• Key Features: Data visualization, custom reports, and performance monitoring.
• Tech Stack: Hadoop, Spark, or Tableau.

How These Components Interact

1. User Browses Movies: The user interacts with the UI to browse movies and select a show.
2. Authentication: The user logs in through the Authentication Service.
3. Movie Details: The Movie and Theatre Management Service provides movie details and show timings.
4. Booking: The user selects seats, and the Booking Service initiates the booking process.
5. Payment: The Payment Service processes the payment through a secure gateway.
6. Confirmation: The Notification Service sends a booking confirmation to the user.
7. Recommendations: The Recommendation Engine suggests movies based on the user’s history.
8. Analytics: The Reporting and Analytics Service tracks booking trends and system performance.

Scalability and Performance Considerations

• Load Balancing: Distribute traffic across multiple servers.
• Caching: Store frequently accessed data in memory.
• Database Sharding: Partition the database to handle large amounts of data.
• Asynchronous Processing: Use message queues to handle background tasks.

Real-World Challenges and Solutions

Challenge: Handling Peak Traffic

Solution: Implement auto-scaling to add more servers during peak hours and use caching to reduce database load.

Challenge: Ensuring Data Consistency

Solution: Use distributed transactions and eventual consistency models.

Challenge: Providing Real-Time Seat Availability

Solution: Use WebSockets for real-time updates and optimize database queries.
