Internet Initiative Japan (IIJ)


A flexible edge data centre solution for edge computing


Founded in 1992, IIJ (Internet Initiative Japan) was Japan’s first Internet service provider. IIJ is now one of Japan’s leading Internet-access and comprehensive network solutions providers. IIJ and its group of companies provide total network solutions that mainly cater to high-end corporate customers.

IIJ has built one of the largest Internet backbone networks in Japan that is connected to the United States, the United Kingdom and Asia. IIJ was listed on the First Section of the Tokyo Stock Exchange in 2006.

The Situation

In 2021 IIJ started to develop a MEC solution to complement the 5G roll-out in Japan. 5G and MEC technologies are ideal for applications that require low latency, efficient and reliable communication as well as security. This technology will enable the development and growth of smart factories, telemedicine, autonomous driving, smart farms, etc.


The Challenge

Traditional, centrally-located data centres don’t have the underlying infrastructure necessary for end to end 5G technology to work. 5G technology relies on edge micro data centres located at the source, by the 5G antennas. In many cases, due to lack of space and infrastructure, this means the micro data centre needs to be placed outdoors, in remote locations or even on the roof of buildings.

The Solution

IIJ have now developed DX edge, a flexible edge data center solution that provides the IT and digital infrastructure of edge computing.

It is not only an edge computing platform with high agility and scalability that supports the speed of business transformation, it is also ideal as an onsite IT platform.

Zella Hut, our outdoor micro data centre, is an integral part of the DX edge solution. Zella Hut is water proof, dust proof, UV resistant, and secure. It’s also environmentally friendly and it can be easily connected to either wind or solar power sources. Zella Hut is the ideal choice edge computing solutions for the telecom industry.

Zella Hut in Japan-1-2

At the beginning of 2021 Tokyo was hit by an unusual snow storm that affected many businesses and operations. The Zella Hut was not affected by the snow, the storm or the low temperatures.

“IIJ is the first commercial internet service provider in Japan. We are progressing our service capability of IT and digital infrastructure, including the data center. We’ve been planning to add the micro data center to our data center product line-up. Zella DC is the micro data center we are looking for because it will be one of our edge computing solution enablers. I’m confident that the partnership with Zella DC and IIJ leads our cutting-edge technology and provides more value to our customers.”

announced in October 2021.
