BeneFlow is an enterprise employee-benefits platform used by 10,000 companies · 8M members nationwide. On a Java + Spring Boot microservices foundation, it separates SSO · BFF · subsidies/coupons by role, delivering end-to-end gains in member experience and operational efficiency.
The old monolith — plagued by peak-season outages, fragmented logins, delayed coupon updates, and maintenance limits — was Welfare Partners Co., Ltd. — toward a next-generation platform through 14 months of zero-downtime modernization. A business-transformation story.
A leading domestic employee-benefits provider with 10,000 corporate contracts and a base of 8M members. Across many categories — lodging · dining · health · childcare — it is a social-infrastructure service supporting corporate HR strategy and employees' daily lives.
After years in service, the monolith hit its limits — peak-season outages · fragmented logins · operational load. Migrating to a role-based microservices foundation without stopping the business was the key to continuity and growth.
We treated it not as a technical issue but as a management challenge tied directly to usage rate, contract retention, operational efficiency, and business continuity — and modernized accordingly.
Split the monolith by role into Auth (SSO) · Aggregation (BFF) · Benefits Core · CMS. Sessions are shared across a Redis cluster to enable single sign-on, the BFF speeds up per-screen responses, and the cut-over ran with zero downtime while old and new platforms operated in parallel.
