributed and clustered system , By participating in this process , Only then can we perceptually contact and understand what is distributed and cluster .
SpringCloud It's just a set of tools , Help you easily build such a Clusters and distributed shelves come out .
The next course , The webmaster will start from Start with a simple single station system , Then change it step by step to the composition cloth + Cluster system . In the process of transformation , Will gradually introduce the service registry Eureka, client Ribbon,Feigh, Open circuit protection Hystrix, Configure service , Concept and usage of message bus and so on . Follow the stationmaster step by step , almost SpringCloud You can master it through the preliminary application of .
SpringCloud A lot of content , It will unfold in the following rhythm
