    • “In a traditional analytics environment, we would have to purchase and maintain large numbers of servers. With Dell EMC Isilon, we have the flexibility of separating compute and storage, we can increase storage respectively when required. This solution allows us to store large volumes of data with in-place analytics in a single repository which enables us to conduct analysis without data ETL processing.”

  • Outcomes

    Accelerating business growth through advanced data lake

    KT expects the number of Olleh Navi users to double within the year due to its advanced user experience and high-quality route data. KT is using big data to enhance its offerings and attract new users. Because Dell EMC Isilon eliminates the necessity for data movement between data storage and an analytics platform, it minimizes data extraction, transformation and loading, and accelerates data analysis time.

    Improving user experience with optimized architecture

    With its optimized architecture, KT Corporation’s Olleh Navi mobile navigation application delivers users with real time traffic conditions and provides the best route to a destination every 5 minutes, versus competitor apps that update every 15 minutes.

    Reducing total cost of ownership by 34 percent

    Through the cost-efficiencies of single volume storage for NAS and Hadoop Distributed File System (HDFS) through Dell EMC Isilon’s multi-protocol feature, the business can reduce its total cost of ownership (TCO) by 34 percent.

    Dell EMC Isilon has native access to HDFS and this means the business no longer have to migrate their data to a separate data appliance. This enables KT Corporation to produce faster analytics results.
