Uber architecture overview in Microservices - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main architectural style used by Uber for its system design?

Uber uses a microservices architecture, where the system is divided into small, independent services that communicate over the network.

beginner

Why does Uber use microservices instead of a monolithic architecture?

Microservices allow Uber to scale individual components independently, deploy updates faster, and isolate failures to improve reliability.

intermediate

What role does the 'Dispatch Service' play in Uber's architecture?

The Dispatch Service matches riders with nearby drivers by processing location data and availability in real-time.

advanced

How does Uber ensure data consistency across its distributed microservices?

Uber uses event-driven communication with message queues and eventual consistency patterns to synchronize data across services.

intermediate

What is the purpose of the API Gateway in Uber's system?

The API Gateway acts as a single entry point for client requests, routing them to appropriate microservices and handling authentication and rate limiting.

Which architectural style does Uber primarily use?

A Microservices

B Monolithic

C Client-Server

D Peer-to-Peer

Uber uses microservices to build scalable and independent components.

What is the main function of Uber's Dispatch Service?

A Handle notifications

B Process payments

C Store user profiles

D Match riders with drivers

The Dispatch Service matches riders with nearby drivers in real-time.

How does Uber handle communication between microservices?

A Direct database sharing

B File transfers

C Event-driven messaging

D Synchronous HTTP calls only

Uber uses event-driven messaging for asynchronous communication and data consistency.

What is the role of the API Gateway in Uber's architecture?

A Route client requests and handle security

B Store all data

C Manage driver locations

D Process payments

The API Gateway routes requests and manages authentication and rate limiting.

Why is microservices architecture beneficial for Uber?

A It reduces the number of servers needed

B It allows independent scaling and faster deployments

C It simplifies the codebase into one file

D It eliminates the need for databases

Microservices enable independent scaling and faster updates.

Explain the key components of Uber's microservices architecture and how they interact.

Think about how requests flow from users to services and how services communicate.

Describe how Uber achieves scalability and reliability using microservices.

Consider how breaking the system into parts helps handle more users and failures.
