KT, established in 1981, is a pioneer of South Korea's communications industry. It provides high-speed internet, wired and wireless phone, media, and communications services. In 2011, KT launched its ucloud biz service with 18,000 servers operating on a cloud platform, providing high-performance, secure, and cost-effective services to more than half of the top-20, publically listed companies in Korea and 3,500 corporate customers. KT, which has 85% market share in the domestic cloud market, enables business enterprises to significantly reduce operating expenses.
In a bid to become a global leader in information and communication technology, KT launched a business information system transformation project in 2010 to simplify and integrate core business systems after the merger of KT and its subsidiary KTF in 2009. The project integrated billing, operations support, enterprise resource planning, content management, and business intelligence systems. KT is one of the first large companies in Asia to execute a transformation project of this scale.
In December 2010, KT implemented the KT private-cloud project to support a virtualized environment for the business information project, which would transform its IT infrastructure into a revenue center, rather than just a cost-savings center.
KT plans to apply the best practices and experience gleaned from its private-cloud project to its upcoming public-cloud service, which will deliver value to enterprise customers and enable future expansion into the new markets.
KT decided to implement Oracle Linux, Oracle VM Server for x86, and Oracle Enterprise Manager 12c because the solutions provide a solid foundation for an optimized cloud solution at lower cost.
“We chose Oracle for its reputation for providing open source solutions, which helped us to seamlessly integrate our existing IT infrastructure into the private-cloud environment. We have significantly increased operational efficiency, lowered our investment and operating costs, and are positioned to become a global IT leader,” said Kim Min Hyun, director, cloud operation team, KT.
In late 2010, KT began to implement Oracle VM Server for x86 and Oracle Linux for its internal private-cloud development project. KT also worked with Oracle Advanced Customer Support Services to provide on-site support and ensure high availability and maximize system performance. The new system went live in June 2013. KT migrated the core systems, such as those used for billing and operations support, into the private cloud, and the migration is expected to be complete in April 2014.
After a three-month proof on concept for Oracle Enterprise Manager 12c, KT moved forward with the implementation in March 2013, and the system went live in August 2013.
KT worked with Oracle Partner SIGMA Infocoms Inc. from proof of concept to deployment of Oracle Linux, Oracle VM Server for x86, and of Oracle Enterprise Manager 12c during KT’s private-cloud development project.
“SIGMA Infocoms understood our business requirements, and the team’s technical expertise and experience in the communications and computer industry gave us a strong sense of confidence and contributed to the great success of the KT private-cloud project. It enabled us to realize the benefits of Oracle’ cloud solutions for our project and to maximize our business performance,” Kim said.
