Vaccine Reservations Without Glitches... LG CNS Becomes the Savior Pitcher

As pre-booking for COVID-19 vaccinations targeting individuals aged 18 to 49 has begun, LG CNS has stepped in as the 'relief pitcher' to prevent a repeat of the system crash.

According to LG CNS on the 10th, the in-house Architecture Optimization Team conducted a thorough analysis over five days (July 23?27) ahead of the pre-booking, improving bottlenecks in the existing reservation service by more than 90%. As a result, the vaccine reservation system, which started operation the previous evening, ran smoothly without any disruptions.

The Architecture Optimization Team is a group of about 20 experts at LG CNS who handle system overloads, emergency situation resolutions, and optimization tasks. Some members of this team were involved in improving the current pre-booking system. The team also provided support during the online school opening disruptions for elementary, middle, and high schools last year.

After the reservation system for those aged 50 to 60 crashed last month causing significant confusion, LG CNS received an urgent support request from the government. Since LG CNS was deployed on the 28th of last month, no system failures have occurred. Throughout more than three rounds of live testing, LG CNS continuously monitored and optimized the system. They also participated in developing features such as verifying whether the last digit of the applicant’s birthdate matches the last digit of the application date, and evenly distributing reservation capacity by medical institution, which were applied to the vaccine reservation system.

Kim Seong-hoon, head of the Korea Social Security Information Service who oversaw the vaccine reservation system improvements, said, "LG CNS’s Architecture Optimization Team played a leading role in resolving system failures," adding, "Thanks to LG CNS’s extensive experience with large-scale IT systems and outstanding technical skills, we were able to resolve this urgent situation directly related to public health."
