Kakao Pay Securities Conducts IT Disaster Response Drill Simulating Data Center Paralysis

Uninterrupted Service Transition During Major Disasters
Such as Data Center Flooding or Power Outages
Participation of About 40 Technical Staff

Kakao Pay Securities (CEO Shin Hocheol) conducted an 'IT Disaster Response Drill' in the early hours of November 23, simulating a large-scale disaster scenario. The purpose was to check the stability of its systems to ensure uninterrupted transaction services even if a data center (IDC) is shut down.

This drill was carried out under the assumption that one of the two data centers would be completely paralyzed due to flooding or other extreme circumstances. The worst-case scenario, in which an entire center stops operating-not just a simple system error-was simulated as realistically as possible.

The drill took place from 3 a.m. to 8 a.m. on November 23, lasting about five hours, with approximately 40 members from the technology teams of Kakao Pay and Kakao Pay Securities participating. Kakao Pay Securities operates an 'active-active' dual data center system, meaning both centers are running simultaneously. This structure allows the other center to immediately take over work if one experiences a failure. The company explained, "Even during the actual drill, the switch was made without interruption, ensuring business continuity for transaction and inquiry services, and we identified some areas for improvement, which will be addressed."

Through this drill, the company checked the response speed and collaboration system for each disaster scenario, and analyzed the time required for each step and the quality of recovery to identify additional areas for improvement. Moving forward, the company plans to expand the scope of the drills to include verification of a 'triple safety net system' that also covers the cloud.

Kakao Pay Securities stated, "This 'data center neutralization drill' was an important process to check whether users' investment services can truly operate without interruption even in extreme failure situations," adding, "We will continue to strengthen our technical safety net by conducting regular drills and applying a variety of scenarios."
