Describe the overall business approach to the hotel booking service being designed. How does it work?

The hotel booking service is typically built as a distributed system that allows users to search for available rooms, view hotel details, make reservations, and manage their bookings.

Main components:

• User Interface — a web or mobile application where the client enters search parameters (dates, city, number of guests).
• Search Service — processes requests, filters hotels by availability, price, rating.
• Booking Service — handles reserving the selected room, checking availability in real-time, creating and confirming bookings.
• Database — stores information about hotels, rooms, bookings, users.
• Payment Gateway — integration for payment processing.

Service workflow:

1. The user enters search parameters.
2. The search service returns a list of available hotels and rooms.
3. The user selects a room and initiates a reservation.
4. The booking service checks availability, reserves the room.
5. The user pays for the reservation via the payment gateway.
6. The system confirms the booking and sends a notification.

Important aspects include handling concurrent requests (to prevent double bookings), scalability, fault tolerance, and data security.
