KyivStar, JSC is Ukraine's foremost mobile communications and mobile internet provider, making the company one of the most visible Ukrainian brands. KyivStar's wireless network operates using the global system for mobile (GSM) communication standard and provides coverage accessible to approximately 99% of the Ukrainian population. In October 2010, KyivStar merged with Beeline-Ukraine, a leading provider of landline communications and communication solutions for business clients to create the largest private communications company in the country, serving 25 million subscribers.
KyivStar deployed Oracle Exadata Database Machine to help it effectively serve its more than 25 million subscribers and make its systems fault-tolerant. The company’s IT infrastructure adds 6 billion records daily, totaling 60 gigabytes of data, including call data records (CDRs), so this is no easy task. Oracle Exadata helped the company achieve record-breaking data processing results. It increased financial and analytical calculation performance by 300% to 500%, and provided KyivStar with a foundation to retain the leadership spot in the Ukrainian telecommunications market.
