This repository is the central hub for the Service-Oriented Trip Planner, a comprehensive application developed for the Service-Oriented Architecture course at the University of Twente. The project is designed using a microservices architecture, with each component of the system operating as an independent, loosely-coupled service.
This central repository provides an overview of the entire system and links to the individual repositories for each microservice.
The Service-Oriented Trip Planner is a complete trip planning and reminder system that seamlessly integrates a user-friendly calendar interface with real-time notifications and robust authentication services. By employing a Service-Oriented Architecture with RESTful APIs and asynchronous message queuing, the application offers efficient trip scheduling, timely reminders, and secure user management, demonstrating the power and flexibility of a distributed system.
The application is built on the principles of Service-Oriented Architecture (SOA). The entire system is decomposed into a collection of distinct, autonomous services that communicate with each other over a network.
- Synchronous Communication: Services communicate synchronously using RESTful APIs. For example, the frontend service makes direct API calls to the Calendar or Route services to request or post data.
- Asynchronous Communication: For tasks that do not require an immediate response, such as sending reminders, the system uses a message broker (ActiveMQ). This decouples the services, improving fault tolerance and scalability. For instance, the Reminder Service places a message on a queue, and the Reminder Receiver Service consumes it to trigger an alert at the appropriate time.
The entire environment is containerized using Docker, and Docker Compose is used to orchestrate the deployment and networking of all the services.
The application is composed of the following microservices, each with its own dedicated repository:
The user interface of the application, built with React. It provides the user with an interactive calendar and trip planning interface.
- Repository: SOFrontendReact
Handles user registration, login, and session management using JWT (JSON Web Tokens) for secure communication between services.
- Repository: SOAAuthenticationService
The core of the trip planning functionality. This service manages the creation, updating, and deletion of trips and events in the user's calendar.
- Repository: SOACalendarService
Provides routing and distance calculation functionalities. When a user plans a trip, this service is called to determine the optimal route and travel duration.
- Repository: SOARouteService
Allows users to set reminders for their upcoming trips. This service is responsible for scheduling the reminders.
- Repository: SOAReminderService
An asynchronous service that listens for messages on the ActiveMQ queue. When a reminder is due, it receives the message from the Reminder Service and triggers a real-time alert to the user.
- Repository: SOARemReceiverService
- Frontend: React.js
- Backend: Node.js with Express.js (for REST APIs)
- Database: MongoDB
- Message Broker: Apache ActiveMQ
- Containerization: Docker & Docker Compose, Kuberenetes Orchestration
