Ina City Hall, Nagano Prefecture has newly introduced a “remote access solution” that enables remote access to the virtual desktop environment of the city hall operated on the installed “Citrix Virtual Apps and Desktops” in one month. We built a telework environment. Announced by Citrix Systems Japan. The city was able to start full-scale operation of telework in August 2020. Employees who carry out telework can work as usual with the same user experience as when accessing the system inside the city hall, general office, local agency, etc. without being hindered by the performance on the system. It can be executed. Since 2008, the city has distributed thin client terminals to each employee within the agency, and in response to the local government resilience policy in 2015, three layers of My Number, LGWAN, and Internet have been separated. It was. After that, the client environment was switched to a virtual desktop environment based on “Citrix Virtual Apps and Desktops”. Having already implemented Citrix Virtual Apps and Desktops, it was decided that implementing a remote access solution would be the most efficient and fastest way to telework staff. For the introduction of the remote access solution, Citrix’s remote access gateway, Citrix ADC, was adopted to perform two-step verification by accessing the gateway and logging in to the virtual desktop. A method that requires a one-time password for each authentication will be introduced, and users who log in remotely will need prior permission from the management side. Furthermore, the introduction of BYOD (Bring Your Own Device) has reduced operating costs. When the city prepares a terminal and rents it to a teleworking staff member, it is said that it costs about 50,000 to 60,000 yen per year for terminal rental fees and communication costs. If you prepare 50 licenses like Ina City, the annual amount will be about 2.5 million to 3 million yen. The fact that the BYOD method was able to reduce costs to virtually zero in the latter year is a total cost of ownership in the medium to long term as we plan to actively utilize the remote access environment even after the end of Corona and utilize it for work style reform of staff. Significant reduction in cost (TCO). In addition, the city highly appreciates the ease of operation and management of remote access solutions. There is almost no burden on the system operation side in the process of applying for work in a remote access environment and issuing a terminal certificate to BYOD terminals.
