However, if you use ECS , Not enough is the deployment of the project , Or the middleware to be used in the project , such as Redsi,Mysql,Es, We can all deploy directly to cloud services , Through the public network of ECs IP Visit , It greatly improves the efficiency of development .

3、 ... and 、 Cloud server purchase

Now new users only need 35 element , You can buy a Huawei ECs , To use as a study , very nice.

Four 、 Configure security groups
