Design an Emergency Notification System
Design a robust disaster or emergency notification system for a large organization, such as a city government, university, or major company.
Core Functionality
The system must enable authorized operators to create urgent alerts and deliver them to affected recipients through multiple communication channels. These channels include:
- Mobile push notifications
- SMS
- Voice calls
- Web banners
Targeting Capabilities
Alerts should be precisely targeted based on various criteria:
- Geography: Target users within specific geographical areas.
- Organization Group: Target predefined groups within the organization (e.g., departments, student bodies).
- Subscription Preference: Deliver alerts based on user-defined preferences.
- Incident Type: Categorize and target alerts based on the nature of the emergency.
Discussion Points
Your design discussion should cover the following key areas:
- System requirements
- API design
- Data model
- High-level architecture
- Delivery workflow
- Scaling strategy
- Reliability guarantees
- Failure handling
- Security considerations
- Monitoring strategies
AI interview prep
Core dilemma
Balancing extreme write throughput and low-latency delivery with stringent reliability, guaranteed delivery, and precise targeting under potentially adverse and high-stress conditions, while managing diverse external channel dependencies.
3 tradeoffs and 3 stress tests locked
Interview prep
Unlock the interviewer X-Ray rubric, tradeoff matrix, stress tests, clarifying questions, and key concepts.
