Evaluation of WhatsApp’s Design
Evaluate the WhatsApp System Design by verifying how it meets critical non-functional requirements like low latency, consistency, and security. Analyze the key architectural trade-offs, specifically the choice between consistency and availability based on the CAP theorem, and the balance between security and latency.
Requirements compliance
We ensure the design meets the following non-functional requirements:
Low latency: We minimize latency through geographically distributed WebSocket servers with local caching, Redis clusters layered over MySQL, and CDNs for media content.
