Application Components

An application component implements a service feature of an application. It is in the form of code or software packages and can be deployed independently.

After creating an application on ServiceStage, you can add components to the application. Currently, microservice, web, and common application components are supported. A maximum of 1000 application components can be created for an application.

You can create a static component by setting the component type, framework, runtime system, and component source, and then deploy this component.

In the process of adding a component, you can configure the component using a template (Template) or customize the configuration (Custom).

  • Template provides default configurations of the component type, runtime system, and framework to help you quickly create components.
  • Custom allows you to select the desired component type, runtime system, and proper framework/service mesh.
