CASE STUDY FOR TELECOMMUNICATIONS

+ Overview

AltibaseAltibase is provider of In-Memory Database solutions for real-time access, analysis and distribution of high volumes of data in mission-critical environments.

Korea Telecom (KT)KT is South Korea’s largest telecommunication service provider.

SummaryAltibase empowered KT with the ability to analyze and react to data in real-time, increasing customers loyalty.

In-Memory Database Solution

+ ProblemsKT 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 three critical issues.

The current system configuration was unstable when high volumes of data were being processed. KT experimented with potential solutions that comprised stability with the hopes of increasing overall performance. Unfortunately, the tradeoff resulted in an unstable system that did not perform well either.

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.

In-Memory Database Solution

+ SolutionKT implemented ALTIBASE HDB In-Memory DBMS into its Abnormal Traffic Detection, Analysis and Control System1. ALTIBASE HDB filled KT’s need for speed, utility, reliability and stability – all with a single resolution.

In-Memory Database Solution

1) KT installed ALTIBASE HDB as hybrid database on an IBM P590Q system with 4 x 1.5 GHz and 16 GB of memory.

+ Results KT was empowered with the ability to analyze data in real-time and react

accordingly. KT has profited from ALTIBASE HDB’s Hybrid architecture capitalizing on in-

memory storage for frequently accessed, current data while keeping less active, historical data on-disk.

KT’s reputation, bolstered by unilateral increases in customer satisfaction, loyalty, attraction and retention, is at an all-time high.

KT was able to move away from batch-processing to Real-time processing. ALITBASE HDB’s built-in replication feature and resultant Active-Standby system,

has allowed KT to deliver real-time and non-stop service. The number of active servers has been reduced to 4 from over 20 servers. System resource usage is down by 65%. By using the parallel architecture model, on-demand system expansion has

become a reality.
