Sakura Information Systems looking to replace virtual
PC sharing environment on cloud with a simpler,
performance-oriented system
Sakura Information Systems Co., Ltd.
(hereafter "Sakura Information Systems")
created an Azure instance and had beenrunning it as a remote connection point forSEs stationed at customer sites for thepurpose of viewing and editing files on thecompany file server and providing apersonal work environment.
However, the 30-unit Azure instance
operation was not performing well, withdelays in use, and rising operating costs.

Systems explains the situation before theSakura Information
introduction of the system and the process
Systems Co., Ltd.
behind the company's decision to upgrade
Mr. Hiroji Fujimura
the system.
In the previous environment, about 180 SEs
shared 30 virtual PCs built on Azure, which caused frequent freezes anddelays due to the increased number of profiles. We wanted to resolve
this issue without changing the Azure environment somehow, but evenafter rebuilding the virtual PCs, the problem did not improve, so webegan gathering information on a new system.
It was around this time that we learned about the Remote PC Array
from a member of our department and we arranged to visit Asentech's
VDI Innovation Center to see the system in action. After watching ademo of the Remote PC Array 100, we were so impressed with theresults that we decided to purchase one, and immediately proceededwith the test runs.”

The following are the key points in our test run/selection process.
Does it have the speciﬁcations that allow employees to perform their work (especiallydevelopment) smoothly?
Will the performance of the Remote PC Array deteriorate because it will be used as a
private terminal in comparison with the Azure instance, which is used as a sharedterminal?
Is the Remote PC Array more cost-eﬀective than the Azure instance?

"One of the themes that we hope to achieve is to convert our My Number terminals to thin clients. Tothis 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)
The main users at the company are SEs, so we needed at least 8GB of memory for development
work. A model with the highest CPU performance was also desirable. We also wanted to install theunits in the server room in an integrated manner as much as possible, which is why we selected ahigh-end Remote PC Array 100 model with a high integration ratio, high thermal conductivity, andhigh PC cartridge specifications. The latest model of the Remote PC Array, which we recently added
to our system, has customizable memory and SSDs, so it is much more user-friendly than the one we
had before. (Mr. Fujimura)

Reverting back to “on-premise” improves performance and reduces costs
Following these test runs, the company installed 18 Remote PC Array 100 units as the in-houseenvironment for Sakura Information System's SEs. Mr. Fujimura's talks about some of his
impressions after the installation.
Since the Remote PC Array is a one-to-one proprietary terminal, this has improved the performance
aspect, which had been a problem in the Azure environment. Cost-wise, the cost per PC is also lower
than building virtual PCs in cloud services such as Azure or building virtual PCs on a server. In
terms of management, with Azure, it was difficult to intuitively understand how to build and manage
virtual PCs and it took some getting used to. But with the Remote PC Array, one cartridge isequivalent to one physical PC, just like a Windows PC, so it has the advantage of being simple andeasy to understand. Since it is so easy to use, we can use it for RPA and other applications, and we
expect it to be useful over the long haul."Other benefits he mentioned were the high aggregation ratio of 20 PCs per unit, and the ability toremotely operate and manage equipment.

After implementing the system in-house, Sakura Information Systems adopts
the Remote PC Array for its "Sakura Telework Solution" for external sales
Sakura Information System had been recommending VDI mainly to customers when asked about
teleworking systems, but now that they had actually introduced the Remote PC Array in-house andreceived favorable feedback from employees using it, the company decided to roll it out as a service
for external sales.
Accordingly, they decided to offer the "Sakura Telework Solution," a telework promotion solution thatutilizes remote PC arrays and a financial institution-standard data center, and launched the service inJanuary 2022.

Information Systems talks about the Sakura Telework Solution.
“By installing and operating Remote PC Arrays, which can realize atelework environment at low cost and in a short period of time, in adata center that offers high quality in all aspects, including security,
earthquake resistance, and network facilities, we are able to not only
improve business efficiency, but also implement BCP measures at thesame time."

Planning to use Remote PC Array for free-addressing
throughout the company as well
Mr. Tsukada talks about the future development.
"At present, physical PCs are being used at each desk in the office, but
we plan to deploy solutions to address the shift to a free-address officeenvironment, where employees can connect to remote PC arrays via
remote desktop when they come to work, and connect to remote PC
arrays via remote connection apps when they are at home."
