About Gakken Products Support Co., Ltd.

We support our customers by using our experience and expertise to help them maximize value in product creation and business initiatives. We off er the following two types of services:
1. Production management and copyright management of magazines, books and other publications, teaching materials, multimedia products, etc., and product safety screening support for customers on a consignment basis.
2. Accounting, HR, corporate services and other office management, including information system management and public relations work on a consignment basis.

Our Business Challenge

We had our system set up on internal systems with file servers based in the cloud, “Amazon Glacier”. Our plan was to eventually move all systems to the cloud. Although we performed regular cost and system optimization, we didn’t have the resources on hand to implement network optimization. For that, we called upon Colt.

Why Colt

We’d been using other providers’ network services before, but decided to switch to Colt for the following 4 reasons:
1. Low cost, low latency and high quality network throughput
2. Colt’s L2 services allowed us to retain our existing IP address structure
3. Scalability (service upgrades can be done without re-installing access circuits)
4. Capable of sub-rate bandwidth upgrades

Colt also guided us through the process of how cost and quality would improve after upgrading to their services, as well as impact on services related to human resources in our IT division.

Future plans

Our customers expect stable and smooth network usability at all times. So far we haven’t had any trouble with Colt’s services, and we look forward to Colt continuing to provide high-quality network infrastructure in the future as well.

We decided on Colt as our network provider in order to optimize our network infrastructure to ensure future scalability, high network quality and value. We give Colt’s services high marks for their high bandwidth and low latency network that provides reliability we can count on.Yutaka Kurihara, Deputy Associate Director, IT System Department, Gakken Products Support Co., Ltd.
