KT Corporation is South Korea’s largest telephone services and broadband provider and played a significant role in that nation’s rapid and widespread adoption of digital communication technologies. The company sells wired and wireless phone services, high-speed Internet services, Internet Protocol Television (IPTV), voice over Internet Protocol (VoIP) and wireless broadband (WiBro) services. The company is also a significant provider of IT services, including consulting and systems integration, and enterprise services, such as data stored in a cloud system.
Like many telecommunications companies in the United States, KT handles device sales in connection with its wireless phone services. In 2012, the launch of the Galaxy S III and the iPhone 5 were expected to be major events for the consumer smartphone industry. In anticipation of huge demand for these phones, KT began examining a system for handling the smartphone pre-sales.
After looking at Oracle, SQL Server and MySQL, the developers at KT chose Postgres Plus Advanced Server with its integrated performance, security and management enhancements and Oracle compatibility software provided by EnterpriseDB. Choosing to deploy the new, mission-critical system using PostgreSQL, which is at the core of EnterpriseDB’s Postgres Plus Advanced Server, represented another step forward in the company’s plans to deploy open source software to replace its current database deployments. The company is an important supporter of Postgres as a replacement for costly, traditional databases, and is a longtime partner of EnterpriseDB’s.
KT’s adoption of Postgres represents one of the largest migrations from proprietary databases onto such a new standard. The company was also aggressively shifting its hardware from RISC-based Unix to x86 Linux for its cloud infrastructure to take advantage of the flexibility, cost savings and performance of HP standards-based x86 hardware. The solution deployed to support the pre-order system combined open source infrastructure software and EnterpriseDB’s Postgres Plus Advanced Server.
“We have a rewarding partnership with EnterpriseDB and are actively expanding our deployment of Postgres Plus Advanced Server throughout our company,” said Jungsook Jaegal, General Manager, IT Architecture team, IT Strategy and planning BU at KT. “We were able to quickly roll out the new mobile phone order system using Postgres Plus Advanced Server, proving the value of EnterpriseDB.”
KT's systems received and successfully processed more than 30,000 orders in the first 60 seconds of opening for pre-sales of the iPhone 5. KT has identified several additional workloads to migrate onto Postgres Plus Advanced Server based on the performance and the cost savings of using Postgres. KT's database expense for Postgres Plus Advanced Server was more than 90 percent less than other solutions.
“We have been deploying Postgres Plus to handle mission-critical and non-mission critical workloads,” said Jaegal. “But the success of handling the mission-critical order system convinced us that Postgres Plus from EnterpriseDB has significant value in the enterprise.”
