This repository contains the Pizza Order App system, structured using a microservices architecture. It includes an Identity Service for handling user authentication, authorization, and profile data; a Restaurant Service for managing restaurants and pizza menus; an Email Service for sending email notifications; a Search Service for searching restaurants and pizzas based on location; an Order Service for managing pizza orders; and a Payment Service for processing payments. The services communicate via asynchronous messaging.
