Step 1: System Architecture monomer talk about
Before explaining Springcloud, let's talk about single architecture system. The so-called monomers architecture is that all functions are placed in an application.
For example, the back talk of a single product service applications, providing data and views in a springboot years.
Single system architecture has its advantages, such as ease of development, testing, deployment is also very convenient, direct tied a jar or war, on what is good.
But single architecture also has its drawbacks, most notably reflected in the high access, high concurrent upper limit is fixed. For example, a single architecture that can withstand 1000 visits / sec. But visits to 2000 times / sec and it will very Caton, seriously affecting the business, and rely solely on single architecture itself, it is difficult to break through the bottleneck.

Step 2: distributed and clustered
Since there will be a bottleneck on the single architecture performance, then the total to solve it. The solution is usually a distributed and clustered to do.
But clusters are distributed and what does it mean?
This is not to say a word or two can clear it. . . . Owners not willing to throw a lot of concepts directly to the students, so there is no contact with students more foggy, so the owners will first explain monomer architecture, then this single architecture gradually transformed, and let and turn it into a distributed cluster system, by participating in this process, we will be able to contact sensibility and understanding in the end what is distributed and clustered.

Step 3: SpringCloud
SpringCloud is a set of tools to help you easily build out of such a cluster and distributed shelf out.
The next course, owners will start from a simple single-station system, and then step by step to transform it into a distributed system + cluster. In the process of transformation, it will gradually introduce the service registry Eureka, client Ribbon, Feigh, circuit protection Hystrix, configuration services, message bus so the concept and usage.
Webmaster follow step by step walk again, almost SpringCloud initial use will be able to grasp it.
