Noh Kyung-hun, head of the financial customer team at Amazon Web Services (AWS) Korea, said on the 29th, "Once issues such as regulation and security are resolved, financial institutions will start to actively adopt generative artificial intelligence (Gen AI)."
On this day, Noh was a speaker at the '2025 Future Finance Forum' held at the Westin Chosun Hotel in Jung-gu, Seoul. He noted, "The journey of Gen AI has just begun. If compared to a marathon, we are fighting within 5 kilometers," he said.
Noh noted, "The financial sector is making significant efforts to enhance competitiveness through machine learning," and added, "Gen AI is handling tasks that do not require human intervention such as credit evaluation, fraud detection, fraud investigation, and call centers."
Noh stated that the adoption of cloud services in the financial sector is expanding. He explained past cases where the transaction volume increased due to initial public offerings (IPOs), which caused securities firms' home trading services (HTS) and mobile trading services (MTS) to crash. Recently, securities firms have improved these problems by adopting cloud services.
Noh pointed out that a key advantage of cloud services is the ability to 'turn it on and off.' When there are many users, services can be activated to increase server capacity, and they can be turned off during the night when the number of users decreases. Securities firms can utilize this advantage to respond to large events like IPOs.
Noh introduced a survey result indicating that 92% of financial institutions currently use cloud services. He remarked, "Cloud is excellent for responding to rapid changes in the market, obtaining results through quick experiments, and adapting to the market," and said, "In an uncertain situation where market trends cannot be predicted, utilizing cloud services allows for flexible response instead of making large-scale IT investments." He also stated, "53% of respondents are using AWS."
According to AWS, Kookmin Bank transitioned its existing systems to AWS cloud and reduced expenses by about 40%. Korean Re also built a disaster recovery (DR) system in the cloud to enhance its reliability.
Noh stated, "AWS strives to provide everything 'end to end' in cloud services," and noted, "Financial institutions that have confirmed the benefits of cloud innovation are beginning to equip themselves to actively use these services."
Noh also introduced AWS's own AI chip and Amazon's machine learning management tool 'SageMaker,' as well as the generative AI platform 'Bedrock.' Noh mentioned that AWS provides its clients with self-developed chips and CPUs, stating, "In the past, there was skepticism about whether we could use CPUs made by cloud companies, but now 30-40% are using them."
AWS's new CPU 'Graviton4' is 45% faster compared to the previous generation, and energy efficiency has improved by 60%. The AI chip 'Trainium2' exhibits four times faster learning performance and three times higher energy efficiency than the first generation.
