SK C&C Completes NH Nonghyup Bank New NH All-One Bank System Construction

[Asia Economy Reporter Yuri Choi] SK Inc. C&C announced on the 21st that it has completed the NH Nonghyup Bank mobile banking app ‘New NH All One Bank’ project.

SK Inc. C&C applied a cloud-based Platform as a Service (PaaS) and Microservice Architecture (MSA) throughout the NH All One Bank system to support stable system operation and uninterrupted app development and deployment.

The platform environment using open source for the first time in the banking sector significantly reduces the maintenance costs of the NH All One Bank system. The microservice architecture designs system functions in small units so that each function operates independently. This enables the development, modification, and deployment of new functions without service interruption.

By adopting the backup system-based ‘Blue-Green’ deployment method, the stability of new service deployment was also enhanced. Blue refers to the existing system environment, and Green refers to the new system environment. The new service version is deployed to Green, and the existing service version is backed up and operated on Blue. If a problem occurs with the new service version, it is urgently applied to Blue, which has the backup environment, allowing the existing system to continue operation.

App performance improvements increased usage speed by more than 30%. Auto Scaling, which automatically expands system performance when users surge, was also applied. Services frequently used by customers, such as expanding the transfer limit through the introduction of a physical one-time password generator (OTP) (1 billion KRW per transaction, 5 billion KRW per day), ▲ mobile certificate application ▲ expanded transferable accounts (funds, retirement pensions) ▲ account password changes ▲ lifting of limit restrictions, were expanded to be available through the mobile app.

Jedu Park, Head of Financial Digital Group 1 at SK Inc. C&C, said, "Based on diverse digital financial system construction experience and professional digital technology capabilities, we achieved stable development through system construction and proactive issue response at each stage." He added, "We will continue to be a digital ITS partner that resolves customer complaints and grow together with our customers’ digital growth."
