Case Study: KT (Korea Telecom) achieves cost-efficient, scalable public cloud and competitive advantage with NexentaStor (Nexenta)

KT Leverages Nexenta Cost Efficiency to Win Competitive Advantage over Other Cloud Service Providers

Korea Telecom (KT), South Korea’s largest integrated telecom provider, needed a more flexible, low‑cost storage platform for its growing public cloud to compete with providers like AWS. The company faced price-sensitive customers, the need to avoid vendor lock‑in, and requirements for scalability, high availability and advanced features (deduplication, compression, replication) while leveraging existing Intel‑based hardware.

KT deployed a NexentaStor High‑Availability cluster on CloudStack, a hardware‑agnostic, software‑defined storage solution that reused current servers and scaled by adding nodes. The turnkey implementation took under six months, cut operational costs (customers report up to ~70% savings versus proprietary systems), improved administrative efficiency and responsiveness, and enabled rapid time‑to‑market and competitive pricing.
