Looking at the configuration file, we can conclude that the following components will be created in the microservice:

• ContextInfo - standard Pip.Services component for determining the name and description of a microservice.
• ConsoleLogger - standard Pip.Services component for writing logs to stdout,
• LogCounters - standard Pip.Services component for logging performance counters.
• HelloWorldService - the service of our microservice, implemented in step 2. Make note of the service’s descriptor, as it will be used to link the service class to the REST controller.
• HttpEndpoint - standard Pip.Services component that allows multiple services to use a single HTTP port simultaneously.
• HelloWorldRestController - the REST controller we implemented on step 3.
• HeartbeatRestController - standard Pip.Services component that is used to check whether or not a microservice is still up and running by calling GET /heartbeat.
• StatusRestController - standard Pip.Services component for getting the status of a microservice by calling GET /status.
