The frontend is responsible for rendering the user interface, handling user input, and communicating with the backend via RESTful APIs. The backend handles data storage, retrieval, and synchronization, as well as providing authentication and authorization functionality.

Performance Considerations

• Load balancing: Quizlet uses a load balancer to distribute traffic across multiple instances.
• Content delivery network (CDN): Quizlet utilizes a CDN to cache static assets and reduce latency.
