Table 2. Contents of Server-Side Directory

Subdirectory	Description
configuration	The Configuration service reads connection properties of vCenter Server, such as FQDN, thumbprint, port, and GUID, and exposes them to Spring Boot components through public accessors.
controllers	The Controller components have the logic to keep open user sessions to the vCenter Server.
gateway	The Session Service interacts with vCenter Server on behalf of the plug-in server. The Session service authenticates the plug-in server with a clone ticket.
model	Object definitions for plug-in server use.
services	Services that implement the plug-in server-side business logic.
store	In-memory database to store custom data for the plug-in.
vim25	Components that communicate with vCenter Server: VimObjectService retrieves data from the vCenter Server, using the Web Services API. ThumbprintTrustManager helps to authenticate the remote side of a secure socket, using the public interface javax.net.ssl.X509TrustManager interface.
SpringBootApplication.java	The Spring Boot Application bootstraps, deploys, and runs the plug-in on an embedded Tomcat application server.

spring-context.xml	Context configuration for plug-in server Spring application.
static/plugin.json	Descriptors for UI components the plug-in adds to the vSphere Client.

The ui/src directory of the remote plug-in sample contains the client-side code for the plug-in. The main source files are in the app subdirectory, which contains an Angular application, including the AppModule, services, and component files.

Table 4. Contents of ui/src Directory

Subdirectory	Description
app/model	Object definitions for plug-in client-side use.
app/services	Services that implement the plug-in client-side business logic
