Aiming to create a new work environment for
combating the covid pandemic and reforming work
stylesLocated in the southern part of the Tama region of Tokyo, Tama City isrich in nature surrounded by the Tama River and Tama Hills, and hasflourished as the core city of Tama New Town, the largest residential
development in Japan.
Since several years ago, Tama City Hall has been considering andresearching the introduction of teleworking into their staff work
environment as part of their efforts to reform work styles. Against thisbackdrop, the covid pandemic grew increasingly grave, and in
response to this, the City Hall embarked on the development of a newwork environment compatible with teleworking from around July 2020,
with the goal of promoting measures against covid and reforming workstyles.
In preparing for the teleworking environment, the Tama City Hall
considered adopting thin client terminals that do not leave data in themainframe as a means of preventing data breach in the event data got
lost, etc. Mr. Ryuichi Yabe, Chief of the Information Policy Section,
Planning Policy Depar tment, Tama Cit y Hall, talks about therequirements of terminals for teleworking as follows.
"For staf f to be able to work comfor tably, we decided that theterminals should have the same specifications as the FAT terminals
t h at we h ad b e e n us i n g unt i l t h e n. We a l s o t h o u g ht t h at anenvironment running on a client OS rather than a server OS would
serve us better for starting the teleworking environment as early as
possible.

Adopting a proposal that leverages "Remote PC
Array" capable of minimizing the burden of system
environment changes on staff while keeping costs low
Tama City Hall invited partner companies to propose teleworking
solutions based on the requirements for teleworking. They thencompared and discussed the proposals presented to them, fromvarious angles.
"In adopting the telework solution, we compared and studied variousoptions, including building a virtual desktop on-premise using theVirtual Desktop Infrastructure (VDI) method, a desktop virtualizations e r v i c e ( D a a S: D e s k t o p a s a S e r v i c e) p r o v i d e d b y atelecommunications carrier, and migrating to the new Municipal
Information System Resilience Improvement Model proposed by the
Ministry of Internal Affairs and Communications (a solution that adopts
Mic rosof t 3 6 5)." ( Yabe) O ne of the proposals rec ommended
teleworking solution making use of "Remote PC Array.""Remote PC Array" provides all-in-one CPU, memor y, storage,
network switches, management software, etc., necessary for thevirtual desktop infrastructure, allowing installation with little or nochange to the existing business environment. It also allows use ofWindows 10 Pro as the terminal OS.

Your Reliable Cloud Computing Partner"Major factors that contributed to choosing this system included the factthat it was easier to implement than other systems, and that it waspossible to use the telework terminals with the same operational feel as
the existing FAT terminals, thus reducing the burden imposed on staff due
to changes in the system environment." (Yabe)
Moreover, the possibility of introducing the system at a low cost wasanother reason why "Remote PC Array" was chosen. Ms. Naoko Mori ofthe Information Policy Division, Planning and Policy Department, TamaCity Hall, says the following.
“Cost has been a major issue for us in implementing a teleworkingenvironment. Because "Remote PC Array" does not require a hypervisor,
costs can be reduced compared to the cost of installing a typical VDI. InTokyo Tama Cityaddition, fewer components running meant lower maintenance andChief, Information Policy
operation costs. Being able to reduce the cost of such installation andSection, Planning andmaintenance operations has proved to be a huge advantage. We also
Policy Department
appreciated the fact that we didn't have to make any major changes to existing
Ryuichi Yabe
connections." Mr. Jun Igarashi of Sales Department 1, Sales Division 2,
Axio Corporation, who proposed this system, explains the key points.
In the case of municipalities, the issue of separating networks is a key point. VDI is inevitably costly
and burdensome to maintain and manage. In this respect, Remote PC Array meets needs in terms ofcost and operational load, which we believe is why it was well received.”
As a result of these considerations, Tama City Hall decided to adopt a teleworking solution thatutilizes "Remote PC Array.”

Building a two-plan teleworking environment using 200 terminals, with thefirst objective being to familiarize staff with the teleworking environment
Tama City Hall created two plans with different usage environments andbegan building a teleworking environment with 100 terminals each.
“The first is "Plan 1," in which all terminals used for daily work byemployees in managerial positions and above are shifted to teleworking
terminals. The other is "Plan 2," in which employees in general positions
below the rank of section chief are loaned teleworking terminals to takewith them.” (Yabe)
System implementation was divided into two phases: the terminals andthe infrastructure (remote PC array), and the lines from the infrastructure
to the terminals and their connection methods. The necessary equipment
and tools were procured in November and December 2020. Next, inJanuary 2021, construction of the teleworking environment began, andfrom around May of the same year, test operations were run also for the Tokyo Tama City
purpose of verifications. Finally, in July 2021, teleworking was launched in Chief, Information Policy
Section, Planning andactual work.
Mr. Akiomi Ishikawa, from Group 2, ICT Technology Depar tment, Policy Department
Technology Division, A xio Corporation, who was in charge of the Naoko Moriinstallation says "We needed to set up 200 terminals in a short period oftime, but the simple configuration of the Remote PC Array made that easy, allowing us to complete
the project on time."
This is how Tama City Hall introduced its teleworking environment. However, since this is the firsttime the municipal was embarking on teleworking, the first objective of both plans was to familiarize
their staff with this form of working style.
“In Plan 1, managers are often on the move in government buildings and have many opportunities tosales@atrustcorp.com | www.atrustcorp.com| +886 3 328 8837

use teleworking terminals away from their seats. In Plan 2, for example, although departments that
focus on counter operations have few opportunities to use teleworking terminals in the office,opportunities to use these terminals from home, etc. are gradually being increased to enable staff tobecome accustomed to the teleworking environment. As these efforts progress, we are seeing more
and more opportunities to use telework terminals for meetings, etc., and as a result, we are gradually
going paperless." (Yabe)

The fact that our staff "didn't notice" the new changes in the environment is asignificant achievement. We will continue to use the Remote PC Array toimprove the workplace environment.
One of the goals of introducing teleworking for Tama City Hall was for staff to be able to shift to ateleworking environment without having to make changes to their current work. The key to achieving
this goal was to create a network environment that can accommodate teleworking.
"Key points of the network environment are, for example, how to connect with existing systems anddevices, whether it is possible to shift from wired to wireless without disrupting staff work, andwhether staff can use terminals stress-free during teleworking. We resolved these issues one at atime as we proceeded with the implementation with our partners. One staff member said ''I didn't
even notice'' that the environment had changed. This is a big accomplishment for us." (Mori)
Based on their newly introduced telework environment, Tama City Hall plans to further promote theuse of thin clients for terminals based on the "Remote PC Array.""One of the themes that we hope to achieve is to convert our My Number terminals to thin clients. To
this end, we need to understand the requirements of teleworking and seize the introduction ofteleworking as an opportunity to build a corporate culture in the organization that will encourage staff
to take on the challenges of a new work environment. Moreover, work styles will change as
teleworking progresses, so we hope to work on this through discussions with the human resources
department and other related departments." (Yabe)
