Non-Functional:

Performance:
- The system should support a high number of simultaneous users, estimated to handle at least 100,000 active users concurrently.
- The average response time for fetching tweets or loading user profiles should not exceed 1 second under normal load.
Scalability:
- The architecture should be scalable to handle growth in users and data without significant degradation in performance. This might mean supporting millions of users and tweets over time.
- The system should be capable of horizontal scaling, allowing for additional servers to be added as the user base grows.
Reliability:
- The system should ensure 99.9% uptime to provide a consistently available service.
- The application should handle failures gracefully, with mechanisms in place for data recovery.
Availability:
- The service should be available 24/7, with provisions for planned maintenance to limit downtime.
- Redundant systems should be in place to ensure high availability across different geographical regions.
Security:
- The platform should implement strong security measures, including data encryption in transit and at rest, to protect user information.
- User authentication must follow best practices (e.g., two-factor authentication) to prevent unauthorized access.
Usability:
- The user interface should be intuitive and easy to navigate, enabling users to perform actions (like composing tweets or checking notifications) with minimal effort.
