Challenge
Before

The long-running legacy monolith carried a single point of failure; peak-season load · fragmented logins · delayed point and coupon updates hindered both member experience and business growth.

  • We want a benefits service that stays up even at peak season
    Legacy monolith / single point of failure
  • Members want to find and use coupons · subsidies instantly
    Slow search · updates
  • We want to unify logins across multiple services
    No SSO / fragmented auth
  • We want to migrate safely to the new platform without stopping the business
    Live system / large member dataset
Solution
After

Separated Auth (SSO) · Aggregation (BFF) · Benefits Core · CMS into microservices. A fast My Page and single sign-on for members, a platform stable even at peak season for operations, and non-stop business continuity for headquarters — optimizing all three experiences at once.
