At the 'KT Cloud Summit 2026,' a technology conference hosted by kt cloud, the public sector's first private multi-cloud-based Active-Active (A-A) disaster recovery (DR) implementation plan was unveiled, drawing significant attention from attendees.

The KT Cloud Summit 2026 is the company's signature annual event, held this year on September 15 at the Grand InterContinental Seoul Parnas in Gangnam-gu, Seoul. Under the slogan "AX for Your Business," this year's summit served as a venue for enterprise and public sector clients and partners to share real-world cases of implementing cloud and AI-based technologies and services.

Among the various sessions, the segment covering disaster recovery was led by Shin Dongjin, Director of the DX Center at Didim Co., Ltd. (CEO Jang Minho), which is a platinum MSP partner of kt cloud. Director Shin presented on "Public Disaster Recovery Implementation Strategies through Success Stories," sharing practical experience designing and validating multi-cloud A-A architecture as part of the Digital Platform Government (DPG) Integrated Platform project.

The importance of disaster recovery in the public sector has grown considerably in recent times. In April 2026, the Ministry of the Interior and Safety established the "Information System Stability Notice," making it mandatory to establish disaster recovery frameworks according to the information system grade. Subsequently, in June, a plan was announced to begin DR construction, focusing on the critical systems of the National Information Resources Service, accelerating related projects in earnest.

The Digital Platform Government Integrated Platform implementation project introduced at the summit is considered the public sector's first case of private multi-cloud-based A-A deployment. The key feature of this case is that two separate clouds are configured to process traffic simultaneously under normal circumstances, so even if a failure occurs in one cloud, service disruption is minimized.

In this process, the infrastructure and services provided by kt cloud were instrumental. By using GSLB, traffic was distributed 50/50 between the two clouds, so a failure at a specific point would not interrupt service. Additionally, HCX-based dedicated lines ensured reliable database synchronization and session linking between heterogeneous clouds. The kt cloud marketplace's PaaS solutions were also used to provide a consistent deployment and operation framework, even across different cloud environments.

After implementation, various scenarios were tested—including node failures, network connection issues, and full-site outages—to validate the system's stability. This confirmed that the architecture functions not just in documentation but also in real-world situations.

This case is expected to serve as a crucial turning point that will elevate the overall system stability and DR architecture standards across the sensitive domestic IT industry.

Director Shin Dongjin stated, "The significance of this project lies in its status as the 'first' rather than in quantitative achievements. Although we started without any prior examples, we have successfully implemented and validated private multi-cloud-based Active-Active in the public sector. As a result, this will serve as a practical reference for organizations and companies preparing similar projects in the future."
