"Fix the Vaccine Reservation Glitch" LG CNS Troubleshooter Steps In to Save the Day

Government Requests Support from IT Giants
Architecture Optimization Team Urgently Deployed
Pre-Reservation System Issues Diagnosed

The government has requested support from domestic IT conglomerates for the COVID-19 vaccination pre-registration system, and LG CNS has stepped in as a relief pitcher by deploying its in-house problem-solving team.

According to the IT industry on the 28th, LG CNS recently deployed its Architecture Optimization Team to diagnose issues, propose alternatives, and conduct test trials for the COVID-19 vaccination pre-registration system. Preparations are also underway for the pre-registration of 98,000 college entrance exam candidates, excluding third-year high school students, starting from 8 PM that day.

The Architecture Optimization Team is an in-house LG CNS organization composed of about 20 experts who handle system overloads, unexpected issues, and optimization tasks. Some members of this team have been assigned to improve the pre-registration system. This team also acted as problem solvers during the online school opening disruptions for elementary, middle, and high schools last year. When EBS experienced network overload and login delays in its online classes, it requested assistance, and LG CNS urgently deployed the Architecture Optimization Team to normalize the system.

As the Ministry of Science and ICT and the Korea Disease Control and Prevention Agency faced continuous 'blackout' incidents in the COVID-19 vaccination pre-registration system, they held an emergency online meeting on the 22nd with cloud service providers such as Naver and Kakao, as well as system integration (SI) companies including LG CNS and Bespin Global. Public outrage over the vaccine reservation system failures grew, and even President Moon Jae-in issued reprimands, prompting a hurried SOS to domestic IT giants.

The industry believes the cause of this vaccine system blackout is similar to the EBS situation last year. The key is to identify the cause of overload when many users access the system simultaneously, which is presumed to be due to inefficiently structured SQL (query language used to quickly retrieve desired information) related to reservations. The Architecture Optimization Team is currently performing optimization work to improve SQL performance. They are identifying bottlenecks in certain parts of the system and working to resolve network bottlenecks using cloud resources.

Meanwhile, the government plans to improve the COVID-19 vaccination pre-registration system by mid-next month, when reservations for 22 million people aged 18 to 49 will begin. A government official stated, "Since reservations for people in their 20s to 40s will be in full swing from August, relevant ministries and the private sector will join forces to operate a practical task force (TF) and improve the pre-registration system."
