Case Study: Coupang achieves 24/7 online shopping availability and reduced maintenance costs with Oracle MySQL Enterprise Edition

Coupang Delivers 24-Hour Online Shopping Convenience, Increases Customer Satisfaction, and Reduces Maintenance Costs

Coupang, a fast‑growing South Korean e-commerce company serving over 12 million shoppers monthly with mobile-driven sales and same‑day service expectations, needed to guarantee near‑zero downtime and reliable performance for its business‑critical online ordering system. The company’s challenges included achieving 99.99% availability, real‑time monitoring and efficient backups, the ability for DBAs to make schema changes without service interruption, and scalable performance to handle massive traffic while reducing maintenance costs.

Coupang deployed MySQL Enterprise Edition with Oracle Premier Support, using automatic failover, replication monitoring, performance schema, online schema changes, point‑in‑time recovery and a scale‑out architecture. The result was continuous 24/7 shopping availability, higher customer satisfaction and sales, reduced maintenance overhead, faster DBA productivity, secure recoverability, and a scalable foundation for future enhancements such as multisource replication.
