Case study

KT Corporation improves IT costs and efficiency with open source

Description

KT Corporation (formerly Korea Telecom) is South Korea's largest telephone company. When the company faced constantly increasing maintenance costs for the commercial software in its IT environment, it sought to replace its proprietary software with cost-effective open source solutions. After completing an initial pilot project with its subsidiary kt ds, KT migrated over 50 IT systems, as well as customer-facing services, to Red Hat® Enterprise Linux® and Red Hat JBoss® Enterprise Application Platform. As a result, the company established a standardized, flexible IT architecture, reduced five-year total cost of ownership (TCO) by 89%, and improved efficiency with support for a DevOps development approach.
