For every registered user in the application, there exists a corresponding profile that contains application-specific information for that user. In this article, we construct the AccountProfileService, which is responsible for managing this data. The service provides a REST endpoint as well as a MessageQueue listener and persists the profile data in a MongoDB database. We will deploy the application and exercise its REST endpoint using the generated Swagger user interface. We wrap up by viewing the operational metrics using the AccountProfile Grafana dashboard.
