After verifying performance through rigorous benchmark tests, Kakao Pay adopted Pure Storage FlashArray//X to optimize workloads primarily for its Relational DataBase Management System (RDBMS). With the Pure Storage platform, Kakao Pay is experiencing greatly improved reliability. Previously, problem resolution could take up to five weeks during failures. However, with Pure Storage delivering up to 99.9999% availability, there have been no disruptions due to storage issues since its implementation. Kakao Pay now spends much less time and fewer resources on system recovery and incident response, greatly enhancing operational efficiency.
This exceptional reliability gave Kakao Pay the confidence to deploy additional Pure Storage FlashArray//C units to provide the perfect balance of cost and performance to support a database upgrade, empowering the company to consistently deliver reliable financial services.
Joo-Seung Park, System Engineer in the Infrastructure Platform Division at Kakao Pay, says, “Pure1 provides us with a user-friendly UX/UI that makes it easier to proactively manage our storage and avoid issues before they arise. Pure’s non-disruptive upgrades also eliminates productivity loss and downtime during data migration and storage capacity expansion, ensuring business continuity.”
The database recovery time decreased dramatically from 12 hours to just 3 hours—a 75% improvement. Data migration time also decreased significantly, from 12 hours to less than 1 hour—a 91% reduction.
Previously, the time and costs of building hundreds of servers limited the company’s ability to scale in a server-based environment. Now Kakao Pay can scale without being constrained by server infrastructure, expanding database capacity in three hours instead of six weeks—a 99.7% decrease.
