Key Microservices for a Simple Uber System:

Key Microservices for a Simple Uber System:

1. 1. Customer Service:

   Handles customer-related functions like authentication, profile management, and ride history. 
2. 2. Driver Service:

   Manages driver authentication, profile details, driver status (available, offline), and vehicle information. 
3. 3. Ride Service:

   Responsible for ride matching, including finding nearby available drivers, estimating ETAs, and managing ride requests. This service might use technologies like quadtrees for efficient location-based queries. 
4. 4. Trip Service:

   Manages the lifecycle of a ride, from initiation to completion, including fare calculation, payment processing, and ride status updates. 

Core Components and Considerations:

• API Gateway:

  Acts as a single entry point for client applications, routing requests to the appropriate microservice. 
• Service Discovery:

  Enables microservices to find and communicate with each other dynamically. 
• Messaging Formats & Communication:

  Utilizing efficient messaging formats (e.g., REST, gRPC) for inter-service communication is crucial. 
• Databases:

  Each microservice owns its dedicated database to ensure data isolation and independent scaling. 
• Scalability & Performance:

  The microservice architecture inherently supports horizontal scaling, allowing individual services to scale based on demand. High availability and low latency are critical non-functional requirements for a ride-hailing system. 
• Decoupling:

  Services should be loosely coupled, allowing for independent development, deployment, and updates without impacting other parts of the system.
