Design a high-concurrency incident ticket correlation platform that can link related tickets and retrieve system status during specific timeframes.
This question is typically asked during the onsite interview round for software engineering candidates at Microsoft. The interviewer evaluates the candidate's ability to design scalable systems that can handle high concurrency and effectively manage data relationships. The focus is on understanding the candidate's approach to system architecture, database design, and handling real-time data retrieval under load.
What the Interviewer Expects
- Identify key requirements for the incident ticket platform.
- Outline a high-level architecture that supports high concurrency.
- Discuss database design choices and their implications.
- Explain how to ensure efficient ticket correlation and retrieval of system status.
- Address potential trade-offs and scaling strategies.
Key Topics to Cover
How to Approach This
- Start by clarifying functional and non-functional requirements with the interviewer.
- Estimate the scale: QPS, storage, bandwidth. This drives your design decisions.
- Draw a high-level architecture first, then deep dive into 1-2 critical components.
- Discuss trade-offs explicitly (e.g., consistency vs availability, SQL vs NoSQL).
- Address failure scenarios, monitoring, and how the system handles 10x traffic spikes.
Possible Follow-up Questions
- How would you handle data consistency in a distributed system?
- What caching strategies would you implement to improve performance?
- Can you explain how you would test the system under high load?

Requirements
To design a high-concurrency incident ticket correlation platform, we first need to establish the key requirements. The platform should:
- Allow users to create, view, and manage incident tickets. 2....
High-Level Design
The high-level architecture can be structured as follows:
- Frontend: A web interface for users to interact with the ticketing system.
- API Gateway: Manages incoming requests and routes them ...
