Applying professional know-how to data center operation

Data centers are facilities designed to safely operate computers 24 hours a day, 365 days a year without any downtime, and they have become a form of social infrastructure which is essential to people's daily lives.

After the 5G era begins in 2020, it is expected that data center demand will increase, and the market scale will expand. Furthermore, as the market grows, investments in data centers by overseas content vendors and the Japanese domestic manufacturing industry as representative examples will further accelerate.
Currently, there is a strong demand to utilize and train personnel who specialize in the operation of data centers.

BroadBand Tower is combining its data center construction know-how, which includes the cutting-edge "New Otemachi Site" established in the center of the Japanese internet in Otemachi, with twenty years of data center management know-how to offer various one-stop services for constructing and operating data centers.
