Oliveyoung Online Store's Display and Its Backend Journey

Oliveyoung pursued a transition to MSA (Microservices Architecture) to solve the problems of limited server scaling and heavy development effort caused by complex dependencies in its existing Monolithic structure.

The new architecture separates data into two areas for serving.

• Static Data: Data provided identically to all users, ensuring fast response times through caching.
• Personal Data: User-specific customized data, managed via a separate API considering business logic and external system dependencies.

In particular, by separating the Static Data API based on data-driven analysis, the team identified the pattern of users not scrolling down to the bottom of the home screen, and optimized network and parsing costs accordingly.

Additionally, to ensure that a failure in a specific system does not lead to a complete service outage, they built CircuitBreaker and multiple Fallback logic, securing the stability to display the home screen under any circumstances.
