At 11 a.m. on the 7th, at the developer conference ‘If Kakao Dev 2022 (hereinafter referred to as If Kakao)’, Kakao analyzed the cause of the service failure caused by the fire at the Pangyo SK C&C data center on October 15 and disclosed measures to prevent recurrence.
This year, If Kakao looked back honestly at what it had lacked this year and focused on moving forward again to create a better world through technology.
In that sense, the four speakers, including Nam Gung-hoon, who gave a presentation on the 7th, the first day of the event, Ko Woo-chan, co-chairman of the Emergency Response Committee’s Recurrence Prevention Measures Subcommittee, Lee Hwak-young, Cause Investigation Subcommittee Chairman (Greb CEO), and Lee Chae-young, Vice Chairperson of the Emergency Response Committee’s Recurrence Prevention Measures Subcommittee, provided services. By sharing analysis of the cause of the failure and improvements, they expressed their intention to use this as an opportunity to make improvements to prevent something like this from happening again.
The first day’s keynote consisted of four topics: ▲Our Social Mission ▲Analysis of the causes of 1015 failures ▲Changing Kakao 1) Technical improvements to prevent recurrence ▲Changing Kakao 2) Future investment and innovation plans.
Nam Gung-hoon, co-chairman of the subcommittee on recurrence prevention measures, expressed Kakao’s social mission and determination to prevent similar accidents from recurring in the ‘Our Social Mission’ keynote. Kakao’s ESG top priority was set as ‘providing services stably’ and announced that it would set action tasks to improve infrastructure from three major perspectives: analysis of past causes, current measures to prevent recurrence, and future investment. He also announced that, led by Ko Woo-chan, co-chairman of the recurrence prevention subcommittee, he will significantly strengthen the infrastructure organization and create a stable service environment.
Hwakyoung Lee, chairman of the cause investigation subcommittee (CEO of Greb), objectively analyzed the causes of Kakao service failures from a third-party perspective in the keynote ‘1015 Failure Cause Analysis’. He cited insufficient redundancy of data centers and operational management tools and lack of available resources as the main causes, and explained in detail why it took time to restore service.
Lee Chae-young, Vice Chairman of the Recurrence Prevention Subcommittee, announced technical improvements to prevent recurrence in the keynote titled ‘Changing Kakao 1) Technical improvements to prevent recurrence.’ The plan is to apply thorough redundancy of the entire system, from infrastructure hardware facilities to service applications, including data center redundancy, data and service redundancy, and platform and operating tool redundancy. Specific improvements were made, such as multiplexing the monitoring system, configuring a multiple data replication structure, and tripling the operation management tool.
Ko Woo-chan, co-chairman of the recurrence prevention subcommittee, presented the company’s own data center disaster prevention measures and IT engineering innovation plans for the next five years in the keynote ‘Changing Kakao 2) Future Investment and Innovation Plan’. An emergency response plan (Business Continuity) to ensure operational stability of the Ansan Data Center, which is currently under construction with a total budget of KRW 460 billion, to secure a dedicated IT engineering organization and talent, and to minimize business interruption due to various natural disasters and man-made accidents. Plan) and the establishment of a data center DR (Disaster Recovery) system were explained.
Following the first day of If Kakao, Kakao held five separate ‘1015 Retrospective’ special sessions on the second day to individually explain the multiplexing technology applied to five areas, including data centers, infrastructure facilities, data, service platforms, and applications. We plan to continue.
Meanwhile, Kakao started with a keynote speech on the 7th and continued until the 9th. About 120 developers from the Kakao community will speak as speakers on ▲Retrospective on the 1015 data center fire ▲AI ▲Backend ▲Cloud ▲DevOps ▲Blockchain ▲Data ▲Frontend ▲ A total of 106 presentation sessions will be held in 12 tracks, including mobile, ESG, and culture. In addition to technology, content introducing Kakao’s practical activities to increase digital responsibility, such as accessibility and technical ethics, will also be released.
