Realize the system cloud migration to meet EOL in two months-- get rid of the hardware life cycle and greatly accelerate the efforts of DX implementation.

Mr. Takashi Nakahara, head of the system Department of Yiyu Bank of Co., Ltd.

In order to improve the efficiency of all kinds of banking business and clerk business, the system group is defined as "small distributed system". For a long time, these systems have been running locally based on the VMware virtualization infrastructure. While welcoming EOL in turn, their peers considered the issue of migrating to cloud computing.

"We studied different approaches, but this time we decided to migrate to VMware Cloud on AWS because it was difficult to ensure that engineers could rebuild, that currently running applications could not run in the local cloud environment, and that EOL was imminent." (Central Plains)

Take advantage of the L2 extension of VMware Cloud on AWS to complete the migration in limited time and resources

VMware Cloud on AWS is a managed service based on VMware virtualization that runs in an AWS (Amazon Web Services) bare metal environment. Iyu Bank virtualizes the local environment in VMware and has a lot of experience in using AWS in the work of DHD Bank. Therefore, using VMware Cloud on AWS as the best solution for the current transformation is the most effective in terms of cost and speed.

The small distributed system migration project was launched in January 2021. There are no major technical issues when migrating systems running in a local VMware environment to VMware Cloud on AWS. After design, the actual transition work will be completed in April-June, about 2 months.

The system of this migration is five systems running on the basis of three generations of virtualization common [multiple VM (virtual machines) with Windows Server as client OS]. Of these, 2 are bank-wide systems, 3 are headquarters-oriented systems, with 2500 users for all staff and 900 for headquarters. In particular, the systems used by all banks are important systems that are directly related to the banking business.

During the migration, we use "L2 extension" to connect the VMware Cloud on AWS to the inline network used by the existing system through a virtual switch, where the VMware Cloud on AWS consists of a closed area network connected only to the inline network. With L2 stretching, the system on VMware Cloud on AWS is as if it were running locally.

"through the L2 extension, we will not make large-scale changes to the IP address and network configuration that the system migrates to the cloud," said Seiko Ikeda of Iyogin computer Services, the group of Iyu Bank Information Systems. I think this has also made a very great contribution to the significant reduction of test hours with high load. "

VMware Cloud on AWS gradually switches to a production environment through careful migration rehearsals. Before switching, you can use cloud-enabled replication tools to synchronize virtual machines (virtual machines) on the local and cloud, thus switching without affecting the user's business.

This project, due to the restrictions on the movement of the coronal accident, while making active use of Web meetings, etc., while working closely with partner companies. Foyem software can also be supported remotely, and every challenge can be solved quickly, which is the main reason for its success. "(Mr. Central Plains)

Look forward to a substantial rationalization of operational management costs. Explore the unique active methods of cloud computing

Migrating the local system to VMware Cloud on AWS and getting rid of the hardware life cycle in a short period of time is expected to have a good impact on DX's efforts in the future.

"by migrating to VMware Cloud on AWS, the maintenance and operating costs around the hardware and virtualization infrastructure should be significantly reduced in the future," said Koihiko Koike of the systems department of Iyu Bank. So far, the backup and disaster recovery environment that you take the time to plan and run can basically come from the source. In addition, we believe that the virtualization infrastructure management solutions previously cultivated locally can be used directly even in the cloud and will be beneficial to future applications. "

In addition, Masaji Watanabe of Ikigin computer Services said: "the theme this time is to transfer the local system to the cloud in its original form, and to rapidly enhance insufficient resources by adding additional nodes in the future." We will also consider making effective use of the unique advantages of cloud computing. "

We will continue to use VMware Cloud on AWS to promote system cloud migration with local welcome EOL as the center.

"if you want to rebuild locally in the cloud, but encounter difficulties in terms of duration and cost, you have more options by using VMware Cloud on AWS. With this migration, if enterprises using VMware need to continue to use locally running systems after cloud migration, VMware Cloud on AWS is the primary solution. "(small pool)

Industry FINANCIAL SERVICE

Customer profile is headquartered in the local bank in Songshan City, Ehime County. In addition to the inner circle of Seto in Kyushu, China, and Shikoku, with Ehime Prefecture as the center, the domestic store network is carried out in Tokyo, Kinki and Tokai. Also opened an online branch, affectionately known as "Iyogin". Root is the 29th National Bank, which was established in 1878 as the first bank in Ehime County, and ushered in its 143rd year of entrepreneurship in 2021.

In response to user comments on the need to quickly migrate existing systems and applications with fewer resources when migrating a local virtualized environment to the cloud, VMware Cloud on AWS can: I think this is the first solution that needs to be studied.
