Kakao, who analyzed the cause of service failure caused by SK C&C Pangyo data center fire on Oct. 15, announced on Oct. 7 that it will go beyond redundancy and go beyond triplexing where three data centers are connected in relation to redundancy of the system, which is the crux of the problem. In addition, a large-scale renovation plan has been proposed, which foresees three times the previous large-scale investment in the next five years and the establishment of a dedicated organization.
Kakao plans to design and build multiplexing throughout the system and designate and manage recovery priorities in view of the importance of services. Koh Woo-chan (Vice President of Kakao Enterprise), Co-Chairman of the Recurrence Prevention Committee of the Emergency Response Committee, said, “We will invest more than triple the amount invested in the past five years to secure talent for stabilization services , technology development and deployment of disaster recovery (DR) beyond triple redundancy over the next five years.” It will take me a year,” she said.
Kakao explained that if the DR system is upgraded to more than triple redundancy, it will have stability that ensures redundancy even in a situation where a data center is incapacitated. It is also reviewing a plan to build a remote DR data center dedicated to the KakaoTalk message broadcasting function.
He also decided to recruit the best information technology (IT) engineering experts in Korea and organize an IT engineering organization under the direct control of the CEO. He also announced that he will create a disaster recovery committee to strengthen its ability to respond rapidly to large-scale failures and conduct intensive preparedness training.
The Ansan data center in Gyeonggi province, which is under construction with a goal of completion in 2024, explained that it is building redundant infrastructure for “24-hour uninterrupted operation” in three areas: power, cooling and communication. The battery compartment and the uninterruptible power supply (UPS) are separated by a fire barrier, so that even if a fire breaks out in the battery compartment, the triple shutdown method is activated to prevent a situation similar to the SK C&C Pangyo data center.
Kakao announced this plan during the annual “if Kakao Dev 2022” developer conference held on the same day. Nam Gung-hoon (former Kakao representative), who was the keynote speaker, said, “I realized that Kakao’s top priority is to provide stable services” and pledged to “always keep that in mind.”
Outsider Lee Hak-yeong (CEO of Greb), chairman of the Cause Investigation Subcommittee, cited insufficient redundancy between data centers and service operations management tools as reasons for the delay at the time, as well as a lack of available resources and manpower after dismissal. Subcommittee chairman Lee explained that the lack of floor space (data center space) required for redundancy was most critical, and that there was no control tower to oversee recovery and response in the early stage of the incident.
