Customer Case

“By introducing container technology and open source software, we were able to reduce TCO (Total Cost of Ownership).
– IT affiliates of Group A

The groupware (400,000 users with 24/7 global service) system of company A was operating commercial middleware products. New architecture was required to reduce the TCO of aging systems, to solve End of Life (EOL) issues, and to respond flexibly and stably to large amount of traffic. The transition of the container environment to open source middleware satisfied the requirements of all services, which is the largest case of application in Korea.

S-Core Services
We designed a system for high availability and high efficiency based on open source technical skills and cloud architect capabilities. By introducing container technology, we achieved infrastructure scalability, cost reduction, and efficiency in development and operation, and built a system with high stability and compatibility by using the latest standard technology open source middleware.

Company A gained the following values by converting and building groupware into an open source middleware system.

Quantitative effect
– Reduced total TCO by using container environment and open source software

Qualitative effect
– Achieved service stability and efficiency in development and operation.
