KT said its cloud computing service, "Cloud K," will be sold through SoftBank Telecom Corp., a telecom unit of the SoftBank group.
KT and SoftBank have jointly set up an infrastructure in Gimhae, a city near South Korea's second-largest city, Busan, located close to Japan, to offer services to Japanese companies seeking a reliable data storage center during natural disasters and power outages, it said.
Cloud businesses are services such as data processing and online data storage by mobile devices and computers. In South Korea, a number of major technology firms, such as Samsung Electronics Co. and KT Corp., have moved to enter the fledgling business.
KT, which has been stepping up its businesses outside the telecom service sector, plans to offer cloud computing services in other countries as well in the future, it said.
The global market for cloud computing services is expected to reach US$461 billion in 2015 and around half of the world's top 1,000 companies are expected to use the services by 2015, according to KT.
