Specifically, referring to FIG. 5, FIG. 5 is a working principle diagram of a resource management component and a control component of a cloud computing system of an application example, and the details are as follows:

(1) The resource management component will install the container environment on each resource node, and upload the preset application operating environment image (such as jdk, etc.) and operation scripts such as application startup script and shutdown script; directly start the corresponding image when deploying the application That is, there is no need to install an additional application runtime environment.

(2) The user logs in to the management platform, clicks to create an application, and the user can enter the following information:

2.1) Enter a unique application name;

2.2) Select the memory and disk size required for application deployment;

2.3) Select the source directory of the application code file, and upload the application code for deployment;

2.4) Select the operating environment of the application, and select the corresponding operating environment according to the language and framework used by the application.
