• Proxy microservice design pattern: This is applied using Nginx in the role of proxy. This pattern refers to the proxy for the OrchestratorNewsService, UsersService, and RecommendationService APIs.
• Aggregator microservice design pattern: OrchestratorNewsService performs the role of aggregator for the FamousNewsService, SportsNewsService, and PoliticsNewsServicemicroservices.
• Branch microservice design pattern: This is the pattern that we have used to establish communication between UsersService and RecommendationService, because RecommendationService needs information synchronously from UsersService to finish the task it proposes.
• Asynchronous messaging microservice design pattern: This pattern is applied between OrchestratorNewsService and RecommendationService.
