🔹 Project Flow (Example: Booking Delhi ✈️ Jaipur)

1. User Auth

   • User hits Auth Service (Docker container) → JWT issued after login/signup.

2. Search Flights

   • Request to Flight Search Service → MySQL (Sequelize, ACID) queried for Delhi → Jaipur availability.

3. Create Booking

   • User picks flight → Booking Service creates booking with ACID transaction.
   • Payment executed with idempotency key.

4. Publish Notification

   • Booking Service publishes event to RabbitMQ (async, durable).

5. Send Email

   • Notification Service consumes event → sends confirmation email.
