Coupang's Back-end Strategy to Handle Massive Traffic

Gogi, Key

#Back-end

This session will explain how Coupang built a low latency and high availability system to improve customer experience. Our efforts started with serving data with relational databases. All product information was stored in and read from database. This architecture had no issues when there was low traffic. However, as traffic increased to a certain degree, it was unable to sufficiently satisfy our latency and availability requirements. Now Coupang’s core back-end system is 99.99% available supported by NoSQL database, cache layers, circuit breakers and other high availability mechanisms. The presentation will focus on Coupang’s know-how in maintaining high availability.
