Gunsan City Hall Adds Virtual Desktop to Public Offices, Significantly Improves Data Security for City Residents

  • Oracle Customer:  Gunsan City Hall
    Location:  Jeollabuk-do, Republic of Korea
    Industry:  Public Sector
    Employees:  1,368
    Annual Revenue:  $500 Million to $1 Billion

Gunsan City Hall is the administrative center of Gunsan, a large city on the west coast of South Korea. The institution manages bureaus for local government administration, port economies, resident living support, construction, and transport. Its 71 departments also operate public service centers for public health, agriculture, water and sewage, and facility management.

In May 2010, Gunsan City Hall began a trial of a virtualized server-based desktop environment to replace 100 of its 1,700 personal computers (PCs) to confirm the system’s interoperability and compatibility with key software and the existing IT environment. It extended the system to another 400 PCs during phase two of the virtualization project in November 2011 and plans to virtualize the remaining 1,200 work PCs by 2013. As a result, the institution expects to save around US$90,000 (100 million KRW) of taxpayers’ money each year in energy, travel, and fuel costs.

Legacy IT Infrastructure Inhibited Productivity

A word from Gunsan City Hall

  • “We wanted a virtual desktop environment to promote low-carbon green growth and prevent personal information leaks. Oracle’s virtualization products have helped us, so that we anticipate saving US$90,000 per annum in energy and fuel costs, as we strengthen security for important data, realize a smart office environment, and become a good role model for information best practices in public institutions.” – Cha Jeong-hee, Information and Communications Officer, Gunsan City Hall

Gunsan City Hall provides the city’s residents with a variety of public services. Residents can register births, deaths, marriages, cars, construction equipment, in addition to filing tax returns. They can also request passports and various licenses and permits. However, the institution was struggling to maintain a stable information technology (IT) infrastructure capable of handling its various public service procedures and millions of sensitive public records, which contained residents’ contact details, tax information, and family histories. It needed to increase the security of residents’ personal information handled on its administrative PCs, and to centralize security control procedures.

In addition, Gunsan City Hall had to replace around 300 PCs each year. A single round of replacements took three to four months, which lowered staff productivity and affected asset management processes. Having PCs at fixed locations also prevented the institution from initiating flexible working schemes for staff, such as for those who are on-call, work remotely, and telecommute.

Gunsan City Hall provides public PCs to help educate residents about IT. However, the PCs were often damaged, and it took up to three hours to reformat data and reinstall software after each IT education course. In addition, it took up to one working day to repair IT system faults, either at the city hall or at any of the institution’s regional public offices.

Finally, Gunsan City Hall wanted to implement a low-carbon, green IT initiative and reduce the energy consumed by 1,700 administrative PCs. Reducing its number of PCs would also improve its office environments by reducing heat, dust, and noise emissions.

Why Oracle

After completing a selection process, Gunsan City Hall decided on Oracle Virtual Desktop Infrastructure, as it would fulfill the institution’s objectives to reduce energy consumption, optimize human resources, strengthen security, and redeploy IT staff to other value-added duties. Gunsan City Hall gave Oracle high marks for stability, performance, and cost efficiency. The solution was also compatible with key software and system infrastructure that the institution was already using for administrative tasks.

“We were impressed that there wasn’t any decrease in network performance, and the virtualized solution could run Korea’s common administration systems, third-party software, and antivirus applications,” said Jeong-hee. “We also liked the solution’s ability to access various relevant government Web sites and the high availability it offered for more than 90% of our applications, including city administration information, asset management, regional human resources management, and other systems.”

Gunsan City Hall chose Oracle Solaris 10 as the operating system for its virtual desktop clients because Oracle developed it from technology used to create the first UNIX operating system with virtualization capability. This meant it was a proven technology for creating stable virtualized environments.

“When creating a virtualized environment that recognizes multiple storage units as a single pool, the stability of the storage units is of utmost importance,” said Jeong-hee. “We chose Oracle Solaris 10 and Sun ZFS Storage Appliances for our virtual desktop environment as they ensure availability and reliability.”

Implementation Process

In 2010, Gunsan City Hall completed the first phase of the project, deploying 100 terminals in three months. From the first phase, the city confirmed the system’s interoperability and compatibility with key software and existing infrastructure. It also received positive feedback from staff.

The institution started the second phase of the project in November 2011, expanding the system to 400 PCs. This stage is now complete and the system is currently operating more than 90% of Gunsan City Hall’s work applications.

Gunsan City Hall plans to complete the implementation of 1,700 virtualized desktop environments by 2013.


Oracle Partner Hyosung Information Systems provided initial support for Gunsan City Hall’s desktop virtualization project. Sysgen Co. Ltd, a professional network IT service providers, based in Jeonju, handled the actual software development and implementation across the entire process, from product examination, to onsite installation and completion.

“Sysgen’s willingness to incorporate our requirements, its active approach to supplying equipment, and its onsite operation support continue to be favorably received,” said Jeong-hee. “Overall, we were satisfied with the data integration and support we received during the project.”
