Basic Supports Koyanagi Construction in Cloud Architecture Revamp

Basic Co., Ltd., located in Shinjuku, Tokyo, has recently provided crucial support to Koyanagi Construction Co., Ltd., based in Sanjo City, Niigata. The partnership focused on refreshing Koyanagi's cloud architecture, which is now publicly available as a case study.

Overview of the Collaboration

Koyanagi Construction has been utilizing Microsoft Azure for their IT infrastructure since the dawn of cloud computing. To enhance both operational security and efficiency, they decided to upgrade to a more flexible and secure cloud architecture. Basic Co., Ltd. played a pivotal role in this transition, delivering comprehensive support from the design phase to actual implementation, all while incorporating a zero-trust security model.

Feedback from Koyanagi Construction

Hiroshi Wada, Chief Information Officer

Hiroshi Wada shared insights on the collaboration, stating, "Since 2016, we have fully migrated our core systems to the cloud and operated on Azure. With Basic's meticulous analysis of our existing system conditions, we have successfully reconstructed an optimal cloud environment. The focus on operational visibility and efficiency has fortified our partnership, which is vital for our business growth moving forward."

Yasushi Yoshida, Innovation Promotion Department

Yasushi Yoshida noted, "During the migration process, we had to switch VPN environments simultaneously. This required careful execution to avoid impacting the existing operations while transitioning the VPN and server setups. Thanks to Basic's dedication, we realized a fast and secure cloud infrastructure with minimal issues and in a short timeframe."
