What are the key system design considerations for implementing flash sales and managing high-velocity products in an eCommerce platform?

Question

Accepted Answer

Key considerations for flash sales in eCommerce include scalability, inventory management, user experience, and data analytics.

Scalability: Ensure the system can handle sudden spikes in traffic, e.g., using cloud services like AWS or Azure.
Load Balancing: Distribute incoming traffic across multiple servers to prevent overload, e.g., using tools like NGINX or HAProxy.
Caching: Implement caching strategies (e.g., Redis or Memcached) to reduce database load and speed up response times.
Inventory Management: Real-time inventory tracking to prevent overselling, e.g., using a centralized inventory system.
User Experience: Optimize the checkout process to minimize cart abandonment, e.g., one-click purchasing options.
Data Analytics: Monitor user behavior and sales data to adjust strategies for future sales, e.g., A/B testing for promotions.
