Architecture

Microservices Pattern

Display service - Provides the user interface and handles user interaction;
Reverse Proxy - Redirects user requests to the appropriate microservice. Also provides load balancing to improve scalability and improves security because no service is directly exposed to the end-user;
Calendar service - Responsible for the calendar synchronization between different listing services;
User service - Responsible for authentication and authorization aspects;
Property service - Stores and provides all information related to a property;
Website Wrapper - Module that encapsulates each supported property listing website. Generates events regarding reservations but also handles messages produced in the bussiness layer by propagating changes to those websites;
Message Queue - Handles asynchronous and bidirectional communication between business and backoffice layer;
Analytics Service - From public housing market data does analysis on property prices and generates suggestion to property categories .
