Industry: Telecommunications

Who

Korea Telecom (KT) is South Korea’s largest telecommunication service provider with 40 million users. With deep wired and wireless expertise, KT has tremendous strength in fiber optics, digital multimedia services and both wired and wireless broadband services.

[1] KT installed Altibase on an IBM P590Q system with 4 x 1.5 GHz and 16 GB of memory.

Problem

KT was plagued by inefficiencies in its core information system. Since all of KT’s processing, detecting, analyzing and controlling functions were entangled in a single system, dysfunction became the norm. This gave rise to four critical issues.

The existing system configuration was unstable when high volumes of data were being processed.

KT experimented with a few solutions that compromised stability with the hope of increasing overall performance. Unfortunately, the tradeoff resulted in an unstable system that did not perform well.

Overloaded and bogged down by multiple processes tied into a single system, KT was stymied. Expanding the system for better performance and stability meant splitting the processes.

Upgrading the system for this type of expansion was difficult to implement and came with a hefty price tag. The total related costs were untenable.

Solution

KT has adopted Altibase’s hybrid architecture into its abnormal traffic detection, analysis and control system since 2009.[1] Altibase‘s hybrid architecture filled KT’s need for speed, utility, reliability and stability – all with a single solution. KT could focus on what mattered most, that is, hot data or most frequently used data as stale and less frequently used data was automatically stored on disk and was retrieved mainly for reference only. The net result was the better and more efficient use of DB.

Results

KT has been empowered with the ability to analyze data in real time and react accordingly.

KT has profited from Altibase’s hybrid architecture capitalizing on in-memory tables for frequently accessed, current data while keeping less active, historical data on on-disk tables.

KT was able to move away from batch processing to real time processing.

Altibase’s built-in replication feature and resultant active-standby system have allowed KT to deliver real time and non-stop service.

The number of active servers has been reduced to 4 from over 20.

System resource usage is down by 65%.

By using the parallel architecture model, on-demand system expansion has become easier.
