With its business expanding globally, standardizing customer support at Zuken was urgent.


Build a high-quality web access environment using Limelight's Content Delivery and Cloud Storage services.

Powering Global Delivery of High-Quality Zuken Support

Zuken Inc. based in Japan, develops, manufactures and markets IT systems and consulting services that support the advancement of the product design and development process for the manufacturing industry.

Offering cutting-edge electronics engineering solutions for the Internet-of-Things (IOT), Zuken has earned the confidence of manufacturers worldwide. Although the company has support sites for its global users, it was facing challenges with Web access and content delivery and needed to improve overall performance.





“Since we introduced Limelight Cloud Storage Services, we’ve been able to replicate and deliver content in each region. Our users in the U.S., Europe, Asia and beyond can access content from a server close to their own location. If a cache miss occurs, the content is delivered from the nearest cloud server in the network, ensuring reliable and fast content access from any locale.”

Hiroshige Kamakura, Section Manager, Global IT Section, EDA Business Unit - Zuken

Zuken’s Challenge: With its Business Expanding Globally, Standardizing Customer Support Was Urgent

Zuken offers a wide variety of support services to thousands of users in 47 countries around the world via the Zuken Global Support website. The site provides information on new products, offers software downloads, delivers update files, and handles inquiries from users.

However, with its main servers in Japan, people accessing the site from Europe, the U.S. and other locations experienced slow downloads and response times. Recognizing that a Content Delivery Network (CDN) could help, Zuken started using a CDN service in 2012. But the CDN service failed at improving response times and content delivery issues remained a big problem.

Zuken’s Solution: Build a High-quality Web Access Environment Using Limelight Networks Content Delivery and Cloud Storage Services

Zuken replaced its CDN with Limelight Networks Content Delivery and Cloud Storage Services, which now deliver faster, stable Web access and rapid incident response.

Limelight’s CDN maximizes the stability, speed of Web access, and content delivery to any Zuken location around the world while Limelight Cloud Storage Services help reduce operational and management workload. Going forward, management plans to adopt Limelight’s Content Delivery Services for its corporate site as well as to deliver more video content to manufacturing customers. Important features to Zuken include:

Global Reach

Limelight’s CDN ensures reliable and fast content access from any Zuken locale.


Software downloads that once took over an hour are now completed in minutes with Limelight.

High-Quality Delivery

The reliable Web access Limelight delivers is increasing the efficiency of all support operations.

Customer Service

The Limelight support team provided technical support to ensure a smooth implementation.

***The whole is greater than the sum of our parts. Many of our client case studies and products were originally part of Limelight, Layer0 or Edgecast. Limelight acquired Layer 0 then Edgecast to become Edgio, the complete platform you have today, so we’ve aggregated those case studies in a single library.
