Kakao noted that CEO Jeong visited the Kakao Data Center in Ansan on the morning of the 24th to ensure stable service provision. This visit was conducted ahead of the year-end and New Year period, when KakaoTalk traffic surges due to Christmas and New Year greetings, to assess the infrastructure status and the stability of various Kakao services.
The message transmission rate of KakaoTalk is an average of 45,000 messages per second, with a daily average of over 10 billion messages sent and received. At the moment the clock strikes midnight on December 31st turning into January 1st, a massive traffic surge occurs, exceeding three times the average traffic. Additionally, during major events, traffic can increase up to ten times the usual amount.
After receiving reports on the operational status of the data center and measures to ensure stability, CEO Jeong encouraged the crew (employees) working on-site by saying, "The data center is like the heart of Kakao services," urging them to connect everyone’s daily lives safely with a sense of mission that thanks to their efforts, users can share important moments through KakaoTalk.
Kakao has made every effort to ensure that the important moments of users' connections can be maintained stably through their expertise in handling peak traffic. Based on this experience, they plan to maintain system integrity during the year-end and New Year period while ensuring service stability through server expansion, emergency personnel deployment, and traffic distribution operations.
Previously, Kakao has established and implemented a system to enhance stability through systematic response to failures, strengthening monitoring systems, conducting failure drills, practicing information security, building redundancy systems, and Business Continuity Plans (BCP).
The Kakao Data Center in Ansan, located on the Hanyang University ERICA campus in Gyeonggi Province, has a total floor area of 47,378 square meters and is a hyperscale data center capable of storing over 100,000 servers with 4,000 racks. Kakao completed the data center in September of last year with the goal of expanding infrastructure to protect users' daily lives and began operations in January of this year.
