Yeoncheon County Office is a local government office in the northernmost region of Gyeonggi province, Republic of Korea. The office serves county residents by stimulating the local economy, creating jobs, promoting agriculture and livestock industries, and improving educational opportunities and quality of life for its citizens. To support these initiatives, Yeoncheon County Office advocates a program called Lifestyles of Health and Sustainability (LOHAS) Yeoncheon. The office also carries out research and initiates reforms to support low-carbon, green growth.

Yeoncheon County Office implemented a virtualized desktop environment, based on Oracle Virtual Desktop Infrastructure. The office has reduced its yearly carbon emissions by 25% and expects to save about US$606,000 (KRW700 million) per year in PC and server maintenance, once virtualization of its 600 terminals is completed in 2013.

Aging PC Terminals Hindered Green Growth Initiative

A word from Yeoncheon County Office

  • “Oracle Virtual Desktop Infrastructure has reduced our carbon emissions by 25% and is expected to save us around US$600,000 per year. Oracle products work better with our existing security software than applications from any other competitor, helping us prepare for potential threats, such as hacking and information leaks, by strengthening our data security capabilities.” – Kang Young-Koo, Director of Local Autonomy Assistance, Yeoncheon County Office

Yeoncheon County Office was running 600 aging PC terminals at its head and municipal offices. These PC’s had performance issues and errors within two or three months of purchase. The office also spent up to US$100 (about KRW100,000) on maintaining each of its 35 legacy servers per month. The office needed a cost- and energy-efficient alternative that supported its low-carbon, green growth initiative.

Yeoncheon County Office also wanted to centralize administrative control and increase data security to improve how it protected sensitive citizen information—such as tax details and family records—handled on administrative PC’s.

“A data leak of residents’ private information would have cost an estimated US$2.5 million (KRW2.9 billion) for emergency response and legal liability, based on Yeoncheon County’s population of 45,606 people,” said Kang Young-Koo, director of local autonomy assistance, Yeoncheon County Office. “We needed to be prepared for security threats, such as hacking, by strengthening our data security capabilities.”

Yeoncheon County Office also operates 12 lower-level municipal offices in towns and townships across Yeoncheon County. These municipal offices are often located more than 40 kilometers from the county office. Yeoncheon County Office had to send personnel to these offices to assess resources, such as printers and photocopiers, fix minor PC breakdowns, and perform system upgrades, and each incident could take up to a day. There were also delays when carrying out tasks, such as electronic payments at a town or township office that required a connection to the county office over a network line.

In addition, having numerous offices caused problems for those who needed to work remotely or to access fixed-PC resources deployed at different locations. Yeoncheon County Office needed a work environment providing access to identical user interfaces and applications, regardless of time and location.

Finally, it was important for Yeoncheon County Office that essential business applications continued to operate correctly at high speeds, with stability and availability in a new virtualized desktop environment.

Why Oracle

An important feature of the Oracle virtualized solution was its ability to ensure the stable operation of more than 100 in-house and third-party administration and data management applications, software, and Websites. Oracle VM VirtualBox also worked better with the office’s existing security software than products from any other competitor.

In addition, Yeoncheon County Office was attracted to the Oracle Solaris operating system.

“Oracle Solaris is backed by renowned technology and was the first UNIX operating system to support virtualization,” said Kang.

“Also, when building a virtualized environment that recognizes multiple storage units as a single pool, storage stability is very important,” he continued. “Oracle’s network-attached storage, Sun ZFS Storage Appliances, have a proven record of stable operation in other implementation projects similar to Yeoncheon County’s.”

Implementation Process

Yeoncheon County Office began its desktop virtualization project on 250 PC terminals in June 2011. The office completed the project in just three months. It then confirmed the new virtualized system was compatible with its existing infrastructure and supported more than 100 in-house and third-party applications and government-related Websites.

In April 2012, Yeoncheon County Office deployed 80 additional Sun Ray Clients at a number of municipal town and township offices and training facilities. This additional deployment took only a month.


Oracle Partner SysGen took charge of every aspect of the virtualization implementation project. It provided environment inspection, project design, system implementation, operation support, tuning, and troubleshooting services.

SysGen has onsite staff to provide rapid support to Yeoncheon County Office.

“SysGen provided great support throughout the project, and we are very happy with its services,” said Kang.
